Advances in control of onion thrips (Thysanoptera: Thripidae) in cabbage.
Onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), feeding injury results in discoloration and a rough texture on cabbage, Brassica oleracea capitata (L.), leaves, and damage may occur deep inside the head. It has become a key pest of cabbage in the United States and many other countries. Previous studies have indicated poor control using insecticides. The present study identified ...
متن کاملIsolation of Microsatellite Loci from the Onion Thrips, Thrips tabaci
Thrips tabaci Lindeman (Thysanoptera: Thripidae), a cosmopolitan pest insect, is subdivided into at least three genetic lineages that have different biological characters, such as reproductive mode and resistibility to insecticides. Since the lineages are discriminated only by mitochondrial DNA, there is a possibility of gene flow among lineages at the genomic level. Nine polymorphic microsatel...
متن کاملDeveloping economic thresholds for onion thrips in Honduras
Seasonal abundance and effect on onion yield reduction were studied for onion thrips, Thrips tabaci Lindeman, for two consecutive seasons (dry and rainy) to develop economic thresholds (ET) in Honduras. Overall, thrips populations were highest during the dry season, with average thrips per leaf per day 5.2 times higher than during the rainy season. In the two onion cultivars tested (Granex 429 ...
متن کاملEvaluation of onion cultivars for resistance to onion thrips (Thysanoptera: Thripidae) and Iris yellow spot virus.
Onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), a worldwide pest of onion, Allium cepa L., can reduce onion yield by > 50% and be even more problematic when it transmits Iris yellow spot virus (family Bunyaviridae, genus Tospovirus, IYSV). Because T. tabaci is difficult to control with insecticides and other strategies, field studies on onion, Allium cepa L., resistance to T. ta...
متن کاملImpact of straw mulch on populations of onion thrips (Thysanoptera: Thripidae) in onion.
Development of insecticide resistance in onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), populations in onion (Allium spp.) fields and the incidence of the T. tabaci transmitted Iris yellow spot virus have stimulated interest in evaluating alternative management tactics. Effects of straw mulch applied in commercial onion fields in muck areas of western New York were assessed in ...
