Prey-predator Interaction and Info-chemical Behavior of Rhynocoris fuscipes (Fab.) on Three Agricultural Pests (Heteroptera: Reduviidae)

Abstract: Diversity, ubiquity of anti-predator adaptations has an important direct effect of info-chemical based phenomenon of prey and predator as well as prey density. This work explained three agricultural pests having info-chemical cues also influence the predatory efficiency of the reduviid predator of Rhynocoris fuscipes (Fab.). In this context, the aim of this study was to identify the prey-predator interaction with specific chemical cues on biological control agent of Rhynocoris fuscipes treated with three agriculturally important pests. The polyphagous reduviid predator Rhynocoris fuscipes (Fab.) (Heteroptera: Reduviidae) is a potential biocontrol agent for the red cotton bug Dysdercus cingulatus (Fabricius), tobacco caterpillar, Spodoptera litura (Fab.) Lepidoptera: Noctuiidae) and castor pest Achaea janata (Linn.). The influence of info-chemicals from these three species of groundnut pests on the prey-searching and probing behaviour of the reduviid predator was studied. The water fraction of the mixture of chloroform and methanol extract of A. janata elicited maximum response in R. fuscipes when compared with S. litura and D. cingulatus. Adults and fifth instars were consumed more time with A. janata extracts as compared to other instars. Minimum and maximum response was observed in case of S. litura and D. cingulatus extract. Among the five life stages fifth and adult stages of the R. fuscipes predators preferred fifth instar of A. janata, S. litura where as fourth and fifth nymphal instars were quickly preferred third to fifth instars of D. cingulatus. These findings could be used in the application of R. fuscipes as a biocontrol agent in the management of cotton, castor and groundnut pests.
