Development 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 کاملA 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 کاملDistribution of the Tarnished Plant Bug (Heteroptera: Miridae) Within Cotton Plants
The within-plant distribution of the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), in cotton, Gossypium hirsutum L., was determined during June through the 1st week in August in 1992 and 1993 at Stoneville, MS. Locations of adults and nymphs in cotton were determined weekly using visual searches of whole plants or plant sections (mainstem terminals, upper and lower plant halves b...
متن کاملComparison of direct and indirect sampling methods for tarnished plant bug (Hemiptera: Miridae) in flowering cotton.
A complex of hemipterans, especially the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois) (Hemiptera: Miridae), has become a major target of insecticides in flowering cotton, Gossypium hirsutum L., in the mid-southern United States. Sampling protocols for this complex during this period of cotton development are poorly established, resulting in uncertainty about when infestations war...
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...
