The present research on “Estimate the yield losses due to pink bollworm, Pectinophora gossypiella (Saunders) infesting Bt cotton” was carried out at Village: Daliya, Ta. Gondal, Dist. Rajkot during Kharif, 2020-21. The results of experiment were revealed that the seed cotton yield of 2304.27 kg/ha were recorded from protected plots, while the seed cotton yield of 1478.73 kg/ha were recorded from unprotected plots. However, By providing protection with effective pesticides against pink bollworm 825.54 kg/ha yield loss can be saved and 35.83 per cent avoidable yield loss was recorded in protected plots over unprotected plots during kharif, 2020-21.
