Bottom Line: As of today, it has been found in more than 42 states.Exposure of pheromone-emitting adult males to synthetic C13 greatly reduced pheromone emission.This information should lead to a better understanding of the biology, physiology, and chemical ecology of BMSB, which will help scientists and growers develop more efficient strategies based on natural products to manage BMSB population, therefore, reducing pesticide usage and protecting the crops from BMSB damage.

ABSTRACT

Background: The brown marmorated stink bug (BMSB) is an exotic insect pest that was first recognized in the United States in 2001. As of today, it has been found in more than 42 states. BMSB has a very broad host plant range and damage to crops in mid-Atlantic States has reached a critical level. A reliable and accurate tool for infestation detection and population monitoring is urgently needed to provide better and more timely interventions. Pheromones produced by male BMSB have been previously identified and are currently used in BMSB infestation detection. However, the conditions affecting BMSB production of these pheromones were unknown.

Methodology/principal findings: In this study, we collected headspace volatiles from male BMSB under laboratory conditions, measured the temporal patterns of release of these pheromones, and assayed the attractiveness to conspecifics. In addition to the pheromone components, tridecane (C13) and E-2-decenal (an alarm compound) were observed in headspace collections of males, as well as in females and nymphs. Exposure of pheromone-emitting adult males to synthetic C13 greatly reduced pheromone emission.

Conclusions/significance: This information should lead to a better understanding of the biology, physiology, and chemical ecology of BMSB, which will help scientists and growers develop more efficient strategies based on natural products to manage BMSB population, therefore, reducing pesticide usage and protecting the crops from BMSB damage.

Mentions: Synthetic C13 reduces pheromone emission in single males. Fig 4A is an example of C13 effect on pheromone emission for one male. The arrows indicate the date that C13 was added to aeration jars (20 μL on 10/11/12, 30 μL on 10/17/12). Fig 4B shows the average of single male pheromone emission with the application of 20 μL synthetic C13 added to aeration chambers on Day 0 (n = 10). Synthetic C13 + Aldehyde did not reduce pheromone emission in single males. Fig 5A is an example of the effect of 10:1 C13:Aldehyde (20 μL at each arrow). Fig 5B shows the average single male pheromone emission with the application of 20 μL C13 + Aldehyde on Day 0 (n = 6).
