A summary and analysis have been carried out on data from over 6000 instances of flystrike in sheep in NZ, over a 16-year period, using a self-referral system where farmers submitted larvae and related information. The study covered a period of establishment and subsequent countrywide spread of the exotic blowfly, Lucilia cuprina. Comparisons are drawn between flystrike as it was perceived by surveys carried out before the 1940s, and the current situation with L. cuprina as an added major impediment. Briefly, the main differences are an increase in the prevalence of flystrike, changes in the representation and relative influence of individual primary blowfly species, an extension of the flystrike 'season', and an apparent increase in the importance of footrot as a factor predisposing to flystrike. Otherwise, flystrike is still primarily a disease of ewe lambs that are struck predominantly around the tail and perineum, mainly because of faecal staining.
在16年的时间里，利用农民提交幼虫及相关信息的自我转诊系统，对新西兰6000多例绵羊蝇蛆病病例的数据进行了总结和分析。该研究涵盖了外来绿蝇（Lucilia cuprina）的建立及随后在全国范围内传播的时期。对20世纪40年代之前调查所认识到的蝇蛆病情况与当前绿蝇作为另一个主要障碍的现状进行了比较。简而言之，主要差异在于蝇蛆病患病率增加、个别主要丽蝇种类的表现和相对影响发生变化、蝇蛆病“季节”延长以及腐蹄病作为蝇蛆病诱发因素的重要性明显增加。此外，蝇蛆病仍然主要是母羊羔的疾病，主要发生在尾巴和会阴周围，主要原因是粪便污染。
