A field survey was undertaken between 1972-76 to reappraise the nature of the blowfly problem in New South Wales. For 2 years, 1972-1974, some 80,000 sheep were kept under observation and 12,481 strikes were reported, most due to Lucilia cuprina. Breech strike was still the basic problem but tail strike associated with scouring had become an important component where pastures have been improved. Breech strike was controlled at minimal cost by managerial practices such as docking tails the correct length--second joint-space palpable ventrally (midway down the vulval orifice in ewes) for radically mulesed lambs and the third joint-space (tip of vulva in ewes) for all other lambs-mulesing at lamb marking, mid-season crutching, determining the cause of scouring and applying the appropriate preventative or remedial measures. Thus the use of insecticides could be reserved for the control of body strike in young sheep in the odd wet years and poll strike in horned rams. Major outbreaks of body strike occurred in 1973/74. Body strike worried graziers most because of its unpredictability, sudden onset and scale. and only failing insecticides were available for control.
1972年至1976年间进行了一项实地调查，以重新评估新南威尔士州绿头苍蝇问题的本质。在1972年至1974年的两年间，约80,000只绵羊被置于观察之下，报告了12,481次羊蝇叮咬，其中大部分是由铜绿蝇引起的。臀部蝇蛆病仍然是主要问题，但与腹泻相关的尾部蝇蛆病在牧场得到改善的地方已成为一个重要组成部分。通过一些管理措施，如将尾巴剪到正确的长度（对于彻底进行剪毛的羔羊，剪到腹侧可触及第二关节间隙处，即母羊外阴孔的中部；对于所有其他羔羊，剪到第三关节间隙处，即母羊外阴的尖端），在羔羊打号时进行剪毛，在季节中期进行腹毛清理，确定腹泻原因并采取适当的预防或补救措施，以最低成本控制臀部蝇蛆病。因此，杀虫剂可留作在偶尔潮湿年份控制幼羊的体部蝇蛆病和有角公羊的头部蝇蛆病。1973/74年发生了大规模的体部蝇蛆病疫情。体部蝇蛆病最令牧场主担忧，因为它不可预测、突然爆发且规模较大，而且当时只有效果不佳的杀虫剂可用于防治。
