Sanitation has been long recommended as a means of reducing stable fly, Stomoxys calcitrans (L.), populations at cattle feedlots, but there is little published research to support this recommendation. In each of the 2 yr of this study, 4 feedlots received complete sanitation and 4 feedlots received no cleaning. The objective was to have the initial cleaning done before 1 June and then to reclean as needed every 2 wk thereafter. The feedlots that were cleaned had significantly fewer flies than the uncleaned feedlots, with 50.9% fewer stable flies during the 1st yr and 36.2% fewer flies in the 2nd yr. These reductions were realized even though initial cleaning was not done by 1 June in either year: bad weather delayed completion until 20 June the 1st yr and 29 June the 2nd yr. Sanitation at cattle feedlots significantly reduces stable fly populations and sanitation may have been more effective if initial cleaning was done by 1 June.
长期以来,人们一直推荐通过卫生措施来减少肉牛饲养场厩螫蝇(Stomoxys calcitrans (L.))的数量,但鲜有已发表的研究来支持这一建议。在本研究的两年中,每年有4个饲养场进行全面卫生清理,另外4个饲养场不进行清理。目标是在6月1日前完成初次清理,之后根据需要每两周重新清理一次。进行清理的饲养场的苍蝇数量明显少于未清理的饲养场,第一年厩螫蝇数量减少了50.9%,第二年减少了36.2%。尽管两年中均未在6月1日前完成初次清理(第一年因恶劣天气延迟至6月20日完成,第二年延迟至6月29日完成),但仍实现了这些减少。肉牛饲养场的卫生措施能显著减少厩螫蝇数量,如果在6月1日前完成初次清理,卫生措施可能会更有效。
