Abstract :
Sugarcane plant hopper Pyrilla perpusilla causes vast damage to the crop by sucking cell sap from the leaves. It is the problematic pest in sugarcane fields of north Bihar. The pest is found gregariously on the under surface of the leaves where they suck up plant sap that causes yellowing and eventually drying of leaves. Under low infestation yellow patches appear on the leaves. Photosynthesis is reduced resulting in the reduction of sucrose content. Hoppers secrete a sweet substance called honey dew that coats the leaves and attracts a blackish fungus, which reduces photosynthesis resulting in yield loss. The objective of study is to evaluate pest outbreak in different varieties of sugarcane fields. The various strategies were implied to minimize pest population limited to optimum level to use in place of pre-applied traditional approaches.
