中文摘要 | 利用含毒克蠅(poisoned cuelure)於全臺18縣市31個調查點進行南瓜實蠅之分布及豐度調查,結果顯示南瓜實蠅主要分布於臺中以北之北部地區及東部花蓮地區,臺灣西南部及南部之平原地區則較少發生甚或無其分布。在垂直分布上,沿中橫臺14甲線作不同海拔高度調查時發現,山區高海拔地區乃至2,161公尺之翠峰均有南瓜實蠅之普遍分布。因南瓜實蠅與瓜實蠅之生態棲位甚為相近,故在調查時將瓜實蠅一併列入記錄,以進行比較。南瓜實蠅在臺灣各地區之發生與瓜實蠅相較時其所佔數量比例,僅於石碇、關西及花蓮市以及海拔600公尺以上之地區,南瓜實蠅發生數量比例高於瓜實蠅。就南瓜實蠅於各地區分布之豐度而言,一般皆較瓜實蠅為低,唯兩者發生相對豐度較高地區各有不同,南瓜實蠅以臺灣中部以北之北部地區及花蓮地區豐度較高,尤以新城全年誘得3,472隻為最高,山區之分布及豐度亦較平地為高,而瓜實蠅豐度較高之地區則集中於西南部平原地區。 |
英文摘要 | In this study, the distribution and abundance of Bactrocera tau was surveyed by using poisoned cue-lure traps at 31 investigating sites covering the entire island of Taiwan in 2001-2002. It showed that B. tau was distributed mainly in the northern part of Taiwan as well as the Hualien area, although there was also a relatively scattered distribution found in the southern part of Taiwan including the southwestern plain. For the vertical distribution of this species, 11 additional investigating areas were surveyed along Taiwan Highway No.14a at different elevations. It showed that B. tau was generally distributed in the mountain area, even at the 2,161 m high elevation. Since the ecological niche of B. tau is very similar to that of B. cucurbitae, the numbers of B. cucurbitae collected in periodic surveys were recorded and compared with B. tau. When comparing the ratios in which the fly populations occurred in different areas, it was found that there was a higher ratio of B. tau than B. cucurbitae in a few areas of Shi Ding, Quan Si, Hualien city in northern Taiwan and in the mountain areas above the 600 m elevation. On the other hand, the abundance of B. cucurbitae was higher in most of the plain areas of Taiwan. However, the areas where either of these two species showed a higher abundance differed substantially. B. tau was more abundant in the northern areas of Taiwan, while B. cucurbitae showed a higher abundance in the southern areas. |
