Abstract
The genetics of prescutellar bristles (prsc) in the melon fly, Bactrocera (Zeugodacus) cucurbitae (Coquillett) is polygenic with a quantitative trait of 1 to 20 prsc or more. The field population is polymorphic in regard of prsc and harbors 95% 2prsc phenotype (the major wild type) and 5% 4prsc phenotype (the minor wild type). 前期研究中已針對瓜實蠅Bactrocera cucurbitae (Coquillett)中胸背板之prescutellar bristles (prsc)數目屬數量遺傳(quantitative genetics)機制控制，惟在研究中發現野生型(wild type)之2PHT (2prsc phenotype; 2P-strain)與多剛毛品系(multiple prsc phenotypes; MB-strain)雜交時，F_1子代遵循數量遺傳法則，但F_2之頻度分布(phenotype frequency distribution)中，2PHT卻有異常增加之現象，可能有「非屬數量遺傳」之其他機制介入，因此本研究一方面確認前述觀察之確實性，另一方面則藉此探討其原因。
