Guava is an important fruit of India, rich in minerals and vitamin C. Fruit flies are one of the most noxious pest of guava which can cause tremendous loss to farmers due to its infestation. Since it is a well established fact that pesticides cause health hazards and damage the environment, experiments were laid out during the year 2011-12 and 2012-13 for evaluating bio-efficacy of indigenous plant extracts on guava fruit fly Bactrocera correcta (Bezzi) on its emergence and longevity by pupal treatment; as reproductive inhibitor by fruit treatment and effect on maggots of guava fruit fly by sandwich method under the laboratory conditions at departmental of Entomology. The present investigations deal with 10 indigenous plants such as Azadirachta indica, Parthenium histophorum, Norium oleander, Annona squamosa, Cantharanthus roseus, Lantana camera, Pongamia pinnata, Ocimum sanctum, Dhatura stramonium and Apocynum cannabium used as methanol extract as possible management tools to manage population of guava fruit fly B. correcta. As indicated in various experiments; Neem Azadirachta indica possesses strong insecticidal and sterilent activity at higher concentration of 8 per cent followed Lantana camera, Pongamia pinnata, Ocimum sanctum and Dhatura stramonium. The effect of plant extracts as inhibitor of reproductive potential displayed a gradual decrease in fecundity with the increase of concentration. In this trial Neem treatment affected fecundity more than longevity, therefore, use of Azadirachtin based compound in insecticidal baits appeared possible especially when mixed with attractant substances.
