The present paper attempts to find the rules of forecasting the possible degree ofdamage by the rice stem borer. According to the data from investigations in Kwangsiduring the years 1958--1964, it is generalized that the fluctuations of the damages causedby the borer can be divided, in conformity with its serial generations, into three differenttypes: the decreasing type, the increasing type, and the type with an increase in the thirdgeneration.

The present paper attempts to find the rules of forecasting the possible degree ofdamage by the rice stem borer. According to the data from investigations in Kwangsiduring the years 1958--1964, it is generalized that the fluctuations of the damages causedby the borer can be divided, in conformity with its serial generations, into three differenttypes: the decreasing type, the increasing type, and the type with an increase in the thirdgeneration. The main cause resulting in the three different types is due to the different plantingdates. When the date is relatively early in the year, the decreasing type occurs; whenit is relatively late, the increasing type happens; when it is between these two dates, thetype with highest increase in the third generation takes place. A typical diagram has been made to illustrate the correlation between the differentplanting dates and the different types of borer damages. As soon as the date of plan-ting early rice is known, we can make use of the diagram to forecast the situation ofthe borer damage during the whole year. Having obtained the yearly average of the relative values of increase or decreasebetween the generations in each of the three developmental types, and the date of plan-ting of early rice in a given year, it is possible to calculate the degree of damage inthe succeeding generations. For short-term forecast of borer damage, larval density should be made the principalreference point. Computing from larval density and the degree of damage occurred, bymeans of the quadric curvilinear equation, estimates of damage will be obtained. The following equations have been used in the present research: Generation 1: 100y = 10.54e~(0.0019x) Generation 3: 100y = 16. 83e~(0.002x) Generation 2: 100y = 52.6 logx -- 100.5 Generation 4: 10y = 17.52 logx -- 41.98y indicates the percentage of the infestation of rice stem borer, x indicates the density oflarvae No./mow.

1.从广西贵县1958—1964年的七年螟害调查资料,可以将全年螟害的消长趋势,划分为世代递减发生型、世代递增发生型和第三世代多发型等三种螟害发生型。 2.形成三种螟害发生型的原因,主要系由于水稻播植期的早晚与螟虫发生为害的不同组合所致。水稻播植期较早的年份,形成世代递减发生型;播植期较晚的年份,形成世代递增发生型:播植期居中的年份,则形成第三世代多发型。 3.本文根据历史资料,订出早、中、晚播植期的标准,以此标准为坐标图上的横轴,各世代螟害率为纵轴,作出了播种期与螟害型的关系模式图。根据这个模式图,在某年掌握了早稻播种期以后,就可以作出该年螟害发生发展趋势的展望。 4.求算三种螟害发生型各世代之间的螟害增减比值历年平均数,在某年获悉早稻播种期和第一世代实测螟害率以后,就可以根据这个比值平均数,依次推算以后各世代的预测螟害率。 5.关于各世代螟害率的近期预测,本文主张以幼虫虫口密度为依据,求算虫口密度与其所造成螟害率的二次函数曲线方程式,在获得幼虫密度以后,代入方程式来计算近期预测的螟害率。 广西贵县各世代的预测螟害率(y)与幼虫虫口密度(x,单位:头/亩)关系的方程式如下: 第一代 ...
