黄板对茶园昆虫类群的诱捕效果分析

昆虫与植物之间色彩通讯是彼此信息交流的渠道之一，基于害虫趋色性研发的诱虫板作为一种绿色防控手段，已广泛应用于农林害虫的防控和预测预报。为了明确黄色诱虫板在茶园害虫多样性调查和防治中的效果，我们于2018年7月~8月对井冈山大井茶园里的黄色诱虫板的诱捕情况进行了调查研究。研究结果表明：黄板对茶园双翅目、膜翅目、半翅目、鞘翅目和鳞翅目昆虫诱捕效果最佳，直翅目害虫诱捕效果较差，且不同类群间数量差异极其显著。阳面诱捕的昆虫总数量多于阴面（V=1450.5，P=0.0032），不同类群诱捕效果的分析表明：双翅目（Wilcoxon符号秩检验，V=1525，P=0.017）、半翅目（Wilcoxon符号秩检验，V=1233.5，P=0.044）、鳞翅目（Wilcoxon符号秩检验，V=244，P<0.001）、膜翅目（Wilcoxon符号秩检验，V=818.5，p<0.001）双面诱捕数量存在显著差异，且阳面均多于阴面。相关性分析表明半翅目—鳞翅目（r=0.75，P<0.001）、半翅目—膜翅目（r=0.55，P<0.001）、半翅目—鞘翅目（r=0.58，P<0.001）、鳞翅目—膜翅目（r=0.53，P<0.001）、鳞翅目—鞘翅目（r=0.71,P<0.001）、膜翅目—鞘翅目（r=0.63，P<0.001）间诱捕数量上存在正相关。

ANALYSIS OF THE EFFECT OF YELLOW BOARD ON THE INSECT GROUPS IN TEA GARDEN

Color communication between insects and plants is one of the channels for information exchange between each other. The traps developed based on the color preference of pests as a green prevention and control method have been widely used in the prevention, control and prediction of agricultural and forestry pests. In order to clarify the effect of yellow traps on the control of pests in tea gardens, we investigated the insect trapping of yellow traps in the Dajing tea garden of Jinggangshan from July to August 2018. The results showed that the yellow plate had the best trapping effect on Diptera, Hymenoptera, Hemiptera, Coleoptera and Lepidoptera, and the trapping effect of Orthoptera pests was poor, and the difference among different groups was extremely significant. The total number of insects trapped on the sunny side was more than that on the shady surface (V=1450.5, P=0.0032). The analysis of trapping effects of different groups showed: There is a significant difference in Diptera (Wilcoxon signed rank test, V=1525, P=0.017), Hemiptera (Wilcoxon signed rank test, V=1233.5, P=0.044), Lepidoptera (Wilcoxon signed rank test, V=244, P<0.001), Hymenoptera (Wilcoxon signed rank test, V=818.5, P<0.001), and the sunny side is more than that on the shady surface. Correlation analysis showed that There is a positive correlation between the Hemiptera-Lepidoptera (r=0.75, p<0.001), Hemiptera-Hymenoptera (r=0.55, P<0.001), Hemiptera-Coleoptera (r=0.58, P<0.001), Lepidoptera-Hymenoptera (r=0.53, P<0.001), Lepidoptera-Coleoptera(r=0.71, P<0.001), Hymenoptera-Coleoptera (r=0.63, P<0.001).
