Abstract:

The methanol extract from leaves of Aegle marmelos was investigated to control insect infestation of stored food commodities viz. maize, rice, cowpea and wheat flour during from Ostrinia nubilalis, Spodoptera littoralis, Callosobruchus maculates and Tribolium confusum. After introducing the test insects, stored food samples were fumigated with methanol extract from leaves of Aegle marmelos at 500 μg/mL (ppm). The methanol extract significantly enhanced feeding deterrence in insects and reduced the grain damage as well as weight loss in fumigated food samples infested with all insects. The methanol extract at different doses significantly reduced oviposition and adult emergence of these insect pests. Regression analysis of data on individuals in treated food samples confirmed that significant reduction of oviposition and adult emergence of insect pests decreased with increase in doses. At 10 ppm and after 72 hours of incubation O. nibilalsis, S. littoralis, C. maculates and T. confusum the hatching percentage was 80.85%, 79.85%, 81.07% and 78.81% respectively. The hatching of larvae showed a decreasing trend on increasing the concentration of methanol extract of Aegle marmelos. At 1000ppm concentration of leaf extract the hatching percentage of O. nibilalsis, S. littoralis, C. maculates and T. confusum was 36.85%, 36.50%, 34.08% and 35.24% respectively after 72 hours. At 1000ppm concentration of leaf extract the hatching percentage of O. nibilalsis, S. littoralis, C. maculates and T. confusum was 36.85%, 36.50%, 34.08% and 35.24% respectively after 72 hours. The survival percentage of the larvae of all the four insect pests decreased with concentration of methanol extract and with incubation period. At 1000ppm concentration of methanol extract of Aegle marmelos the larvae of these insect pests could not survive at any incubation time. The findings emphasize the efficacy of A. marmelos leaf extract as fumigant against insect infestations of stored grains and strengthen the possibility of using it as an alternative to synthetic chemicals for preserving stored grains.
