摘要
性信息素加病毒诱芯技术是利用昆虫性信息素和昆虫病毒控制害虫种群水平的一种新的自传播技术。风洞试验已证实该技术的可行性。林间试验结果表明，在每５株泡桐树上悬挂１个诱芯的条件下，在３００ｍ×３００ｍ的处理区中央设置的诱捕器在试验期间每日都诱捕到了接触过诱芯而污染上病毒的大袋蛾雄蛾。在处理区中央人工悬挂的２９．２％的处女雌虫因与带有病毒的雄蛾交尾而被污染上病毒。被病毒污染的雌虫产的卵中孵化出的幼虫中，其ＣＶＮＰＶ病虫的死亡率达７３．２％。因此，该试验证实了性信息素加病毒诱芯技术在林间条件下的可行性。
The sex pheromone plus virus dispenser technique is a type of autodissemination with which pest insect population levels can be controlled by using insect sex pheromone and insect virus. The feasibility of the technique has been confirmed by the experiments in the wind tunnel. The results of the field tests showed that under the conditions of hanging one dispenser for every five Paulownia elongata(S. Y. Hu)trees, traps set up in the centre of the 300m×300m treated plot caught male moths having visited the dispensers and being contaminated by the virus every day during the test period 29. 2% of virgin females set up in the centre of the treated plot were contaminated with the virus by mating with the males. The larval CVNPV disease mortality reached 73. 2% in the larvae emerged from the eggs laid by the contaminated females.Therefore, the field tests demonstrated the feasibility of the sex pheromone plus virus dispenser technique under the field conditions.
