| 摘 要： | 调查研究了新疆吐鲁番地区瓜套棉种植模式烟粉虱的时空动态,结果表明:瓜套棉田与单作棉花两种种植模式下烟粉虱在甜瓜和棉花寄主上的发生规律表现一致。套作甜瓜上的烟粉虱成虫的数量显著高于套作棉花和单作棉花,而套作棉花与单作棉花烟粉虱成虫数量动态和空间分布均差异不显著。瓜套棉与单作棉花烟粉虱成虫空间分布规律研究表明,在早晨8:00平均温度较低时(22℃),套作甜瓜、套作棉花和单作棉花烟粉虱成虫数量均表现出上部中部下部的分布特征,但在多数调查时间点未达到显著性差异水平。而中午14:00和黄昏19:00时平均温度较高(分别为32和28℃),两种种植模式下所有寄主的下部叶片烟粉虱成虫数量上升。两种种植模式下,无论是甜瓜寄主还是棉花寄主,烟粉虱若虫均以植株中部叶片数量最大。套作甜瓜若虫的空间分布规律为中部≥下部上部,而套作棉花和单作棉花若虫的空间分布规律均是中部上部≥下部。

| Abstract: | To investigate the relationship between numbers of the pregnant female in the 2nd generation and all individuals in the 3rd generation of brown planthopper (BPH), Nilaparvata lugens (St?l), field experiments were conducted with different number of pregnant female during June 20th to July 20th in Huizhou, Anhui Province. Results showed that (1) the number of pregnant female in the 2nd generation (x) determined the abundance of BPH in late season (y); (2) chemical control (chemical control: c=1; without chemical control: c=0)applied in the 2nd generation could suppress the population growth of BPH; and (3) these relationship could be modeled by an equation log(y)=0.943x -3.191 c+0.703xc+7.200. Based on this model, two threshold values of population size in the 2nd generation could be calculated, (1) the population in the 2nd generation must be suppressed with chemical control when x>0.4 individuals per 100 hills; and (2) the damage caused by BPH is unavoidable when x>2.4 individuals per 100 hills even if chemical control applied in the 2nd generation. The historical data during 2006-2014 also showed that BPH could be outbreak when the population size of BPH in the 2nd generation greater than 2.4 individuals per 100 hills. These results suggested that different control strategy could be selected to manage BPH according to the number of pregnant female. |
