Abstract :

Amrasca kerri Pruthi (Cicadellidae : Hemiptera ) is potential cell sap sucking pest of cowpea Vigna unquiculata (L.) Walp in Kolhapur region of Maharashtra. As a biocontrol agent of A. kerri role of Brumus sp. (Coccinellidae : Colecoptera) has been tested in the field and laboratory conditions (25±1oC, 65–70% RH, 12 hr photoperiod). Brumus sp. is good biocontrol agent of A. kerri. Per day Brumus sp. consumed 4–5 jassids in the laboratory. In the field Brumus sp. was associated with pest with the proportion of increase or decrease of the pest population throughout the persistence of the crop during summer season.
