Morphology of putative female sex pheromone glands and mating behaviour in Aphidoletes aphidimyza
Entomologia Experimentalis Et Applicata, 2002 Adult 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

Bibliography of the Aphid Predator, Aphidoletes aphidimyza (Diptera: Cecidomyiidae)
Bulletin of the Entomological Society of America, 1982The majority of species in the family Cecidomyiidae are either phytophagous or gall forming. However, the larvae of Aphidoletes aphidimyza (Rondani) feed as predators upon many species of aphids. The adult females are small, delicate midges that are very adept at locating aphid infestations and ovipositing upon leaf surfaces near aphids.

Analysis of Chilling Injury in the Biological Control Agent Aphidoletes aphidimyza
Cryobiology, 1995Abstract A model was used to determine the cooling rate necessary to prevent chilling injury embryuos of the biological control agent Aphidoletes aphidintyza and thus indicate whether conventional cryopreservation (using slow cooling rates is achievable for this species.

Female Aphidoletes aphidimyza confronts serious challenges from both aphid prey and conspecifics. These challenges constitute strong selective pressures on the predatory midge to have an adaptive oviposition strategy. We did laboratory experiments to investigate clutch size of A.

Diapause larvae of Aphidoletes aphidimyza were stored at a temperature of 3 degrees C under continuous darkness for up to 7 months with survival rates above 50%; after storage for 1 year the survival rate dropped to 12%. Diapause was terminated in the majority of individuals within 120 days of chilling under storage conditions. Brief exposure (10-60 s)

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 ...

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

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 ...
