Insecticide Performance Evaluations for Control of Tarnished Plant Bug, Lygus Lineolaris
نویسندگان
چکیده
The tarnished plant bug (TPB), Lygus lineolaris (Palisot de Beauvois), has become known as a midto late-season pest in addition to an early-season pest in recent years with the addition of Bt cotton, completion of the Boll Weevil Eradication Program, and use of lepidopteran-specific insecticides. The expanded prominence of TPB requires continued applied research in the form of insecticide efficacy trials concerning its control.

Effect of Insecticide Regimens on Biological Control of the Tarnished Plant Bug, Lygus lineolaris, by Peristenus spp. in New York State Apple Orchards
To improve biological control of Lygus lineolaris (Palisot de Beauvois) (Hemiptera: Miridae), the European parasitoid Peristenus digoneutis Loan (Hymenoptera: Braconidae) was introduced into the US in the 1980's and has become established in forage alfalfa, strawberries and apples. The objective of this study was to determine how four different insecticide management regimes affected parasitism...
متن کاملCharacterization of eight polymorphic microsatellite markers in the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois)
A partial genomic library of the tarnished plant bug, Lygus lineolaris, enriched for microsatellite sequences was screened to identify marker loci. Eight polymorphic loci suitable for population genetic studies were identified by screening 192 field-collected insects. The observed number of alleles ranged from four to 21 with an average of 12.25 (SE ± 1.94) while the effective number of alleles...
متن کاملExpressed sequenced tags from Lygus lineolaris (Hemiptera: Miridae), the tarnished plant bug.
Expressed sequenced tags (ESTs) were prepared to establish a baseline for molecular genetic studies of the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois). The largest class of identifiable ESTs (15.2%) was from genes involved in cellular metabolic functions, including physiological processes. Twenty-seven ESTs (9.8%) were from genes associated with transcription and translation, in...

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...
