This study is on the host range and geographical distribution of Andrallus spinidens (F.) in the agroecosystems of Kumaon region of Uttarakhand. Predatory bug was surveyed in selected locations from all six districts in Kumaon region of Uttarakhand from March 2018 to February 2019. The bug occurs invariably in all the locations on wheat, soybean, maize, pigeonpea, gram, rice, beans and cowpea crops and associated with lepidopteran pests. The preferred preys were found to be the instars of larvae of Mythimna separata and Helicoverpa armigera in wheat, Spodoptera litura in soybean and cabbage, Cnaphalocrosis medinalis in rice, Maruca vitrata and H. armigera in pigeonpea, S. litura and M. vitrata in beans, H. armigera in okra and gram, and Chilo partellus on maize.
