| 2005～2009年在广州松材线虫病老疫区系统开展了疑似病死松树的早期诊断、引诱剂和林间释放花绒寄甲控制松褐天牛、病死木套袋熏蒸和疫区松林植物群落结构改造等持续控制技术研究。结果表明：疫区内松树枯死木的松材线虫的检出率为22.1%～55.4%。诱到松褐天牛成虫19853头，每个诱捕器的诱虫量为15.4～24.8头/年。释放放花绒寄甲成虫1115头，寄生率为9.21%～60.0%。清理枯死木14769株，熏蒸袋内的松褐天牛死亡率达到99.5%以上。在松林内套种39种阔叶树共112000株，改善了松林的植物群落结构，提高了松林对松褐天牛及松材线虫病的抗性。 |

| Abstract: |
| The sustainable control technology research on pine wood nematode (Bursaphelenchus xylophilis) and pine sawyer beetle ( Monochamus alternatus ) have been carried out in Guangzhou old epidemic areas from 2005 to 2009. The main technical measures including (1) Early diagnosis of pine wilt disease; (2) Control and monitor the adults M. alternatus by attractant; (3) Control pine sawyer beetles by releasing Dastarcus helophoroides; (4) Clean up dead trees and extinguish pests in woodlands; (5) Modification on the plant community structure in pine forest. The results showed that the detection rate of B. xylophilis from dead trees is 22.1%～55.4%; 19583 adults of M. alternatus have been trap in the test area, and 15.4～24.8 adults per trap set in a year; 1115 D. helophoroides were released in the pine forest, and the parasitism rate is 9.21%～60.0%; 14769 dead trees have been clean up, the mortality rate of M. alternatus larva or pupae is up to 99.5%; 112000 broadleaf trees (39 species) were planted in the pine forests, the plant community gets higher resistance to pine sawyer and pine wood nematode disease. |
