The problem of pollution effect on insects requires careful research. It is necessary to work out ways to reduce this impact on insects, if the pollution does not aim to destroy it. The purpose of the study was to investigate the effect of heavy metals on the species composition and population of Cynips (Neuroterus numismalis and Diplolepis quercus folii) in the overgrown oak forests of green zones. The main test - the object was a Neuroterus numismalis and Diplolepis quercus folii. The main research was carried out in coppice oak forests of the green zone of Voronezh (Russian Federation) in the Pravoberezhnoye forestry in quarters 33 and 35 along the M-4 “Don” highway. The ability of a Neuroterus numismalis to selectively populate oak leaves with an increased concentration of heavy metals puts it in the category of the most effective bio-indicators among the Cynips. The gall of the Diplolepis quercus folii is most susceptible to chemical contamination. With a low level of chemical contamination, the fecundity of the Diplolepis quercus folii and Neuroterus numismalis reaches a maximum level and decreases (in the Neuroterus numismalis one more sharply) with an average level of pollution.

污染对昆虫的影响问题需要仔细研究。如果污染不是为了消灭它，就必须想办法减少这种对昆虫的影响。本研究的目的是调查重金属对绿区杂草丛生的橡树林中的Cynips ( Neuroterus numismalis和Diplolepis quercus folii)物种组成和种群的影响。主要测试 - 对象是Neuroterus numismalis和Diplolepis quercus folii。主要研究是在 M-4 “Don”高速公路沿线 33 和 35 区的 Pravoberezhnoye 林业沃罗涅日（俄罗斯联邦）绿色地带的矮林栎林中进行的。Neuroterus numismalis的能力选择性地在橡树叶中增加重金属浓度，使其成为Cynips 中最有效的生物指标之一。Diplolepis quercus folii的瘿最容易受到化学污染。在化学污染水平较低的情况下，Diplolepis quercus folii和Neuroterus numismalis的繁殖力达到最高水平，并在平均污染水平下下降（在Neuroterus numismalis中更为急剧）。
