脱皮8h内的粘虫6龄幼虫,用灭幼脲每头0.04μg胃毒处理后1d~4d,体内血糖和整体糖原含量高于对照约10%~20%左右,而血液和脂肪体内蛋白质含量则略低于对照,与此相反,处理5d后至初蛹期,粘虫体内血糖和整体糖原含量低于对照3%~20%,而血液和脂肪体内蛋白质含量却高于对照,7日龄时处理组幼虫脂肪体内蛋白质含量比对照高达31%。上述现象难以用灭幼脉抑制粘虫几丁质生物合成来解释,可能是其干扰了粘虫激素平衡的结果。同时,灭幼脲时稻瘟病菌孢子萌发有一定抑制作用,但抑制强度远低于异稻瘟净,说明灭幼麻可能对真菌几丁质合成有较弱的抑制。
The 6th instar larvae of the armyworm peeled within 8h of skin peeling showed that the content of blood glucose and whole glycogen in vivo were about 10% ~ 20% higher than that of the control after treatment with diflubenzuron 0.04μg stomach poisoning per head for 1d ~ 4d, while the blood and fat body On the contrary, the content of blood sugar and whole glycogen in the armyworm larvae were lower than that of the control by 5% ~ 20% after 5 days and the pupal stage, while the content of protein in blood and fat body was higher than the control, The protein content of fat body of 7-day-old larval treatment group was 31% higher than the control. The above phenomenon is difficult to explain by suppressing the offspring of the armyworm chitin biosynthesis, possibly as a result of its interference with the balance of armyworm hormones. At the same time, the spores germination of Magnaporthe grisea was inhibited when the germinant was treated with diflubenzuron, but the inhibitory strength was much lower than that of the different rice blast, which indicated that the weaker marijuana could inhibit the fungal chitin synthesis to a lesser extent.
