LIFE TABLE ANALYSIS OF ANTILOCHUS CONQUEBERTI FABR. (HEMIPTERA: PYRRHOCORIDAE) IN LABORATORY CONDITIONS

ABSTRACT Life table of Antilochus conqueberti Fabr. (Hemiptera: Pyrrhocoridae), a potential predator of Dysdercus cingulatuswas studied with the data being constructed and analysed under laboratory conditions. The study paved the way for comparing the nymphal mortality and adult longevity for three generations and the mean values were found which proved that the mortality rate in nymphal stage differed with the mortality in adult stage. The mortality rate was at its high during egg stage (9.23%)and III instar (4.95%) and the mortality rate dropped when the organism crossed IV instar (2.37%) and V instar (0.97%). It was also revealed that 77.2 % organisms survived until the attainment of sexual maturity and took part in reproduction. REFERENCES Ali, A, P.Q. Rizvi, 2009.
