Pheromone mating disruption offers selective management options for key pests

Lobesia mating disruption by pheromone mesofiber dispensers

Lobesia botrana (Lepidoptera: Tortricidae) is a permanently established viticultural insect pest in all vinegrowing countries. According to recent findings, sex pheromones dispensed from electrospun mesofibers serve as environmentally compatible, biodegradable mating disruptants of an innovative type. Their disruptive effects in vineyards last for a minimum of 7 weeks per application, equivalen...

Evaluation of pheromone release from commercial mating disruption dispensers.

Pome fruit growers and crop consultants have expressed concerns about the seasonal release performance of commercial codling moth mating disruption dispenser products. Because of these concerns, we developed a laboratory flow-through volatile collection system (VCS) for measuring the volatile release of the codling moth sex pheromone, codlemone, from commercially available hand-applied dispense...

Mating Disruption of Oriental Beetle with Sprayable Sex Pheromone Formulations

Efficient Management of Fruit Pests by Pheromone Nanogels

Environment-friendly management of fruit flies involving pheromones is useful in reducing the undesirable pest populations responsible for decreasing the yield and the crop quality. A nanogel has been prepared from a pheromone, methyl eugenol (ME) using a low-molecular mass gelator. This was very stable at open ambient conditions and slowed down the evaporation of pheromone significantly. This ...

Female Moth Calling and Flight Behavior Are Altered Hours Following Pheromone Autodetection: Possible Implications for Practical Management with Mating Disruption

Female moths are known to detect their own sex pheromone-a phenomenon called "autodetection". Autodetection has various effects on female moth behavior, including altering natural circadian rhythm of calling behavior, inducing flight, and in some cases causing aggregations of conspecifics. A proposed hypothesis for the possible evolutionary benefits of autodetection is its possible role as a sp...
