Application of Spatial Analysis in the Incidence of the Gall Midge in Jamaican Hot Pepper Production
… production due to a quarantine pest -- the gall midge (Contarinia lycopersici; Prodiplosis longifila). There is a threat of gall midge introduction into the United States, where the insect pest is not known to occur. This research tests the significance of a range of variables to gall midge …

Investigation into the effects of parasitoids on a gall midge Dasineura sp. (Cecidomyiidae), a biological control agent of Australian myrtle, Leptospermum laevigatum
… The second agent a Dasineura sp (Cecidomyiidae) gall midge whose origin in unknown but was probably introduced accidentally. As it was not screened before release an investigation into the effect of parasitism on its effectiveness as a control agent is important. Midges were found to select …

Patterns of parasitism and emergence in the gall midge Dasineura Dielsii (Diptera: Cecidomyiidae) : a biological control agent of Acacia cyclops in South Africa
… 2002 as a biocontrol agent for A. cyclops. This gall-forming midge destroys inflorescences and prevents seedpods from forming, but allows continued harvesting. Insects overwinter as larvae within their galls. This study examined the levels of parasitism experienced by dormant D. dielsii larvae, …

Biological and Agronomic Aspects of Two Insect Predators of Switchgrass
… tiller and rhizome loss. The switchgrass midge (Chilophaga virgati Gagné: Diptera: Cecidomyiidae) feeds above the last internode of the tiller, causing seed yield and biomass loss. There were two objectives for this study: (1) to determine genetic and temporal variation among cultivars for …

Olfactory responses of Dasineura Dielsi Rübsaamen (Diptera: Cecidomyiidae) females to host plant volatiles
… Dasineura dielsi (Diptera: Cecidomyiidae), a gall midge, was introduced into South Africa as a biological control agent on the invasive alien plant species, Acacia cyclops (Mimosaceae). An investigation was launched to test the following hypotheses: 1) the midges respond to the scent of A. …

The role of chemicals in the location of host plants by midge pests of UK fruit crops
Gall midges (Diptera: Cecidomyiidae) are important pests of many horticultural crops. They are difficult to control by conventional means as the larvae develop in galls surrounded by plant tissue. Gravid females need to locate suitable host plant material on which to lay their eggs and there is …

Ecological and Evolutionary Consequences of Variation in Clutch Size in Asteromyia Carbonifera (o.s.) (Diptera: Cecidomyiidae)
The gall-midge Asteromyia carbonifera induces blister-like galls on the leaves of Canadian goldenrod, Solidago canadensis (Compositae). Female midges deposit one to five offspring per gall. During their brief adult existence, females produce a number of galls. The number of eggs laid at each …
