Identification and laboratory behavioral test of the alarm pheromone of Acanthocoris sordidus Thunberg (Hemiptera: Coreidae)
Entomological Research 47 (2), 101-106
Abstract: The winter cherry bug, Acanthocoris sordidus Thunberg (Hemiptera: Coreidae), widely spread in South Korea, Japan and Taiwan, is becoming an economic pest in these regions. Its elevated pest status in pepper plant, Capsicum annuum, is a trigger for eco-friendly management tactics. In order to use its pheromone for pest management, the cuticular components of adult A. sordidus were identified and a behavioral bioassay on the functions of the components was conducted. From the whole-body extracts of male and female A. sordidus, 13 compounds (hexanal, 1-hexanol, 2-hexanol, 3-hexanol, hexanoic acid, hexyl acetate, heptyl acetate, octyl acetate, tetradecane, 2-butyl-2-octenal, hexyl hexanoate and (2α,4α,6ß)-2,4,6-tripentyl-1,3,5-trioxane (hexanal trimer, cis- and trans-forms) were identified. In addition to these, two unidentified compounds, a male-specific and a male-rich compound, were also found. Hexanal provoked clear escaping behavior. 1-Hexanol, hexyl acetate and hexanoic acid evoked weaker behavior than hexanal. We concluded that hexanal worked as an alarm pheromone and could be used as a pushing signal for a control program for A. sordidus.
