摘要
通过室内单头饲养小贯小绿叶蝉,观察了其蜕皮、羽化及孵化的时间规律.结果表明,1龄若虫蜕皮时间为(4.83±0.13)min,2龄若虫为(5.14±0.13)min,3龄若虫为(5.07±0.11)min,4龄若虫为(5.64±0.17)min;1、2龄若虫蜕皮数量在24 h内分布比较均匀,3龄若虫蜕皮时间集中在2:00-4:00,4龄若虫多在4:00-7:00和16:00-19:00蜕皮.雌虫羽化时蜕皮过程持续(8.15±0.18)min,雄虫持续(8.02±0.21)min;雌虫整个羽化过程需要(16.82±0.27)min,雄虫需要(16.15±0.29)min,雌雄虫间无显著差异;雌雄虫羽化高峰分别在5:00-12:00和4:00-11:00.卵孵化持续时间为(7.42±0.52)min,孵化的高峰出现在5:00-8:00.
The rhythms of molting, eclosion and hatching of tea green leafhopper were studied through raising and monitoring tea green leafhopper individually. Results showed that molting durations of 1-4 instars nymphs were (4.83±0.13), (5.14±0.13), (5.07±0.11) and (5.64±0.17) min, respectively. When it comes to molting for 1-2 instar, it occurred relatively evenly during 24 h while a high molting frequency was observed during 2:00-4:00 for 3-instar nymphs and during 4:00-7:00 and 16:00-19:00 for 4-instar nymphs. Durations of the last molt, as the forepart of eclosion, no significant difference occurred between female and male, which were (8.15±0.18) and (8.02±0.21) min, respectively. Then it took female (16.82±0.27) min and male (16.15± 0.29) min to complete eclosion without significant difference neither. Both female and male showed daily eclosion peaked from 5:00-12:00 and 4:00-11:00, respectively. And egg hatching lasted for (7.42±0.52) min and peaked from 5:00 to 8:00 once a day.
