红脂大小蠹是原产北美近年传入我国的一种危险性森林害虫 ,生活隐蔽 ,防治难度很大。为筛选出对我国油松林中红脂大小蠹种群有高效引诱作用的药剂 ,为今后控制红脂大小蠹的危害提供经济、实用、高效的监测方法和防治技术提供技术和物质依据 ,作者于 2 0 0 2年 5～ 7月在石家庄井陉和邢台内丘两地 ,先后进行了连续 2次的引诱试验。试验以加拿大生产的商品和松节油分别作为对照 ,共对 2 7种不同药剂的林间引诱效果进行了测定。试验结果表明 ,2B -7号引诱剂引诱效果显著好于加拿大对照 (a=0 .0 1 4) ,每个诱捕器平均诱虫数量比加拿大引诱剂多 96.3 9%。初步测算其成本比购买加拿大产品低 3 0 %～ 5 0 %以上。
Red Beetles is a native North American origin in recent years into our country a dangerous forest pests, hidden life, prevention and treatment is very difficult. In order to screen out the effective inducing agents for the red beetle population in Chinese pine forest and provide the technical and material basis for the future economic, practical and efficient monitoring and control of the damage caused by the red beetles, From May to July in 2002, Shijiazhuang Jingtai and Xingtai Neiqiu both conducted successively two consecutive lure tests. Tests were conducted in Canada for the production of goods and turpentine respectively as a control, a total of 27 different kinds of agents of the tree lure effect were determined. The results showed that the attraction of 2B-7 attractant was significantly better than that of Canadian control (a = 0.014), and the average number of induced insects per trap was 96.39% more than that of Canadian attractants. Preliminary estimates of its cost than the purchase of Canadian products 30% ~ 50% or more.
