RE: SYRPHID PREDATORS ON WHITEFLIES (ALEYRODIDAE)
I have a large paper on prey of the larvae of Indian Syrphidae publis=
in _Tropical Pest Management_ in 1980 or 1981. I do not have access to =
here and am relying on my memory. This paper has extensive references to=
other papers on this subject.
One or more species of our own <Allograpta> have been also recorded
feeding on whitefly immatures in southern India. A species of "<Allobacc=
I have reared on whiteflies on <Bauhinia> trees near Bangalore. And proba=
<Paragus> too ?
But, the most efficient Dipteran predator of our whiteflies in this
sub-continent is <Acletoxenus indicus> which is a tiny Drosophiidae fly. =
is very efficient when its populations are plentiful in the infested
Being also a Coccinellidae (Coleoptera) specialist I can tell you th=
species of <Catana> are also very efficient predators of our whiteflies h=
besides the polyphagous <Menochilus sexmaculatus>. I must get back to my
databases on our Syrphidae and Coccnellidae and can ofer more information=
then, if needed.

Yes, there are a number of species of syrphid (Syrphinae, tribe Syrphini)=
which are known to predate whiteflies.
Many species of the genus Ocyptamus do. Common in the West Indies and
southern Florida is ferrugineus which I described in my West Indian
In Australia, we have a species of Allograpta which is also white fly
predator, but the Australian Journal of Entomology decided to reject our
paper on that subject as it was deemed insignificant!
And finally, we now know of a syrphid maggot which lives amongst
whiteflies, taking their "honey dew," and using it as a bait to attach
flies, which it eats instead of the white flies!
Please try to rear your white fly predator, and we* will be happy to put =
name on it, etc.
*the "we" is equal to Graham Rotheray, Geoffroy Hancock, Manuel Zumbado,
various parataxonomists and students at Univ. Costa Rica, who are trying =
take a comprehensive treatment of MesoAmerican flower flies, etc.
