Abstract

Feeding habits and competitive interactions among dominant grasshopper species in the Xinjiang grasslands (China) were studied under natural conditions through microscopic analyses of insect crop contents. Sex-specific and interindividual differences in feeding habits and interspecific competition were investigated. Analyses of ecological niche width and overlap revealed potential competition among grasshoppers. The results showed significant difference in the sex-specific variations in the feeding habits of the seven grasshoppers; sex-specific variations in feeding range and preferred plants were observed, with females feeding more extensively on host plants, and female and male adults choosing to feed on different plant species. Individuals of all seven grasshoppers showed different degrees of dietary variance, with oligophagous grasshoppers (Oedaleus decorus males, Dericorys annulata, and Bryodema gebleri males) showing a smaller degree of individual dietary variance than polyphagous grasshoppers (Oedipoda caerulescens, Calliptamus coelesyriensis females, Calliptamus barbarus, and Notostaurus albicornis); Calliptamus coelesyriensis and Notostaurus albicornis showed the greatest individual variance in their diets. Oedaleus decorus, Bryodema gebleri, and Calliptamus barbarus consumed primarily Poaceae and exhibited varying foot-plant choice. For example, Oedaleus decorus was observed to have high- preference feeding for Poa annua, Bryodema gebleri for Stipa capillata, and Calliptamus barbarus for Setaria viridis. Dericorys annulata fed primarily on Amaranthaceae, Notostaurus albicornis fed primarily on Poaceae and Amaranthaceae, and Oedipoda caerulescens fed primarily on Asteraceae. Calliptamus barbarus exhibited strong interspecific competition with Oedaleus decorus and Calliptamus coelesyriensis, and Bryodema gebleri demonstrated the strongest interspecific competition with all six other species. Considering the influence of sex on interspecific competition among grasshoppers enhances our understanding of interspecific competitive relationships.

新疆草原七种优势蚱蜢对食物植物的选择

通过对昆虫嗉囊内容物的显微分析，研究了新疆（中国）草原上主要蚱蜢物种在自然条件下的取食习性和竞争相互作用。研究了不同性别和个体间在取食习性和种间竞争方面的差异。生态位宽度和重叠分析揭示了蚱蜢之间潜在的竞争。结果表明，七种蚱蜢的取食习性存在明显的性别差异；取食范围和偏好植物存在性别差异，雌性蚱蜢更广泛地取食寄主植物，雌性和雄性成虫选择取食不同种类的植物。所有七种蚱蜢的个体都表现出不同程度的食性差异，寡食性蚱蜢（Oedaleus decorus雄性、Dericorys annulata和Bryodema gebleri雄性）的个体食性差异小于多食性蚱蜢（Oedipoda caerulescens、Calliptamus coelesyriensis雌性、Calliptamus barbarus和Notostaurus albicornis）；Calliptamus coelesyriensis 和 Notostaurus albicornis 的食性个体差异最大。Oedaleus decorus、Bryodema gebleri和Calliptamus barbarus主要食用禾本科植物，对足类植物的选择各不相同。例如，观察到 Oedaleus decorus 最喜欢采食 annua 蒲草，Bryodema gebleri 最喜欢采食 capillata Stipa，Calliptamus barbarus 最喜欢采食 viridis Setaria。Dericorys annulata 主要取食苋科植物，Notostaurus albicornis 主要取食蒲科植物和苋科植物，Oedipoda caerulescens 主要取食菊科植物。Calliptamus barbarus 与 Oedaleus decorus 和 Calliptamus coelesyriensis 之间的种间竞争十分激烈，而 Bryodema gebleri 与其他六个物种之间的种间竞争最为激烈。考虑到性别对蚱蜢种间竞争的影响，可以加深我们对种间竞争关系的理解。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
