  Which genes or markers can be used to see if there is a genetic variation caused by contamination?

  I'm trying to use chironomidae to see if contamination in rivers change or cause variations in genes, I have read that CO1 and some ferritin genes could be used.

  For anyone dealing with Ephemeropterans: is there someone working with Caenidae?

  Does anyone known where can I get a stock of "clean" Caenis larvae specimens to develop an ecological study? I mean I need lab-growed specimens. Or do you know the best way to get the eggs forDoes anyone known where can I get a stock of "clean" Caenis larvae specimens to develop an ecological study? I mean I need lab-growed specimens.

I would love to see those thalli! They may occur only in some species because certain Orphella may be highly specific to their hosts, although i have observed more often a genus-or family level specificity. Could you mount some of those anal gills in a microscopic slide? or could you take some pictures? That would be great! Maybe you are looking to a new species! That's amazing! Laia

Will e g 500 g Neems seeds extracted in 2 l water at 25°C, 12 hr then diluted with 5 litre water and sprayed with a dosage of 5 litre per acre be correct, too little or too much. Does it depend on where the Neem tree grew that delivered the seeds ? There is a lot of litterature on neem extracts, but a lot of this is grey, you cannot really see what was done, why it worked or not. There is a need to move this from magic to science. It surely is possible I met a Belgian company a few yeras ago that registered neem oil extract with FAO and defined how much there needed to be of several constituions and how to measure them !

  Is it possible to separate species using ITS1 and ITS2?

Besides the asociation between the nymphs and adults is another problem too. We need an easy tool to that helps us asociate both states and help us differentiate the species, so we think that maybe with ITS we could do it, but its not working.

  Does anybody know the scientific name and/or ecology of this eupelmidae? I found it inside of adult Saissetia oleae.

  I found this insect on Citrus lemon and Olea europea in Quillota, Chile, niche sharing with Coccophagus spp, Metaphycus spp and Scutellista caerulea.

All of my efforts to solve the problem were unsuccessful up to now. The two species are very similar and variable in size and colour. Can someone tell me an infallible distinguishing mark to discriminate one species to the other? At the best, appropriate for males and females. Skills in insect morphology are available. I am grateful for any help! Yours sincerely Ronny Reimer
