Abstract
Helicoverpa armigera is the most destructive pest of pigeonpea and high infestation level of this pest
causes severe yield losses. The excessive use of synthetic pesticides increase the total cost of operation
and also affect the health of human beings adversely. In spite of these, the use of botanicals pesticides are
less expensive, safe and eco-friendly. In this study, the aqueous custard apple seed extract with five
concentrations (20 mg/ml, 30 mg/ml, 40mg/ml, 50mg/ml and 60mg/ml) were prepared and the efficacy
of test solutions were evaluated against Helicoverpa armigera larvae under laboratory condition. The
lethal concentration LD50 and LC90 of the aqueous custard apple seed extract was found to be 53.24
mg/ml and 107.52 mg/ml, respectively. The results showed that the test solution provides effective
control of Helicoverpa armigera larval and can be used as botanical insecticide.
