摘要

摘要本文研究了梨树木虱(Cacopsylla pyricola, Förster)的性吸引过程中化学信号的作用，评价了夏季雄性和雌性木虱对雌雄产生的挥发性化学物质的反应。雄木虱被活雌木虱的气味和雌木虱的戊烷提取物所吸引。雌虫的提取物对雄虫的吸引力与活雌虫一样大，这表明雌虫产生的对雄虫有吸引力的挥发性化学物质可能通过用戊烷提取雌虫来分离。雌性不会被来自活体雌性的气味所吸引，并且倾向于避免来自雌性提取物的气味。此外，夏虫雄性和雌性不会被雄性产生的气味吸引或排斥，这些气味来自雄性的活雄虫或雄性的提取物。对雄性夏型pyricola的嗅觉测定结果与早期对该物种冬型形态的研究结果一致。

Response of Summerform Pear Psylla (Hemiptera: Psyllidae) to Male- and Female-Produced Odors

Abstract We examined the role of chemical signals in sex attraction of pear psylla, Cacopsylla pyricola (Förster), assessing the response of summerform male and female psyllids to male- and female-produced volatile chemicals. Male psyllids were attracted to odors from live females and pentane extracts of females. Extracts of females were as attractive to males as live females, suggesting that the female-produced volatile chemicals responsible for male attraction might be isolated by extracting females with pentane. Females were not attracted to odorants from live females and tended to avoid odorants from extracts of females. Furthermore, summerform males and females were not attracted or repelled by male-produced odorants from live males or extracts of males. Results of olfactometer assays using male summerform C. pyricola are consistent with results from earlier studies with the winterform morphotype of this species.

期刊介绍： French translation follows/le français suit Published since 1868, this peer-reviewed bimonthly publication is the official journal of the Entomological Society of Canada. Available via the internet and with hardcopy distribution to 55 countries, its research papers and notes are relevant to entomologists and other biologists around the world. In addition to being a venue for topical reviews and forum discussion, The Canadian Entomologist publishes current research in all facets of entomology, including systematics and morphology, molecular and developmental biology, ecology and behaviour, biodiversity and evolution, insect management, entomological techniques, and other relevant subject areas. Contributions are published in English or French. Authors will not pay page charges, and will experience fast, high quality reviews of their papers.Publiée depuis 1868, cette publication bimestrielle avec comité de lecture est la revue officielle de la Société d’entomologie du Canada.
