Abstract

The enhancement of natural predators through habitat manipulation and increasing vegetational diversity can improve herbivore control. Aphids drew attention as they are serious phytosaccivorous pests and a threat against crop plants. Members of Family Chrysopidae (Neuroptera: Insecta) are proven biological control agents against aphids. Natural predators can bring down pesticide use against pest in a proper IPM (Integrated Pest Management) strategy. For this, identification of the existing pest, their natural predators and the pest host plant are necessary. This study deals with the field survey for aphids, aphid host plant and Chrysopidae species associated with aphids. This investigation may provide some essential basic information of occurrence aphids, their crop plant association and aphidophagous Chrysopidae. This may help to formulate an integrated pest management (IPM) strategy against aphid pest of crop plants in near future.
