Title : Succession of insect pests and natural enemies in brinjal in Manipur, North East India with bio-pesticide application

Abstract :

Solanum melongena is one of the most popular vegetables of India and found to be affected by several insect pests which attribute to the low productivity of brinjal. The populations of insect pests and natural enemies on brinjal were surveyed during 2020-21 for studying their succession. The experiments were carried out in a Randomized Block Design (RBD). It was found that the Aleurodicus dispersus, Paracoccus marginatus, Amrasca biguttula biguttula, Aphis gossypii and Leucinodes orbonalis were found to be dominant and abundant in the brinjal ecosystem. Moderate infestation was found during rainy season but heavy infestation was observed from November to January, 2021. The bio pesticide Verticillium lecani, Metarhizium anisopliae and Beauveria bassiana were applied on brinjal grown in fields which later was found to be effective and can prevent the population buildup of insect pest of brinjal ecosystem.
