Abstract :

A survey for occurrence and spread of leaf and plant hoppers in rice crop during entire growing season was made in farmer’s field and Government Farms of Rewa district of Madhya Pradesh for two consecutive years. Frequency of out eak and population build up of white backed plant hoppers (WBPH) and green leaf hoppers (GLH) were recorded and their correlations were worked out with the prevailing weather conditions. Results revealed that WBPH and GLH were the regular pests in rice, but infestation of former was more serious than later. Though infestation of both hoppers was seen during entire growth span of rice, former was severe pest during early growth phase of crop and later at mid–growth phase. Both pests had shown their strong negative relationships with maximum and minimum temperature and sunshine hours. Thus, forecasting modules are also suggested in this paper to decide timely and effective management of these pests in rice.
