The spiraling whitefly Aleurodicus dispersus Russell was found infesting brinjal in Imphal, Manipur during October 2020 and January 2021, with lifestages getting completed on leaves. The spiraling nature was also found with heavily infested leaves getting crinkled before drying out. The honey dew and black sooty moulds symptoms were also observed. Moderate infestation was found during rainy season but it was heavy during November to December. The biopesticide Verticillium lecanii was found to be effective with incidence and the number of spirals observed to be reduced within seven days.

Abstract


The spiraling whitefly Aleurodicus dispersus Russell was found infesting brinjal in Imphal, Manipur during October 2020 and January 2021, with lifestages getting completed on leaves. The spiraling nature was also found with heavily infested leaves getting crinkled before drying out. The honey dew and black sooty moulds symptoms were also observed. Moderate infestation was found during rainy season but it was heavy during November to December. The biopesticide Verticillium lecanii was found to be effective with incidence and the number of spirals observed to be reduced within seven days.
