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 injurious insects of cotton of this province, however, have not hithertobeen carefully studied, especially the pink bollworm, which annually reducesthe cotton production by 10 to 30 per cent. The present authors spent twoyears in observing the life history and habits of this insect, in attempting tofind some effective control measures. The result is herewith summarized :- 1. In the vicinity of Wu-chang, the pink bollworm has three generationsa year. The first generation occupies May and July. The second one occursin mid-July and the last in late-August. Due to the lower temperature, theemergence of the first generation need about two months. 2. In day time, the adult is usually inactive, while in windless night,after seven o'clock, it becomes very active and lays eggs mostly on green bollsand calyx. about a week later, the eggs hatch and the newly-hatched larvaeare shortly getting into the bolls. After four days they often eat into theseeds. Ten days later, the lint is so stunted as to become dusky yellow incolor, thus both the yield and the quality of cotton are greatly lowered. Themature larvae appear about half a month after. 3. Field experiments have shown that three dustings of 10% DDT- sulfurpowder were very effective. In the severely damaged cotton area, the thirdspray may be simultaneously done with controlling the cotton leaf-hoppers andthe cotton leaf-rollers. 4. About 84% hibernating larvae in cotton seeds will come out when thecotton exposed in sun light and stored in the farmer's house. Hence it seemsadvisable to put cloth or other soft material covers on the cotton stored inorder to collect and kill the larvae under them. In addition, destruction of allremaining bolls on the cotton stalks, as early as possible in winter is important. 5. For controlling the bollworms in cotton store-houses, the followingresults have been obtained 50% wettable DDT diluted with 20 parts of water,91% of larvae were killed within 30 days; 6.5% 666 (benzene hexachloride)gave a mortality of 63% in four months. Wettable 6.5% 666 diluted withwater (1:100), has been proved to be the most effective ovicide which destroys99.4% of eggs while parathion (E605) also gave a very high mortality at97.7%. But 50% wettable DDT (1:100) Kills eggs at 64.2% and lead arsena-te only 16.2% respectively. 6. There were 39.1% overwintering larvae parasitized by parasitic mitesand wasps. Among them, most are the mite, Pediculoides ventricosus Newport,while the parasitic wasps Eurypterna arakawae Mats. less than 0.5%.

红铃虫在南方棉区为害棉花相当严重,除去脱落蕾铃外,僵黄花率为10—30%,我们针对这个严重问题,进行了红铃虫生活史的观察研究与防治方法试验,写出初步结果,提供防治参考。 1.红铃虫在华中武昌棉区一年有三代。第一代羽化在5至6月,7月中旬为第二代;8月下旬为第三代;第一代的蛹和幼虫所需时期均较第二、三代长。 2.成虫白天不活动,夜晚7时以后无风天气活跃最盛,产卵以在青铃上及花萼上为最多。孵化后三十多分钟即钻入棉桃内为害,4天即侵入棉籽内取食,10天棉瓤纤维呈僵黄状,半月后幼虫即可老熟(第三代的)。 3.田间防治红铃虫以10%滴滴涕硫磺粉喷三次效果显著,在后期棉虫严重地区可结合防治叶跳虫卷叶虫等同时进行。 4.籽花内的幼虫在群众家里及晒花时逃出84%,因此指导群众将籽花堆上加覆盖物,再结合帘架晒花是消减过冬红铃虫最经济有效的办法。 4.防治仓库越冬红铃虫以50%可混性滴滴涕1:30倍水溶液杀虫效果最佳。30天内死亡率达91%.6.5%可混性666(1:20)死亡率为63%。但是1:100倍的水溶液杀卵效率高到99.4%。稀释万分之一的E605为97.7%。50%可混性滴滴涕1:100杀卵率为64.2%,砒酸铃最差...
