Topic > FEEDING BEHAVIOR OF REDUVIID PREDATORS, RHYNOCORIS...

IntroductionThe reduviidae family constitutes predatory insects with a deeply voracious lifestyle that allows them to successfully colonize and perpetuate their offspring in severely hostile environmental conditions. With almost 6,800 described species (Hwang and Weirauch, 2012), they constitute the largest group of predatory terrestrial insects. Their unbroken streak of success in surviving, occupying and inhabiting extreme conditions is due to the culmination of various factors including structural, physiological, morphological and behavioral adaptations, the constant improvement of their prey capture strategies and a highly evolved feeding method which includes digestion facilitated by their poisonous saliva. Their wide representation has been recorded in tropical and subtropical regions, including deserts and rainforests (Ryckman, 1954; Miller, 1959). Other unusual habitat areas in which they appear to thrive include tree bark, herb foliage, decaying logs, mammal burrows, scrub, agroecosystems, anthills, termite mounds, spider webs, bird nests, rat burrows, human habitation (Haridass, 1985; Ambrose, 1999; Readio, 1927; Louis, 1974; Subramanian and Sahayaraj, 2012; of food production on the other, recent decades have witnessed a surge in the study of predatory insects that could potentially help curb the rampant insect pest population leading to the loss of hectares of crops. In such a scenario, reduviidae have occupied the center stage by proving themselves as important biological control agents against many and...... half of the article ...... a Journal of Agricultural Research. 44(4):281.
