本研究的目的是在生物学研究的基础上，确定在实验室中饲养头角圆蚧（Corcyra cephalonica, stanton, 1865）所需的适当饲料，以便为大规模生产赤眼蜂培育这种人造寄主。研究在25 +- 1℃，RH 60 +- 10%，光相14小时进行。比较了6种人工饲料：a)全麦面粉（48.5%）、大米（48.5%）和糖（3%）；B)大米（97%）和糖（3%）；C)全麦面粉（48.5%），米粉（48.5%）和糖（3%）；D)全麦面粉（97%）和酵母（3%）；E)小麦胚芽（97%）和酵母（3%）；F)米糠（94%），糖（3%）和酵母（3%）；F)米糠（94%），糖（3%）和酵母（3%）。尽管以小麦胚芽和酵母以及由米糠、糖和酵母组成的饲料被证明是最适合饲养这种蛾子的，但所有研究的饲料都允许头蛾的发育。这些饮食减少了总（卵-成虫）周期，缩短了产卵期，并产生了更重的成虫。繁殖生命表研究表明，饲喂这些饲料的成鱼具有较高的净繁殖率（Ro）和有限增重比（lambda）。
The objective of this research was, based on biological studies, to determine and adequate diet for rearing Corcyra cephalonica (Stainton, 1865) in the laboratory so as to permit the rearing of this factitious host for Trichogramma mass production. The research was conducted at 25 +- 1degreeC, RH 60 +- 10% and photophase of 14 hours. Six artificial diets were compared: a) whole wheat flour (48.5%), ground rice (48.5%) and sugar (3%); b) ground rice (97%) and sugar (3%); c) whole wheat flour (48.5%), rice flour (48.5%) an sugar (3%); d) whole wheat flour (97%) and yeast (3%); e) wheat germ (97%) and yeast (3%); f) rice bran (94%), sugar (3%) and yeast (3%); f) rice bran (94%), sugar (3%) and yeast (3%). All of the diets studied permitted the development of C. cephalonica although the diets with wheat germ and yeast and that consisting of rice bran, sugar and yeast proved to be the most adequate for rearing the moth. These diets reduced the total (egg-adult) cycle, shortened the egg laying period, and produced heavier adults. Studies on the fertility life tables showed that higher net reproduction rates (Ro) and finite ratio of increase (lambda) were obtained from adults reared on these diets.
