The pine bark beetle (B. piniperda L.) has become the most destructive pest in the stands of Pinus yunnanensis in Kunming district and other forest regions in Yunnan Province. This paper reports the primary results of studies on bionomics and management of the pest at both Haikou and Fangwang tree farms during 1983-1986. The insect completes one generation a year. It overwinters in the adult stage without apparent hibernation. A certain proportion of the overwintering adults make second attacks on the host trunk...

The pine bark beetle (B. piniperda L.) has become the most destructive pest in the stands of Pinus yunnanensis in Kunming district and other forest regions in Yunnan Province. This paper reports the primary results of studies on bionomics and management of the pest at both Haikou and Fangwang tree farms during 1983-1986. The insect completes one generation a year. It overwinters in the adult stage without apparent hibernation. A certain proportion of the overwintering adults make second attacks on the host trunk after reemergence, and therefore are capable of establishing sister broods, The life stages of the within-tree broods are rather overlaping. However, the peak period of the population abundance in the host occures during Feb. —April. This suggests the proper time for treating the infestation spots, including bark-peeling. The attacking behavior of the beetle and its gallery pattern are described in the text. Our work also reveals that the forest fire-injured stands are pro-minent among the causal factors identified as contributing to host susceptibility. An extraordinary low-temperature attack in spring may cause a mortality rate of above 60% to the larval brood within the host. An Ostomatid (Temnochila sp.) predator is of importance among the natural enemies of the pest. It is observed that 3—4 larvae of this beneficial beetle are capable of devouring 53.8% of the pest population in a gallery. In suggesting the bark beetle management, treatments a brief review of both the domestic and world informations on the bark beetle control is presented. The authors urgently emphasize the significance of silvicultural practices in reducing susceptibility of stands to beetle attacks. They also stress the importance of implementing frequent detection on the active infestation spots and prompt treatment to suppress the populatien under infestation level.

本文报道了松纵坑切梢小蠹(Blastophagus piniperda L.)生物学特性研究的初步结果:在昆明一年发生一代,以成虫越冬,无明显冬蛰现象;部分越冬成虫两次侵蛀寄主树干繁殖,产生妹姊世代,树皮下各虫态群体峰期为2—4月。火烧迹地等易导致为小蠹虫源。反常的初春低温可造成60%以上的幼虫死亡;一种谷盗(Temnochila sp.)对寄主内小蠹种群的捕食率达53.8%。在合理落实营林管理,促进林分正常生长的基础上,做好经常性的虫情监测,经过清理蠹害虫源(特别包括新侵害木),以期小蠹种群长期处于经济为害水平以下。

Investigated insect pest of logs of Tahe forest district by taking advantage of sampling inspection. The results show that the common and serious insect species are monchamus sutor L. which damaged logs. Water storage method, brushing method and fumigant treatment are used to kill insect testing depend on biological nature of the insect. Experiment done shows that these methods are available in practice to preserve fire-damaged logs, especially phostoxin as fumigant treatment is successful. The method...

Investigated insect pest of logs of Tahe forest district by taking advantage of sampling inspection. The results show that the common and serious insect species are monchamus sutor L. which damaged logs. Water storage method, brushing method and fumigant treatment are used to kill insect testing depend on biological nature of the insect. Experiment done shows that these methods are available in practice to preserve fire-damaged logs, especially phostoxin as fumigant treatment is successful. The method involved follow characteristics: Operation simple; confidence and safety; penetration easy; effect of killing insect is very strong.

本研究对塔河林区火烧原木害虫进行了抽样调量,确定云杉小黑大牛(Monochamus sutor L.)是威胁木材的主要害虫,并根据其生物学特性,进行了水存法、涂刷法和熏蒸法等一系列现场治理试验。试验结果表明,采用这些方法保存火烧原木均行之有效。其中,熏蒸法选用磷化铝作熏蒸剂,具有使用方便、安全可靠、渗透力强、杀虫效果显著等特点。

The highest frequency of forest fire is production firing in Lishui Area. The forest fire often occurs in March. 11 to 15 o'clock are the heights of forest fire. The forest fire is restricted by meteorological factor. For preventing forest fire, We must define the fire warning period of the forest, control strictly fire source, carry out calculation and foreast of fire-danger, get additional fire provention and tame fire with the law.

丽水地区森林火灾频率最高的是生产用火;林火发生以三月份最多;11时至15时为林火发生的高峰;林火受气象因子的制约。预防森林火灾,应确定森林防火警戒期,严格控制火源,开展火险预测预报,增设防火措施和以法治火。
