摘要
目的比较分析腐烂鱼肠鱼鳃、红糖食醋以及腐败鸡蛋3种诱饵对不同蝇种的引诱力差别,以筛选媒介蝇类监测的最佳诱饵。方法采用诱蝇笼法,选取5个实验点同时使用3种饵料进行诱集,诱得的蝇类在实验室进行鉴定。结果 3种诱饵诱集的蝇种区别不明显,诱集个体数量上按多少排列依次为腐烂鱼肠鱼鳃饵、腐败鸡蛋饵、红糖食醋饵,分别占捕蝇总数的66.99%、32.07%和0.94%;不同诱饵诱集的优势种差别较大,腐烂鱼肠鱼鳃饵诱集的优势种为大头金蝇和家蝇,红糖食醋饵为铜绿蝇,腐败鸡蛋饵为大头金蝇和瘦叶带绿蝇;丽蝇科和蝇科趋向于被腐烂鱼肠鱼鳃饵吸引,而丽蝇科、麻蝇科和花蝇科更喜好腐败鸡蛋饵。结论红糖食醋饵诱集数量过少,难以反映季节变化;腐烂鱼肠鱼鳃饵诱集少数种类个体数量过多而掩盖了其它种类的真实密度;腐败鸡蛋饵诱集数量适中,种类较均衡,可以作为蝇类监测用饵料。
Objective To compare the efficacy of three kinds of baits （rotten fish, rotten eggs and brown sugar-vinegar） against flies to offer the ideal option for vector monitoring. Methods Fly traps with different baits were deployed simultaneously in five experimental sites. The captured flies were identified in the laboratory. Results No significant differences in the captured species was found between the baits. Flies captured by the rotten fish, rotten eggs and brown sugar-vinegar accounted for 66.99%, 32.07% and 0.94%, respectively. Chrysomya megacephala and Musca domestica were the dominant species in the rotten fish group. Lucilia cuprina was more easily attracted by sugar-vinegar baits. Rotten eggs were more attractive to C. megacephala and HemipyreUia ligurriens. Calliphoridae and Muscidae were more easily attracted by rotten fish, while Sarcophagidae, Calliphoridae and Anthomyiidae preferred rotten eggs. Conclusion Sugar-vinegar baits did not reflect seasonal changes as they attracted a very small number of flies. Rotten fish attracted a large number of flies from only a few species. Rotten eggs could attract a proper number of flies from a balanced collection of species, and thus could be used for fly monitoring.
