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.

However, the predator was less effective against A. Our levels of control were achieved using the lower-end of previously reported aphidimza rates of A. 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.

To produce aphid infested plants, separate plants received either three adult M. Although multiple prey species can potentially have positive outcomes for biological control programs using natural enemies [ 1 ] the reverse can also be true aohidoletes.

Conflicts of Interest The authors declare no conflict of interest. They feed by biting aphids and paralyzing them with a toxin before sucking out the aphid body fluids. In a randomized complete block design, aphidimysa corn Zea mays var.

Aphidoletes aphidimyza – Wikipedia

Each female may live for one to two weeks and deposit, singly or in clusters, about 70 upright, orange eggs on leaves among aphids.


In all cases, greenhouse compartment, and greenhouse bench nested within compartmentwere included as random effects to control for compartment to compartment and block to block differences. Cole crops, potatoes, greenhouses, backyard gardens, ornamentals, orchards, berries. Experiments at different stages of plant growth were conducted separately due to experimental design constraints.

Rhodes University; Grahamstown, South Africa: Gillespie3 and John P. Tailored advice can be provided if information is available on the local factors that need to be taken into account, such as the crop, the climate conditions and the level of infestation.

Aphid midges are native to much of North America and will overwinter, although winter mortality may be high. In one study, the Aphidoletes located the one infested plant out of Adults also qphidimyza a source of honeydew for feeding and to improve egg laying. Once they are placed in the greenhouse they usually emerge from the shipping container as adults to begin egg-laying in 3—7 days depending on temperature. Aphididaeon collards Oleracea L. Taxonomy, biology and assessments of field populations.

The gall midge Aphidoletes aphidimyza is a specialist predator that occurs naturally in Europe and has been successfully used for aphid suppression. Plants were considered vegetative as long as new growth at the meristem apidimyza not producing buds at the time of A.

For the between-plant analysis, numbers of eggs and larvae per plant were initially modeled against aphid species, as well as aphid density since density is known to potentially affect A. Our study illustrates that suitability of a natural enemy for pest control may change over a crop cycle as the position of prey on the plant changes, and that prey preference based on within-plant prey location can negatively influence biological control programs in systems with pest complexes.

Stars indicate significant differences between aphid species within sampling day. However, longevity was significantly affected.

Plants were A vegetative; B budding; or C flowering. Visual effect Aphids killed by the larvae hang on the leaf, connected by their mouthparts. Introduction Although multiple prey species can potentially have positive outcomes for biological control programs using natural enemies [ 1 ] the reverse can also be true e.

Ecological interactions affecting the efficacy of Aphidius colemani in greenhouse crops. Aphidoletes larvae are voracious native predators of over 60 species of aphids.
