对于那些把卵产在植物组织中的昆虫,要直接测定产卵量和确定卵部位是困难的。通常认为孵化的一龄若虫或幼虫反映了卵的数量。但是,由于在不同的寄主品种或植株上卵的孵化率不同,这种间接的产卵量估计就会有错误。为了获得准确的资料。要把雌虫产过卵的部位进行解剖,并在双目解剖镜下计数卵量。不过这种方法也不总是可靠,因为在解剖和检查时会无意识地偶然将卵损坏。乳酸染色技术已被广泛地用来确定稻褐
For those insects that lay their eggs in the plant tissue, it is difficult to determine the number of eggs laid and determine the egg site directly. The first instar nymphs or larvae of hatching are generally considered to reflect the number of eggs. However, indirect hatching estimates can be wrong due to differences in the hatching rates of eggs on different host varieties or plants. In order to obtain accurate information. The females should be dissected ova anatomical sites, and in the binocular dissection microscope counting eggs. However, this method is not always reliable, because the egg will be accidentally damaged during dissection and inspection. Lactic acid staining techniques have been widely used to determine brown rice
