Monitoring and collection of fly taxa (Diptera: Calliphoridae; Muscidae; Sarcophagidae) of medical, veterinary, and agricultural importance is often routine practice, providing data on target species presence, distribution and abundance. Collection practices currently involve baited trapping and while an inherent bias accompanying the choice of bait is acknowledged, there is little consistency in bait choice between studies and insufficient assessment of trapping success rates for bait types in current use. This study aimed to examine the effect of bait choice on trapping results for six commonly used bait types; a commercial bait (Envirosafe Fly Attractant, Envirosafe Products) and a combination of mixtures of liver, horse manure and 5% sodium sulfide (Na2S). Trapping success was compared under different seasonal conditions (Summer, Autumn, and Spring) to determine the most attractive bait for calliphorid species, with a secondary comparison of kangaroo versus ox liver occurring under summer conditions. Baits containing Na2S were the most successful in captures of all target taxa, with the addition of manure desirable, yielding increased diversity of taxa. Kangaroo liver baits attracted high numbers of Chrysomya spp. (Robineau-Desvoidy, Diptera: Calliphoridae), while Lucilia spp. (Robineau-Desvoidy, Diptera: Calliphoridae) were comparatively underrepresented in traps using liver alone. The use of a combined ox liver/manure/Na2S bait is recommended as the gold standard for generic screening of necrophagous flies. Where more specific target fly taxa are desired, such as Chrysomya spp. or Lucilia spp. only, alternate baits such as kangaroo or lamb may prove more attractive/successful.
监测和收集具有医学、兽医和农业重要性的蝇类分类群（双翅目：Calliphoridae；Muscidae；Sarcophagidae）通常是常规做法，可提供目标物种存在、分布和丰度的数据。收集方法目前涉及诱捕，尽管诱饵选择所伴随的固有偏见得到了承认，但不同研究之间的诱饵选择一致性较差，并且对当前使用的诱饵类型的诱捕成功率评估不足。本研究旨在检查诱饵选择对六种常用诱饵类型的诱捕结果的影响；一种商业诱饵（Envirosafe Fly Attractant，Envirosafe Products）和混合肝脏、马粪和 5% 硫化钠（Na2S）的混合物。在不同的季节性条件（夏季、秋季和春季）下比较了诱捕成功率，以确定对Calliphorid 物种最具吸引力的诱饵，并且在夏季条件下还比较了袋鼠和牛肝的差异。含有 Na2S 的诱饵在捕获所有目标分类群方面最成功，添加粪便更可取，可增加分类群的多样性。袋鼠肝脏诱饵吸引了大量 Chrysomya spp.（Robineau-Desvoidy，双翅目：Calliphoridae），而单独使用肝脏诱饵时，Lucilia spp.（Robineau-Desvoidy，双翅目：Calliphoridae）的捕获量相对较少。建议使用牛肝/粪便/Na2S 混合诱饵作为通用腐生性蝇类筛选的金标准。如果需要更具体的目标蝇类分类群，例如 Chrysomya spp.或 Lucilia spp.，则可以使用袋鼠或羔羊等替代诱饵，它们可能更具吸引力/更成功。
