南瓜實蠅(Bactrocera tau (Walker))各蟲期之形態特徵在文中有詳細之描述及圖示。不同定溫下南瓜實蠅在洋香瓜上幼期發育所需時間隨溫度上升而縮短，卵於10℃下需時7.48天，35℃下僅需0.87天，幼蟲亦於10℃下需時最長為29.75天、30℃下則僅需8.23天，蛹於15℃下需時25.36天、30℃下僅需7.23天。卵、幼蟲及蛹之發育臨界低溫分別為9.13℃、2.39℃及10.25℃，有效積溫分別為16.41、267.59及142.15DD。成蟲壽命於15～25℃下超過6個月，30℃下雌蟲最長可活121天，雄蟲可活141天。成蟲之交尾於黃昏後至翌日清晨前之間進行，而於21:00時達到交尾高峰。平均每對成蟲交尾時間為584.59 ± 143.46分鐘(9.7 ± 2.4小時)。

The morphological characters of different stages of Bactrocera tau (Walker) are described in detail and illustrated in this paper. The developmental time of the immature stage of B. tau reared on muskmelon decreased with an increase in temperatures at seven tested constant temperatures of 10, 15, 20, 25, 28, 30 and 35℃. The developmental time for egg required 7.48 days at 10℃, while it took only 0.87 days at 35℃. In the larval stage, the developmental time was also the longest for 29.75 days at 10℃, while only 8.23 days were required at 30℃. The developmental time for pupae was 25.36 days at 15℃ and 7.23 days at 30℃. The theoretical low developmental threshold temperatures of eggs, larvae and pupae were 9.13, 2.39 and 10.25℃, and the thermal summations were 16.41, 267.59 and 142.15 DD, respectively. The longevity of adults was more than six months at 15～25℃, and the male and female could live 141 and 121 days, respectively, at 30℃. Adult mating began from dusk immediately after sunset to the following dawn with a mating peak at 21: 00. The averaged mating duration for each pair of adults ranged from 7.3 hours to 12.1 hours.
