The largest and most precious Chinese butterfly Troides helena spilotia Rothschild is occurring all year round with overlapping 6 generations in Hainan Jianfengling forest each year. The appropriate growth temperature for it is 25－30 ℃, and the humidity is 70%－80%. Large-scale artificial breeding of Troides helena spilotia Rothschild need to comply with the requirements of their breeding rooms by planting host plants for their eggs. Dilution of the concentration of honey and water is 10%－15% in summer and 5% in winter; the eggs should be moisturizing when collecting indoor and outdoor. The larvae should be transferred to the host plants planted in the field with net bags; and transfer them to different host plants timely according to their instars and food intake; the indoor population density should be controlled. Due to the 4－5 instars larvae will ingest a great deal of food, they need to be fed 3 times a day in the morning, afternoon and the evening. The ways to suspend the pupa when feeding indoor and outdoor vary according to the breeding facilities. The pupa should be collected and put in the emergence room and hung them up according to their natural shape. The suitable temperature for it is 25－28 ℃, and humidity is 60%－80%. 相似文献

以红厚壳（Calophyllum inophyllum）1年生嫩枝为扦插材料,探讨不同浓度梯度的萘乙酸（NAA）、吲哚丁酸（IBA）及生根粉1号（ABT）对插穗抽叶特性和生根特性的影响,并运用隶属函数值法对各处理组合的扦插效果进行综合评价。结果表明：与对照处理相比,不同激素种类及浓度处理显著影响嫩枝插穗的抽叶率、新叶数量、新叶面积等抽叶特性指标,以及生根率、偏根率、不定根数量、不定根体积、侧根数量和侧根长度等生根特性指标,但对宿叶率影响不显著。不同激素处理下嫩枝插穗的抽叶率和生根率分别为21.7%~66.7%和43.3%~98.3%,而对照处理的抽叶率和生根率均为0。基于隶属函数值法综合分析,激素处理对扦插效果的促进作用依次为NAA>ABT>IBA。NAA处理插穗的抽叶率和生根率均值为62.1%和95.4%,分别比ABT处理增加47.5%和30.2%,比IBA处理增加62.0%和57.9%。综合分析,红厚壳嫩枝扦插的最佳处理组合为1000 mg/L NAA,其抽叶率为61.7%,生根率为95.0%。 相似文献
