The pine caterpiller,Dendrolimus punctatus Walker, has the habit of leav-ing the crown part of a tree and hibernating under the loose bark of thetrunk. The present paper reports the successful control of this pest by treatinga part of the trunk with a DDT suspension. All experiments were carried outat Nanking, 1947-48. When solutions and water suspension containing 5% DDT, 1%γ 666,or 5% 1068 were applied with a brush to the trunk for a width of one footand over-wintering larvae were allowed to crawl over the treated area, all theinsecticides tested were found to be effective when freshly applied. After oneweek, how-ever, only preparations containing DDT remained effective. DDTwater suspension was markedly better than DDT in kerosene, soybean oil, oracetone. Trees treated with a 5% DDT water suspension were still very toxic tothe caterpillars at the end of six weeks. The number of caterpillars crawling over a DDT-treated area would notinfluence the toxicity of the DDT film under practical field conditions. In oneexperiment all area of twenty inches square, treated with a 5% DDT suspension,still showed high toxicity to the caterpillars after 1,800 larvae had crawled overthe area in a period of nine days. Caterpillars were found to be more resistant to DDT in summer than inwinter. By increasing either the concentration of DDT to 10-15% or thewidth of the treated area to 2-3 feet, the "trunk treatment method" could beused as well in summer, if the caterpillars were beaten down to the grounedafter the trees had been treated with DDT. Under the field conditions in Nanking, 1947-48, the pine caterpilIars beganto leave the crown part of the trees and seek hibenation quarters in November.They became active again early in March, hence tree should he treated withDDT not later than the dates mentioned above. A total of 157,658 trees were treated with DDT on the Purple Mountain,Nanking, 1948. Examinations showed that larval population decreased 90-99%in the treated area, while in the check area an increase in population of16-350% had been observed.

本文研究在松树干上涂刷有持久性的药剂以防治越冬松毛虫的可能性。1947—48年在南京试验及实施防治的结果简述如下: (一)在实验室内使越冬松毛虫爬行越过涂有一市尺宽各种药液的松树干的结果,证明5% DDT,1%γ666,与5% 1068的悬液或溶液。在涂药的当天均 有相当高的杀虫效力,惟一周以后γ666与1068完全失效,仅DDT仍保持强大的毒力。DDT水悬液显著较DDT火油、大豆油或丙酮溶液为佳。涂有5%DDT悬液的松树杆曝露田间六星期后,杀死松毛虫能力仍达100%。 (二)据试验的结果,自制的可湿性DDT,内含DDT50%,稀释剂45%,与肥皂5%,尚适宜于防治松毛虫之用。 (三)松毛虫爬行的次数对涂药面积上DDT毒力的影响极微,在二十平方市寸涂有5% DDT悬液的小面积上,9天之内经过1800头松毛虫爬行后,毒力仍未减小,死亡率尚在90%以上。 (四)夏季松毛虫较越冬松毛虫不易杀死。夏季松毛虫抵抗DDT的能力随龄期而增强。试验中显示如增加药液浓度至含DDT 10—15%,或增加涂药的宽度至2—3市尺,夏季幼虫亦能中毒死亡。故树干涂药法亦可应用在夏季防治上,惟必须在涂药后将松毛虫从树上击落,使其在爬返树冠...

The present paper gives a report on a study of the life his- tory of a destructive pest, Melanauster chinensis Forster, of citrus trees in Foochow during the years 1951 and 1952. It has been found that the adults lay eggs beginning from the last part of May until the end of July. Eggs are inserted in the bark of the tree trunk about 1. 4 inches from the ground. Incubation period lasts from 9 to 14 days. After hatching the young larvae feed under the bark for three or four months. In October they bore into the wood from a place about one to two inches above the ground. Overwintering of the larvae in the burrows generally begins in November or December. They resume actti- vity in March the following year. Pupation takes place abou the middle part of April. The pupal period lasts from 18 to 20 days. After emergence the adults remain in the pupal cells in the upper part of their burrows for about five to eight days. The adults appear from the middle part of May to the middle part of August. Burrows made by the larvae under the bark as well as in the wood have been studied carefully. Recommendations have been given to improve the original technique of destroying the larvae by probing with wire.

星天牛为柑桔主要害虫之一,研究此种害虫者颇不乏人,但就所见文献中关于该虫习性的报道,多不足作为防治的有力参考。笔者有鉴及此,于一九五一至一九五二年在福州研究这一害虫的生活习性,尤其对于幼虫为害的隧道,有比较详细的观察。把果农钩杀幼虫这一防治方法的实践与理论相结合,初步掌握了幼虫在柑桔树干中钻蛀为害的规律,使过去所谓奥妙不可捉摸的钩杀技术得到了解析,同时也把这一技术从现有的水平提高了一步,希望可以为一般从事柑桔栽培工作者所掌握,成为简单易学的一件事。五月下旬至七月下旬均有成虫产卵,产卵位置平均离地面1.4寸,卵期九至十四天。幼虫孵化后即从产卵处蛀入,向下蛀食于表皮与木质部之间,其向下蛀食范围多在地面下五寸以内。一般在三、四个月后亦即在十月左右,以成熟或将成熟的幼虫,蛀入木质部内,作一隧道,准备过冬及化蛹。蛀入孔多在地面下—、二寸处。一般幼虫在十—、二月开始休眠越冬,历时约三、四个月,翌年三月以后又开始恢复活动。四月中旬开始化蛹,蛹期十八至二十天。成虫羽化后在蛹室内停留五至八天。自五月中旬至七月中旬都有成虫出现,迄八月中旬仍见有极少数成虫。幼虫所营隧道的形状、长短,都有一定的规律,文中有详细的叙述,并附有图解。

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。
