开普弗罗里斯特地区(CFR)是世界上植物物种最丰富的地区之一。它也是一个暖温带地区，假设应该有很高的胆虫物种丰富，这使得研究该地区的昆虫与丰富的植物区系之间的关系是很有趣的。研究了赤眼蜂和整个CFR植被代表的胆虫物种丰富度(GSR)与植物丰富度的关系。对木本灌木的样本(每样地多达600株)进行了调查，以确定是否存在虫害。对这些昆虫的物种丰富度进行了量化，并对每个样带的植物物种丰富度进行了量化。Fynbos的GSR与全球GSR数据进行了比较。与其他CFR植被类型相比，Fynbos拥有更多的胆小蜂种类。GSR与CFR植株丰富度呈正相关。GSR还密切跟踪了Fynbos的植物丰富度。GSR不受其他变量(海拔和坡向)的显著影响，这表明植物本身的丰富度是产生GSR的重要因素。Fynbos GSR与全球其他GSR较高的硬叶地区具有可比性，证实了这种植被类型有利于五倍子昆虫的多样化。在Fynbos中很可能有很高比例的胆小虫特有，这可以从这个昆虫群体的高寄主保真度中得到预期。
The Cape Floristic Region (CFR) is one of the most plant-species-rich regions in the world. It is also a warm temperate region and hypothetically should have high gall-insect species richness, making it interesting to investigate the relationship between the insects of the region and the rich flora. The relationship between gall-insect species richness (GSR) and plant richness was investigated for the Fynbos and for representatives of vegetation of the whole CFR. Samples (of up to 600 plants per transect for Fynbos) of woody shrubs were investigated for the presence of galls. The species richness of these insects was quantified, as well as plant species richness for each transect. GSR for Fynbos was compared to global figures for GSR. Fynbos harboured significantly more gall-insect species than other CFR vegetation types. GSR was positively correlated with CFR plant richness. GSR also closely tracked plant richness in Fynbos. GSR was not significantly influenced by other variables (elevation and aspect), suggesting that plant richness per se was an important factor in generating GSR. Fynbos GSR is comparable to other sclerophyllous regions of high GSR globally, corroborating that this vegetation type is conducive to gall-insect diversification. There is likely to be a high percentage of gall-insect endemism in the Fynbos, as might be expected from the high host fidelity of this insect group.
