Effect of temperature and relative humidity on the occurrence of chrysocoris stolli wolf (heteroptera_pentatomidae - scutellerinae) a potential biocontrol agent of cassia occidentalies

Chrysocoris stolli wolf a polyphagous, is found infesting Cassia occidentalies. C.stolli commonly called as cassia occidentalies bug and is a potential biocontrol agent of cassia occidentalies a weed plant effect of various levels of temperature and R.H. on the population of this bug was experimentally observed in laboratory. The optimum temperature at which maximum number of adults and nymphs survived was observed 25+_2 0c.This level match which the field condition of February to April during which average temperature remains 27 0c and maximum activity and breeding occurs in adult bugs population. 60 to 90 percent R.H is found suitable for the survival of this bug.
