Laboratory bioassays and field tests demonstrated that a Swiss population ofS. multistriatus responded much more strongly to α- than to δ-miltistriatin in combination with 4-methyl-3-heptanol and α-cubebene. High concentrations of brevicomin appeared to replace α-multistriatin in evoking a response byScolytus species, but this effect can be explained by the fact that the brevicomin was contiminated with small amounts of α-multistriatin. Frontalin, another bicyclic ketal, showed no biological activity. Field tests indicated thatS. pygmaeus aggregates to the same attractant mixture asS. multistriatus. S. scolytus also responded preferentially to this mixture, but the relative amounts of α-multistriatin to 4-methyl-3-heptanol do not appear to be as important as forS. multistriatus.
实验室生物测定和现场试验表明，瑞士多纹实蝇种群对α-与δ-米斯梯丁与 4-甲基-3-庚醇和α-荜澄茄烯结合的反应比δ-米斯梯丁更为强烈。高浓度的布雷威菌素似乎可以替代α-多纹实蝇来引发长角象鼻虫属的反应，但这种效果可以解释为布雷威菌素被少量的α-多纹实蝇所污染。另一种双环缩醛，法尼醇，没有表现出生物活性。现场试验表明，小粒象鼻虫聚集到与多纹实蝇相同的引诱混合物中。长角象鼻虫也优先对这种混合物作出反应，但相对于 4-甲基-3-庚醇，α-多纹实蝇的含量似乎不如多纹实蝇那么重要。
