摘要:
以连香树精油为试材,探究其对桃蚜和台湾韭蚜的杀虫活性,旨在寻找天然有效的杀虫剂.通过对2种受试蚜虫实施熏蒸实验和触杀实验,求得其校正死亡率.分析在不同时间段的回归方程,进而评估连香树精油的杀虫活性.结果表明,在熏蒸实验中,对桃蚜来说,随着连香树精油处理体积分数的增加,杀虫效果逐渐增强,当体积分数达到200 μL/mL且处理时间为48 h,校正死亡率达到最大,为100%; 而对台湾韭蚜来说,体积分数为200 μL/mL的连香树精油处理12 h,校正死亡率即可达到100%,表明台湾韭蚜对连香树精油的敏感性更强.另外,在对台湾韭蚜的研究中还发现,低体积分数的连香树精油处理后,随着处理时间的延长,也有100%的校正死亡率,即体积分数为100 μL/mL的连香树精油在处理72 h和体积分数为50 μL/mL的连香树精油处理96 h后,校正死亡率亦可以达到100%.在触杀实验中,对于桃蚜来说,随着连香树精油处理体积分数的增加,杀虫效果越明显,当200 μL/mL的连香树精油处理96 h后,校正死亡率为100%; 同样,对于台湾韭蚜来说,随着连香树精油处理体积分数的增加,杀虫效果亦明显,且200 μL/mL的连香树精油在处理12 h后,校正死亡率就达到了100%.该结果亦表明台湾韭蚜对连香树精油的敏感性更强.综上所述,连香树精油具有较好的杀蚜活性,且对台湾韭蚜的杀伤能力要高于桃蚜.该研究为开发天然杀虫剂打下了良好的基础.
Abstract:
The aim of study was to find natural pesticides through exploring insecticidal activity of Myzus persicae and Neotoxoptera formosana with Cercidiphyllum japonicum oil. Through fumigation experiment and insecticidal experiment, the corrected mortality was pointed out and the toxicology regression equation was analysed in different time periods, and the insecticidal activity of Cercidiphyllum japonicum oil was evaluated. The results showed that the effect of insecticidal activity was strengthened gradually with the increase of concentration of Cercidiphyllum japonicum oil for Myzus persicae in fumigation experiment. When the concentration of Cercidiphyllum japonicum oil was 200 μL/mL and the processing time was 48 h, the corrected mortality would arrive at maximum(100%). For Neotoxoptera formosana, when experimental conditions were 200 μL/mL and 12 h, the corrected mortality could reach 100%. So, the Neotoxoptera formosana has stronger sensitivity for Cercidiphyllum japonicum oil. In addition, the study also found that the corrected mortality for Neotoxoptera formosana reached 100% with low concentration of Cercidiphyllum japonicum oil by increasing the time of treatment. Namely, when the Cercidiphyllum japonicum oil concentration was 100 μL/mL, treatment time was 72 h and when the Cercidiphyllum japonicum oil concentration was 50 μL/mL, treatment time was 96 h, the corrected mortality could also reach 100%. However, the effect of insecticidal activity was strengthened gradually with the increase of concentration of Cercidiphyllum japonicum oil for Myzus persicae in insecticidal experiment. When the concentration of Cercidiphyllum japonicum oil was 200 μL/mL and the treatment time was 96 h, the corrected mortality was 100%. Similarly, the effect of insecticidal activity was strengthened gradually with the increase of concentration of Cercidiphyllum japonicum oil for Neotoxoptera formosana. When the concentration of Cercidiphyllum japonicum oil was 200 μL/mL and the treatment time was 12 h, the corrected mortality had reached 100%. The results also showed that the Neotoxoptera formosana has stronger sensitivity for Cercidiphyllum japonicum oil. In a word, Cercidiphyllum japonicum oil showed good aphicidal activity and had stronger sensitivity for Neotoxoptera formosana. This study was a good basic for the development of natural insecticide.
