METHODS: Mites were collected from sand fly larval rearing pots and morphologically identified using taxonomic keys. Upon identification, they were photographed with a scanning electron microscope. Several mite control measures were adopted in two different laboratories, one at the Laboratory of Malaria and Vector Research, National Institute of Allergy and Infectious Diseases-National Institutes of Health (Rockville, MD, USA), and the other at the University of Calgary (Calgary, AB, Canada).
RESULTS: The mite species associated with sand fly colonies in the two laboratories were morphologically identified as Tyrophagus sp. and Stratiolaelaps scimitus. While complete eradication of mites in sand fly colonies is considered unrealistic, drastically reducing their population has been associated with higher sand fly productivity.
CONCLUSIONS: We report a case of detrimental interaction between sand flies and Tyrophagus sp. and S. scimitus in a closed laboratory sand fly colony, discuss their impact on sand fly production and provide guidelines for limiting the mite population size in a closed laboratory colony leading to improved sand fly yields.
方法:从沙蝇幼虫饲养盆中收集螨,并使用分类学键进行形态鉴定。识别后,他们用扫描电子显微镜拍照。两个不同的实验室采取了几种防治螨的措施,一个在疟疾和病媒研究实验室,国家过敏和传染病研究所-国立卫生研究院(罗克维尔,MD,美国),另一个在卡尔加里大学(卡尔加里,AB,加拿大)。
结果:在两个实验室中与沙蝇菌落相关的螨物种在形态上被鉴定为Tyrophagussp。和Stratiolaelapsscimitus。虽然完全根除沙蝇群落中的螨虫被认为是不现实的,人口的急剧减少与更高的沙蝇生产力有关。
结论:我们报告了一例沙蝇和Tyrophagus之间的有害相互作用。和S.scimitus在一个封闭的实验室沙蝇殖民地,讨论它们对沙蝇生产的影响,并提供在封闭的实验室菌落中限制螨种群大小的指导方针,从而提高沙蝇的产量。
