Onion maggot (Diptera: Anthomyiidae) resistance to chlorpyrifos in New York onion fields.
A larval immersion bioassay was developed to identify susceptibility of onion maggot, Delia antiqua (Meigen) (Diptera: Anthomyiidae), to chlorpyrifos and to determine whether this assay could be used to predict control in onion fields. Laboratory colonies were established from larvae collected in New York onion fields during 2003 and 2004, providing us with test insects to use in bioassays. The...
متن کاملDelaying onion planting to control onion maggot (Diptera: Anthomyiidae): efficacy and underlying mechanisms.
Onion maggot, Delia antiqua (Meigen) (Diptera: Anthomyiidae), is an important pest of onion, Allium cepa L., in northern temperate areas, especially in the Great Lakes region of North America Management of D. antiqua relies on insecticide use at planting, but insecticide resistance can cause control failures that threaten the long-term viability of this strategy. Delaying the time onions are pl...
متن کاملNonwoven fiber barriers for control of cabbage maggot and onion maggot (Diptera: Anthomyiidae).
We investigated the use of nonwoven fiber barriers for control of cabbage maggot, Delia radicum (L.), and onion maggot, D. antiqua (Meigen). The barriers consist of arrangements of minute fibers loosely intertwined in "web" form. Results from a greenhouse experiment showed that manually applied graphite fibers placed at the base of broccoli plants reduced the number of D. radicum eggs by 64-98%...
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 کاملOnion Routing for Resistance to Traffic Analysis
Using encryption on a packet-switched network can hide the content of messages, much like placing the messages inside a physical envelope. However, by itself encryption does not hide who is talking to whom, and how often. Onion Routing is a general purpose infrastructure for private communication over a widely shared network such as the internet or the SIPRNET. It provides anonymous connections...
