在蚁蚜互惠关系中，蚂蚁攻击和排斥蚜虫的天敌。然而，幼虫的绿色草蛉，Mallada desjardinsi，捕食豇豆蚜虫，Aphis craccivora，没有排除蚜虫倾向的蚂蚁。草蛉幼虫通过背上携带蚜虫尸体来保护自己不受蚂蚁的伤害。在这里，我们测试了蚜虫尸体的表皮碳氢化合物（CHCs）是否会影响蚜虫抚育蚂蚁的侵略性。用正己烷洗涤蚜虫尸体以除去脂质。草蛉幼虫与洗蚜虫尸体更频繁地比那些未经处理的蚜虫尸体蚜虫倾向的蚂蚁攻击。我们测量的侵略性蚜虫倾向的蚂蚁草蛉幼虫，无论是携带一块棉花（假蚜虫尸体）处理的CHCs从蚜虫或草蛉幼虫，或携带蚜虫尸体。蚂蚁对携带蚜虫或蚜虫尸体CHCs的草蛉幼虫的攻击率低于对携带同种CHCs的草蛉幼虫的攻击率。通过气相色谱/质谱分析表明，蚜虫和蚜虫尸体之间的CHCs相似。这些结果表明，蚜虫尸体上的草蛉幼虫的功能，通过化学伪装，以限制攻击蚜虫倾向的蚂蚁。
Ants attack and exclude natural enemies of aphids in ant–aphid mutualisms. However, larvae of the green lacewing,Mallada desjardinsi, prey on the cowpea aphid,Aphis craccivora, without exclusion by aphid-tending ants. Lacewing larvae are protected from ants by carrying aphid carcasses on their backs. Here, we tested whether cuticular hydrocarbons (CHCs) of aphid carcasses affected the aggressiveness of aphid-tending ants. Aphid carcasses were washed withn-hexane to remove lipids. Lacewing larvae with washed aphid carcasses were attacked by aphid-tending ants more frequently than those with untreated aphid carcasses. We measured the aggressiveness of aphid-tending ants to lacewing larvae that were either carrying a piece of cotton wool (a dummy aphid carcass) treated with CHCs from aphids or lacewing larvae, or carrying aphid carcasses. The rates of attack by ants on lacewing larvae carrying CHCs of aphids or aphid carcasses were lower than that of attack on lacewing larvae with conspecific CHCs. Chemical analysis by gas chromatography/mass spectrometry showed similarity of CHCs between aphids and aphid carcasses. These results suggest that aphid carcasses on the backs of lacewing larvae function via chemical camouflage to limit attacks by aphid-tending ants.
