中文摘要: |
黏虫Mythimna separata Walker是一种世界性害虫。为了明确不同寄主植物对黏虫幼虫体内能源物质的影响, 选取了玉米、小麦、燕麦、老芒麦4种黏虫的禾本科寄主植物对黏虫进行饲喂, 并测定黏虫3、4、5龄期幼虫体内的可溶性蛋白、可溶性糖及甘油酯的含量; 测定了4种寄主植物粗蛋白及粗纤维的含量, 并与黏虫能源物质含量进行了相关性分析。结果表明, 喂食燕麦的黏虫体内可溶性蛋白含量达到263.84 μg/mg, 显著高于其他3种植物(P<0.05); 喂食4种植物黏虫体内甘油酯含量为106.69~152.23 μg/mg, 没有显著差异(P>0.05); 喂食玉米的黏虫体内可溶性糖含量为68.64 μg/mg, 显著低于其他3种植物(P<0.05)。寄主植物粗蛋白含量与黏虫体内能源物质含量均呈正相关关系, 寄主植物粗纤维含量与黏虫体内能源物质含量均呈负相关关系。说明不同寄主对黏虫幼虫体内能源物质有显著影响, 且与饲喂的寄主植物所含物质含量具有显著的相关性。 |
英文摘要: |
Mythimna separata Walker is a worldwide pest. In order to determine the effects of different host plants on the energy substances in the larvae, four Gramineae host plants of maize, wheat, oat and siberian wildrye grass were selected to feed the insects. The contents of soluble protein, soluble sugar and glyceride in the larvae of 3rd, 4th and 5th instar were determined; the content of crude protein and crude fiber in 4 host plants were determined, and the correlation analysis was also performed with the content of the energy materials in M. separata. The results showed that the content of soluble protein in M. separata fed with oat was 263.84 μg/mg, significantly higher than that of the other three host plants (P<0.05), but the content of glycerin in M. separata fed with the four plants was 106.69-152.23 μg/mg, without significant difference (P>0.05). The soluble sugar content was 68.64 μg/mg in M. separata fed with corn, significantly lower than that fed with the other three plants (P<0.05). There was a positive correlation between crude protein content in the host plant and energy content in M. separata, and a negative correlation between the crude fiber content in the host plant and the energy in M. separata. |
