中文摘要 | 南瓜實蠅(Bactrocera tau(walker))幼蟲,以木瓜個別飼育,置於25±1℃、70±5% RH,光週期12L:12D下,觀察各蟲期發育所需的時間,結果如下:卵期平均為0.97日,幼蟲期5-14日,平均為8.63日,蛹期5-13日,平均為8.6日;卵孵化至成蟲羽化所需時間為15-23日,平均發育期為18.45日,其存活率為62%。雌、雄比為1:1。雌、雄蟲每日羽化時刻集中分布於4:00-14:00之間,但以早上6:00-10:00羽化數量最多。雌成蟲羽化後9天,開始可與雄蟲交尾,最長者18天,平均14.7±0.3天,而雄成蟲平均為14.3±0.2天,最短者10天,最長者需18天。交尾時刻集中分布於17:30-22:00,其交尾高峰在18:30-19:00,而其交尾持續時間,由20-800 min不等,平均504.8±62.5 min,約8.4 hr。產卵持續時間,自產卵管插入至拔出時間,平均3.18 min.。在花蓮新城自1992年9月至1996年5月田間調查,以含毒甲基丁香油和克蠅誘殺器誘殺南瓜實蠅雄成蟲,每月平均的誘殺蟲數全年有二次發生盛期,第一次於5-7月,高峰在6月,第二次在11-1月,高峰在12月,且整年皆有發生。 |
英文摘要 | Pumpkin fly (Bactrocera tau (Walker)) larvae were fed on papaya and reared in growth chamber at 25 ± 1℃ and 70 ± 5% RH, with a 12L : 12D photoperiod for observation of time requirement in different developmental stages. The results showed it was 0.97 day for eggs; 5-14 days, average 8.95days for larvae; 5-13 days, average 8.63 days for pupae. The developmental duration from egg to adult was 18.45 days in average. The female to male ratio was 1:1. Adults emerged from 4:00 to 14:00, while the emergence peak took place at 6:00-9:00 each day. The mean pre-copulatory period was 14.7 ± 0.3 days for the female, 14.3 ± 0.2 days for the male flies. The copulatory and oviposition behaviors of the pumpkin fly were directly observed. When one female was paired to a male, more mating schedules took place from 17:30 to 22:00. The peak of mating occurred between 18:30 to 19:00 daily. The averaged mating duration for each pair of adults was 504 min While the duration of oviposition was 3.18 min in average. From September, 1992 to May, 1996, the field occurrence of pumpkin fly was investigated monthly, by using poisoned methyl eugenol and cuelure in Hualien. There were two peaks of pumpkin fly population in a year, the first peak appeared in June, while the second peak was in December. The pumpkin fly can be found all the year round in Hualien. |
