Online published on 15 December, 2016. Abstract Study on seasonal abundance of Spilosoma obliqua Walker (Arctidae: Lepidoptera) on oilseed crops was carried out at Department of Agricultural Entomology, B. A. College of Agriculture, Anand Agricultural University, Anand during July to January 2013–14. Study on seasonal abundance of S. obliqua on various oilseed crops revealed that the pest was active on various crops from 2nd week of July to 4th week of October. The higher activity on castor, groundnut, soybean and sesame was found during 2nd week of August to 2nd week of October. The pest showed significantly positive correlation with wind speed, bright sunshine, maximum and minimum temperature, morning and evening vapour pressure deficit, while significantly negative correlation with morning and evening relative humidity, morning and evening vapour pressure.
