蝇类监测中不同饵料诱蝇效果的对比研究

Fly-luring effects of different baits in fly monitoring:a comparative study

目的了解不同配方饵料对蝇类的诱捕效果,探索蝇类监测饵料的商品化和标准化。方法用果酱、甜面酱、红糖、奶粉、腐鱼膏剂和鱼粉6种材料,按不同比例配置成9个配方,现场笼诱法比较配方的诱蝇效果。结果通过4-11月每月3次轮换试验,5号配方(腐鱼膏剂+甜面酱)对大头金蝇诱获率最高;6号配方(腐鱼膏剂+红糖+奶粉)对家蝇诱获率最高,家蝇占诱蝇总数的29.3%,经χ2检验,6号与1～3、5号差异有统计学意义,与4、7～9号差异无统计学意义。经Student-Newman-Keuls统计分析,6号配方优于其他配方,即6号>(9号、7号、4号、8号)>2号>3号>5号>1号。结论 6号配方优于其他配方,可应用于现场蝇类监测对比试验,进一步验证其对家蝇和其它监测蝇种的引诱效果。

Objective To investigate the luring effects of different formulae of fly baits, and to explore the commercialization and standardization of baits for fly monitoring. Methods Nine formulae of fly baits were prepared from jam, sweet bean sauce, brown sugar, milk powder, putrid fish paste, and fish meal at different ratios. The fly-luring effects of the fly baits were compared by cage trap method. Results Formula 5 （rotten fish paste＋sweet bean paste） had the highest trapping rate for Chrysomya megacephala, and formula 6 （rotten fish paste ＋ brown sugar ＋ milk powder） had the highest trapping rate for Musca domestica, as shown by the test which was performed at 3 rotations per month for 4-11 months. M. domestica accounted for 29.3% of all captured flies. The chi-square test revealed that formula 6 was significantly different from formulae 1-3 and 5, but without significant differences from formulae 4 and 7-9. The Student-Newman-Keuls test showed that formula 6 was better than other formulae, i.e., formula 6 〉 formulae 9, 7, 4, and 8〉formula 2〉formula 3〉formula 5〉formula 1. Conclusion Formula 6 is better than other formulas and thus can be used for field fly monitoring and comparison. Further investigation deserves to test its luring effects on M. domestica and other fly species.
