Do interactions between plant roots and the rhizosphere affect parasitoid behaviour? [PDF]

open access: yes, 2004
Multitrophic interactions are powerful forces shaping the structure of living communities. Plants encounter a great diversity of organisms in their environment: some of these interactions are beneficial (e.g. symbiotic fungi and insect pollinators) while

Mating behaviour of Aphidius ervi (Hymenoptera: Braconidae): The role of antennae

open access: yesEuropean Journal of Entomology, 2002
In the mating behaviour of Aphidius ervi Haliday the antennae play a pivotal role in partner recognition and acceptance. Mating failure was always observed when antennal contact was experimentally prevented. The male of A.

The effect of the quality and size of host aphid species on the biological characteristics of Aphidius colemani (Hymenoptera: Braconidae: Aphidiinae)

open access: yesEuropean Journal of Entomology, 2008
A suitable host provides, at least, the minimum nutritional and physiological conditions for the development of the immature stages of a parasitoid. Host quality may influence the developmental time, mortality rate, longevity and fecundity of parasitoids.
