Onion thrips colonization of onion fields bordering crop and noncrop habitats in muck cropping systems
Onion thrips, Thrips tabaci Lindeman, colonization of onion fields may be influenced by bordering crop and non-crop habitats. Identifying habitats adjacent to onion fields associated with high T. tabaci infestations would be valuable for improving scouting efforts and management decisions. A 3-year study examined adult T. tabaci colonization patterns within onion fields early (June through earl...
متن کاملPatterns of insecticide resistance in onion thrips (Thysanoptera: Thripidae) in onion fields in New York.
To develop an insecticide resistance management program for onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), on onions (Allium spp.), we surveyed populations in commercial onion fields in New York and evaluated their susceptibility to the two most widely used classes of insecticides plus two new insecticides during 2003-2005. All insecticide evaluations were conducted using the T...
متن کاملPerformance of novel insecticide seed treatments for managing onion maggot (Diptera: Anthomyiidae) in onion fields
Management of onion maggot, Delia antiqua (Meigen), in onion requires the use of an insecticide applied at planting. Insecticide resistance and a dearth of available products have stimulated an effort to identify new insecticides for onion maggot control, especially chemistries that can be delivered as seed treatments. Onion seeds film-coated with fipronil, spinosad, clothianidin or thiamethoxa...
متن کاملRegional and Temporal Variation in Susceptibility to λ- Cyhalothrin in Onion Thrips, Thrips tabaci (Thysanoptera: Thripidae), in Onion Fields in New York
Populations of onion thrips, Thrips tabaci Lindeman, from commercial onion Þelds in New York were evaluated for their susceptibility to the commonly used pyrethroid, -cyhalothrin (Warrior T), using a novel system called the Thrips Insecticide Bioassay System (TIBS). To use TIBS, thrips are collecteddirectly from theplant into an insecticide-treated 0.5-mlmicrocentrifuge tube that has a ßexible ...
متن کاملEvaluation of sampling methodology for determining the population dynamics of onion thrips (Thysanoptera: Thripidae) in Ontario onion fields.
Onion thrips, Thrips tabaci Lindeman, are an economic pest of alliums worldwide. In Ontario onion-growing regions, seasonal abundance and population trends of onion thrips are not well known. The objectives of this research were to investigate onion thrips population dynamics by using both white sticky traps and plant counts, to gain insight into flight height, and to determine the genus and se...
