一种监测粉虱成虫发生数量的新型取样器

A new sampling device for monitoring the population dynamics of whitefly adults

介绍了一种适合监测粉虱成虫发生数量的新型取样器。它由白铁皮、半透明塑料盆、透明塑料瓶等材料制作而成。将白铁皮围成圆筒罩住单株寄主植物,半透明塑料盆扣在铁筒上并在中央做一圆孔,将置入黄色粘纸的塑料瓶口接入圆孔,即可对粉虱成虫的发生数量进行调查。该装置使用方便且耐用。

A new sampling device,consisting of a galvanized iron sheet cylinder,a semitransparent plastic basin and a transparent plastic vial, was designed for more effectively monitoring the population dynamics of whitefly adults. When it is used, the cylinder is placed to envelop an individual host plant,and covered with the basin upside down;a hole is opened in the basin＇s center and the plastic vial lined with thin sticky yellow paper is attached to the hole with its opening downwards. The device is easy and simple to operate and durable.
