Abstrakt: The effect of two rearing cages, a wicker-framed muslin cage and a wooden cage on longevity of adult Anomis leona Schus (Lepidoptera: Noctuidae) was investigated in Entomology laboratory of the Cocoa Research Institute of Nigeria (CRIN), Ibadan at an ambient temperature of 27 ± 3 °C and 70–80% relative humidity. In captivity, the relationship of length of life to adult diet was also investigated to provide information on which to base a laboratory rearing techniques for this pest of cocoa. The adult insect was fed on 10% commercial sugar solution, a formulation required for its gonads maturation. The results showed that the adult A. leona reared in wicker-framed muslin cage lived significantly longer with mean value of 16.2 days and 13.3 days than the adult insect in the wooden cage with mean value of 5.2 and 6.8 days. Virgin and mated males and females of A. leona reared in a wicker-framed muslin cage and fed on 10% commercial sugar solution lived significantly longer than virgin and mated males and females of A. leona fed on ordinary distilled water. The Virgin and mated adults placed on distilled water did not live beyond 5 days. Longevity of virgin male placed on 10% commercial sugar solution ranged 15–19 days with mean value of 16.2 days while that of the virgin female ranged 12–17 days with mean value of 13.3 days.
