Analysis of the obtained genome amplification showed that DNA after PCR presented obvious polymorphism, and the results were the same using the same primer to amplify the larva and imago of the same species. It indicates that RAPD technique can be applied to the identification of dry samples and dipped larva sample of longicorn beetles as well as the research of phylogeny. These three methods for extracting genome DNA from different species of longicorn beetles at different preserved time are feasible.
对所获得的基因组扩增分析表明,经过PCR之后的DNA能呈现明显的多态性,同种天牛用同一引物扩增幼虫和成虫所获得的结果相同,可以认为,RAPD技术可以应用于天牛成虫干标本及幼虫浸渍标本的鉴定及系统发育研究中,也证明了这3种方法用于提取不同保存时间、不同种天牛基因组的DNA是切实可行的。

The results of The biological characteristics of Semanotus bifasciatus have showed: 1. The hole of Semanotus bifasciatus associated with a certain temperature.2.The main damages of Semanotus bifasciatus located oriental arborvitae tree trunks, while above 3m parts are not damaged. 3.The Mating numbers of Semanotus bifasciatus are not unique ,and the duration varied due to the different individuals, the average duration is 3.2 minutes . 4. when are flying , they are more sensitive to blue and green; while moved, they are more sensitive to black.
对双条杉天牛的生物学特性的研究结果表明:双条杉天牛出孔与温度有一定的相关性,温度过低,双条杉天牛停止出孔;对于树高7m以上的树,主要危害侧柏基部的1-3m的主干部分,3m以上基本不受害;双条杉天牛需要经过一段时间的抱合才能交尾,交配对象不专一,雌雄成虫均可以多次交尾,交尾时间长短不一,平均3.2min/次;飞行时对蓝色和绿色较为敏感,爬行时对黑色较为敏感。

Result shows that the Apriona germari adult insect prefer to eat Broussonetia papyrfera and reject to eat other tree species which result in difference in natural life and fecundity. Total sugar and dissolvable protein content in the bark is not the cause of rejection. Difference of dissolvable sugar and amino acid may be the reason of preference while difference of dissolvable phenolics and tannin content may explain the rejection.
取食构树的桑天牛成虫取食量大,存活时间长,产卵量大,遗卵量少,其他3个树种则相反。4树种树皮内总糖和可溶性蛋白含量与桑天牛抗性无关,树皮内可溶性糖含量、总氨基酸和必需氨基酸含量对抗性有一定影响。4树种树皮内水溶性总酚含量和单宁含量差异对成虫取食有较大影响,酚类和单宁等次生物质对桑天牛成虫的忌避作用是导致抗性的主要原因。

Anoplophora glabripennis Motshulsky (Coleoptera: Cerambycidae) is one of the most destructive insect borers of poplar trees in China. In recent years millions of poplar trees were damaged to death or near death in"Three-North Area", which caused heavy losses economically, ecologically and socially. Through the study on host selecting behaviors and behavioral responses to plant volatiles of A.

The EAG results showed that no significant difference between female and male S.bifasciatus.The EAG responses of S.bifasciatus to 3-Carene,Limonene,Terpinene and Thujopsene were increased with the concentration respecitively within the range of 1/1000-1/10.The results of "Y" tube olfactory bioassay showed the pests can be attracted by 1/100 Limonene,3-Carene and Thujopsene.Original and 1/10 Terpinene was the best. In addition,the extracts of A2 and D1 also caused positive attraction to S.bifasciatus,while the extracts by SE and SDE were non-attractive.
触角电位测定结果表明,双条杉天牛雌雄成虫对样品的EAG反应无显著差异。1/10浓度的3-蒈烯、柠檬烯、萜品烯和罗汉柏烯的EAG值最大。Y型嗅觉行为生测结果表明,1/100浓度的柠檬烯、3-蒈烯和罗汉柏烯对天牛有明显引诱效果,萜品烯则是原液和1/10浓度的引诱效果最好;α-蒎烯和β-蒎烯无明显引诱效果。4种提取方法中,改装简易蒸馏法样品(A2)和超临界CO_2萃取样品(D1)对天牛具有明显引诱作用;索氏提取物和并时蒸馏萃取物无引诱效果。

Someone thought they are belong to a same species, and someone thought to be two species, and still existed dispute in this problem. According to some reports, many research persons of Ningxia did not distinguish this two kinds of longicorns, in thesis "Anoplophora glabripennis" containing the individual of A.
据了解,宁夏许多研究者未将这两种天牛区分研究,论文中的&光肩星天牛&实际上都包含着&黄斑星天牛&的个体,实际研究中也的确很难准确区分这两种天牛,因为时常发现既不属于光肩星天牛,也不属于黄斑星天牛的中间类型。

Contrast tests in three places during 1997 and 1998 showed that the trapping capability of 450Wlight was obviously stronger than that of 20W light.The fluctuation of trapped japanese pine sawyer,Monochamus alternatus was consistent with that of natural emergence.The pine wilt nematodeBursaphelenchus xylophilus can be extracted from trapped male and female adult bodies of JPS.
三地两年的对比试验结果表明,450W高压汞灯诱杀松墨天牛Monochamus alternatus Hope效果明显优于20W黑光灯,灯光引诱结果与松墨天牛自然羽出情况基本一致,灯光诱集的松墨天牛雌雄成虫体上均可分离到松材线虫Bursaphelenchus xylophilusNickle。
