To study about the seasonal incidence Jassid and Hadda beetle of Brinjal (Solanum melongena L.)

Abstract

The Solanaceae family includes brinjal (Solanum melongena L.), often known as eggplant, aubergine, garden egg, baingan, vankai, etc. It is one of the most significant main vegetables that is widely grown in tropical and temperate regions of the world (during the summer). India is regarded as the origin and diversification center for brinjal. Individually, brinjal leaves and seeds are also used as stimulants and necrotics. The main commercial vegetable crop grown all year round in India is the brinjal. Weather conditions therefore play a significant influence in the biology of any pest because environmental factors affect the number and dispersion of pests. The most important abiotic factor affecting an insect's pace of growth and development is temperature, which is particularly essential because controlling insects as pests requires precise timing. However, relative humidity and rainfall are also significant factors that have a significant impact on an insect species' activity. The relationship between abiotic conditions and pest activity aids in determining when to apply various management strategies to manage insect pests. Therefore, an effort has been made to evaluate the dynamics of Hadda and Jassid populations at various growth stages and the nature of damage they cause.
