| 摘 要： | 嗜卷书虱是我国粮食储藏常见害虫,但因其食性广、孤雌生殖方式、磷化氢抗性等原因治理难度大,本实验探究机械通风对粮堆内嗜卷书虱种群的影响。研究发现,机械通风对粮堆内嗜卷书虱具有较好的防治效果,其死亡率随着通风时间的增加可达100%。嗜卷书虱死亡率随着机械通风时单位面积通风量的增加而增加,且成线性相关:0. 033 m/s单位面积通风量时,函数关系为:y=8. 222 6x+9. 610 7; 0. 048 m/s单位面积通风量时,函数关系为:y=8. 564 9x+36. 364; 0. 062 m/s单位面积通风量时,函数关系为:y=4. 890 5x+56. 843。

Research on the effect of control on Liposcelis bostrychophilus by mechanical ventilation in small grain bulks |

| Abstract: | Liposcelis bostrychophilus is a common pest of grain storage in China, but it is difficult to control due to the wide range of food, parthenogenesis, phosphine resistance ,etc. This experiment research the effect of control on Liposcelis bostrychophilus by mechanical ventilation in small grain bulks. The experiment found that mechanical ventilation have good control effect on the Liposcelis bostrychophilus in the small grain bulk, the mortality rate could reach to 100% with the prolongation of ventilation time . Linear positive correlation was found between the mortality rate of Liposcelis bostrychophilus and the ventilation speed of per unit area. If the ventilation speed of per unit area was 0.033 m/s, 0.048 m/s, 0.062 m/s, respectively, the function relationship would be y = 8.222 6x + 9.6107,y = 8.564 9x + 36.364 , y = 4.890 5x + 56.843. |
