松小蠹综合控制技术研究

为达到持续控制纵坑切梢小蠹(简称松小蠹)危害的目的，进行了松小蠹与云南松林分之间的关系、抚育间伐控制蠹害效果、蠹害木清理技术、聚集信息化合物引诱剂筛选及林问引诱技术、生物防治、化学防治等系列松小蠹综合控制技术研究。通过研究，初步探明了云南松林分与松小蠹危害之间的关系及受害林分内害虫的演变情况；证实了松小蠹生活史中姐妹代的存在，摸清了姐妹代各虫态出现的时期、种群数量，为松小蠹的防治提供了科学依据；筛选出4种效果较好的引诱剂配方及两种可供推广的诱捕器，研究了引诱剂林间引诱、测报方法及应用粉拟青霉菌杀虫剂防治扬飞期成虫技术，提出了一套完整的松小蠹综合控制措施。

Studies on the Integrated Control Techniques of Tomicus piniperda

To get sustainable control of pine shoot beetle, WTTomicus piniperda, a series studies on integrated control techniques have been made, including the relation between Tomicus piniperda and Pinus yunnanensis stand, effect of tending-thinning to control beetle damage, techniques of clearing damaged woods, selection of aggregation pheromone attractants, field attraction techniques, biological and chemical control etc. Through these researches, preliminary results showed the association of Yunnan pine stand and beetle damage, and the pest development in damaged stands. Confirmation of sister broods, emergence period and population of all beetle phases in sister broods life cycle provide scientific basis for beetle control. Systematic control measures have been advanced after 4 effective attractant formulas and 2 traps were selected, and field test of attractant, forecast methods and technique of flying beetle control using Paecilomyces farinosus were studied.
