“…Increased injury on grape plants nearest to the traps may have resulted, in part, because of a phenomenon known as "trap spillover." Trap spillover can occur when pests arrive in the general vicinity of a trap and rest on vegetation before entering and being captured by the trap (Switzer et al 2009). Switzer et al (2009) found that Japanese beetles often accumulated on soybean plants near pheromone-baited traps rather than entering traps directly.…”

Traps and Trap Placement May Affect Location of Brown Marmorated Stink Bug (Hemiptera: Pentatomidae) and Increase Injury to Tomato Fruits in Home Gardens

The invasive brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), is an important pest of field crops, fruit orchards, commercial vegetables, ornamental plants, and home vegetable gardens. Pheromone-baited traps designed to attract, trap, and kill H. halys are marketed for use in home gardens to reduce damage to plants. To test this assertion, we conducted the following experiment: One group of 15 gardeners placed stink bug traps at the end of a row of tomatoes, Solanum lycopersicum (L.), in their vegetable garden and another group of 14 placed no traps in their garden and served as controls. Gardeners with traps were no more or less likely to have H. halys on tomato plants than those without traps, but the abundance of H. halys on tomato fruits was marginally greater in gardens with traps. However, tomato fruits grown in gardens with traps sustained significantly more injury than tomato fruits grown in gardens without traps. Furthermore, tomato fruits on plants near the trap housed more H. halys than tomato fruits on plants at the end of a row away from the trap. Traps may be useful in identifying gardens where H. halys is likely to be found and ones in which stink bug injury to tomatoes is likely. We found no evidence that stink bug traps protected tomatoes from H. halys, and it appears that the addition of traps to gardens may increase injury to tomato fruits.

“…Second, our results help explain patterns in beetle capture with lure-based traps. Switzer et al (2009) found that females that were caught in the trap or around the trap had lower egg loads than females not attracted to the trap and females from control areas. If these traps are interpreted as "aggregations" by Japanese beetles, the results of our study suggest that this trapping pattern may be explained by the likelihood of females with different egg loads to go to aggregation sites.…”

“…This powerful lure can attract thousands of beetles. However, due to limited trapping efficacy, the spillover onto surrounding host plants is counterproductive, unless traps are placed at some distance from the plants needing protection (Switzer et al 2009). …”

The idea of using species-specific behavior-modifying chemicals for the management of noxious insects in agriculture, horticulture, forestry, stored products, and for insect vectors of diseases has been a driving ambition through five decades of pheromone research. Hundreds of pheromones and other semiochemicals have been discovered that are used to monitor the presence and abundance of insects and to protect plants and animals against insects. The estimated annual production of lures for monitoring and mass trapping is on the order of tens of millions, covering at least 10 million hectares. Insect populations are controlled by air permeation and attract-and-kill techniques on at least 1 million hectares. Here, we review the most important and widespread practical applications. Pheromones are increasingly efficient at low population densities, they do not adversely affect natural enemies, and they can, therefore, bring about a long-term reduction in insect populations that cannot be accomplished with conventional insecticides. A changing climate with higher growing season temperatures and altered rainfall patterns makes control of native and invasive insects an increasingly urgent challenge. Intensified insecticide use will not provide a solution, but pheromones and other semiochemicals instead can be implemented for sustainable area-wide management and will thus improve food security for a growing population. Given the scale of the challenges we face to mitigate the impacts of climate change, the time is right to intensify goal-oriented interdisciplinary research on semiochemicals, involving chemists, entomologists, and plant protection experts, in order to provide the urgently needed, and cost-effective technical solutions for sustainable insect management worldwide.
