The efficacy of mating disruption by using Isomate-M 100 pheromone dispensers and two formulations of microencapsulated sprayable pheromone for management of oriental fruit moth, Grapholita molesta (Busck), was compared with conventional insecticides in large plot studies in Henderson County, North Carolina, in 2000 and 2001. In addition, experiments were conducted in small and large plots to t...

We tested different pheromone-baited traps for surveying winter moth, Operophtera brumata (L.) (Lepidoptera: Geometridae), populations in eastern North America. We compared male catch at Pherocon 1C sticky traps with various large capacity traps and showed that Universal Moth traps with white bottoms caught more winter moths than any other trap type. We ran the experiment on Cape Cod, MA, where...

Traps that use ultraviolet light as an attractant for flies are widely used in urban situations. To determine the differences in trap efficacy from design and lighting, pairs of traps were compared under laboratory conditions. Comparisons were made between traps with open fronts and with traps with restricted open fronts, black light bulbs, and black light blue bulbs, and glue boards with and w...

Aerial traps, using combinations of color and attractive lures, are a critical tool for detecting and managing insect pest populations. Yet, despite improvements in trap efficacy, collection of nontarget species ("bycatch") plagues many insect pest surveys. Bycatch can influence survey effectiveness by reducing the available space for target species and increasing trap screening time, especiall...

The dogwood borer, Synanthedon scitula (Harris) (Lepidoptera: Sesiidae), is a serious wood-boring pest of apple in eastern North America. The recent identification of its sex pheromone and systematic documentation of the effect of a potent behavioral antagonist affords the opportunity to develop pheromone-based management strategies for this important pest. Here we evaluated the potential of ph...

The functions of the two synergistic pheromone components, (4s)-cis-verbenol (cV) and 2-methyl-3-buten-2-01 (MB), and the role of ipsdienol in the attraction of Ips typographus (L.) (Scolytidae) to pheromone sources were studied in the field. Absolute and relative beetle catches were compared between several traps placed at and nearby a central pheromone source: a pipe trap containing the sourc...

Research was conducted to evaluate various pink bollworm pheromone dispensers; the Conrel hollow fiber dispenser, gossyplure treated rubber tubing dispensers utilizing either a hexane or methylene chloride solvent, aged dispensers, and dispensers treated with aged pheromone<, Although results varied depending on the time of year, the Conrel dispenser was generally least effective. The two solve...

The efficacy of two trap designs (Pherocon 1C "wing" trap versus Pherocon VI "delta" trap) and two pheromone blends for monitoring obliquebanded leafroller, Choristoneura rosaceana (Harris), was evaluated in Minnesota apple orchards during the 2001 and 2002 field seasons. Two distinct flight periods of C. rosaceana were recorded yearly in Minnesota. Overwintered C. rosaceana larvae resumed acti...

1. The pink bollworm moth Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae) is one of the most destructive pests in agriculture. An ongoing eradication program using a combination of sex pheromone monitoring and mating disruption, irradiated sterile moth releases, genetically modified Bt cotton and local insecticide applications have all but exterminated the pink bollworm from the ...
