由于甘蔗种苗调运和施肥水平的提高等原因 ,甘蔗粉蚧在我省各蔗区为害逐年加重 ,为了掌握其发生规律 ,正确估计田间种群数量 ,提高抽样调查精确度 ,为预测预报及防治提供科学依据 ,我们于 1 998年开展了甘蔗粉红粉蚧空间分布及取样技术研究 ,现将结果整理如下 :1 甘蔗粉红粉蚧
Due to such factors as the transportation and fertilization level of sugarcane seedlings, the mealybugs mealybug multiply in every sugarcane area in our province. In order to grasp the regularity of their occurrence, the correct estimation of the population quantity in the field and the improvement of the accuracy of sampling survey are provided for forecasting and prevention Scientific basis, we carried out in 1998 the sugarcane pink mealybug spatial distribution and sampling techniques, the results are summarized as follows: 1 sugarcane pink mealybug
