Aphidoletes aphidimyza (Diptera: Cecidomyiidae). The aphid midge, Aphidoletes aphidimyza, is a cecidomyiid fly whose larvae are effective predators of aphids. Aphidoline biological control agent contains the predatory midge, Aphidoletes aphidimyza. This voracious midge lays its eggs in colonies of aphids, and the. Aphidoletes aphidimyza is gall midge whose larvae feed on over 60 different species of aphids. These gall midges are mainly used to control aphid colonies.

Adult midges are very efficient at locating aphid colonies.
Adults are small and delicate midges mm. Studies with other aphid predators e. Larvae has orange, legless maggots, up to 3 mm long. Commercial Availability Aphidoletes aphidimyza is commercially available see the off-site publication, Suppliers of Beneficial Organisms in North Americapage of the California Department of Pesticide Regulation website. Aphidoletes aphidimyzathe aphid Predatory Midge is a voracious native predators of over 60 species of aphids.
Larvae need slightly moist soil for successful pupation. Each female may live for one to two weeks and deposit, singly or in clusters, about 70 upright, orange eggs on leaves among aphids. It is supplied as pupae in trays or bottles containing a moist substrate such as vermiculite or peat moss for the pupae to complete their development.
Adults are rarely seen, as they are mostly active in the evening. Plants were grown as in Jandricic et al. Thus, we hypothesized that biological control efficacy could be compromised when more than one aphid species is present. Maple aphids and Episyrphus balteatus deGeer Diptera: To produce aphid infested plants, separate plants received either three adult M.
Journal List Insects v.
Specifically, Jandricic et al. Pansies were generally free of any additional ornamental pests e. Cecidomyiidae by low-intensity light.
Though numbers of A. To determine control outcomes Section 3. For greenhouses apply 2 Aphidoletes per plants. In many cases, aphid populations on individual plants were completely eliminated.
However, on budding plants, populations were concentrated ca. With the exception of a single study on roses [ 8 ], this is the first ahpidoletes of release rates for this aphid predator in ornamental crops. Wraight conducted the statistical analyses. Environmental conditions High relative humidities give better effects. Different letters indicate significant differences between treatments when M.

The average sex ratio over experiments in Section 2. As in Jandricic et al. Plant stratum, aphid species and their interaction were tested. Pests Attacked over 60 species of aphids.
Aphidoletes are used to control aphids indoors in commercial greenhouses and interior plants as well as outdoors in orchards, shade trees, roses and home gardens. For orchards use Aphidoletes per tree. Statistical tests were conducted on log-transformed data, though arithmetic means and SEs are shown.
At all plant stages, aphid species had a significant effect on the number of predator eggs laid.
Environmental Conditions across Experiments Average temperatures in the research greenhouse compartments from the point of A. On day 0 of all experiments, adult A.
All tests were done on log-transformed data, although untransformed means and standard errors are presented. Assessment of aphid colonies by hoverflies.
However, the predator was less effective against A.
