Abstract:

Objective To screen highly attractive formulations to Musca domestica under simulated field conditions in order to determine the optimal bait that can be commercialized for fly density monitoring. Methods Two different bait formulations were used on fly traps in a simulated field to compare their attraction effects. Results After two rounds of screening, SA-8 baits (50 g stale fish gel, 100 g brown sugar and 100 g water) were remarkably superior over other compounds considering the capture rate and cost-effectiveness; its capture rate (36.95%) was higher than that of sugar-vinegar baits (12.64%) with significant difference (χ²＝214.35, P＜0.01). Conclusion SA-8 could be subject to the field test as a candidate bait for further verification of its attraction effect on M. domestica and other fly species.

摘要：

目的 在模拟现场条件下筛选对家蝇引诱力强的配方，探索可商品化的用于蝇类密度监测的诱饵。方法 在模拟现场用捕蝇笼比较2种不同配方诱饵诱捕家蝇的差别。结果 通过2次筛选，从诱捕率和成本综合分析，SA-8 (腐鱼膏剂50 g＋红糖100 g＋水100 g)配方明显优于其他配方，其诱捕率(36.95%)高于糖醋诱饵的诱捕率(12.64%)，且二者差异有统计学意义(χ²＝ 214.35，P＜0.01)。结论 SA-8可作为候选诱饵，用于现场实验，进一步验证其对家蝇和其它蝇种的引诱效果。
