- Abstract
Nymphs of anthocorid bugs, Blaptostethus pallescens were evaluated @ against 100, 200 and 300 eggs of storage pest Corcyra cephalonica, in 1.0, 2.0 and 3.0 kg. of rice. Important parameters viz. average emergence of host, per cent emergence, per cent reduction in emergence of host and longevity of bugs were observed. Per cent emergence of adult moths of Corcyra cephalonica varied from 5.0 to 96.77, which corresponded to 94.83 and 0.0 per cent reduction over control, respectively, in response to 10, 20 and 30 bugs used. Per cent reduction in host was positively correlated with the number of predatory bugs (r= 0.89** d.f. = 52). Weight of rearing media was found to elicit a non significant correlation with per cent emergence of host (r= 0.26 NS; d.f. = 54). Regression model Y = 48.6 + 1.54 predators -0.0448 host eggs proposed for per cent reduction in host, versus number of predators and number of host eggs was found best fit.
