摘要
研究表明,酵母粉、黄豆粉和维生素C是棉铃虫生长发育的必需成分;仅用醋酸即可达到防腐的目的。本研究确定生物测定感染饲料配方为:黄豆粉7g、酵母粉4g、维生素CO.5g、36％醋酸1.25ml、琼脂1.5g,水100ml.醋酸用量占饲料重量的1～1.5％为宜。
The results of the investigation indicate that yeast flour, soybean flour and ascorbic acid are indispsnsable for the development of cotton bollworm larvae. Using acetic acid alone can prevent diet from contamination by microbes. The ingredients of the diet are as follow, soybean flour 7g, yeast flour 4g, ascorbic acid 0.5g, 36%-acetic acid 1.25ml, agar 1.5g, water 100ml.
