The pea moth Cydia nigricana Fabricius (Lepidoptera: Tortricidae) is a major pest of pea, and one of its natural enemies is the parasitoid wasp Glypta haesitator Gravenhorst (Hymenoptera: Ichneumonidae). This study aimed to identify semiochemical sources exploited by G. haesitator females in their search for an oviposition site. Observations in a wind tunnel demonstrated that G. haesitator females...
The pea moth Cydia nigricana causes major crop losses in pea (Pisum sativum) production. We investigated attraction of C. nigricana females to synthetic pea flower volatiles in a wind tunnel and in the field. We performed electroantennogram analysis on 27 previously identified pea plant volatiles, which confirmed antennal responses to nine of the compounds identified in pea flowers. A dose-dependent...
