Linepithema humile reveals an additional pattern of qualitative differences. Reproductive queens up-regulate the synthesis of hydrocarbons of intermediate chain length (de Biseau et al., 2004). In workers, additional components in the short- and long-chain areas (13-methylpentacosane and di- and trimethyl-branched alkanes with chain lengths of 33 to 37) are present as well. Linepithema also produces large colonies, and workers are sterile.

The Argentine ant Linepithema humile which has invaded Australia and Mediterranean Europe produces a macrolide evidently made from a fatty acid where synthesis begins with 2-methylbutyric acid (Figure 3.39). The Dufour glands of halictine and coUetine bees frequently contain mixtures containing macrocyclic lactones. Colletes bees, for example.

In 1949 Pavan isolated the substance he called iridomyrmecin from the Argentine ant Iridomyrmex humilis (now Linepithema humile). Iridomyrmecin, dolichodial and other monoterpenes with a methylcyclopen-tanoid structure are called iridoids (Figure 6.12). They act as defensive compounds in ants, stick insects, rove beetles and leaf beetle larvae. Some of the group (e.g. the isomer of nepetalactone shown in Figure 6.12) are also sex pheromones in aphids. Reaction of iridomyrmecin with...
