Chemical control of mango aphid, Toxoptera odinae van der Goot.
A field trial was carried out in Karnataka, India, in 1980 to determine the effectiveness of 7 insecticides against Toxoptera odinae (v. d. Goot) on mango. Monocrotophos (Nuvacron), dimethoate (Rogor), demeton-S-methyl (Metasystox) or phosphamidon (Dimecron) at 0.05% were the most effective, resulting in almost 100% control of the pest for up to 7 days after spraying. Malathion and quinalphos (Ekalux) at 0.05% and endosulfan (Thiodan) at 0.07% were less effective. It was concluded that the pest could be controlled effectively and economically by spraying alternately with 0.05% phosphamidon and dimethoate during the flowering period.
