| 摘 要： | 在室内条件下采用喷雾法.以10%吡虫啉做对照,分别测定2种生物农药1.8%阿维菌素乳油、1%苦参碱可溶性液剂对小十三星瓢虫的敏感性试验.结果表明:供试药剂毒性大小依次为阿维菌素＞苦参碱＞吡虫啉(对照药剂).阿维菌素的毒力最高为LG50 3.71807 mg/L是对照药剂的3.96倍,其次苦参碱LG50 4.18463 mg/L是对照药剂的3.52倍,说明生物农药对小十三星瓢虫比较敏感,生物农药毒力高于对照药剂吡虫啉(新烟碱类)的毒力.

| Abstract: | The susceptibility experiment of two kinds of bio-pesticides to Adjoin variegata was evaluated using spraying apparatus in libarary.Imidacloprid 10% was contrast.The results showed that abamectin had higher toxicity,LC50 was 3.71807 mg/L,which was 3.96 times as much as contrast.The following was Matrine,LC50 was 4.18463 mg/L,which was 3.52 times as much as contrast.These indicated that it was susceptible bio-pesticides to Adjoin variegata and the toxicity of bio-pesticides was higher than imidacloprid. |
