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...

The sorghum aphid; Aphis sacchari Zehntner is insect pest of epidemic properties ofsorghum in the Northeast, Inner Mongoria, Shangtung, and Hopei. Its overwintering hostis Miscanthus sacchariflourus and its alternative summer host is Andropon sorghum. Over-wintering eggs are sometimes laid on sorghum too, but the stem mothers always die outdue to shortage of food. The winged aphids migrate from Miscanthus to sorghum inearly spring. At the beginning of multiplication, the aphid colony is concentrated on thelower part,Ist to 3rd leaves of sorghum.There are four peaks of the appearance ofwinged aphids in a year. The first peak occurs in the seedling stage of sorghum, thesecond in 6--10 leave stage, the third in 12--16 leave stage, and the fourth in the seedmaturing stage. Cach year there is a total of 16 generations. In the second generation thewinged aphids migrate from the overwintering host to sorghum. The sexuales appear inthe 16th generation and the females lay eggs to pass winter. Many species of naturalenemies were found belonghg to the Coccinellidae, Syrphidae, Chrysopidae, Braconidaeand Ochthiphilidae. The size of aphid population is usually correlated with the culturaland climatic conditions. Destruction of the overwintering. host plant is considered veryimportant to reduce the aphid population in sorghum field. 6%r wettable 666 (1: 150) and parathion emulsion (1: 15000) are the effective insec-ticides used at present hme. Systox emulsion were tested at the growing stage of sorghum.also giving very good result, but the residual effects to higher animals need further investi-gations.

高粱蚜是我国北方高梁产区的大害虫,东北三省、内蒙古、山东、河北等地为其猖撅发生区。经在东北调查及接种试验证明,荻草是它的越冬寄主。夏寄主在东北等地只有高粱,并不寄生玉米等禾本科作物。绝大部分越冬卵产在荻草的地上部叶鞘内及叶背面。高粱蚜在夏寄主高粱上亦能产卵。但在孵化后往往因无食物而死亡。越冬卵量和早春蚜量团荻草生长的场所不同而有差别,一般在土质松软、窝风、向阳条件下者较多;土质板结和夏、秋积水条件下的草甸、坟地处较少。早春迁至高粱后多寄生在基部叶片上,在7月上旬前1—3叶蚜量约为全株蚜量的98%。有翅蚜在全年迁飞中有4次高峰:第1次在高粱出苗后,第2次在6—10片叶时,第3次在12—16片叶时,第四次在高粱成熟前后。无翅蚜也有一定迁移能力,同样是扩散蔓延的重要因素,田间测定24小时迁移距离为1—3.3米。在室外饲育观察全年共繁殖16代,第2代出现有翅蚜,第16代出现性蚜,平均每个胎生雌蚜产仔47头,一般70—80头,最多者达180多头;平均温度15℃时,发育期间为13天,21℃时8—9天,23℃时6—7天。卵于4月下旬杏花开放前后孵化。5月下旬榆钱成熟时开始向高粱植株上迁飞,7月中旬至8月中旬是为害高峰期,8...

The peach leaf hopper, Erythroneura sp., is one of the important insect pests of thepeach tree in Kiangsu Province. There were four overlapping generations a year. Theoverwintering adults became active in the middle of March, and migrated immediately tothe peach trees as soon as the young leaves sprouted out. They could not develop on theleaves of broad bean, cabbage and radish. The appearance of adult stage of each generation was as follows:The overwintering adults hid among several evergreen trees such as Juniperuschinensis var. Kaizuca Hort., J. chinensis L., Biota orientalis (Linn.)., Cryptomeria japo-nica D. Don., Pinus massoniana Lamb., Myrica rubra Sieb. et Zucc. It was found thatabout 30% of these adults survived even at a low temperature of --20℃ in late Feb-ruary. Chemical control experiments were carried out both in the laboratory and in theorchards. The results indicated that the malathion miscible oil (25%) at the dilution of1:1,000--2,000 was the most effective spraying formulation, which gave 100% mortalities4 hours after treatment, while 30% parathion and 50% ethion (1240) at the dilution of1:1,000 and 1:500 respectively also gave satisfactory control and exhibited comparativelylonger residual effects. The DDT miscible oil (25%) at the dilution of 1:250 was alsoeffective for controlling this species, which gave 100% mortalities 24 hours after spray-ing in the orchard, and showed the longest residual effect.

桃一点叶蝉在长江流域为桃的重要害虫,据在南京、徐州、洞庭东山等地调查,为害桃的叶蝉共有4种即:桃一点叶蝉Erythroneura sp.,小绿叶蝉Empoasca flavescens,大绿叶蝉Cicadella viridis及棉叶蝉Chlorita biguttula。以桃一点叶蝉为主。它的主要寄主是桃,其他尚有杏、李、中国樱桃、贴梗海棠、月季、苹果、梨等。桃一点叶蝉在南京一年发生四代,以第四代成虫在常绿树如龙柏、侧柏、柳杉、桧柏、马尾松、杨梅上越冬。至早春桃现蕾萌芽时,从越冬寄主上大部分直接迁飞到桃上,少量可到其他寄主上,4月以后都集中到桃上,直到晚秋开始作越冬之迁飞。至11月中下旬全部迁到常绿树上越冬。 室内药效测定结果:25%马拉松乳剂,30%E-605及25%DDT乳剂效果最好,41%敌百虫效果不好,效果最差的是10%γ666乳剂。两次田间防治试验结果与室内一致。在桃园内为避免经常使用DDT而引起螨类的大发生,可采用马拉松,E-605来代替或与DDT混合使用防治桃一点叶蝉及其他桃树害虫。
