EFFECT OF BUPROFEZIN ON REPRODUCTIVE PERIOD IN PERICALLIA RICINI FAB (LEPIDOPTERA: ARCTIIDAE)

Abstract

Any concentration of the burpofezin applied to adult Pericallia ricini Fab prolonged to sexual maturity. As per statistical analysis, the concentration from 0.0001% to 0.50% among which the preoviposition period varied from 3.12 to 3.32 days, affected this period identically (P>0.05) with less prolonging effect as compared to the 1.00 per cent concentration of the buprofezin with the preoviposition period tasted for 3.86 days. Further, the treatment affected orally with any concentration of this insect growth regulator exerted significant influence on the oviposition period (P<0.05). The oviposition period varied from 1.80 to 7.60 days among different concentration of the burpofezin administered orally and it declined with the advancing concentration.
