黄板诱杀是防治菇蚊蝇的常见措施。为探索平菇(Pleurotus ostreatus)菇房中,黄板悬挂位置与高度对眼蕈蚊(sciarid flies)成虫诱杀效果的影响,本试验选取日光温室型平菇菇房,在成虫盛发期,先后设置双风口和单风口两种通风模式,调查了棚室内北、中、南3个方位及其1、1.5、2、2.5 m等不同悬挂高度的黄板诱杀眼蕈蚊的数量,并分析了诱虫数量与悬挂位置的照度值之间的关系。结果显示,开双风口时,黄板悬挂在棚南侧2.0 m处时诱杀效果最佳;在只开腰风口时,最佳位置为北侧高度为1 m处。回归分析表明,诱虫数量与照度值之间的线性相关不显著。
Yellow board trapping is a common measure to prevent Mushroom fly. In order to explore the effect of suspension position and height of yellow board on the trapping and killing effect of adult Sciarid flies in Pleurotus ostreatus mushroom house, Two types of ventilation modes, one is the double tuyere and the other is the single tuyere. The number of yellow mosquitoes with different hanging heights in the north, middle and south of the canopy and their 1,1.5,2,2.5 m were investigated and analyzed The relationship between the number of attractants and the illuminance at the hanging position. The results showed that when the double tuyere was opened, the yellow board was best when it was hung at 2.0 m on the south side of the shed, and the best position was 1 m on the north side when only the tuyere was opened. Regression analysis showed that the linear correlation between the number of induced insects and illuminance value was not significant.
