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 کاملPyrethroid-resistant onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), infesting persimmon fruit
A total of 53 strains of onion thrips, Thrips tabaci Lindeman, were established, of which 14 strains were collected from persimmon fruit and 39 strains from a vetch weed, Vicia angustifolia, in commercial persimmon orchards in Wakayama Prefecture. Susceptibility to insecticides was evaluated by the Petri dish-spraying tower method. Pyrethroid-resistant strains and pyrethroid-susceptible strains...
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 کاملOnion Thrips (Thysanoptera: Thripidae) Biology, Ecology, and Management in Onion Production Systems
Onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), is a well-known onion pest worldwide. Onion thrips cause both direct and indirect damage to onion by feeding and ovipositing on leaves that may cause green onions (scallions) to be unmarketable and dry bulb onion size to be reduced. Onion thrips can also transmit several plant pathogens that reduce onion bulb size and quality. One ...
