Hello,
I have just started my Msc research into oviposition responses of E.
balteatus to different sized plants. However, despite numerous searches
there seems to be no literature on this at all. the Syrphids seem to be
classified either into those that lay in response to aphids and those that
lay in response to plants - end of story. E. balteatus falls into the
former group, however I am finding that in a three choice experiment with
large infested, small infested and unifested plants on offer, syrphids
persistently favour the large infested plants. Indeed it seems to take them
a lot longer to find the small infested plants. Have you any suggestions on
any literature which may be relevant to these findings no matter how
apparently unrelated?
Cheers,
Hannah McDowall
