| 摘 要： | 在整粒小麦及半碎小麦中,黄色花蝽对杂拟谷盗的控制效果较好,但在小麦粉中无控制作用。在半碎小麦中,益害比1:20时,控制效果可达97.65％;在整粒小麦中,采用益害比1:1、1:2、1:4、1:8所得到的控制效果均无显著差异,但随着容器增大控制效果逐渐降低。

| Abstract: | Laboratory experimental results showed that Xylocoris sp. exerted effective Control on the population growth of the confused flour beetle, T. conf-usum in stored wheat grain, but not in wheat flour. When the" predator was introduced into the container at a predator:prey ratio of 1:20, the control effect was 97.65%. Yet no significant difference was found between the control effects at the predator:prey ratio of 1:1, 1:2, 1:4, or 1:8. The control effect reduced as the size of the containers increased. |
