Temperature mediated influence of mycotoxigenic fungi on the life cycle attributes of Callosobruchus maculatus F. in stored chickpea

Environmental factors (biotic and abiotic) are major depletion reasons in granaries. Fungi insect pests act synergistically deterioration of grains storages which results nutritional damage to the stored food becomes unpalatable for consumer. There is a need establish timeline synergistic caused by mycotoxigenic fungi better management. For this purpose, interaction (Aspergillus flavus, Aspergillus niger, Penicillium digitatum Alternaria alternata) with Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae) was studied at different temperatures. Development C. observed on fungus inoculated uninoculated arietinum seeds. In development (Fecundity, larval emergence, pupation rate adult emergence) found more as compared grain. The population decreased increase temperature but high temperatures favours developments. More egg laying 27 °C 33 °C. At tested temperatures, emergence other life attributes. Infestation A. flavus niger also increased alternata infestation were 30 respectively. This study will help measuring control practices pest infestations (chickpea) Pakistan.
