Abstract

Insects are a major constraint for cowpea. Bio-pesticides are an alternative to chemical insecticides. Study was conducted in Pabré on two oils. Objective is to increase yields through using of oils. Specifically, aim is to determine most effective oil and to determine most effective concentrations. Experimental design is a four-repeat Fisher block with ten elementary plots. Four concentrations per oil were applied with an absolute control and a reference control. Phytosanitary treatments were applied on days 40, 47, 54 and 61 respectively. Data collection was done twice a week from flowering to maturity of cowpea. Results showed that cold extracted oil was most effective against thrips. 5% concentrations of both oils provided good pod

protection against M. vitrata. 1.25% concentration resulted in the best flower, pod and yield production. Cold and hot extracted oil is clearly an alternative method of insect control in Burkina Faso.
