Beet Armyworm Control in Cabbage, 1985
Insecticide and Acaricide Tests, 1987Abstract This experiment was conducted to evaluate three insecticide treatments for controlling beet armyworm larvae. ‘Greenback YR’ variety cabbage was seeded on 24 Sep into single-row beds with 40 inch centers at the Texas Agricultural Research and Extension Center, Weslaco, TX. Soil type was a Willacy fine sandy loam.

Larvicide for Beet Armyworm, 1988
Insecticide and Acaricide Tests, 1989Abstract Larvae from a resident colony reared on artificial diet were preconditioned on clean chrysanthemum foliage for at least 24 h prior to the bioassay. Fresh foliage was dipped in treatment dilutions and allowed to air dry before presentation to larvae. Each dilution contained Plyac at 4 fl oz/100 gal.

Beet Armyworm Suppression on Celery, 1984
Insecticide and Acaricide Tests, 1985Abstract Celery was transplanted on 4 Aug into 9 inch greenhouse pots. On 24 Aug, when plants were ca. 16 inches in heiglit, 10 third-stage beet armyworm larvae from a laboratory colony were placed on each of 4 plants/application rate, and allowed to acclimate for ca. 1 h.

Armyworm Control on Sugar Beets, 1983
Insecticide and Acaricide Tests, 1984Abstract Plots (0.01 acre) were located on a grower’s field near Nampa, Idaho. Treatments were arranged in a randomized complete block design with four replicates. Sprays were applied on 15 Oct. with a CO2 pressurized backpack sprayer at a rate of 50 gal/acre and 30 lb/in .

Oviposition of Beet Armyworm (Lepidoptera: Noctuidae) on Greenhouse Crops
Environmental Entomology, 1986Distribution of beet armyworm, Spodoptera exigua (Hubner), egg batches was similar in chrysanthemum, tomato, gerbera, and geranium crops grown in a greenhouse. Most eggs were laid on the underside of foliage on leaves within 10 cm of the soil surface. In chrysanthemum, moths deposited more eggs on younger than on older plants.

Cabbage Looper and Beet Armyworm Control in Lettuce, 1978
Insecticide and Acaricide Tests, 1980Abstract Materials were tested for cabbage looper and beet armyworm control on Iceberg lettuce 'Climax' Imperial Valley, CA. The plots were two beds (40 inch double planting), 50 ft long with 4 replicates in a randomized block design. Treatments were applied using a hand sprayer equipped with a CO2 cylinder fitted with 4 nozzles (#8004 ...

Bendiocarb Screening Against Beet Armyworm, 1987
Insecticide and Acaricide Tests, 1988Abstract Test insects were reared on artificial diet in a laboratory colony to third and fourth instars. To assess contact toxicity, larvae were placed in Petri dishes, sprayed with their respective treatment dilutions using a hand-held atomizer, then transferred to individual 1-oz creamer cups containing fresh diet and sealed with paper-

Biochemical mechanisms for metaflumizone resistance in beet armyworm, Spodoptera exigua
Pesticide Biochemistry and Physiology, 2014The metaflumizone, which belongs to the class of voltage-dependent sodium channel blockers, was registered to control Spodoptera exigua on vegetables in China in 2009. The present study revealed S. exigua has developed high resistance to this novel chemistry insecticide shortly after 2-3 years application in Guangdong Province of China.
