Cold Storage of the Predatory Midge Aphidoletes aphidimyza (Diptera: Cecidomyiidae)
Journal of Economic Entomology, 1990Long-term cold storage of a commercial biological control agent for aphids, the predatory midge Aphidoletes aphidimyza (Rondani), was investigated as a way to reduce rearing costs and to preserve genetically important lines. Prolonged cold storage of last instars in cocoons at temperatures of 1-11 degree C in total darkness was sufficient as an ...

Prey Preference of Aphidoletes Aphidimyza on Acyrthosiphon Pisum: Effect of Prey Color and Size
Journal of Insect Behavior, 2014Color polymorphism in insects as well as factors contributing to its occurrence and maintenance have been of a great interest. Pea aphid (A. pisum) exhibits a noteworthy color polymorphism which occurs as red and green. The preference of the predatory gall midge Aphidoletes aphidimyza (Rondani) for the two color morphs of pea aphid at two life stages ...

Improving aphid biological control with the predator Aphidoletes aphidimyza
2022[ES] El control biológico, por sí solo o como parte de la Gestión Integrada de Plagas (GIP), es un método de control de plagas eficiente y respetuoso ambientalmente. Especialmente en Europa, el control biológico está aumentando en importancia debido a la nueva Regulación sobre el Uso Sostenible de Productos Fitosanitarios, con el objetivo de reducir en

In organically grown sweet peppers, aphids are the most important pest. The wide range of natural enemies of aphids, that are commercially available, is not a guarantee for successful control but rather an indication that this problem is difficult to tackle. Strategies for control vary among organic growers and it is still not known which natural enemy

Abstract In polytrophic ovarioles of Aphidoletes aphidimyza (Diptera : Cecidomyiidae), each follicle consists of a syncytial multinuclear nurse chamber (NC) and an oocyte connected by one cytoplasmic bridge. The number of trophic nuclei (TN) in NC varies from 5 to 14.

ZUR SUCHFÄHIGKEIT DER EILARVEN VON APHIDOLETES APHIDIMYZA (DIPTERA: CECIDOMYIIDAE)
Entomologia Experimentalis et Applicata, 1973Die Eilarven der aphidophagen Gallmücke Aphidoletes aphidimyza tasteten auf der Suche nach ihrer ersten Beute im Schnitt nur 0.76 cm2 der Blattfläche ab, bevor sie verhungerten. Aus dem Sucherfolg bei unterschiedlicher Blattlausdichte ergab sich aber, daß sie die Beute auf einem Areal von 2,70 cm2 erfaßten, also offenbar bereits auf kurze Entfernung ...

Oviposition Site Selection by the Predatory MidgeAphidoletes aphidimyza(Diptera: Cecidomyiidae)
Environmental Entomology, 1999Eggs and neonate larvae of the aphidophagous midge Aphidoletes aphidimyza Rondani are vulnerable to intraguild predation and starvation. The role of A. aphidimyza females in selecting suitable oviposition sites for offspring survival and development was investigated in the laboratory on potato.

Applied Entomology and Zoology, 2012
A solitary endoparasitic species of Pteromalidae (Hymenoptera: Chalcidoidea) was reared from pupae of an aphidophagous gall midge, Aphidoletes aphidimyza (Rondani) (Diptera: Cecidomyiidae), in Japan. The parasitoid was identified as Gastrancistrus fuscicornis Walker, a species that has been recorded from Europe.

Morphology of putative sex pheromone glands and mating behaviour in Aphidoletes aphidimyza
2002Adult emergence period, sex ratio, female calling behaviour, and the risky mating behaviour of A. aphidimyza in spider webs are described. We provide evidence that A. aphidimyza females produce a sex pheromone and attract males, and we give a description of the location and structure of the supposed pheromone producing glands of A.
