Potential Effects of Herbal Preparation of Eucalyptus globulus and Anacardium occidentale on Sustainable control of grubs of Henosepilachna vigintioctopunctata (Fab.) on Solanum melongena Plant

Abstract

Insects cause a lot of damage to plants leading to wilting and drying of leaves, and reducing the chlorophyll content thereby leading to death of plants. The present study was focussed on the serious pest of brinjal (eggplant) namely Henosepilachna vigintioctopunctata. Solvent extracts from Eucalyptus globulus and Anacardium occidentale using methanol and hexane were used for the experiment as herbal preparations. The grubs were collected and reared in the laboratory to identify the mortality rate. The extract from E. globulus and A. occidentale using methanol was found to be more effective in controlling the grubs rather than the extracts with hexane. In comparison it was found that E. globulus has a greater role in the eradication of grubs of H. vigintioctopunctata.
