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 present paper reports on two lamellicorn beetles: Adoretus tennuimacu-latus Waterh. and Liocola brevitarsis Lew. The former belongs to the subfamilyRutelinae and the later Cetoniinae. Adoretus tennuimaculatus has two generations per year at Lientang. Thefirst active period of adults mostly occured in June and the second period inAugust. After 7: 30 at night, the adults went out and stayed on various hostplant leaves feeding or copulating and then back into earth at dawn. Larvaewere not strict in selecting the soil but most of them lived in the garden soil,mound soil and. clay landside. Liocola brevitarsis has only one generation per year at Lientang. The adultperiod was from June to September and some of them lengthened out mid-Octo-ber. Adults flied out at day time and sucked the different part of hosts: as theflesh of fruit, the juice of tree and the corn ear, once in a few days. Larvaeselected the soils more strictly. They concentrated in compost and rich humussoil. Controlling methods: (1) To spray 0.5%γ666 or 25% DDT emulsion (250water:1 emulsion) once to the host leaves was effective in protecting against theadults of Adoretus till its last period of activity. (2) To shake the tree to makethe adults of Adoretus fall down and then unroll a piece of white cloth underthe tree to gather the adults. (3) To make a bamboo cylinder, 12-16 in. long,which was filled with rotten fruits and nectar, and trap all the adults of Liocolain this cylinder. (4) To clean out the compost before June in order to kill mostof the larvae and pupae of Liocola.

The severity of red-leaf disease of millet, as measured by the height as well as the yielding capacity, is directly correlated to the stage of development of the plants at which infestation takes place. As a rule, plants infested at seedling stage are much more damaged than those infested at the later stages of development. Date of sowing effects the percentages of diseased plants. In general, earlier sowing produces more diseased plants than later sowings. Nevertheless, it is largely determined by the prevalence...

The severity of red-leaf disease of millet, as measured by the height as well as the yielding capacity, is directly correlated to the stage of development of the plants at which infestation takes place. As a rule, plants infested at seedling stage are much more damaged than those infested at the later stages of development. Date of sowing effects the percentages of diseased plants. In general, earlier sowing produces more diseased plants than later sowings. Nevertheless, it is largely determined by the prevalence of the migrating aphids. Introducing corn aphids, in the previous autumn, on host plants of red-leaf virus, including 11 species of perannual gramineous weeds, under screen cages in open field, did not reveal the presence of either survival insects or egg mass during the next spring. It indicates that the corn aphids don't overwinter on these weeds under the present experimental conditions. Two species of perannual weeds, viz. (Panicum virgatum L. & Boutelona curitipendula (Michx.) Torr.),are found to carry the virus over the winter under natural conditions. Attempts for controlling the disease with organic phosphorus insectides have been so far? unsuccessful. Among 200 or more varieties and strains of millets, 4 of them have been proved to be highly tolerant to the disease and possessing desirable agronomic characters.

在田間隔离昆虫传染的条件,于小米不同生长期所进行的人工分期接种試驗,証明接种期愈早对植株的生长和产量的影响愈大,并发現根系受紅叶病毒的影响最为显著。在田间条件下不同播种期对小米感染红叶病的百分率的影响不大一致,但根据两年的結果,早播一般均较正常播种期的发病率为高。人工飼育蚜虫的試驗,未发現玉米蚜能在鵝冠草等11种多年生禾本科杂草上越冬。在所測定的11种植物中,小米紅叶病病毒能在黍草(Panicum virgatum L.)和垂穗草(Bouteloua curitipendula(Michx.)Torr.)上越冬。三年的試驗証明,田间不同时期噴射內吸杀虫药剂虽可減少蚜虫数量,但对小米产量和紅叶病发病率均无显著影响。对二百多个小米品系連續四年进行紅叶病抗病性的鑑定,发現大多数品种都是高度感病的,沒有抗病和免疫的品种,但有許多高度耐病的品系。选出耐病而且农艺性状良好的P14A、NP—157、P354和摩里等四个品系。
