螨类和农业、畜牧业及人类保健有非常密切的关系。近年来,我们经常收到各地寄来的各种螨类标本,要求鉴定,由于标本的采集、保存及制作方法不够妥善,标本数量既不充分,制成的标本也不符合分类鉴定的要求。现将我们使用的一些方法介绍如下,供参考试用。 一、采集方法 螨类分布广泛,在土壤中、动植物体上、池沼和江河湖海里都有。要采集所需要的标本,首先了解螨类的栖息场所和生活习性。据此设计出一些较好的方法,既省工时,又可得到较多的标本。检取螨类,大型而体壁较硬者,可用小镊子夹取;多数螨类体小而柔软,不能用镊子夹取,以免弄坏,常用描图小毛笔或有柄的针,先端用水或保存液湿润后粘取。也可用采集小昆虫的吸虫管来吸取(图1)。
Mites and agriculture, animal husbandry and human health have a very close relationship. In recent years, we often receive all kinds of mites samples sent from all over the world to request identification. Because specimens are not properly collected, preserved and produced, the number of specimens is not sufficient and the specimens produced do not meet the requirements of classification and appraisal. Now we use some of the methods described below, for reference trial. First, the acquisition method Mites distributed widely in the soil, plants and animals, ponds and rivers and lakes are. To collect the required specimens, first understand the mites habitat and habits. Based on this, we designed some better methods to save time and more specimens. Check mites, large and hard walls, can be small tweezers to take; most of the small and soft body mites, can not use tweezers to grip, so as not to damage, commonly used to describe small brush or handle needle, apex with water or Preservative liquid wet sticky. It can also be used to collect small insect parasitic tube to absorb (Figure 1).
