Cotton, Gossypium hirsutum (L.), plants expressing insecticidal crystal (Cry) proteins of Bacillus thuringiensis (Bt) Berliner are planted on significant acreage across the southern region of the United States. Fall armyworm, Spodoptera frugiperda (J. E. Smith), can be a significant cotton pest in some years, but this species has not been a primary target of Bt cotton technologies. The objecti ...

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 n ...

Utilization of stink bug, E. furcellata for controlling beet army worm, Spodoptera exigua Hubner in asparagus was carried out with 3 experiments: firstly, biological studies of stink bug, secondly, the determination of optimum release rate for controlling beet armyworm and thirdly, test on the optimum release rate for controlling beet armyworm in larger scale in farmer's fields. These experime ...

The fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is an economically important pest of sorghum, Sorghum bicolor (L.) Moench. However, resistance to fall armyworm in sweet sorghum has not been extensively studied. A collection of primarily sweet sorghum accessions were evaluated in the field for natural fall armyworm infestation. Fall armyworm damage ratings ranged ...

Field corn, Zea mays L., plants expressing Cry1Ab and Cry1F insecticidal crystal (Cry) proteins of Bacillus thuringiensis (Bt) Berliner are planted on considerable acreage across the Southern region of the United States. The fall armyworm, Spodoptera frugiperda (J.E. Smith), is an economically important pest during the mid-to-late season on non-Bt and some commercial Bt corn hybrids. The objec ...

Cotton, Gossypium hirsutum L., plants expressing Cry1Ac and Cry1F insecticidal crystal proteins of Bacillus thuringiensis Berliner (Bt) were evaluated against selected lepidopteran pests including fall armyworm, Spodoptera frugiperda (J. E. Smith), beet army worm, Spodoptera exigua (Hübner), and soybean looper, Pseudoplusia includens (Walker). Studies were conducted in a range of environments, ...

Fall armyworm, Spodoptera frugiperda (J. E. Smith), colonies were compared to determine whether development on Bt corn or Bt cotton impacted survival and damage potential of subsequent generations on Bt or non-Bt cotton. Late instars of fall armyworm were collected from Bt and non-Bt sweet corn to establish two separate colonies. Two-day old and 5-day old F1 larva(e) from each colony were conf ...

Efficacy of maize, Zea mays L., hybrids and cotton, Gossypium hirsutum (L.), varieties expressing Cry1F insecticidal crystal protein of Bacillus thuringiensis (Bt) var. aizawai Berliner (transformation event TC1507 in corn and event DAS-24236-5 in cotton) was evaluated for control of fall armyworm, Spodoptera frugiperda (J.E. Smith). Control of natural and artificial fall armyworm infestations ...

In two plantings of grain sorghum, Sorghum bicolor (L.) Moench, we investigated the impact of whorl injury by natural infestations of fall armyworm. Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), on subsequent panicle development and infestation. We also examined plant response to panicle infestation by corn earworm, Heliothis zea (Boddie) (Lepidoptera: Noctuidae). Treatments we ...

The Welsh onion beet armyworm, Spodoptera exigua (Huner), has attacked Welsh onion and is now the most important pest of Welsh onion in southwestern Korea. The beet armyworm has a wide host range, occurring as a serious pest of vegetable and fields. The relatively high abundance of beet armyworm has stimulated frequent application of insecticides to foliage. Insecticide resistance is a major p ...
