ABSTRACT: Abundance of mustard aphid Lipaphis erysimi (Hemiptera: Aphididae) and its relationship with the maximum and minimum temperatures, relative humidity, and predator insects specially lady bird beetle, yellow jacket and syrphid fly were studied on mustard varieties namely BARI Shorisa 13, BARI Shorisa 14, BARI Shorisa 15, BARI Shorisa 16 and BARI Shorisa 17 from November 2018 to February 2019 at Gazipur in Bangladesh. The findings showed that the aphids started to increase their population from 28 November, gradually increasing and reaching its peak on 09 January, and then declining. BARI Shorisa 13 and BARI Shorisa 14 revealed the highest and lowest abundanctes of aphid, respectively. Multiple linear regression analysis showed that weather variables collectively predicted 72.0% to 78.1% incidences of aphid on the mustard varieties. Aphid populations on BARI Shorisa 14 was negatively correlated with the abundance of yellow jacket and positively correlated with the abundance of syrphid fly on that variety. Multiple regression equations showed that the collective effect of the predators ranged from 12.5 to 99.1%, but the equations were insignificant.
