Abstract

The German cockroach is a valuable model for research on indoor pest management strategies and for understanding mechanisms of adaptive evolution under intense anthropogenic selection. Under the selection pressure of toxic baits, populations of the German cockroach have evolved a variety of physiological and behavioral resistance mechanisms. In this review, we focus on glucose aversion, an adaptive trait that underlies a behavioral resistance to baits. Taste polymorphism, a change in taste quality of glucose from sweet to bitter, causes cockroaches to avoid glucose-containing baits. We summarize recent findings, including the contribution of glucose aversion to olfactory learning-based avoidance of baits, aversion to other sugars, and assortative mating under sexual selection, which underscores the behavioral phenotype to all oligosaccharides that contain glucose. It is a remarkable example of how anthropogenic selection drove the evolution of an altered gustatory trait that reshapes the foraging ecology and sexual communication.

葡萄糖厌恶：德国小蠊的行为抵抗机制

德国小蠊是研究室内害虫管理策略和了解人类强烈选择下适应性进化机制的宝贵模型。在有毒毒饵的选择压力下，德国小蠊种群进化出了多种生理和行为抵抗机制。在这篇综述中，我们将重点讨论葡萄糖厌恶这一适应性特征，它是对毒饵产生行为抵抗力的基础。味觉多态性，即葡萄糖的味质由甜变苦，导致蟑螂避开含葡萄糖的诱饵。我们总结了最近的研究结果，包括葡萄糖厌恶对基于嗅觉学习的避开诱饵、厌恶其他糖类和性选择下的异性交配的贡献，这强调了蟑螂对所有含有葡萄糖的低聚糖的行为表型。这是一个非凡的例子，说明人类选择是如何推动改变味觉特征的进化，从而重塑觅食生态学和性交流的。

期刊介绍： Current Opinion in Insect Science is a new systematic review journal that aims to provide specialists with a unique and educational platform to keep up–to–date with the expanding volume of information published in the field of Insect Science. As this is such a broad discipline, we have determined themed sections each of which is reviewed once a year. The following 11 areas are covered by Current Opinion in Insect Science. -Ecology -Insect genomics -Global Change Biology -Molecular Physiology (Including Immunity) -Pests and Resistance -Parasites, Parasitoids and Biological Control -Behavioural Ecology -Development and Regulation -Social Insects -Neuroscience -Vectors and Medical and Veterinary Entomology There is also a section that changes every year to reflect hot topics in the field. Section Editors, who are major authorities in their area, are appointed by the Editors of the journal. They divide their section into a number of topics, ensuring that the field is comprehensively covered and that all issues of current importance are emphasized. Section Editors commission articles from leading scientists on each topic that they have selected and the commissioned authors write short review articles in which they present recent developments in their subject, emphasizing the aspects that, in their opinion, are most important. In addition, they provide short annotations to the papers that they consider to be most interesting from all those published in their topic over the previous year.
