I found this little man on my banana, and I gave him some to share! Any clue what he is? I think he's some kind of isopod but he was so tiny it was hard to get good photos

Mealybug ID - FL, USA:

Hello, yess, this looks like the Long-tailed Mealybug (Pseudococcus longispinus), family Pseudococcidae. They are common in Florida, and other tropical and subtropical parts of the world, often found in greenhouses and on farms.

It can be control using Malathion, spirotetramate, imidacloprid, chlorpyrifos, buprofezin, carbaryl and so on.

@lowpolygons​ submitted: Hi Taylor onenicebugperday ! Today i helped bring this bug outside because it was in a classmates flower she was going to use for a project. I was wondering what it was ? Im thinking closely related to silverfish ? But i may be wrong! So could you help me ID them? Location (please remove) is: [removed] (metropolitan region).

Have a wonderful day 💖

Hello! This friend is a mealybug, which is a common plant pest and true bug. Specifically, I would thing a long-tailed mealybug in the genus Pseudococcus. But those little tails do remind me of a silverfish, too, so not a bad guess!

#1477 - Cryptanusia sp. - Mealybug Encyrtid

I had to get this photo off WaspWeb, since the photographs of the one spotted in Yanchep, north of Perth, by Shelly Jordan, were too fuzzy to use. Link to her surprisingly much sharper video here 

That didn’t stop me getting an ID, since the bladed antennae are pretty distinctive, but I did have to ask around - the Encyrtidae are not a very popularly-known family, but extremely important in the field of biological control. 

There’s at least 3700 described species in the family, and about 450 genera. Most are parasitoids of butterflies and moths, but details of the life history can be variable - some attack lepidopteran eggs, some attack caterpillars, others are parasites of existing parasites (and some Encyrtidae develop as parasitoids of ticks).  A number are used as biocontrol agents, but some are ecological threats- the endangered Jamaican Swallowtail loses over 3/4 of its young to Encyrtid parasites. 

Some species display "polyembryony" in which a single egg clones itself inside the host, eventually producing large numbers of identical adult wasps. But even more remarkably, some of the larvae never reach adulthood - they are soldiers, hunting down and killing unrelated larvae, to protect their smaller clone-siblings.

Cryptanusia aureiscutellum is an Australian species - one of about 5 in the genus - used in greenhouses and indoor plantings against longtailed mealybug (Pseudococcus longispinus), parasitising the younger instars, or sucking out their juices. It was introduced to California for that purpose, but since it’s also showing up in Spain, it may well have spread much further than that.

Graduate position: UEdinburgh.SelfishGenes

Dear all, I would like to advertise a PhD project on the evolutionary and reproductive genetics of insects in my lab at the University of Edinburgh starting October 2019 http://bit.ly/2A0EYcn. There are funding options for both UK and international students. If you are interested please contact me directly (laura.ross@ed.ac.uk) to discuss. Deadlines vary depending on funding source (13th of December for non-UK, 10th of January for UK), but please contact me at least a week before the official deadline if interested! http://bit.ly/2BQcogg The evolution of a $B!H(Bselfish$B!I(B chromosome Dr Laura Ross (laura.ross@ed.ac.uk) and Dr Konrad Lohse (School of Biological Sciences, IEB, University of Edinburgh) A project summary Selfish chromosomes increase their transmission to future generations at the expense of other genes in the genome. This project studies how they affect the reproduction and evolution of an insect. Project background Selfish genetic elements are stretches of DNA that increase their own transmission to future generations at the expense of other genes in the genome. Such elements are widespread, yet how they increase their transmission and affect the evolution of the species in which they are found remains poorly understood [1]. The aim of this project is to understand these questions by studying the behaviour of a $B!H(Bselfish$B!I(B B chromosome in mealybugs [2] -- small plant-feeding insects (figure 1a). This chromosome is not essential to the survival of these insects and is actually harmful as it reduces their fertility. Instead the chromosome spreads through populations by manipulating male reproduction to increase the rate at which it is included in sperm (figure 1b). However, not all individualds seem equally affected and some show resistance against the B chromosome, possibly limiting its spread [3] (figure 1c). Key research questions The aim of this project is to understand how a $B!H(Bselfish$B!I(B chromosome spreads through populations. How it manipulates the insect$B!G(Bs reproduction to its own benefit and how it affects the evolution of resistance alleles in populations where it occurs. The tractability of the study system and the genetic tools provide a unique opportunity to understand how selfish genetic elements can shape the way animals reproduce. Methodology and timeline This project will combine laboratory experiments, microscopy, gene expression and genome analyses. There is also scope for tracking the evolution of the B chromosome in natural populations.The first year of the PhD will focus on training in the required techniques and generating sequence data, the second and third years will involve conducting large- scale laboratory experiments and possibly collecting and analyzing wild specimens.The final year will focus on finishing the analyses and preparing manuscripts to disseminate the results Training A comprehensive training programme will be provided comprising both specialist scientific training and generic transferable and professional skills. Specifically the student will undertake training in the use of molecular wet lab techniques, the analysis of sequencing data and the use of microscopy and cytogenetic approaches. Requirements Candidates must be highly motivated with a keen interest in evolutionary biology and genetics and a strong motivation to pursue a scientific career. Previous experience with genetic techniques and genomic and/or theoretical analyses would be an advantage. Further reading [1] Hurst, G. D., & Werren, J. H. (2001).

http://dlvr.it/Pkzjg1

[drhoz]

Insect of Australian origin, photographed for the first time in Spain on 06/27/2011 by José Marín Herrera, and identified through the Virtual Insectarium portal of the Photography and Biodiversity platform, by Encyrticidae expert, Antoni Ribes Escolá on 02 / 08/2011. The average size of the insect is 1.5 mm, plus another millimeter its antennae. It is a parasite of the Pseudococcus or mealybugs, so it was introduced in California for the biological fight against them.
