【摘要】 对蛀梢期云南切梢小蠹(Tomicus yunnanensis)、短毛切梢小蠹(T.brevipilosus)和横坑切梢小蠹(T.minor)对云南松和华山松不同组织和器官为味源选择性进行室内生测。结果表明:离味源不同距离(3和20cm)条件下,3种小蠹两性均对被危害过的云南松梢有较强的选择性;对其他味源则无明显的选择性;且在味源区停留的时间云南松大于华山松。更多还原

【Abstract】 A series of bioassays of Tomicus. yunnanensis, T.brevipilosus and T.minor were conducted the selectivity to tissues and organs of Pinus.yunnanensis and P.armandii during the shoot feeding period. The results showed that these bark beetles more attractive P.yunnanensis shoots damaged than other odor sources. Compared with P.armandii, the bark beetles were longer at spent time in odor sources zone, when some parts of P.yunnanensis become odor sources.更多还原
