| 摘 要： | 台湾乳白蚁Coptotermes formosanus Shiraki是华南地区农林树木、木质构件的重要钻蛀性害虫。本文测定分析了二氧化碳(CO2)对台湾乳白蚁的引诱效果。分析结果显示,二氧化碳对台湾乳白蚁具有显著的引诱活性,其中浓度1.5%的二氧化碳对台湾乳白蚁的引诱作用较强,但引诱作用随着二氧化碳浓度的升高而减小。为了便于应用,进一步利用发酵产生的二氧化碳分析,结果显示二氧化碳较常规引诱物松木具有更显著的引诱效果。本研究将为台湾乳白蚁新型引诱剂开发提供参考,有助于提高台湾乳白蚁饵剂的防治效果。

| Abstract: | Bacterial strains W12 and W118,isolated from the rhizosphere soil of tomato in Ningbo,could antago-nize against Ralstonia solanacearum .Based on the 16S rDNA sequence analysis,W12 and W118 were preliminari-ly identified as Bacillus spp.The genes responsible for biosynthesis of bacillomycin,iturin and fengycin were identified in both W12 and W118 strains by PCR amplification.The field trials showed that the control effect of mixed bacterial suspension of W12 and W118 reached 62.3% after irrigations for three times,while when used alone,the control effect of strain W118 was 56.7%,which was better than that of strain W12. |
