Abstract
Comparative trials on abscission of Acala 4-42 cotton cotyledons by Tetranychus atlanticus McGregor and T. telarius (L.) were conducted in the greenhouse. Abscission time was correlated with amount of feeding injury produced on the lower leaf surface T. atlanticus females caused injury at more than twice the rate caused by T. telarius females. The amount of injury from feeding by either species was directly proportional to 1) the number of mites used, and 2) the amount of feeding time that elapsed. It appears that difference in feeding injury between the 2 species are more quantitative than qualitative in nature. Only female mites caused feeding injury.
