Title: Impact of Plant Characters and Cropping Systems on the Searching Behavior and Parasitization Efficiency of Trichogramma spp. Egg Parasitoids of Helicoverpa armigera
Abstract:The behavior of insect parasitoids is not only affected by the host and by host-produced
cues such as feces or sex pheromones but also by the first trophic level, the hosts' food Plants
(Vinson, 197...The behavior of insect parasitoids is not only affected by the host and by host-produced
cues such as feces or sex pheromones but also by the first trophic level, the hosts' food Plants
(Vinson, 1976; Price et al., 1980). A good understanding of these tri-trophic level
interactions is necessary to optimize the use of natural occurring or augmented
parasitoids and predators of pests insects. The following study was conducted with
Trichogramma spp. (Hymenoptera: Trichograrnmatidae) egg parasitoids of Helicoverpa
armigera (Hubner) (Lepidoptera: Noctuidae) on two host plants, pigeonpea (Cajanus
cajan (L.) Millspaugh) and chickpea (Cicer arietinum L.).Read More
