Mating Disruption / SIR Predicting the success of mating disruption

چکیده
Examining the many successes and failures of mating disruption reveals that there is a great deal of variability in the susceptibility of species to this control tactic. For some species, such as redbanded leafroller and oriental fruit moth, treatment with pheromone alone is often sufficient to mitigate crop damage. Other pests, such as the codling moth and certain leafrollers, appear to be more "difficult" to control using only mating disruption. Over the past few years we have been conducting studies to determine the factors that may allow the more resilient species to operate in environments permeated with synthetic pheromone. It appears that there are fundamental differences in the capacities of species to become adapted and/or habituated when exposed to high doses of synthetic pheromone. In addition, pheromones vary considerably with respect to rates of evaporation, dispersion in air, and adsorption onto solid surfaces. Collectively, differences in these physico-chemical properties can have profound effects on the longevity and movement of pheromones in the environment. Finally, it is well known that species differ in their dispersal and reproductive capabilities. We propose that it is these basic differences in the properties of moths and their pheromone that make some species highly susceptible to mating disruption, while others are capable of averting the effects of this control technique.

Optimization of pheromone deployment for effective mating disruption of oriental beetle (Coleoptera: Scarabaeidae) in commercial blueberries.
Cost is a potential limiting factor in the adoption of mating disruption to control oriental beetle, Anomala orientalis (Waterhouse) (Coleoptera: Scarabaeidae). A 3-yr study was conducted in 1-ha blueberry, Vaccinium corymbosum L., plots to test the possibility of lowering cost by reducing the number of point-source dispensers and pheromone [(Z)-7-tetradecen-2-one] concentrations, while maintai...

Hand-applied dispensers are successfully used in mating disruption programs, but cost of labor to apply these dispensers limits their adoption. Creating hand-applied dispensers that release larger amounts of pheromone and that can be applied at lower densities per hectare could reduce the cost of mating disruption and increase its use. The effect of reducing the number of point sources per hect...

SPLAT-OrB reveals competitive attraction as a mechanism of mating disruption in oriental beetle (Coleoptera: Scarabaeidae).
This study compared the efficacy of SPLAT-OrB, a new pheromone formulation for oriental beetle mating disruption that can be mechanically applied, with hand-applied plastic dispensers in commercial blueberry fields. Both formulations were tested at 2.5 and 5 g of the major sex pheromone component (Z)-7-tetradecen-2-one per hectare, and evaluated by measuring trap shut-down, mating success of ca...
متن کاملSimulation of mating disruption and mass trapping with competitive attraction and camouflage.
Simulation models of mass trapping and mating disruption were developed based on correlated random walks (CRW) of flying male moths searching for females. Males encountered pheromone plumes, transformed into a circular probability surface represented as an effective attraction radius (EAR), from females and from dispensers with or without traps. In simulations, parameters of dispenser EAR and d...
