为验证昆虫采样系统用于棉盲蝽田间虫量调查的效果,于2010年在江苏省大丰市蚕豆田和茼蒿田绿盲蝽1代和2代4龄、5龄若虫发生盛期进行了试验。结果表明,吸虫器抽吸虫量高于或等同于常规拍打法,且可获得各虫龄或虫态,但对5龄以下若虫虫体有损伤。因此,建议吸虫器实际应用中,应尽量选择在3龄若虫高峰后进行;取样单位蚕豆田每点抽吸1m2、茼蒿田每点抽吸0·25m2,尽量抽吸植株的中上部(嫩头或花);缩短抽吸时间,以减少长时间操作、机器振动对虫体的损伤。同时对设备提出了改进建议。
In order to verify the effectiveness of the insect sampling system for the investigation of insect population in the field of cotton bug, in 2010, the first and second generation 4th and 5th instar nymphs of Vicia faba and Soybean fields in Dafeng City, Jiangsu Province, test. The results showed that the number of parasitic nematodes was higher than or equal to the conventional beating method, and each age or insect state can be obtained, but the number of 5th instar nymphs were damaged. Therefore, it is suggested that in the practical application of the trematode, the selection should be conducted after the 3rd instar nymphs are peaked. The sampling unit should draw 1m2 per point in the broad bean field and 0 · 25m2 per point in the trefoil. Aspirate the middle and upper part of the plant Or flowers); shorten the suction time to reduce long-term operation, the machine vibration damage to parasites. At the same time proposed improvements to the equipment.
