The spotted alfalfa aphid and its control in the Yaqui Valley


, : The spotted alfalfa aphid and its control in the Yaqui Valley. Agric, tec, Mex, Mexico, D.F., 9, 18-22

Therioaphis maculata (Buckt.) causes severe injury to lucerne in the Yaqui Valley of Mexico, where it is thought to have been present since about 1954. Populations are highest in January-July, and losses of forage range up to 50 per cent., with a reduction in quality of the remainder. Tests of insecticides against the aphid were carried out in 1959.
