Abstract

The present study aimed to increase knowledge about the diversity and factors that determine the distribution of galling insects in the Parque Nacional do Itatiaia (PNI), Southeast, Brazil. For this, collections were performed in April, August and November 2015 and March 2016. Seventy gall morphotypes were found in 12 families, 32 genera and 61 species of host plants. The richness of galls did not vary with altitude, but increased with the richness of plants. The families and genera of plants with greater species richness harbored a greater number of galling insects. The number of gall morphotypes was higher in the autumn than in the other seasons. The spatial distribution of galling insects was better explained by factors such as floristic richness and species composition than by ecological effects, represented here by altitude. Regarding seasonality, the results indicate that the way resources are temporarily distributed to galling insects depends on factors such as the active growth of host plants, making some periods of the year more conducive to the development of galls.

大西洋森林保护区（巴西东南部）鸡食昆虫的地理分布模式

本研究旨在增加对巴西东南部意大利国家公园（PNI）鸡食昆虫分布的多样性和决定因素的了解。为此，2015年4月、8月和11月以及2016年3月进行了收集。寄主植物共有61种32属12科70种。五倍子的丰富度不随海拔高度的变化而变化，而是随着植物的丰富度而增加。物种丰富度更高的植物科和属中有更多的令人讨厌的昆虫。秋季胆囊形态类型的数量高于其他季节。与以海拔为代表的生态效应相比，用植物区系丰富度和物种组成等因素更好地解释了令人恼火的昆虫的空间分布。关于季节性，研究结果表明，资源暂时分配给饲养昆虫的方式取决于寄主植物的活跃生长等因素，这使得一年中的某些时期更有利于galls的发育。
