The response of the two most abundant cockchafer species in central Europe, Melolontha hippocastani and M. melolontha, towards phenol, mixtures of phenol with the leaf alcohol (Z)-3-hexen-1-ol and the known cockchafer pheromones, 1,4-benzoquinone (M. hippocastani) and toluquinone (M. melolontha), was investigated in the field. During the swarming period at dusk, phenol attracted males of both species, and enhanced the known attraction of cockchafer males towards (Z)-3-hexen-1-ol. A mixture of phenol plus (Z)-3-hexen-1-ol was less attractive for M. hippocastani males than a mixture of (Z)-3-hexen-1-ol plus 1,4-benzoquinone, whereas phenol plus (Z)-3-hexen-1-ol attracted as many M. melolontha males as a mixture of (Z)-3-hexen-1-ol plus toluquinone. In both species three component mixtures containing phenol, (Z)-3-hexen-1-ol, and the respective benzoquinone did not capture more males than two component mixtures consisting of only (Z)-3-hexen-1-ol and the benzoquinone. A possible role of phenol as another cockchafer sex pheromone component is discussed.
在野外研究了中欧两种数量最多的金龟子物种，即马栗鳃金龟（Melolontha hippocastani）和黄褐鳃金龟（M. melolontha）对苯酚、苯酚与叶醇（Z）-3-己烯-1-醇的混合物以及已知的金龟子信息素，即1,4-苯醌（马栗鳃金龟）和甲苯醌（黄褐鳃金龟）的反应。在黄昏的群聚期，苯酚吸引了两种物种的雄性，并且增强了已知的金龟子雄性对（Z）-3-己烯-1-醇的吸引力。对于马栗鳃金龟雄性来说，苯酚加（Z）-3-己烯-1-醇的混合物不如（Z）-3-己烯-1-醇加1,4-苯醌的混合物有吸引力，而苯酚加（Z）-3-己烯-1-醇吸引的黄褐鳃金龟雄性数量与（Z）-3-己烯-1-醇加甲苯醌的混合物相同。在这两个物种中，含有苯酚、（Z）-3-己烯-1-醇和各自苯醌的三元混合物捕获的雄性数量并不比仅由（Z）-3-己烯-1-醇和苯醌组成的二元混合物多。本文讨论了苯酚作为另一种金龟子性信息素成分的可能作用。
