摘要: Two climate chamber experiments were conducted to determine the effect of varying initial soil moisture (0, 10 and 15%), simulated rainfall amount 12 24 mm) timing (days -1, 0 3 relative faecal deposition) on development (day 14) Haemonchus contortus Trichostrongylus colubriformis third stage larvae (L3) (FM). Increasing content from or 15% led higher recovery total L3 (P<0.001). Total increased with each level (P<0.001) in ascending order 0, mm. There was an interaction between effects L3, showing that benefit lessened increasing moisture. Simulated day deposition resulted than other days. FM best associated H. T. (R(2)=0.32-0.46), reinforcing importance sufficient soon after deposition. The moisture, largely explained by changes values within 4 days These results highlight influence its L3. Consequently we recommend be given greater definition conduct ecological studies parasitic nematodes, improve predictions
