Screening, Identification and Activity of Ant Repellant Compounds from Herbal Plants Extracts– A Biological Approach

摘要

Ants are the most dominant group of social insects belonging to order Hymenoptera of class Insecta. Ants can contaminate anddestroy some agricultural products and stored foods. High cost of chemical insecticides leads to search for an alternative source forthe above pest management. The use of toxic chemicals as pesticides to control insects and other pestiferous organism has drawnpublic concern due to environmental and health implications hence the need for alternative techniques of integrated pestmanagement is the need of the hour. Hence the present experiment is carried out to study the phytochemical analysis ofCoriandrum sativum, Ocimum basilicum and Cymbopogan citrates. We found positive results for the presence of phytochemicalcomponents and bioactive compounds by GC-MS analysis. Later we tested these extracts for ant repellant activities in the field atdifferent concentration. From the experiment it was observed that a minimum concentration of the plant extract had maximum antrepellency activity.
