Management of the Beet Armyworm (lepidoptera: Noctuidae) in Cotton: Role of Natural Enemies
نویسنده
چکیده
The beet armyworm, Spodoptera exigua (Hubner), has recently become a persistent and explosive pest of cotton in the southeastern United States. It is, however, attacked by a large and diverse complex of beneficial arthropods and pathogens that appear capable of maintaining beet armyworm populations below economically-damaging levels. Disruption of this complex contributes to outbreaks of S. exigua . It can

Combining Exclusion Techniques and Larval Death-rate Analyses to Evaluate Mortality Factors of Spodoptera Exigua (lepidoptera: Noctuidae) in Cotton
By combining pesticide exclusion and cage exclusion techniques, the efficacy of natural enemies in reducing populations of Spodoptera exigua (Hübner), the beet armyworm, larvae was effectively demonstrated. Larval collections added information about parasitism and disease, and when combined with data from insecticide treatments, demonstrated that differences in S. exigua population densities us...
متن کاملField and Laboratory Performance of Novel Insecticides against Armyworms (lepidoptera: Noctuidae)
Beet armyworm, Spodoptera exigua (Hübner), and fall armyworm, Spodoptera frugiperda (J. E. Smith), are occasional pests of cotton, Gossypium hirsutum (L.), and soybean, Glycine max (L.) Merrill. These insects can be difficult to control due to insecticide resistance and larval behavior on plants. The objectives of these studies were to determine the efficacy of selected insecticides against nat...

The beet armyworm, Spodoptera exigua (Hübner), is a sporadic but devastating secondary pest of cotton. Scouting cotton for egg masses is commonly recommended for identifying potential outbreaks and forproper timingof insecticide applications.However, there is disagreement regarding where to look on the plant for beet armyworm eggs. We investigated and quantiÞed placement of egg masses by labora...

The efficacy of transgenic cotton genotypes containing Cry1Ac, Cry1F, and Cry1Ac stacked with Cry1F (WideStrike®, Dow Agrosciences, Indianapolis, IN) were investigated during 2001-2003 against the beet armyworm, Spodoptera exigua (Hübner) (=BAW), and the fall armyworm, Spodoptera frugiperda (J. E. Smith) (=FAW), in laboratory bioassays and small experimental field plots. In all experiments, cot...
