利用ZXX-65真空循环熏蒸设备杀灭臭椿沟眶象的研究

Use of ZXX-65 vacuum circulatory fumigation equipment against Eucryptorrhynchus brandti (Harold)

利用ZXX 6 5真空循环设备通过不同的熏蒸压力、浓度、时间条件组合 ,对感染奥椿沟眶象Eucryptorrhynchusbrandti (Harold)的臭椿带皮原木进行了熏蒸实验。结果表明 ,ZXX 6 5真空循环设备可在 2h内杀死臭椿沟眶象 (成虫、幼虫、蛹 )。 2 0 0 0 0Pa、 2h、溴甲烷 (CH3Br)4 0

Experiments were made with different combinations of fumigation pressures,time and concentrations to fumigate Eucryptorrhynchus brandti infested logs of tree of heaven by ZXX-65 vacuum circulatory fumigation equipment.The results showed that the (equipment) could successfully kill the (weevil) including adult,larva and pupa.The fumigation (condition) of 20000 Pa,2 h,40 g/m 3(CH 3Br) was the best combination against the (weevil) for quarantine.
