Incidence of the bean bug Chauliops fallax Sweet and Schaeffer (Hemiptera: Malcidae) was recorded on soybean and pulses grown during Kharif at five different locations under low and mid hills of Himachal Pradesh during 2016. Its incidence varied from 0.20 to 28.8 bugs per 10 plants on soybean and pulses at different locations. The maximum incidence was recorded at Sundernagar on soybean crop (28.80 bugs/ 10 plants) whereas minimum incidence was observed at Una (0.20 bugs/ 10 plants). Seasonal abundance of the bug was studied on soybean, cowpea and black gram (mash) at Palampur starting from third week of June, 2016 till last week of September, 2016. The bug appeared just after germination of the crops and remained feeding on them up to their maturity or harvesting. Peak population on soybean (188 bugs/ 10 plants) was observed during 1st week of August. Peak population on cowpea (68 bugs/ 10 plants) and mash (40 bugs/ 10 plants) was observed during 2nd week of August. Among weather parameters, rainfall and relative humidity had a significant positive correlation with bug population on the three hosts.
