Abstract: Hunter reduviids have been distributed both in tropical and temperate regions in India. Rhynocoris marginatus (Fab.) and Rhynocoris fuscipes (Fab.) (Insecta: Hemiptera: Reduviidae) have been distributed in semiarid zones, scrub jungles, agro-ecosystem and tropical forests and hence, they have a lot of possibilities of facing environmental crisis. Moreover since these two reduviids were considered as a biological control agents of many economically important pests, augmentative release is an imperative one. The present investigation was under taken in the laboratory to find out the impact of constant temperatures (10, 15, 20, 25, 30 and 300C) and fluctuation temperatures (29 + 1.50C) on eggs and nymphal development and survival rate, sex ratio fecundity and hatchability at lower and higher threshold temperatures, morphometry and morphogenesis, autochthonous gut bacteria and their enzyme production and gut enzyme profile of crude whole animal carbohydrate, protein and lipid content, and immunogenic activity of whole predator DNA content and its polymorphism. Irrespective of the predators and exposure periods, constant temperatures gradually decreased when the egg hatching periods from lower temperature to higher temperature. However, the egg survival ability was diminished between 10 to 200C, 10 - 150C, and 350C were not suitable for R. marginatus and R. fuscipes development. However, the nymphal developmental periods of these two reduviids were significantly diminished from 200C to room temperature. It was also attributed in the survival rate of nymphal instars that constant temperatures were not have any impact on the ii sex ratio of the two reduviids. All the tested temperatures were always in favour of female biased sex ratio.
