Hello all,

I have an MS student who is finishing up his thesis on aspects of the intraguild interactions between the Pipizine, Heringia calcarata, and the parasitoid of its woolly apple aphid host, A. mali. As part of his studies, he used choice and no-choice feeding experiments comparing the number of aphids consumed in relation to their stage of parasitization (non-parasitized, early stage of parasitization, and mummified aphids), and found significant effects. I am aware of syrphid studies looking at oviposition discrimination by female flies according to parasitism, but am wondering whether any of you know of other studies on larval discrimination?

Dear all
Here is some information from Anatolii about a couple of things to do with the symposium.
“I have consulted with our administration and I can help with visas only for Novosibirsk and the excursion to Teletskoe Lake. Those colleagues who would like to go elsewhere in the Altai after the symposium, I will help as much as I can, but I cannot help anyone to go to the border areas, which requires a long and detailed process for permission. At least one group is planning to go to Semibskii Pass and its environs, which should be fine.
“We decided to go overnight by coach to and from Teletskoe Lake in order to save time and money on the hotel. Although it is not very comfortable to sleep on the coach, by doing so we save two days for collecting insects, plus we do not have to spend money on extra nights in the hotel.
“If anyone would like to stay in Novosibirsk after the 26th June, we can reserve additional rooms in the hotel in the city of Novosibirsk.”
Best wishes
