1981—2000年,我们进行了麦长管蚜的调查研究。结果表明,麦长管蚜种群增长呈指数型Y=0.2673e~(0.193x);百株蚜量与有蚜株率的关系是指数型Y=5.4068e~(0.0864x)。并探讨了黑光灯下有翅麦长管蚜的高峰与田间蚜量突增的内涵关系。
From 1981 to 2000, we conducted a survey of wheat aphid. The results showed that the population growth of Aphis gossypii was exponential Y = 0.2673e ~ (0.193x). The relationship between the number of aphids per 100 aphids and the rate of the aphid was exponential Y = 5.4068e ~ (0.0864x). The relationship between the peak of Aphis gossypii and the amount of aphid in field was also discussed.
