Description

The book on seasonal incidence of safflower aphid Uroleucon compositae was conducted at VNMKV, Parbhani during Rabi 2020-21. Aphid population ranged from 4.1 to 188 aphids per 5 cm apical twig per plant, first appearing in the 51st meteorological week, peaking in the 4th week, and disappearing after the 11th week. Maximum temperature and pan evaporation showed significant negative correlation with aphid population, while other weather factors showed mostly non-significant relationships.Predator studies showed strong biological control potential. Mallada spp. larvae consumed 120.32 aphids during their total grub period, while Coccinella transversalis consumed 490.22 aphids during its entire life cycle.Laboratory bioassay of five insecticides showed LC50 values from 0.003-0.31%. Fipronil 5 SC was most toxic followed by Carbosulfan 25 EC, Profenofos 50 EC, Acephate 75 SP and Dimethoate 30 EC.
