| Abstract: | The braconid parasitoidMeteorus rubens (Nees) is a gregarious larval parasitoid ofAgrotis ipsilon (Hufn.). An olfactometer was used to check the attractiveness of the parasitoid to Hexane extract (kairomone) of its host that could be used in conjunction with releases of natural enemies. Female wasps are attracted in high numbers to the kairomone, compared with males. Respective rates of 94.3 and 22.3% are reported. In the control (no kairomone was used), the corresponding figures are 5.7 and 3.3%. |
