not sure whether this message from Ximo got through, so I am repeating it:
Dear all,
I do have a question for you all. Bashira Chowdhury, a student, asked me the following:
Hi Dr. Mengual,
I had a quick question on syrphid larvae. It's presumed that syrphid larvae are largely sedentary, but there is some ambiguity present in the literature on this subject. As a part of my work this summer, I thought I could use fluorescent dyes to mark syrphid larvae and track their movements through flower patches. Do you think that the dyes could harm their development? Also would this make them more susceptible to predation?
Fluorescent dyes typically don't affect adult insects, but I wasn't sure about larval insects.
Does any of you have ever used dyes with larvae? Any idea? You can cc Bashira (bashira at uw.edu<mailto:bashira at uw.edu>) with your answers.
