(2R,7S)-Diacetoxytridecane: Sex Pheromone of the Aphidophagous Gall Midge, Aphidoletes aphidimyza
Journal of Chemical Ecology, 2004In a recent study, evidence was presented that females of the aphidophagous midge Aphidoletes aphidimyza (Rondi) (Diptera: Cecidomyiidae) release a sex pheromone to attract mates. Our objectives were to identify and bioassay the pheromone. Coupled gas chromatographic-electroantennographic detection(GC-EAD) analyses of untreated and hydrogenated ...

The aphidophagous gall midge Aphidoletes aphidimyza (Rondani) (Diptera: Cecidomyiidae), a dominant natural enemy of aphids, has been used as a biological control agent in many countries to control aphids in greenhouses. As developmental arrest in diapause lowers the effectiveness of natural enemies, we studied the effect of photoperiod and temperature ...

Sexual dimorphism and sex pheromone detection in Aphidoletes aphidimyza
Animal Biology, 2020Abstract Sexual dimorphism, particularly at the level of sensory and locomotor organs, is usually attributed to sexual selection. Antennae are notably developed in males of species that need to detect a sex pheromone at low concentration or at long distance. In addition to their role in intrasexual selection, antennae can be seen as important ornaments

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.

Impact of Humidity on the Biological Development ofAphidoletes aphidimyza(Diptera: Cecidomyiidae)
Journal of Economic Entomology, 2016Aphidoletes aphidimyza Rondani (Diptera: Cecidomyiidae) is one of the most important predators used in the augmentative biological control of aphids worldwide. However, due to its particular life history, mass rearing A. aphidimyza remains difficult.

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.

Morphology of putative female sex pheromone glands and mating behaviour in Aphidoletes aphidimyza
Entomologia Experimentalis et Applicata, 2002AbstractAdult 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.

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)

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.
