The rice stem borer, Chilo simplex Bulter, is one of the important rice pestsin Kiangsi. The relative proportion of this borer to Schoenobius incertellus Wk. isgradually increased especially after developing the movement of "Control the RiceBorer by Plowing in Autumn, Winter and Early Spring." This situation induced usto take up this problem. This paper deals with the distribution of the borer Chilo simplex with a dis-cussion of the factors influencing its distributional population. in Kiangsi. The lifehistory, behavior of the borer and its relation to Zizania latifolia Hence are also givenin detail. Zizania latifolia is a good shelter for overwintering larvae of the borer,so it is better to discourage the cultivation of this plant in the rice area, or to treatits stubbles soon after harvest or in late March the following year.

(一)二化螟在江西的分布情况,根据三年来的考察,在比例上较三化螟有逐渐扩展的趋势。此项原因,与江西三年来厉行三耕的结果是分不开的。因三耕后,三化螟大部死亡,二化螟则在越冬期中的顽强性大,能逃逸到其他杂草根部去躲藏,所以死亡率不高。 (二)同地区二化螟的分布密度,常因水稻品种的不同、栽培制度的不同、早稻的不同、以及周围有无菱白而发生差异。一般糯稻与粳稻中的二化螟分布密度,较高于籼稻;一季籼和一季糯的二化螟数目,又高于二季籼;早稻枯心苗中极少三化螟,稻枯心苗中渐多,到稻遗株中,则又往往超过了二化螟而占优势。 (三)菱白为二化螟及大螟的越冬大本营,能提早该地区二化螟第一代幼虫的发生期,增加该地区二化螟发生化数,又能使周围水稻田中,二化螟的数量增多,故稻区最好不种菱白。如果一定要种,则必须注意处理它的越冬遗株。处理的方法,根据二化螟及大螟在越冬前后部位的转移情形,抓紧在10月底前或5月底后,将菱白地上部位齐泥割去,深埋土下,或晒乾烧去,即可免其变蛹羽化,继续加害。

In connection with experiments on the control of the rice stem borer, aseries of observations were conducted in 1949 to 1952 in Canton to determinethe form of the distribution of the moth, the egg-mass and the larval popula-tions of this species. It was found that the moth and egg-mass populations inrice seed-beds are in essential agreement with the random distribution of thePoisson series. The larval population in spring-crop fields apparently conformsto the contagious and the negative binomial distributions. The larval population during hibernation period appears to be neither of the random distribution norof the contagious type but agrees with the negative binomial distribution. The population distribution of the injured stems, characterized by the ap-pearance of "dead-hearts" and "white ears" was also studied. The "dead-hearts"popolation in autumn-crop fields conforms with the contagious and the negativebinomial distribution. The distribution of the "white ears" is not at random. It iseither in essential agreement with the contagious or with the negative binomialdistribution, depending on the size of the sampling unit. Based on the form of population distribution the questions of sampling tech-nique, the design of field experiments, the transformation of data for statisticalanalysis, as well as the habits and control of insects have been discussed inrelation to the rice stem borer. Since the populations of larvae and "whiteears" differ significantly from the random distribution, a new technique forsampling has been proposed. It is hoped that this may be useful in the investi-gations on the relative effectiveness of control operations and for census purposes.

(一)本文就昆虫常见的数种集团分布:潘松分布、核心分布和负二项式分布的公式、性质和例子等略加讨论介绍。 (二)我们在广州附近对三化螟各时期和白穗、枯心苗的田间分布型式作了初步的调查,所得结果如下: 1.螟蛾和卵块在秧田上是随机分布的。 2.幼虫在本田分布不随机,符合核心分布和负二项式分布。 3.白穗在田间的分布不随机,1×1丛、2×2丛、……6×6丛各种取样单位型样本均符合负二项式分布,4×4丛、5×5丛和6×6丛三种取样单位型样本则更符合核心分布。 4.稻遗株内越冬幼虫分布不随机,亦不符合核心分布,但符合负二项式分布。 5.造本田枯心苗田间分布不随机,符合核心分布和负二项式分布。 (三)本文就昆虫集团分布型式的调查在实用上的意义,联系到三化螟来讨论,我们论及与虫害调查取样技术、田间试验设计、统计代换方法、昆虫生活习性和害虫防治等各方面的关系;其中取样技术方面,我们举出针对三化螟幼虫在本田和白穗不随机分布的取样新方法的尝试,希望对今后螟害调查工作有所帮助。 (四)最后,我们就一些昆虫分布的特殊问题加以论列,像密度对分布型式的影响,混合集团和环境因素的影响于昆虫集团分布类型等,就中说明了密度过大过...

The rice stem borer, Chilo Simplex Butler causes great damage to therice crop in the medium semi-glutinous rice region, long water rice region,and late semi-glutinous rice region in Kiangsu. Rice stem borer has two generations a year. The first generation is mostabundant between mid-and late July. The second generation is most abundantin mid-late August. In 1952 and 1953, the borer had had reached and suchabundance cave in the middle of September, that a third incomplete generationseemed probable. Experimental result shows that late sowing and late transplanting of riceminimized borer damage.
