Aerial movements of the cotton aphid, Aphis gossypii Glover (Homoptera : Aphididae), and discovery of male morphs in the Texas High Plains Academic Article uri icon

abstract

  • Aerial dispersal of the cotton aphid, Aphis gossypii Glover, was monitored with an Allison-PikeĀ® insect suction trap at the Texas Agricultural Experiment Station, Lubbock, Texas in 1989, 1992, 1993 and 1994. This suction trap collected a single male A. gossypii on 2 December 1992, the first confirmed report of the male form of A. gossypii in the Texas High Plains. A combined total of 13 male morphs were collected by the suction trap and from cotton plants near the trap site. In an effort to establish a method of predicting infestations in cotton, cotton aphid suction trap collections were compared to field densities in a nearby cotton field. Results indicated that suction trap collections during the growing season were not predictive of cotton aphid field population densities. However, numbers of cotton aphids collected by suction trap in November may be predictive of spring field population densities.
