A Laboratory Bioassay for Monitoring Resistance in Tarnished Plant Bug Populations to Neonicotinoid Insecticides
A laboratory bioassay was developed for testing tarnished plant bug populations for resistance development to the neonicotinoid insecticides imidacloprid and thiamethoxam. The bioassay allows for the determination of LC50 values by feeding known doses of the insecticides to adult tarnished plant bugs in a honey-water solution. Field populations of plant bugs from several locations in the mid-So...
متن کاملBiological Control of the Tarnished Plant Bug, Lygus
Lygus lineolaris is a pest of many economically important crops. While the species comprising the Peristenus pallipes complex are native parasitoids of L. lineolaris, they do not provide adequate biological control of L. lineolaris. As a result, the European parasitoid, Peristenus digoneutis, was introduced in forage alfalfa. Peristenus digoneutis successfully dispersed from forage alfalfa to s...
متن کاملReproductive Refractoriness in the Western Tarnished Plant Bug (Hemiptera: Miridae)
Adult Lygus hesperus Knight (Hemiptera: Miridae), major crop pests of the southwesternUnitedStates, canmate repeatedlyduring their lives, potentiallyenhancing the lifetimeÞtness ofboth sexes.However, theperiodicityofmating and its regulation in this species is poorlyunderstood. In this study the postmating refractory period for both sexes is described. Males were found to have a median delay of...
متن کاملDevelopment of a plant-based threshold for tarnished plant bug (Hemiptera: Miridae) in cotton.
The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), is an important pest of cotton, Gossypium hirsutum L., in the mid-southern United States. It is exclusively controlled with foliar insecticide applications, and sampling methods and thresholds need to be revisited. The current experiment was designed to establish a plant-based threshold during the flowering period of cotton develo...
متن کاملDiet Selection Exhibited by Juvenile and Adult Lifestages of the Omnivores Western Tarnished Plant Bug, Lygus hesperus and Tarnished Plant Bug, Lygus lineolaris
Lygus hesperus Knight and Lygus lineolaris (Palisot de Beauvois) (Heteroptera: Miridae) are economically important plant bugs on many crops worldwide. However, these omnivores are also facultative predators on a wide variety of insects. This study was conducted to quantify and compare herbivory and carnivory exhibited among different lifestages of these two insect pests. The feeding activity of...
