and successfully mated them with both reared males and field collected males.
Mating occurred in most species shortly after eclosion, and was followed
by a pre-oviposition period of several days. This system did not work for
all of the species we tried, Syrphus opinator was not successful with repeated
attempts, and a few other, but these were single attempts.</span></font></p>

Thanks for that. Any pertinent information and details would be greatly
appreciated. When you refer to mating, did you actually achieve mating in the
buckets or were the females mated prior to placing them in the buckets?<br>
<br>
Thanks - Chris<br>

I had success mating and rearing a few of the important aphid feeding species
in Salinas a few years ago. Sphaerophoria spp. and Toxomerus spp.were
easy. I used 5 gallon plastic buckets with ventilation in the sides as
well as a sleeve opening and a clear plastic top. I used flowering alyssum
plants for pollen and streaked honey on the sides. I then placed aphid
infested lettuce plants into the cage and the females would readily oviposit on
them. I changed them daily and hatched the eggs in a growth chamber.<br>
<br>
I can provide more details if you would like.<br>

I am in need of any information or advice regarding mating syrphids in
captivity (any species would be fine, although I work with a Pipizine). This
information could be from cage studies or (ideally) under quarantine
conditions. As well, if any of you have any information or records regarding
parasitism of any Pipizine syrphid by any Diplazon species, that would be most
useful, too.<br>
<br>
Thanks very much for your help. - Chris<br>
