Field trials were conducted at Agricultural Research Station, Amadalavalasa for three consecutive years during Kharif 2015-16, 2016-17and 2017-18 to evaluate the eco-friendly insecticides against sucking insect pests viz., Aphids, Aphis gossypii (Glover); leafhoppers, Bemisiaaci Genn. and mealybug, Phenacoccus solenopsis Tinsley in mesta, Hibiscus sabdariffa L (Roselle). Imidacloprid 600 FS@5ml per kg seed (1part chemical + 1part water) was effective against sucking pests up to 40 days after sowing. Among the treatments, profenophos 50EC@2ml/l (standard check) was most effective against Mesta pests with higher fibre yield. Among the botanical and microbial insecticides, azadiractin (neem oil) (1500ppm) @5ml/l was found effective against sucking pests and recorded higher fibre yield.Amrasca biguttula biguttula (Ishida); whiteflies, Bemisia tabaci Genn. and mealybug, Phenacoccus solenopsis Tinsley in mesta, Hibiscus sabdariffa L (Roselle).
