Abstract

Cephalic extracts of two unrelated species of ants,Leptogenys processionalis andPogonomyrmex rugosus, have been found to contain 2-phenylpropenal and 2-phenyl-2-butenal, while two other species related to the first,L. chinensis andL. kitteli, lacked either.L. kitteli also produced a tetrasubstituted pyrazine found previously only in two New Zealand ants in the genusMesoponera. The chemical reactivity of the phenylalkenals suggests their function in repelling attack by predators.

摘要

已发现两种无亲缘关系的蚂蚁，即行军蚁（Leptogenys processionalis）和多刺蚁（Pogonomyrmex rugosus）的头部提取物中含有 2-苯基丙烯醛和 2-苯基-2-丁烯醛，而另外两种与第一种蚂蚁相关的物种，即中华大头蚁（L. chinensis）和金环胡蜂（L. kitteli）则要么缺乏这种物质，要么都缺乏。金环胡蜂还产生了一种以前只在新西兰的两种中胸蚁属（Mesoponera）蚂蚁中发现的四取代吡嗪。苯丙烯醛的化学反应性表明它们具有抵御捕食者攻击的功能。
