[Syrphidae] Mating syrphids

[Bergh, Chris]

Bill,

 

Thanks very much for that. Any information at all is very useful at this
point. I met Mario a few years ago, while he was working on his
dissertation, and will get in touch re: his pubs.

 

Cheers - Chris

Hi Chris,

 

Yes we did placed virgin reared females in the cages 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.

 

You might also wish to contact Mario Ambrsinio
(ambrosim at science.oregonstate.edu), I don't know if he is on this list,
but did some syrphid mating work at Oregon State and published a couple
syrphid papers in the last 2 or 3 years.

 

Good luck,

Bill

Bill,

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?

Thanks - Chris

Chris,

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.

I can provide more details if you would like.

Greetings,

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.

Thanks very much for your help. - Chris
