Abstract Field trapping experiments were carried out in Norway to measure attraction of the cherry bark tortrix (CBT) Enarmonia formosana to volatile blends of candidate compounds including acetic acid (AA), linalool oxide pyranoid (LOXP), 2-phenylethanol (PET), pear ester (E,Z)2,4-ethyl decadienoate (PE) and (E)-β-farnesene (BF). The binary blend of AA and LOXP caught the highest number of CBT adults. While addition of PET along with PE did not significantly change the attraction, a sex-dependent decrease of female captures was found when LOXP was replaced by PET/PE. Male attraction to AA/LOXP did not differ when PET/PE were added to the blend or when LOXP was substituted by the same two compounds. A similar attraction to blank traps was recorded for the ternary blend of LOXP/PET/PE, for the binary blend of PET/PE and for LOXP alone, supporting AA as a possible fundamental component of CBT kairomone. In addition, a lower number of bycatches of Hedya nubiferana, Anthophila fabriciana, Synanthedon myopaeformis, Pammene spp. and Pandemis spp. were scored in the AA/LOXP than in any blend including AA/PET/PE. BF was not behaviourally active on CBT in our field experiments. The high attraction of both sexes of CBT to the binary blend of AA/LOXP represents a first step towards the identification of a multicomponent kairomone for this pest. A continuous flight activity of both sexes of CBT was recorded from the end of May until the beginning of August, supporting the hypothesis that CBT is univoltine in Norway. Because larval infestation on tree trunks varies substantially with apple varieties, we encourage the collection of additional data to attempt a correlation between adult catch by AA/LOXP traps and the following larval population.

评估化感化学物质作为樱桃树皮 tortrix Enarmonia formosana（鳞翅目：Tortricidae）的物种特异性引诱剂

摘要 在挪威进行了田间诱捕实验，以测量樱桃树皮 (CBT) Enarmonia formosana 对候选化合物的挥发性混合物的吸引力，包括乙酸 (AA)、芳樟醇氧化吡喃 (LOXP)、2-苯基乙醇 (PET)、梨(E,Z)2,4-癸二烯酸乙酯 (PE) 和 (E)-β-法呢烯 (BF)。AA 和 LOXP 的二元混合物吸引了最多的 CBT 成年人。虽然添加 PET 和 PE 并没有显着改变吸引力，但当 LOXP 被 PET/PE 取代时，发现雌性捕获量的性别依赖性减少。当将 PET/PE 添加到混合物中或当 LOXP 被相同的两种化合物替代时，男性对 AA/LOXP 的吸引力没有差异。对于 LOXP/PET/PE 的三元混合物、PET/PE 的二元混合物和单独的 LOXP，记录了对空白陷阱的类似吸引力，支持 AA 作为 CBT kairomone 可能的基本组成部分。此外，Hedya nubiferana、Anthophila fabriciana、Synanthedon myopaeformis、Pammene spp 的兼捕数量较少。和 Pandemis 属。在 AA/LOXP 中的得分比在包括 AA/PET/PE 在内的任何混合物中得分。在我们的现场实验中，BF 对 CBT 的行为并不活跃。CBT 的两性对 AA/LOXP 的二元混合物的高度吸引力代表了鉴定这种害虫的多组分 kairomone 的第一步。从 5 月底到 8 月初，记录了 CBT 两性的连续飞行活动，支持了 CBT 在挪威是单变的假设。因为树干上的幼虫侵染程度因苹果品种而异，
