Brinjal is cultivated in about 30,000 hectares of land in Bihar spread between 220 - 290 longitude and 840-890 latitude - LECINODES ORBONALIS G. is very serious pest of Brinjal plant. Bihar is divided into three distinct agro-ecological zones showing the various degree of Borer infestations. Higher mean infestation (29%-34%) was observed in North and South Bihar plains having limy-alkaline and black-grey neutral soils respectively where regular intense-cropping pattern exist. However, South Bihar plateau with red-acidic soil coupled with alternate-scattered cropping pattern should lower mean infestation 18.15%. According to topography indirect bearings of infestation of it influences fertility of the soil and cropping pattern of the area.
