Behavioural response of the invasive Halyomorpha halys (Hemiptera: Pentatomidae) to host plant stimuli augmented with semiochemicals in the field

摘要

1 Although much work has focused on understanding how the invasive brown marmorated stink bug, or Halyomorpha halys, responds to pheromonal stimuli, very little research has explored the response of H. halys to plant volatiles and other host stimuli. The present study aimed to determine (i) whether more acceptable, less acceptable or unacceptable host plants augmented with plant volatile mixes and/or pheromone can enhance the retention capacity of plants for H. halys in the field and (ii) whether plant volatiles [apple, peach or green leaf volatile (GLV) mixtures] can increase attraction to pheromone-baited pyramid traps.
