摘要
为评估粘胶色板对茶园昆虫诱捕作用及用于防治主要害虫的可能性,制作了芽绿、橄榄黄绿、素馨黄和雪白色板,于各类昆虫盛发的7月在重庆市郊、浙江松阳县和安徽省麻姑山茶场各0.5hm2的茶园做了48h诱捕试验。诱捕的绝大多数昆虫为同翅目害虫;害虫很多而天敌极少,害虫与天敌的个体数量差异极显著。芽绿、橄榄黄绿和素馨黄色板对假眼小绿叶蝉成、若虫和黑刺粉虱成虫的诱效显著大于雪白色板的诱效;从芽绿、橄榄黄绿至素馨黄,绿色色素成分减少、黄色色素成分增多,诱捕的叶蝉数减小而粉虱数增大。可将芽绿、素馨黄色板分别用于叶蝉成、若虫和粉虱成虫的诱捕。
In order to evaluate the entrapping effect of the bud green, the olive yellow-green, the jasmine yellow and the snow white sticky plates on various insects in tea gardens and to discuss the possibility for them to be applied in controlling the important pests, the luving tests, were conducted. In July when the various species of insects occurred in tea gardens, the plates were set in 0.5 hma tea gardens to trap the insects for 48 h, in the tea gardens of Chongqing Suburbs, in Songyang County of Zhejiang Province and in Magushan Tea Farm of Anhui Province, respectively. The results showed that the most of trapped insects belonged to Homoptera, in which the attracted amounts of harmful insects was abundant whilst the those of beneficial insects was much small, and the difference in both amounts reached the level of P?0.01. Bud green, olive yellow-green, jasmine yellow and snow white sticky plates showed much stronger trapping effect on nymphs and adults of tea green leafhoppers and adults of citrus spiny whiteflies than snow-white stiky plates. From bud green, olive yellow-green to jasmine yellow, green ingredient decreased whilst yellow ingredient increased, accordingly, the number of trapped leafhoppers decreased whilst the number of trapped whiteflies increased. It is proposed that bud green and jasmine yellow sticky plates could be used to trap the leafhoppers and the whiteflies, respectively.
