Biology, ecology and control of weevils (Curculionidae: Coleoptera) on Mango Mangnifera indica Linn. from western Maharashtra

REFERENCES Mango Mangifera indica Linnaeus is king of the fruits and has nutritional and medicinal value and widely cultivated in Maharashtra. However, the crop is attached by about 11 species of Weevil (Coleoptera: Curculionidae). The important genera refer to Sternochetus, Myllocerus, Apoderus, Rhynchaenus, Alcidodes, Amblyrrhinus and Camptorrhinus. Sternochetus and Rhynchaenus were found damaging fruits and rest of genera has damaged the tender leaves, buds and shoots of mango. S. mangiferae have been studied with respect to biology, ecology, damage and control. S. mangiferae infested fruits of hybrid varieties of mango. The order of preference shown by the species refer to Neelum > Hapus > Ratnagiri > Deogadh > Totapuri > Indigenous. The pest feed on pulp, and cotyledons in seed and bore the fruit at ripen stage. Control measures suggested S. mangiferae Ploughing and digging fields under mango tree will expose diapousing weevils to natural mortality factors. Dipping fruits into 530C hot water for 1 to 2 hours kill the pest stages in mango. Other weevils were control by spraying 0.2% phosphamidon and 0.03% monocrotophos.
