Beet Armyworm Control in Cabbage, 1985

Insecticide and Acaricide Tests, 1987
Abstract 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, 1989
Abstract 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.

Oviposition of Beet Armyworm (Lepidoptera: Noctuidae) on Greenhouse Crops

Environmental Entomology, 1986
Distribution 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, 1980
Abstract 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 ...

Biochemical mechanisms for metaflumizone resistance in beet armyworm, Spodoptera exigua

Pesticide Biochemistry and Physiology, 2014
The 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.
