中文摘要:
【目的】 为评价一种红棕象甲Rhynchophorus ferrugineus Oliver人工饲料的饲养效果。【方法】 以自然寄主大王棕和甘蔗饲养红棕象甲作对照,连续3代饲养红棕象甲,对红棕象甲各发育阶段的生长和发育指标进行调查。【结果】 用人工饲料饲养的红棕象甲幼虫历期和蛹历期(40.20 d和33.99 d)显著低于对照组(60.87 d和36.12 d;109.00 d和42.70 d),用人工饲料饲养的红棕象甲幼虫存活率(63.87%)显著高于对照组(37.99%和48.60%)。人工饲料饲养的红棕象甲,在单雌产卵量和卵孵化率方面与对照组没有显著差异,在蛹重和成虫体重方面显著小于对照组,蛹重比对照组减少了25.55%和63.87%,成虫体重比对照组减少了24.18%和35.16%。【结论】 该人工饲料可以很好的满足红棕象甲生殖发育的营养需求,且缩短了世代发育历期,适于红棕象甲种群规模化、长期饲养。
英文摘要:
[Objectives] The establishment of insect colonies under artificial conditions is important for research and the development of a set of artificial diets suitable for a variety of insect species can greatly decrease costs and improve the efficiency of maintaining such colonies. [Methods] A diet was developed using two rounds of orthogonal design methods and employed successfully in rearing three Noctuoidea species: Hyphantria cunea (Drury), Prodenia litura (Fabricius) and Lymantria dispar (L.). [Results] The diet contained wheat germ (12%), sugar (2%), casein (4.5%), agar (1.5%), choline chloride (0.05%), Wesson’s salt (1.0%), sorbic acid (0.4%), methyl p-hydroxybenzoate (0.25%), ascorbic acid (0.5%), Vanderzant’s vitamin mix (0.003%),cholesterol (0.1%) and inositol (0.035%). [Conclusion] The three insect species reared on this diet displayed normal larval development, pupal weight, pupation and eclosion rates. This research will provide a basis for the development of artificial diets for other polyphagous insects.
