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、早晚稻的不同、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;一季晚籼和一季晚糯的二化螟数目,又高于二季晚籼;早稻枯心苗中极少三化螟,晚稻枯心苗中渐多,到晚稻遗株中,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。

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.

Experimental result shows that late sowing and late transplanting of riceminimized borer damage.

(一)二化螟在江苏省中粳区、沤田区及晚粳区为害严重,大部分枯心苗均为其造成。白穗中幼虫数目相当高,最多一株有137头。 (二)二化螟的发蛾期,一般来讲,第一代盛发期约在6月中、下旬。第二代盛发期约在8月中、下旬。根据观察记载资料,望亭一带,1952年、1953年均在9月中、下旬又起高峰,可能有不完全第三代的出现。 (三)试验记录中指出,人为的移栽对蚁螟的生存,有抑制作用。在栽培制度上,应控制第一代蛾螟卵盛孵期,在秧田内进行。以期达到水稻少受二化螟的为害。 (四)水稻受二化螟为害后,除造成枯心苗白穗外,并造成有虫株。其百分率最高占14.5%。有虫株穗与健穗,穗重相差0.46克。千粒重最高相差3.09克。 (五)在稻根稻草中,二化螟越冬比例,稻根为43.41%,稻草为56.59%。 (六)在不同播种期;移栽期各处理间,受二化螟为害,差异显著。望亭一带适宜播种期、移植期,以5月25日播种,6月28日移栽为最佳。 (七)第一代螟卵之寄生率平均为25.46%。寄生蜂种类有:(1)日本赤眼蜂,(2)稻螟黑卵蜂。 (八)在防治上,除运用行之有效的治螟办法,如秧田捕蛾采卵、点灯诱蛾、剪除枯心苗和白穗、保护寄生蜂、处理稻根外,...

The present paper deals with the extent of abundance of insect pests in their course of appearance in relation to the control measures applied. The ecological significance of abundance and the destructiveness of Tryporyza incertulas (Wlk.), Chilo suppressalis Wlk. and Pachydiplosis orzyzea Wood-Mason, are analysed to account for the extent of abundance in which these pests should be controlled. As the percentage of development is changed into probit, the probit being about 4—6 will match the 15.87—84.13...

The present paper deals with the extent of abundance of insect pests in their course of appearance in relation to the control measures applied. The ecological significance of abundance and the destructiveness of Tryporyza incertulas (Wlk.), Chilo suppressalis Wlk. and Pachydiplosis orzyzea Wood-Mason, are analysed to account for the extent of abundance in which these pests should be controlled. As the percentage of development is changed into probit, the probit being about 4—6 will match the 15.87—84.13 percent of development. In this respect, the population in the whole generation will reach 68.268% and it will come to a point where the insect pest should be controlled. Formulas for controlling the larvae, eggs and moths are proposed.

为探求害虫防治时期,和发生数量方面的防治标准,以三化螟(Tryporyza incertulas (Wlk.)、二化螟(Chilo suppressalis Wlk.)和稻瘿蚊(Pachydiplosis oryzae Wood-mason)三种水稻钻心害虫为材料,探討钻心类害虫防治标准的規律,提出如下意見: 1.关于防治时期的标准,認为可将施药时虫态的发育进度百分率数字,换算为概率单位,在概率单位为4—6时,相当于15.87—84.13%时的害虫相对发生数量,占全世代总发生数量的68.268%,可見在該段短时間(一般約十数天)的虫数,代表了虫羣的大半数,可看作标准的盛发期,在此时間数列范围內,似可作为防治时期的标准。 2.关于发生数量的防治标准,以三化螟及稻瘿蚊为例进行討論:認为应以幼虫侵入作物后至老熟(或蛹化)期間,每虫所能造成的被害株数为基础,求出幼虫密度的防治标准,然后根据調查时的不同虫态,再伸算各該虫态的防治标准。本文列举了各虫态密度防治标准的計算公式,并以广州及南京两地的三化螟和广东信宜的稻瘿蚊为例,作出在各种具体条件下,虫口密度防治标准检索表。
