家蝇信息素对家蝇引诱效果观察

目的 :了解家蝇信息素对家蝇的引诱效果。方法 :在实验室用强迫接触法测试快速击杀效果及 2 4h死亡率 ,用方箱法测试引诱效果 ;在现场观察 2种药物的持续效果。结果 :KT50 氨基甲酸酯类涂抹剂是 2 .17min ,新型有机磷类涂抹剂是 1.92min ,2种涂抹剂 2 4h均为 10 0 %。引诱试验 (3 0min引诱家蝇只数 ) ,氨基甲酸酯类涂抹剂 2 2只 ,颗粒剂 12只 ,单纯氨基甲酸酯类药剂 3只 ;新型有机磷类涂抹剂 2 3只 ,颗粒剂 11只 ,单纯新型有机磷类药剂 4只。现场用涂抹剂及颗粒剂观察持效 ,观察第 1、5、10、2 0、3 0d记录 ,氨基甲酸酯类涂抹剂是 192、15 4、73、47、1只 ,颗粒剂是 178、10 2、41、19、2只 ;新型有机磷类涂抹剂是 2 0 9、172、117、88、5 4只 ,颗粒剂是 160、14 6、10 5、5 0、2 4只。结论 :2种涂抹剂对家蝇都具有较好速杀效果和较强的引诱能力 ,涂抹剂中加入引诱剂后诱杀效果提高了 5倍。

An Observation of Luring Effect of Muscalure on Musca domestica

Objective:To study the effect and level of attraction of pheromone on Musca domestica . Methods: In laboratory the forced contact method was used to examine the quick killing effect and the mortality rate within 24 h, and the square box method was used to examine the effect of attraction. In field the effect of duration of two insecticides was observed. Results: KT 50 was 2.17 min and 1.92 min for carbamate and organophosphorus smear insecticide respectively, and the mortality rate was 100% within 24 h for both smear insecticides. The number of Musca domestica within 30 min in the test of attraction was 22 for carbamate smear insecticides, 12 for granular insecticides, and 3 for simple carbamate smear insecticides; 23 for new-type organophosphorus smear insecticides, 11 for granular insecticides, and 4 for simple new-type organophosphorus insecticides. Smear and granular insecticides were used in the field experiment to observe the effect of duration. In the records on the 1 st , 5 th ,10 th ,20 th and 30 th day, the number of Musca domestica was 192,154,73,47 and 1 for carbamate smear insecticides, and 178,102,41,19 and 2 for granular insecticides; 209,172,117,88 and 54 for new-type organophosphorus smear insecticides, and 160,146,105,50 and 24 for granular insecticides. Conclusion: Both smear insecticides had better quick killing effect and stronger attraction, and effect of attraction had been raised 5 times after attractant fortified in the smear insecticides.
