Bio-Insecticidal Efficacy of Aegle Marmelos Against Myzus Persicae

Abstract

Myzus persicae (Green peach aphids) has wide range of distribution in different plant hosts. As a pest it causes adverse effect to crops both directly and indirectly by transmitting different viruses and also by producing honey dew. Myzus persicae transmits almost 100 different viral diseases of plants on thirty different plant families which include some major crops like, sugar cane, tobacco, paddy, citrus, sugar beet etc. Myzus persicae is cosmopolitan in distribution. This insect pest causes damage to wide range of economically important crops and their control is usually dependent upon chemicals, intensive use of which may develop resistance in them. During this experiment botanical pesticide is used as natural control measure and tested its efficacy against Green peach aphids at different concentrations. The plant used is Aegle marmelos. Plant parts such as stem and leaves were used to prepare Boiling and Soxhlet extract.  Each extract of plant was individually tested against the aphids’ nymph which gave maximum mortality of about 97.7% results at the concentration of 500 ppm. The use of this botanical pesticide helps to eradicate the crop pests by an eco-friendly manner.
