本研究的目的是调查两个主要基因的表达水平，气味结合蛋白Gp-9（一般蛋白-9）和觅食，已被证明与蚂蚁的行为多态性。我们分析了工人和年轻的nonreproductive皇后收集巢的单雌（单生殖皇后每巢）和polygyne（多个生殖皇后）的社会形式红火蚁。在工人，但不是年轻的皇后，觅食的表达水平显着相关的社会形式和执行的任务（即本地化的巢或觅食区）。Gp-9的表达水平也与社会形式和工人本地化有关。此外，与Gp-9（B）等位基因相比，在杂合子工蜂和年轻的非生殖蜂王中，Gp-9（B）等位基因的表达水平更高。最后，在多雌生殖群落中，觅食的表达水平与工蜂或年轻非生殖蜂王的Gp-9基因型没有显着相关，这表明这两个基因对入侵蜂群的行为具有独立的非上位性影响。
The aim of this study was to investigate levels of expression of two major genes, the odorant binding protein Gp-9 (general protein-9) and foraging, that have been shown to be associated with behavioural polymorphisms in ants. We analysed workers and young nonreproductive queens collected from nests of the monogyne (single reproductive queen per nest) and polygyne (multiple reproductive queens) social forms of Solenopsis invicta. In workers but not young queens, the level of foraging expression was significantly associated with social form and the task performed (ie localization in the nest or foraging area). The level of expression of Gp-9 was also associated with social form and worker localization. In addition there was a higher level of expression of the Gp-9(b) allele compared with the Gp-9(B) allele in the heterozygote workers and the young nonreproductive queens. Finally, in the polygyne colonies the level of expression of foraging was not significantly associated with the Gp-9 genotype for either workers or young nonreproductive queens, suggesting that both genes have independent non-epistatic effects on behaviour in S.invicta.
