abstract
Studies were conducted at Research Farm of Department of Agricultural Entomology, College of Agriculture, Latur (VNKMV, Parbhani) during kharif-2015 to investigate the effect of weather parameters on the occurrence of sucking insect-pests of sole soybean and soybean intercropped with pigeonpea. During the investigation, Aphis glycines, Empoasca kerri and Thrips were emerged as major sucking insect-pests on late season soybean and soybean intercropped with pigeonpea. A. glycines (14.7 aphids per quadrat), E. kerri (17.8 jassids per quadrat) and Thrips (17 thrips per quadrat) reached its peak population during 35^th, 39^th and 35^th standard meteorological week, respectively on sole soybean. The population of A. glycines infesting sole soybean exhibited a positive correlation with number of rainy days while, negative correlation with rainfall, maximum temperature and afternoon relative humidity. E. kerri population infesting sole soybean indicated a negative correlation with rainfall, maximum temperature and afternoon relative humidity. The population of Thrips infesting sole soybean had a positive correlation with minimum temperature while, negative correlation with rainfall, maximum temperature and afternoon relative humidity. However, on soybean intercropped with pigeonpea peak population of A. glycines (20 aphids per quadrat), E. kerri (16.6 jassids per quadrat) and Thrips (19.6 thrips per quadrat) was recorded during 39^th, 35^th and 35^th standard meteorological week, respectively. A. glycines population infesting soybean intercropped with pigeonpea showed a positive correlation with number of rainy days and minimum temperature while, negative correlation with rainfall, maximum temperature and afternoon relative humidity. The population of E. kerri infesting soybean intercropped with pigeonpea indicated a negative correlation with maximum temperature, beforenoon relative humidity and afternoon relative humidity population of E. kerri. The population of Thrips infesting soybean intercropped with pigeonpea had a positive correlation with minimum temperature.
