为了开展稻飞虱迁飞规律的研究,从1977年起我们进行了试验,并取得了初步结果,现将试验情况简介如下: 一、标记液配方 粘虫、稻纵卷叶螟的标记液由酒精(溶剂),生物染料(碱性品红、碱性品蓝等)和虫胶片(粘着剂)三种成分组成。我们对这三种成分的组合及其比例进行了试验,以寻求适宜的配方。 1.用95％、75％、70％、68％、50％、30％、20％、10％、5％不同浓度的酒精,加0.25％虫胶片和0.25％碱性品红,配制成不同酒精浓度的标记液。
In order to carry out the study on the migration rule of planthoppers, we carried out the experiment since 1977, and achieved preliminary results. The experimental conditions are as follows: First, the marker solution Mythimna asiatica and the rice leaf roller Alcohol (solvent), biological dyes (basic fuchsine, alkaline blue, etc.) and shellac (adhesive) three components. We tested the combination of these three components and their proportions in order to find a suitable formulation. 1. Prepare differently with 95%, 75%, 70%, 68%, 50%, 30%, 20%, 10%, 5% different concentrations of alcohol plus 0.25% shellac and 0.25% Alcohol concentration of the marker fluid.
