The current study was conducted in the organic crop field Mustard is an economically significant crop for farmers in three different blocks in terai region, Kumaun, Uttrakhand. Sowing was done on the first week of November in 2020 and first aphid infestation was seen after one month of sowing. The maximum number of aphid reaches in 2nd week of January 2021. Lipaphis erysimi (aphid) population shows a negative correlation with temperature while humidity is non-significant in all three sites. Coccinella septempuncata (natural enemy) is positively associated with aphid numbers and was first seen after 2 week of aphid infestation.
