The precise means by which socially parasitic gall aphids locate and exploit their hosts remain largely unknown. In this study, I investigated dispersal from natal galls by Tamalia inquiline aphids, both in terms of emigration from the gall, as well as the invasion of new galls induced by host Tamalia aphids. Experimental evidence, gained from sticky traps on the host plants, demonstrates that inquiline first-instar aphids are significantly more likely to exit natal galls than are gall-inducers. With the use of fluorescent tracking powder, a second set of trials confirmed that inquilines are capable of dispersing between galls on the host plant. These experiments reveal the locomotory capacity of Tamalia social parasites as a strategy for exploiting the galls of host aphids.

社会寄生的瘿蚜虫定位和利用其寄主的确切方式在很大程度上仍然未知。在这项研究中，我调查了Tamalia inquiline 蚜虫从出生瘿的扩散，包括从瘿的迁移以及寄主Tamalia蚜虫诱导的新瘿的入侵。从寄主植物上的粘性陷阱获得的实验证据表明，inquiline 一龄蚜虫比瘿诱导物更有可能退出出生瘿。通过使用荧光示踪粉，第二组试验证实 inquilines 能够分散在寄主植物的瘿体之间。这些实验揭示了塔玛利亚的运动能力 社会寄生虫作为利用寄主蚜虫瘿的策略。
