Abstract : In Bangalore, India, 13 insecticides were tested in 1977-78 and 1978-79 in 2 field experiments for the control of Chlumetia transversa Wlk., a serious pest of mango (especially seedlings and young trees) that eats developing leaves and tunnels into the midrib and terminal shoots. All the insecticides tested except nicotine sulfate were at least moderately effective. The synthetic pyrethroids fenvalerate (at 0.01 and 0.02%) and permethrin (at 0.02%) gave effective control but were tested only in the second study year. Other compounds giving consistently good reduction of Chlumetia populations in both years were carbaryl at 0.02% and monocrotophos, quinalphos and phenthoate all at 0.05; these insecticides, together with the pyrethroids, are recommended for application at intervals of 3 weeks for the practical control of C. transversa.ADDITIONAL ABSTRACT:In trials at Bangalore mango shoot borer could be controlled with carbaryl (0.2%), dichlorvos (0.1%), endosulfan (0.07%), fenvalerate (0.01 and 0.02%), permethrin (0.01 and 0.02%), quinalphos, monocrotophos, chlorpyrifos, methamidophos, phenthoate, acephate and parathion-methyl (the last seven at 0.05%). The best results were obtained with fenvalerate, permethrin, carbaryl, monocrotophos, phenthoate and quinalphos. Sprays at intervals of 3 weeks are recommended.
