Abstract

本发明涉及一种小菜蛾幼虫人工饲料及其制备方法,由各组分按一定比例配制。所述小菜蛾幼虫人工饲料各组分及其重量百分比为:甘蓝粉6-8%;酵母粉3-5%;玉米粉6-8%;维生素C 0.3-0.5%;琼脂粉1-3%;山梨酸0.1-0.3%;蒸馏水为余量。本发明为小菜蛾幼虫的规模化饲养提供了必备的条件;为农药药效检测结果的准确性提供了技术保证;减轻了用自然饲料饲养时的污染问题;降低了消毒灭菌处理养虫室的能源消耗;为小菜蛾病毒生产提供了可控的无菌饲料。

Description

一种小菜蛾幼虫人工饲料及其制备方法
技术领域
本发明涉及一种昆虫的人工饲料,特别是指一种小菜蛾幼虫人工饲料及其制备方法。
背景技术
小菜蛾是全世界十字花科蔬菜的重要害虫之一,据上世纪九十年代资料报道,全世界每年用于防治小菜蛾的费用高达10亿美元,仅美国每年就耗资1亿美元。
小菜蛾具有繁殖力强、生活周期短、世代交替和适应性强等生物学和生态学特性,并以其对农药的抗药性发展快,抗性强,导致化学农药防治难度大,致使化学防治过程中,农药的使用浓度和用药频繁不断提高,形成了“农药-抗性-农药”道高一尺,魔高一丈的不断提高的恶性循环,而成为当今蔬菜的一大害虫。
全世界农药企业都在研究防治它的技术措施。根据环保和食品安全的需要,现在研究低毒、低残留的化学农药及生物农药,如苏云金杆菌、球型芽孢杆菌和小菜蛾病毒等的这些企业,都离不开小菜蛾幼虫的饲养技术。人工饲养繁殖小菜蛾幼虫是一条重要途径。现在常用的方法是叶菜饲养和菜籽培养盘饲养幼虫,虽然能解决部分虫源,但不能形成规模化和工业化生产,因此小菜蛾人工饲料的配方及配制方法就成了小菜蛾饲养规模化或产业化的必备条件。
发明内容
有鉴于此,本发明的目的在于提供一种小菜蛾幼虫人工饲料及其制备方法。该方法为小菜蛾幼虫的规模化饲养提供了必备的条件。
为达到上述目的,本发明提供一种小菜蛾幼虫人工饲料,所述小菜蛾幼虫人工饲料各组分及其重量百分比为:
甘蓝粉        6-8%;
酵母粉        3-5%;
玉米粉        6-8%;
维生素C       0.3-0.5%;
琼脂粉        1-3%;
山梨酸        0.1-0.3%;
蒸馏水        余量。
本发明提供一种小菜蛾幼虫人工饲料的制备方法,所述小菜蛾幼虫人工饲料按下列步骤配制:1)根据配方称量好各组分;2)然后取蒸馏水总量五分之三及甘蓝粉、酵母粉、玉米粉加入不锈钢容器中,加温至100℃煮开,搅拌均匀得一混合液;3)取蒸馏水总量五分之二及琼脂粉、山梨酸加入不锈钢容器中,加温至100℃煮开,搅拌均匀得另一混合液;4)然后将步骤2)和3)所得的混合液分别加入维生素C中,搅拌至均匀;5)用养虫杯分装密封,放入4℃冰箱内,冷藏备用。
作为优选方案,其中所述甘蓝粉为鲜品烘干,磨碎,过80目筛,用筛下干粉。
本发明具有以下有益效果:
本发明为小菜蛾幼虫的规模化饲养提供了必备的条件;为农药药效检测结果的准确性提供了技术保证;减轻了用自然饲料饲养时的污染问题;降低了消毒灭菌处理养虫室的能源消耗;为小菜蛾病毒生产提供了可控的无菌饲料。
具体实施方式
下面结合具体实施例对本发明进一步描述。
小菜蛾人工饲料配力如表1、表2所示。
表1:小菜蛾人工饲料配方1
Figure BSA00000421066400021
表2:小菜蛾人工饲料配方2
所述人工养殖小菜蛾幼虫饲料按下列步骤配制:1)根据配方称量好各组分;2)然后取蒸馏水总量五分之三及甘蓝粉、酵母粉、玉米粉加入不锈钢容器中,加温至100℃煮开,搅拌均匀得一混合液;3)取蒸馏水总量五分之二及琼脂粉、山梨酸加入不锈钢容器中,加温至100℃煮开,搅拌均匀得另一混合液;4)然后将步骤2)和3)所得的混合液分别加入维生素C中,搅拌至均匀;5)用养虫杯分装密封,放入4℃冰箱内,冷藏备用。
所述甘蓝粉为鲜品烘干,磨碎,过80目筛,用筛下干粉。
表3:小菜蛾人工饲料配方与天然饲料、萝卜苗饲养效果对比表
Figure BSA00000421066400032
从表3中可以看出,在供试虫数相同情况下,小菜蛾人工饲料配方1和配方2的产卵量及孵化数略低于天然饲料(白菜)和萝卜苗,即其饲养效果略低于天然饲料(白菜)和萝卜苗。但小菜蛾人工饲料配方操作简单,容易控制,为小菜蛾幼虫的规模化饲养提供了必备的条件。
以上仅为本发明所列举的较佳实施例,并非用以限制本发明的保护范围,所属技术领域中的普通技术人员运用本发明所作的等效修饰或变化,均同理应属于本发明的专利保护范围。
