Ecology and Control of Brinjal insect pests from Kolhapur region, India

ABSTRACT

Brinjal Solanum melongela L. is an important vegetable crop of subtropics and tropic with fuel, nutritional and ayurvedic medicinal value. In India it is cultivated in almost all states. Therefore, ecology and control of insect pests have been studied from Kolhapur region of India. A total of 12 species of insect pests, namely Leucidonus orbonalis Guen, Euzophera perticella Rag., Epilachna vigintioctopunctata (Fab.), Urentius sentis Diast., Amrasca bigutulla biguttula Dist., Bemisia tabaci Genn., Aleurodicus dispursus (Rus.), Lipaphis erysimi Kalt., Aspidoitus destructor Sign., Aonidiella auranti (Maskell), Thrips palmi Karny and Ants have been recorded damaging Brinjal crop. Out of which L. orbonalis, A. bigutulla bigutulla, A. dispersus, A. destructor, L. erysimi and Ants were found throughout the year. Natural enemies, host plants, life cycle and control measures are suggested in the paper. 0.1% carbaryl or Azadirachtin or 0.05% malathion were found effective. Trichogramma chilonis 1 to 1.5 lakh/ha was found effective for lepidopteran pests as ecofriendly control.   

Key words :   Brinjal, insect-pests, ecology, natural enemies, control.
