１９９７年在兰考县调查了泡桐林内同翅目、半翅目昆虫种类，其在林内的分布以及调查期间的种群数量动态。共采获同翅目和半翅目昆虫计２７ 种，其中同翅目１１ 种、半翅目１６ 种。结果表明：不同种的数量差异极显著，而６ 种富集种的数量占调查捕获总数的９９．５６％ ，其中小绿叶蝉数量占总数的８８．８％ 。捕获的昆虫数量与诱虫器高度呈正相关，以黄色粘虫器为例，昆虫数量在黄板上与高度的关系为：ｙ＝ １０４．１４ｘ１．６７６ ６（Ｒ２＝ ０．９８０ ４）；表现在黄筒上为：ｙ＝ １０２．７６ｘ１．８２２ ３（Ｒ２＝ ０．９８０ ５）。粘虫器上昆虫的数量变化可以分为３ 个阶段：５ 月初至６ 月中旬为始盛期，６ 月下旬至９ 月中旬为发生高峰期，９ 月下旬至１１ 月逐渐消退并进入越冬期
In Lankao County, in 1997, the species of Homoptera, Heteroptera insects in the Paulownia forests, their distribution in the forest, and the population dynamics during the survey were investigated. A total of 27 species of Homoptera and Hemiptera insects were collected, of which 11 were Homoptera and 16 were Hemiptera. The results showed that there were significant differences in the numbers of different species, while the number of the six species accounted for 99.56% of the total number of captured surveys, of which 88.8% of the total number of green leafhoppers. The number of insects captured was positively correlated with the height of insect trap. For example, the number of insects on the yellow plate was: y = 104.14x1.676 6 (R2 = 0.980 4) On the yellow cylinder: y = 102.76x1.822 3 (R2 = 0.980 5). The number of insects in Mythimna separata Walker can be divided into three stages: the beginning of May to the middle of June, the peak of flowering from late June to mid-September, the gradual regression of late September to November and the overwintering period
