摘要

The sheep nose bot fly, Oestrus ovis L. (Diptera: Oestridae) is the causal agent of a very common cavitary myiasis affecting sheep and goat hosts worldwide. We reviewed the biology of the parasitic (feeding larvae) and free (non-feeding intrapuparialand adult) living phases as related to individual intrinsic and environmental factors. Temperature is the main environmental factor regulating the life cycle of this organism during both the parasitic and free phases. First-stage larvae are thought to beresponsible for monitoring environmental cues inside the host nasal passages. By contrast, second and third-stage larvae accumulate nutrient body reserves in order to support the intrapuparial and adult periods. Based on literature, this paper reports the first life table for an O. ovis population. Under natural conditions, the rate of population growth was 1.25 per generation, which indicates a great capacity of populations to recover from internal and external adverse factors. Interfering with waterand fat accumulation during the parasitic growth phase of this organism may be a promising new approach for designing control measures.
