摘要：利用蔗糖辅助培育胭脂虫,设置10个不同水平蔗糖浓度,每个水平10组重复,研究不同浓度蔗糖对胭脂虫的助食作用。结果表明:蔗糖对胭脂虫有明显助食作用,适当浓度的蔗糖有助于提高胭脂虫的产量。蔗糖浓度47.5 g·L-1至475.0 g·L-1可提高上虫量;在285.0 g·L-1浓度下,胭脂虫的存活率较高,种群数量变动较小;47.5 g·L-1至380.0 g·L-1均有利于提高雌成虫数量,并明显提高胭脂虫单片茎片的鲜质量和干质量;不同浓度的蔗糖均可提高胭脂虫雌成虫的体积及怀卵量,285.0 g·L-1浓度的蔗糖辅助培育胭脂虫效果最明显。
A study on feeding effect of different sucrose levels on cochineal was carried out. The sucrose was pw- pared in 10 concentration levels （0.0, 47.5, 95.0, 190.0, 237.5, 285.0, 380.0,475.0, 617.5, and 712.5 g ·L-1 ） and 10 samples were repeated on each level. The results showed that the feeding effect of sucrose on cochi- neal insect was very obvious, and the appropriate concentration of sucrose would be helpful to improve cochineal yield. With the concentration ranged from 47.5 g·L-1 to 475.0 g ·L-1, the sucrose increased the larva quantity on cacti ; with the concentration of 285.0 g·L-1, the survival rate of cochineal was quite high and population was stable; the concentration of 47.5 g·L-1 to 380.0 g ·L-1 could increase the number of female aduh, the fresh weight and dry weight of cochineal. In addition, all the sucrose concentration levels could improve the amount of eggs and enlarge female adults. It is showed that 285.0 g ·L-1 sucrose level is most helpful to feed cochineal.
