- 摘要:
- 针对人群聚集的坡地社区，南投县埔里镇爱兰国小校园、南投县埔里镇虎头山风景区、台中县潭子乡新兴“国小”校园、苗栗县新开“国小”与明德“国小”校园内不同小黑蚊栖地进行诱捕之研究。初步得知小黑蚊成虫为小群落，每群落雌小黑蚊数目鲜少超过20只，每群落危害空间小且离成虫栖地不远。坡地整治工程不良长期积水而孳生蓝绿藻处，该栖地小黑蚊下卵后经幼虫育成成虫已具飞行能力，成虫后栖地已移进接近人类活动栖所阴湿处、水生植物样区、或喜好的树下均为小黑蚊成虫最佳栖地之一。惟成虫前后栖地条件均易受天气与季节变化之影响而改变。尤其梅雨期如1993年与1994年。最近也收集到2004年“7.2”水灾之后三星期或2005年“6.12”水灾之后均已明显压抑小黑蚊成虫数目。
- Abstract:
- According to the numbers of Forcipomyia taiwana captured from sampled communities in slopeland including Ailan primary school campus and Hutoshan recreation area at Puli,Xinxing primary school campus at TanZi,and Xinkai and Minde primary school campus at Mianli county,the population of each F.taiwana school is as small as with female of less than 20 in most cases.Those habitats in which non-transient growth stages such as egg,larva,and pupa predominate at control structural faults appeared in the slopeland.The habitats of adult female close the habitats of human being.The spatial influence of female adults is short.The reduction of population happened in the rainy season of 1993 and 1994,post"7·2"flood in 2004,and post"6·12"flood in 2005 revealed the importance that valid features of adult or pre-adult habitat were suffered from weather conditions and seasonal changes.
