i recently solved a fun little bug mystery at work and i thought it might be interesting to write up a step-by-step narrative of how i did so, as a sort of example of the kinds of things i get to do for my job. this is a stupidly long post because i have no editorial self-control so i'm putting the rest under a cut.

the above insect is a bark beetle, one of a series of 6 specimens i found in a drawer at work. they did not have species labels on them, and the collection labels indicated that they were collected in 1997 from "Chinese Cedrus used for artifical christmas trees." the infested wood had been intercepted and the beetles collected and pinned, but whoever was working in the lab at the time wasn't able to suss out the species, which is extremely reasonable because even IDing american bark beetles to species can be a massive pain in the ass, let alone ones from asia.

the beetles were clearly in the genus Phloeosinus based on the shape of the antennae and the large spines on the elytral declivity (the ass area), and whoever pinned them at least got them that far themselves, but determining the actual species was going to be a lot harder. even american beetles in this genus can be devilishly hard to confidently ID to species since they often look alike and also are quite morphologically variable in ways the bleed into each other. they are pretty cool though and those ass spines are usually critical in species-level identification

btw since i'm going to be writing out this word a lot in this post, it's pronounced roughly as "flea-o-sign-us" if you're curious.

determining bark beetle species is often made much easier by knowing what tree the beetle came out of since most bark beetles (but not ambrosia beetles, which are also scolytid/scolytine beetles but a whole other can of worms grubs) are highly host-specific, usually being adapted to only a certain tree species or genus or small group of related genera.

so Cedrus is the genus for eurasian cedar trees, and there is one species of Cedrus native to china, Cedrus deodara, but that seems like an odd choice of plant to harvest and send to america for artificial christmas tree trunks. most actual Cedrus species are from the mediterranean area. however there are also some chinese trees in the cypress family Cupressaceae (+Taxodiaceae) that are called cedars, and in fact most species of Phloeosinus are exclusively found in trees in this family. one likely species is Cunninghamia lanceolata, traditionally called "chinese fir" despite not being a fir but also more recently marketed as "chinese cedar" because that's how common names for species go.

oh and there is also the tree Toona sinensis in the family Meliaceae that's ALSO sometimes called "chinese cedar" for some reason but more importantly also called "beef and onion plant" lmao, but that was an even worse candidate for an artificial christmas tree trunk and also not a known host for the beetles. easily discounted but i had a laugh.

so my first angle of attack was to assume that the collection labels were correct and the beetles were in fact from a Cedrus tree. i was able to find a list of about a half dozen Phloeosinus species known to attack Cedrus cedars, but none of them were native to china. this would most likely mean that one of the mediterranean species had been transplanted to china for cultivation, which is entirely plausible. after digging though a bunch of literature i wasn't able to find a good key for Phloeosinus species in the entire area i wanted, but found a couple regional keys covering geographic ranges that when combined covered about what i wanted. for non-biologists, this is what a species key looks like:

sort of a choose your own adventure kind of thing but for determining a creature's true identity. anyway none of the results i got from these keys led to species who's descriptions matched the one that i had. i should also mention that my specimens had a rather distinctive feature unlike any other Phloeosinus species i'd ever seen before, which was an elytral vestiture consisting of these really funky little black explanate scales:

most Phloeosinus species have some kind of vestiture on their elytra but all the ones i'm familiar with have the hairs and scales light-colored and never shaped anything like this, so i figured that the description of the correct species would surely mention these scales.

so anyway dissatisfied with this avenue, i decided that the next most likely option is that whoever made the labels for the specimens was told that they had come from "chinese cedar" by the importer and had just assumed that meant Cedrus but it was actually one of the cypress family cedars. again most of the described species do in fact use Cupressaceae as hosts.

so next i found this UN report with a (hopefully) comprehensive list of all non-EU bark and ambrosia beetle species that attacked conifer trees. i culled from that a list of Phloeosinus species listed as coming from "asia." since that was too broad of an area, i then looked up all of these species in the species catalogues listed in the report, mostly Alonso-Zarazag et al (2007), though some were also listed in Wood and Bright (1992) or Bright and Skidmore (2002), which i happen to have physical copes of. from these i could narrow the list down to just species found in china.

now things became difficult because there are no keys to chinese Phloeosinus, or at least none in english. also even just written descriptions of many of these species were impossible to find because they were all written like 60-100 years ago and usually in chinese or german or french and had never been translated or uploaded anywhere online. likewise almost none of them had research-grade (or any) photos anywhere online.

so after hours of fruitless digging, the best i could come up with was a guide to scolytine beetles of korea (PDF link), which contained a key with a handful of the species on my list and did include english descriptions of these. now one of the species in the guide, P. perlatus, IS DESCRIBED as having dark scales, and my specimens did seem to land on that species when i ran them through the key. that's promising! and the hosts were on my list of possible non-Cedrus chinese cedars! also promising! buuuut something just didn't sit right with me. parts of the species description in that paper just didn't seem to quite match my specimens, like for example the size was a little off, described as being 2.4-3.4mm long, while all of mine were in the 3.3-3.6 range. plus the photos of the species, while distressingly low-resolution, just didn't look like mine.

okay so that was dissatisfying. i'd managed to whittle down my list of suspects a good deal from what little scraps of information i could find about them through my sleuthing, either the wrong hosts or the ones that did have english descriptions available online like in that korean guide didn't fit, but i was still left with several possible candidates and no way to narrow it down further, of course this all assuming that the beetles i had on my hands even were a species that had been scientifically described and named. bark beetles are a huge group of critters and many are quite understudied, especially in asia, and a bunch of new species are described every year!

i was about ready to just give up, but then by coincidence i had a reason to email a couple of high-level bark beetle researchers about a different beetle mystery i was also working on, which was in a group that they were the authorities on. on a whim, i mentioned my Phloeosinus conundrum to them to see if they had any ideas and they recommended i contact Dr. Roger Beaver. yeah, i know right? fucking kickass name i'm so jealous. sidenote: it's so funny how many bark beetle researchers have extremely appropriate names, like two of the biggest names in the field are Steve Wood and Dave Wood. no relation.

so anyway i contacted Dr Beaver, who had done some research on east asian Phloeosinus in the past and he was kind enough to send me an unpublished provisional key to chinese species that he had written up a few years ago. using that key, i ended up at "P. pertuberculatus (?=sinensis)" which means that there was some suspicion that P. pertuberculatus and P. sinensis were the same species, just described and named independently by two different entomologists (Hans Eggers and Karl Eduard Schedl respectively), as often happened, especially in the glory days of insane 18th-20th century european entomologists describing literally thousands of new species during their careers.

now these two species WERE both on my final list of suspects of chinese Phloeosinus species that hadn't otherwise been eliminated for one reason or another, and both had Cunninghamia "cedar" trees as known hosts. Dr Beaver was then kind enough to scan and send me the original descriptions of these two species:

which i was able to use google translate on:

not the nicest translation but still an admirable attempt on google's part to deal with all the entomological jargon, and most importantly the description of the elytral scales on P. sinensis definitely seems to match my specimens more than the pertuberculatus. plus i found a paper on taiwanese bark beetles (PDF) coauthored by Dr Beaver that had a (also distressingly low-resolution) photo of pertuberculatus that didn't seem to match my specimens:

aaand finally: i'd been trying for days to access the webpage of a chinese museum that popped up as the only notable result on a google image search for P. sinensis but every time the website would time out and the cached version of the image was too small to make out any details on, but it finally occurred to me this evening that the reason was probably because my work computer or work wifi was just automatically blocking chinese websites because of america's insane paranoia about chinese spying, and sure enough i opened it up on my home computer and it fucking worked!

that's a pretty fucking bang-on match for my specimens! the scales look right, the color is right, the size is right, the ass bumps are right, the host is right, the geography is right, and the translated description otherwise seems to match! here's mine again so you don't have to scroll all the way up:

so i'm calling this 26-year mystery solved! not all of the bug puzzles i've worked on have had as meandering of a path to their conclusion as this, but i thought that this one did display a good number of the different methods i use. the biggest thing that was missing was me wandering into my lab's massive library of old dusty entomology journals stretching back over a century and digging out some old article that never got scanned and put online, as often happens, but in this case since the bugs were asian and out library mostly covers north american entomology that wasn't going to be very fruitful.

hopefully this was interesting to... somebody besides myself. if you've read this far and weren't bored to tears then congratulations you probably have the same kind of brain damage as me!

On the night of April 30, 1541, the Ming Ancestral Temple in Beijing was struck by lightning and burned to the ground. [...] 

[T]he fires forced the Jiajing Emperor to resurrect one of the dynasty’s most expensive, difficult, and destructive projects: the logging of old-growth timber in the far southwest of China. Disaster struck again in 1556, when fires burned the Three Halls that form the central axis of the Forbidden City. [...] Yet the lightning strikes in Beijing were also a disaster for the old-growth forests of the southwest, where the logs to build the palaces had first been cut in the early 1400s. As logging supervisors soon learned, ancient trees could not be felled on a regular basis. Officials pressed ever deeper into the gorges of southern Sichuan and northern Guizhou to find them, bringing massive transformations to the environment in the process.

---

The foundations of Beijing were laid between 1406 and 1421 by the Yongle emperor, a junior son of the Ming founder, who moved the court to his personal appanage in north China. [...] Grasping the sinews of power that connected his court to far-flung regions of the empire, Yongle pulled one million laborers to Beijing to build his palaces. Because the weight of Chinese buildings is carried by their pillar-and-beam frameworks (liangzhu), monumental buildings required monumental trees (Figure 2). So Yongle also dispatched a similarly large labor force to the old-growth forests of the far southwest to cut the fir (Cunninghamia lanceolata) and nanmu (Phoebe zhennan) that grew straight and tall enough to be used for imperial construction.

We cannot be certain just how many logs were cut to build Beijing, but the figure must have been astounding.

In 1441, two decades after the completion of the project, 380,000 large timbers were left over from the earlier construction. By 1500, these too were gone, used for repairs or too damaged by rot to be used for construction purposes.

---

In the sixteenth century [when the Jiajing Emperor resumed the project], logging officials wondered how their predecessors had been able to obtain so many giant timbers. Li Xianqing, who supervised more than 40 logging sites in the 1540s, noted that large trees could still be found, but they could only be transported out with great difficulty and at great expense. The majority had to be discarded as hollow or insect-damaged.

Even when a quality log was found, it took five hundred workers to tow a log over mountain passes.

Skilled craftsmen were on hand to build “flying bridges” (fei qiao), stone-lined slip roads, and enormous capstans (tianche) to tow the logs up slopes (Figures 3 and 4). In the remote forests of the southwest, loggers faced attacks by snakes, tigers, and "barbarians" (manyi); “miasmatic vapors” (yanzhang, probably malaria); storms, forest fires, rockslides, and raging rivers (Figure 5). Labor teams had to carry their own food and often starved. At the rivers, logs were tied into massive rafts bound with bamboo for buoyancy, towed by teams of 40 men, and then launched on the three-year, three-thousand-kilometer journey to Beijing (Figure 6). Only a small fraction of the trees reached the capital in a condition where they could be used for palace building.

---

Expeditions exceeded their budgets up to fiftyfold.

One official remarked, “the labor force numbers in the thousands; the days number in the hundreds; the supply costs number in the tens of thousands each year.”

Another saying held that “one thousand enter the mountains, but only five hundred leave” (rushan yiqian chu shan wubai). To make matters worse, logging mostly occurred within territory that was under only loose Ming control [...].

---

The Yongle Palaces were said to replicate the otherworldly atmosphere of the old-growth forests where their pillars originated. The presence of these timbers in Beijing linked the capital, materially and symbolically, to the southwestern landscape of cliffs and gorges where the trees had grown.

But ancient sentinel trees could not be reproduced on demand. The fifteenth-century logging project was a millennial event, removing the growth of hundreds or even thousands of years. Later officials were forced to come to terms with the transformations their predecessors had wrought in the ancient forests. Eventually builders had to switch to smaller, commercially available timber, using ornate artisanship and commercial efficiency to substitute for the austere majesty of the early Ming palaces, and the thousands of years of tree growth on which they rested.

Como cuidar de um Bonsai Metasequoia

Sabia que ... A Metasequoia Bonsai faz parte de um género com apenas uma árvore viva nos dias de hoje.  No entanto, muitos dos seus familiares foram encontrados na forma fóssil. É uma grande árvore no seu estado natural, mas tem sido cultivada com sucesso nas pequenas dimensões de um vaso de bonsai.

Factos básicos sobre Bonsai Metasequoia:

A Metasequoia é uma árvore de crescimento rápido. É originário de Sichuan-Hubei, uma das regiões da China. O seu nome deriva do prefixo "meta", que é de origem grega e significa "perto de". Neste sentido, a sua denominação significa "perto do pau-brasil". Como mencionado acima, esta é a única espécie do género Metasequoia. Pertence à família taxidiaceae. Enquanto a casca e a folhagem são semelhantes ao género relacionado de sequóias, a Metasequoia tem uma característica única: é decídua. É uma árvore de crescimento rápido. Na natureza, pode atingir uma altura de 45 metros. O seu tronco pode medir até quatro metros de diâmetro. As suas folhas estão separadas por 3 cm, que são de um verde profundo, mas tornam-se castanhas no Outono. A Metasequoia bonsai provém da família Taxidiaceae. Esta família botânica é constituída por árvores monóicas que podem crescer até uma grande dimensão. Uns têm folhas que caem e outros têm folhas persistentes. Inclui os seguintes géneros: Cryptomeria, Cunninghamia, Glyptostrobus, Sciadopitys, Sequoia, Sequoiadendron, Taiwania, Taxodium e Metasequoia. Em tempos recentes, alguns botânicos eliminaram esta família e colocaram-na na família Cupressaceae. Nome científico O seu nome científico é Metasequoia glyptostroboides. Tipos e Espécies de Metasequoia glyptostroboides | Nomes comuns Dentro da Família Bonsai Metasequoia glyptostroboides podemos encontrar as seguintes espécies: Bonsai Metasequoia ou também conhecida como Bonsai Metasequoia glyptostroboides Não existem outras espécies deste organismo vegetal. O único espécime do género Metasequoia no planeta é o já mencionado Metasequoia glyptostroboides. Outras árvores relacionadas com esta planta estão agora extintas e só foram encontradas sob a forma fóssil.

Qual é a origem da Metasequoia Bonsai? É originário da China, da região conhecida como Sichuan-Hubei. Qual é a melhor localização e clima para a Metasequoia Bonsai? Deve ser ao ar livre durante todo o ano. Deve ser protegido das geadas no Inverno. COMO CUIDAR DE UMA ÁRVORE Metasequoia Bonsai? Cuidados básicos O cuidado de um Bonsái deste tipo envolve tanto uma poda escrupulosa como uma desfoliação. Isto porque eles estão a crescer rapidamente. Portanto, é necessário equipar-se com as ferramentas de bonsái que o ajudarão a realizar esta manutenção. É um bonsái com o qual podem ser feitos os seguintes estilos: - chokkan (vertical formal) - yose-ue (estilo floresta plantados vários juntos) Temperatura Bonsái Tem tendência a preferir climas quentes e no ambiente natural pode resistir muito bem ao tempo frio. Contudo, na escala do bonsai é mais fraco no frio extremo. Por conseguinte, deve ser abrigado no Inverno. Que tipo de substrato é adequado para o Bonsai? A Bonsai não é uma planta exigente no que diz respeito ao substrato. Se assim for, é habitual utilizar uma mistura de 100% akadama, uma mistura de 70% akadama e 30% de cascalho vulcânico. Quanto e com que frequência o Bonsai precisa de ser regado Bonsai precisa de rega abundante durante todo o ano.  No entanto, parar de regar quando tiver perdido as suas folhas. Tolera uma certa quantidade de alagamento das suas raízes. Quando fertilizar Metasequoia Bonsai Faça isto da seguinte forma: adicione fertilizante durante a Primavera e o Outono, reduzindo a dose no Verão. Quando se deve replantar a árvore Bonsái Ao transplantar bonsai, é importante lembrar que isto só pode ser feito no início da Primavera. Este é um momento delicado para a árvore. É melhor usar um pote de bonsái que retenha a humidade. Quando e como podar uma árvore bonsai A poda é feita entre Outubro e Março. Ou seja, quando as plantas estão em folha. Trata-se, portanto, de uma poda estrutural. Os rebentos provenientes da base do tronco devem ser cortados.

Sobre o Bonsai Wiring and Pinching O trabalho de cablagem é realizado entre a Primavera e o Verão. Os fios devem ser removidos se a casca parecer afectada. Importante: as árvores recém transplantadas não devem ser aramadas (esperar cerca de 4 meses de crescimento vegetativo).  A clipagem deve ser realizada durante todo o período de crescimento vegetativo na árvore.

this the funniest shit i have ever seen

Weibo posted text and image spoilers for chapter 36 so i used a translator to see what it said on a whim. Since Sugiki’s name in kanji (杉木) is a type of tree in Chinese, it kept translating his name into either “Chinese fir” or its scientific name “Cunninghamia lanceolata”:

(Fusako’s name quite literally means “the house” in Chinese but it wasn’t as funny as C u n n i n g h a m i a L a n c e o l a t a. And I’m also surprised that it translated the part about Suzuki’s dancing pretty well.)

Zinc and Chelation

When zinc ions enter in contact with other substances such as hinokitiol, Pyrrolidine DioThioCarbamate (PDTC), and zinc pyrithione (PT) it exerts a dynamic response which promotes antioxidant, anticancer, and antiviral response. Hinokitiol is an essential oil of from the wood of Cupressacea trees. This oil, when it enters in contact with zinc it elicits the interchange of zinc ions and stops viral replication, in this instance SARS-CoV, and inhibits lung cancer cell growth. Cupressacea trees refers to Cypress, it has 30 genera and 133 varieties. It includes the following trees: Fitzroya, Pilgerodendron spp, Arbovitae spp, Austrocedrus, Cupressus spp, Callitris, Widdringtonian spp,Tetraclinis, Thujopsis, Chamaecyparis spp, Calocedrus, Juniperus spp, Athrotaxis, Cryptomeria, Cunninghamia, Sequoiadendrum, Sequoia, Metasequoia, Taxodium. DPTC is a metal chelating agent that passes through the blood brain barrier and stimulates astrocytes, regulates production of glutathione, increases copper at a cellular level, and regulates nitric oxide synthetase. DPTC targets the hippocampus as well. DPTC has been shown to reduce effects of Alzheimer and stop viral replication of SARS-CoV. PT is zinc pyrithhione and has been noticed that in combination with zinc2+, hinokitiol, and PDTC it inhibits replication of SARS-CoV. It can be assumed that a regime involving vitamin/mineral supplementation, a good diet and hygiene, plenty of rest, and use of essential oils can be our best allies in staying healthy.   References:   Jin-dong Qin, Zhi-hong Cao, Xue-feng Li, Xiao-lin Kang, et al.
