In the interaction between two ecologically-associated species, the population structure of one species may affect the population structure of the other. Here, we examine the population structures of the aphid Metopeurum fuscoviride, a specialist on tansy Tanacetum vulgare, and its specialist primary hymenopterous parasitoid Lysiphlebus hirticornis, both of which are characterized by multivolti...

aphid parasitoids (braconidae: aphidiinae) in several localities of kerman province, southeastern iran were studied between 2007 and 2008 and 20 species belonging to eight genera were identified. parasitoids were reared from 25 field-collected aphid species occurring on 31 host plant species. in the present study, 83 parasitoid-aphid-plant associations, their aphid hosts, and the respective hos...

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)....
