摘要

碳氢化合物在昆虫的生命周期中起着重要作用。它们的组成和浓度可能受到几个因素的影响。碳氢化合物在卵细胞中生物合成，随后被输送到昆虫的角质层，如铃木果蝇（Matsumura）（直翅目：果蝇科）。由于提取程序显著影响所获得的碳氢化合物的类型和数量，我们确定了提取这些化合物的最大量所需的时间与铃木的行为之间的关系。每种碳氢化合物达到稳定状态所需的提取时间不同，在大多数情况下超过一个小时。另一方面，如果需要调查铃木的整个碳氢化合物过程，则需要明显长于一小时的提取时间。通过延长提取时间，首次在铃木中检测到5种额外的碳氢化合物。其中一种，十二烷被证明是排斥D.suzukii。此外，提取3小时后才确定9-五碳烯的最大值，这是引发铃木交配行为的原因。

Effect of solvent extraction time on the hydrocarbon profile of Drosophila suzukii (Diptera: Drosophilidae) and behavioural effects of 9-pentacosene and dodecane

. Hydrocarbons play a major role in the life cycle of insects. Their composition and concentration can be affected by several factors. Hydrocarbons are biosynthesized in oenocytes and subsequently transported to the cuticle of insects, such as Drosophila suzukii (Matsumura) (Diptera: Drosophilidae). As the extraction procedure markedly affects the type and amount of hydrocarbon obtained we determined the association between the time taken to extract the maximum amounts of these compounds and the behaviour of D. suzukii . The required extraction time to reach a steady state is different for each hydrocarbon, which in most cases is more than one hour. On the other hand, if the entire hydrocarbon pro ﬁ le of D. suzukii needs to be investigated, extraction times signi ﬁ cantly longer than one hour were required. By extending the extraction time 5 additional hydrocarbons were detected in D. suzukii for the ﬁ rst time. One of them, dodecane proved to be repulsive to D. suzukii . In addition, it took 3 h of extraction to determine the maximum value of 9-pentacosene, which is responsible for triggering mating behaviour in D. suzukii .

期刊介绍： EJE publishes original articles, reviews and points of view on all aspects of entomology. There are no restrictions on geographic region or taxon (Myriapoda, Chelicerata and terrestrial Crustacea included). Comprehensive studies and comparative/experimental approaches are preferred and the following types of manuscripts will usually be declined: - Descriptive alpha-taxonomic studies unless the paper is markedly comprehensive/revisional taxonomically or regionally, and/or significantly improves our knowledge of comparative morphology, relationships or biogeography of the higher taxon concerned; - Other purely or predominantly descriptive or enumerative papers [such as (ultra)structural and functional details, life tables, host records, distributional records and faunistic surveys, compiled checklists, etc.] unless they are exceptionally comprehensive or concern data or taxa of particular entomological (e.g., phylogenetic) interest; - Papers evaluating the effect of chemicals (including pesticides, plant extracts, attractants or repellents, etc.), irradiation, pathogens, or dealing with other data of predominantly agro-economic impact without general entomological relevance.
