Cyclic outbreaks of the beet armyworm, Spodoptera exigua (Hubner) (Lepidoptera, Noctuidae), on cotton have been recognized since at least 1977 (Mitchell, 1979). These outbreaks were thought to be the result of increased adaption to cotton, resistance to many of the registered insecticides and a combination of favorable in-season environmental factors. During the past twenty years, outbreaks on cotton have been noted in 1980, 1981, 1988, 1990 and 1993 (Smith and Freeman, 1994). Following the 1993 outbreak, the first Uniroyal Beet Armyworm Information Exchange Seminar (Point Clear, AL) was held to summarize research and stimulate interest in cooperative projects addressing the problem. One of these projects, a wide-area pheromone trapping program, was initiated in 1994 and continued in 1995. This paper summarizes the results of this program.
