摘要
目的 :查清热带珊瑚岛地里纤恙螨的生态分布 ,制定防制措施。方法 :用漂浮法采集具有代表性生境土壤里的地里纤恙螨成虫 ;笼日法捕小兽 ,收集地里纤恙螨幼虫。结果 :土壤里地里纤恙螨阳性率为 42 .2 %,恙螨平均数2 .8;小兽带螨率和带螨指数分别为 70 .0 %、82 .2 ;以黄胸鼠最高 ,分别为 98.0 %和 14 6 .8;生境以房舍周围的小兽带螨指数和土壤中恙螨数最高 ,分别为 99.8和 4.8。结论 :综合防制应抓住重点。
Objective: To study ecological distrbution of Leptotrombidium(L.) deliense in tropical coral island and make out prevent and control measurements. Methods:Collecting L. deliense adults from typical soil by floating method; collecting L. deliense larva from small animal traped by cage every day. Results: Positive rate of L. deliense in soil was 42.2%, The average was 2.8, ratio and index carried L. deliense with small animals were 70.0% and 82.2, Rattus flavipectus was high to 98.0% and 146.8. In terms of environment, L. deliense which was carried by small animal around house and soil was high 99.8 and 4.8. Conclusion: To prevent and control L. deliense in tropical coral islands should be to take important point.
