The aphid Pseudoregma sundanica (Van der Goot) (Homoptera: Aphididae) has two defence strategies. It is obligatorily tended by various species of ant and also produces sterile soldiers. We investigated how they allocate their investment in these two strategies. We measured the size, number of soldiers, number and species of tending ant, and number and species of predators in P. sundanica populations. We found that the level of ant tending correlated negatively with soldier investment in P. sundanica. The species of tending ant also influenced soldier investment. We excluded ants from aphid populations and recorded changes in population size and structure over four weeks. Ant exclusion led to population decline and extinction. At the same time, surviving populations showed a significant increase in soldier investment. The data demonstrate that social aphids can adjust their investment in soldiers in direct response to environmental change.
蚜虫伪角倍蚜（范德古特）（同翅目：蚜科）有两种防御策略。它必须由多种蚂蚁照料，并且还会产生不育的兵蚜。我们研究了它们如何在这两种策略上分配资源。我们测量了伪角倍蚜种群中兵蚜的大小、数量、照料蚂蚁的数量和种类，以及捕食者的数量和种类。我们发现，蚂蚁照料的程度与伪角倍蚜中兵蚜的投入呈负相关。照料蚂蚁的种类也会影响兵蚜的投入。我们将蚂蚁从蚜虫种群中排除，并记录了四周内种群大小和结构的变化。排除蚂蚁导致种群数量下降和灭绝。与此同时，存活的种群中兵蚜的投入显著增加。数据表明，社会性蚜虫可以直接响应环境变化来调整它们在兵蚜上的投入。
