Many small predators such as predaceous thrips, minute pirate bugs, and spiders feed on thrips. Baythroid® XL, a pyrethroid, performs on a broad spectrum of insect pests, with fast knockdown and long residual control. Thrips are tiny, slender, agile insects. When corn plants are stressed for water during long stretches of hot, dry weather, the most damage from corn thrips can occur. All thrips inhabit secluded areas on plants, such as unopened flower and terminal buds, which reduces exposure to insecticide applications. Biology and Control of Thrips on Seedling Cotton Thrips are the smallest of all cotton insect pests with an overall body length of less than one-twelfth of an inch. Table 2. and thrips (Thrips spp.) The boll weevil arrived in the state that year and acreage dropped until the weevil was eradicated in the late 70s and early 80s. The best approach to managing thrips and other cotton insects is preventative control. Also remember that tank mixes to control both weeds and thrips can reduce application costs. Thrips in soybeans are not often noticed, yet they are among the most numerous soybean insect pests. Both immature thrips and adults will feed on leaves. Baythroid XL is a Restricted Use Pesticide. The lifecycle involves about 16 days from egg to mature adult. Grass thrips feed on leaf cells by penetrating leaves and sucking out the cell contents. thrips eggs laid on the plant, eggs hatched, and immature thrips are surviving). Concern about thrips resistance to neonicotinoid insecticides (the active ingredient in Admire Pro and insecticidal seed treatments) has generated lots of questions about managing damage on susceptible cotton. A saturated stand will not grow well and will be more at risk for thrips. Cotton aphid, Aphis gossypii. Development of computer model to project Thrips pressure. Baythroid® XL insecticide, a pyrethroid, performs on a broad spectrum of insect pests, with fast knockdown and long residual control. There are really only two seed treatment options in cotton: neonics and acephate. In-furrow insecticide treatment is recommended in fields with known high infestations of cotton thrips. The soybean seedling stage (VE to V6) presents the most risk from economic damage caused by thrips. Preventive insecticide treatments at planting are used by most growers for early season thrips control. And according to the Mississippi State University Extension and research entomologists, the probability of having a thrips infestation in cotton in most parts of the Mid-South is 100%. Follow IPM guidelines for cotton and always rotate insecticides with different modes of action to effectively manage insecticide resistance in combination with other control practices. Control data provided by Dr. David Kerns (formerly Texas A&M AgriLife Extension Service . All thrips inhabit secluded areas on plants, such as unopened flower and terminal buds, which reduces exposure to insecticide applications. In this case, separate trips over the field should be made. For areas with a history of early-season insect infestations, growers can use Aeris® insecticide/nematicide seed treatment, which offers broad-spectrum protection against thrips as well as cutworms and reniform and root knot nematodes. To improve the efficiency of your monitoring program, combine sampling of thrips with other pests. This is followed by two larval stages, which take six days. And the plant bug isn't that far behind.
