摘要
测定了烯啶虫胺亚致死剂量LC10与LC30胁迫12 h与24 h下,褐飞虱5龄若虫与成虫体内可溶性蛋白、糖类、甘油酯及游离氨基酸含量的变化。结果表明:LC30与LC10胁迫下的5龄若虫与胁迫12 h后的成虫体内可溶性糖的含量显著高于对照组;12 h胁迫下,LC30与LC10的烯啶虫胺均能提高5龄若虫与成虫体内游离氨基酸的含量,而24 h处理下的成虫体内游离氨基酸的含量显著低于对照;烯啶虫胺胁迫12 h后,褐飞虱成虫与若虫体内甘油酯的含量显著高于对照,而24 h处理下的5龄若虫体内甘油酯的含量显著低于对照;烯啶虫胺亚致死质量浓度胁迫下的褐飞虱5龄若虫与成虫体内蛋白质含量的变化趋势与游离氨基酸含量的变化有着相似之处。
We compared the changes of soluble sugar,glyceride,free amino acid and soluble protein contents in the 5th instar nymphs and adults of Nilaparvata lugens treated with sub-lethal doses of nitenpyram.The results indicated that the reserves of energy sources in nymphs and adults did have different variation trends.Soluble sugar contents in the 5th instar nymphs treated with LC10,LC30 stress in 12 h and 24 h and adults in 12 h stress were significantly higher than those 0f control;Glyceride contents in 5th instar nymphs and adults treated with LC10 stress were higher than those of control,but under 24 h stress,the glyceride content in the 5th instar nymphs was significantly lower than the control level;The variation trends of soluble protein contents in the 5th instar nymphs and adults were similar to that of free amino acid.The results suggested that under the control of sub-lethal doses of nitenpyram,the 5th instar nymphs and adults may have different coping mechanism and have important significance to understand the mechanism of sub-lethal doses of insecticide inducing resurgence of Nilaparvata lugens.
