摘要: The development and survival of nematode parasites sheep were studied in a cool tropical environment the highlands Ethiopia on 24 plots serially contaminated with Haemonchus contortus, Longistrongylus elongata Trichostrongylus colubriformis eggs over period 2 consecutive years from June 1993 to May 1995. availability infective larvae was monitored by monthly pasture sampling recovery. Infective recovered herbage collected June, July, August, September October both years. longevity varied between two six weeks when deposited October, respectively. During dry short rainy season (November through May), failed develop into L3 stage. It is suggested that long (7 8 months) lack trichostrongylid can be efficiently used strategic treatment programme interrupt transmission H. L. T. this environment.
