Abstract

Guava is an important commercial fruit crop of tropical and subtropical regions of India. It is a very good source of pectin, calcium, phosphors and vitamin C. This fruit is infested by a number of insect pests of which Bactrocera dorsalis Hendel, formerly known as Dacus dorsalis Hendel and commonly called oriental fruit fly is major pest in Bihar, India. Present investigation was carried out to study the insecticidal control of Bactrocera dorsalis on guava in Mehsi of East Champaran district of Bihar. The efficacy of seven insecticides against the fruit fly was studied in guava orchards and observed that minimum infestation was found in treated trees by Rogar and malathian followed by carbaryl. These insecticides were highly significant (at 0.001%).
