Few empirical studies have directly explored the association between Buchnera aphidicola (Enterobacteriales: Enterobacteriaceae), the primary endosymbiont of aphids, and the life history strategies of aphid parasitoids. A series of paired-choice experiments were conducted to explore the preference of the parasitoid Lysiphlebus ambiguus Halliday (Hymenoptera: Aphididae) for symbiotic and aposymb...

The flower fly species, Eupeodes nuba (Wiedemann, 1830) (Diptera: Syrphidae) is crucial for agroecosystems as it provides various ecosystem services such pest control through the use of predatory larvae and crop pollination by adults. In this research, consumption rate different instars Aphis fabae (Scopoli, 1763) E. has been studied under laboratory conditions at 25±2 °C, 60±10% humidity (RH)....

all species in the genus lysiphlebus förster (hymenoptera: braconidae, aphidiinae) are solitary endoparasitoids of aphids, which are one of the most difficult and unknown taxonomic groups to identify. a pair of species-specific primers as a molecular marker was designed to identify the most abundant and important aphid parasitoid wasp, l. fabarum marshall, collected from guilan province (iran)....

Cold storage is a valuable method for reducing the cost of producing large amounts of biological agents. Fluctuating thermal regimes (prolonged exposures at low temperatures combined with periodic short higher temperature) are reported to improve cold survival and fecundity in some parasitoid species. In this study, the pupal stage of the parasitoid wasp Lysiphlebus fabarum (Marshall) (Braconid...

The toxicity of three insecticides to Lysiphlebus fabarum (Marshall) (Hymenoptera: Braconidae: Aphidiinae), a parasitoid of Aphis fabae Scopoli (Hemiptera: Aphididae), was investigated using IOBC/wprs protocols. Abamectin 1.8 EC, imidacloprid 350 SC, and pymetrozine 25 WP were tested under laboratory conditions at recommended field rates. Immature stages of the parasitoid were exposed to materi...
