Evaluation Of Efficacy Of Formulations Of Plant Prosopis Juliflora Against Callosobruchus Chinensis Linn

Abstract

An investigation was conducted to evaluate the efficacy of extracts obtained from different parts (bark, leaf and fruit) of P.julifora against C.chinensis. A significant mortality of the insect, up to 66.67%, was obtained in some cases. The adult pests were also subjected to smoke of the different plant parts for assessing results in terms of adult mortality. Here also fruit and leaf formulations were able to cause 70% mortality. Similar encouraging results were found when different plant parts were used as egg laying deterrents (reduced to 6 no. /pair as against a normal of 42.33 no. / pair). Some treatments were capable of lengthening the period of insect development by as much as 10 days. Significant results were obtained for managing adult emergence from host grains were in best case scenario it dropped from 93% to 56%.
