In 1963, five neighbouring brigades with different cropping systems in Yuankiang and Nanhsien, Hunan were chosen for the comparative studies on the relations between the cropping system and the population of the paddy borer, Tryporyza incertulas (Wlk.), in order to look for the most economical and effective tactics and methods of control for this serious pest.

In 1963, five neighbouring brigades with different cropping systems in Yuankiang and Nanhsien, Hunan were chosen for the comparative studies on the relations between the cropping system and the population of the paddy borer, Tryporyza incertulas (Wlk.), in order to look for the most economical and effective tactics and methods of control for this serious pest. The chief results were summarized as follows: 1. Among neighbouring brigades in the same region, a sharp difference in the amount of initial population of the paddy borer is one of the important factors influencing its population and damage in the current year. To destroy almost thoroughly the hibernating larvae of the paddy borer by means of cultural practices on a sufficient scale, not only the damage by the first and second generations could be prevented, but the population and damage of the later generations might also be reduced. On this basis, if it is possible to suppress further the population of the second generation by ploughing and flooding the early rice fields on proper time, the damage made by the later generations might be even more effectively repressed. 2. The degree of borer damage depends upon the combined effect of the degree of coincidence of the vunlerable growth stages of rice and the prevailing period of larval hatching and also the borer population. So far as cultural centrol is concerned, to regulate the growth stages of rice and the repression of borer population should be both utilized as much as possible. 3. The cultivation of double-cropping rice (with two crops on the same fields per year) brings not only advantageous but also disadvantageous effects to the development of the paddy borer. Under the conditions of Yuankiang and Nanhsien, Hunan, certain practices in the cultivation of double-cropping rice might be utilized as a part of the means of paddy borer control. 4. In rice belts with complicated cropping system, early planting of the medium-rice could not only avoid serious borer damage, but might also induce the second generation moths laying more eggs on small areas of late medium-rice or single cropping late rice, thus making it possible to kill more borers with less insecticides and save the burden of chemical control for the following generation. 5. It was suggested that the paddy borer control should be carried on the basis of cultural methods, that is, to supress the borer population and regulate the growth stages of rice by means of cultural practices as much as possible, and then recruited with necessary applications of insecticides.

1963年在湖南沅江及南县选择隣近的种植制不同的五个生产大队,調查对比、分析耕作栽培措施及其他生态因素,与三化螟种羣数量消长及为害程度的关系,探索最經济有效的稻螟防治策略和综合措施。各对比点結果一致証明,在同一地区相距不远的大队間,三化螟发生基数大小的悬殊差別,是决定当年发生数量及为害程度輕重的一个重要因素。在适当的面积(大队)上結合耕作栽培措施相当彻底地消灭三化螟越冬幼虫,不仅可控制第一、二代的为害,且对压低第三、四代的发生量和为害程度也有明显的作用。在此基础上如能进一步结合夏收灭茬連續压低虫源,更可加強对后期螟害的控制。螟害程度决定于水稻最易受害生育期与稻螟盛发期配合的程度和螟虫发生数量的綜合影响。因此,在农业防治方面,結合耕作栽培措施压低虫源及調节水稻生育期并恶化螟虫的生活条件,均应尽可能的利用。扩种双季稻对三化螟的发生为害有有利和不利的两面。在湘北滨湖稻区的情况下,可以結合双季稻的耕作栽培,連續压低虫源作为控制螟害的一項措施。在种植制复杂的稻区,中稻早栽既可避免第三代三化螟的为害,且可促使第二、三代三化螟更多地集中在小面积的迟中稻或单季晚稻上,有利于集中施药歼灭。稻螟的防治策略应以农业防治为基础,結合...

The present article deals with an appraisal of three old cultural methods forthe control of millet borer(Chilo infuscatellus Snellen).These are:(1)gatheringand burning off the millet stubbles that harbour the overwintering larvae:(2)delayed planting of millet so that it would avoid the peak of oviposition:(3)laying out the so-called“trapping field”,which is said to be more attractiveto the gravid female moths and then killing the young borers in that fieldwith an effective insecticide.It appears that none of them is feasible inmountainous regions.The peasant of Yenan,however,has a common practice in millet planting,i.e.,far-distance crop rotation.It was found that a distance as far as.1000M is adequate for lessening the borer infestation.This is especially truefor the mountain terrace where infestation is usually high in millet plotswithout crop rotation.In localities where the practice of crop rotation isimpracticable,thinning out the infested seedlings which are then used aslivestock feed is recommended.

本文分二部分。第一部分概述了延安地区栽培方式与粟灰螟发生的关系,指出由虫源的有无多寡,粟灰螟以为害山地粟为主,为害川地粟的主要是玉米螟。第二部分对老的和仍在提倡的三种防治粟灰螟的栽培方法,即:越冬期防治,调节播种期和早播诱杀田进行了探讨,指出了它们在生产上未能大规模推行的原因;并提出了合理倒茬与间苗灭虫两项可供选择的办法和提出这种办法的依据。
