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...

紫蓝小灰蝶在广西柳州沙塘是因种野百合属绿肥豆荚的主要害虫。此外该虫还为害木豆、刀豆和扁豆。根据文献该虫也为害荷兰豆和蚕豆。 小灰蝶和豆荚螟为害绿肥豆荚的特征和区别文中有详细的叙述。 小灰蝶以卵态在绿肥的花苞、嫩荚、茎和叶上越冬。幼虫为害豆类的时期自3月下旬直至12月上旬。在饲育室内一年发生7—8代。一世代需时20—176日。 成熟绿肥豆荚被害率自1.8—22.6%不等,本虫更为害花朵和嫩荚,使之凋落,不能结实。 绿肥作物终年开花结荚,不独是小灰蝶越冬的理想寄主,也助长其他重要豆作害虫如豆荚螟的繁殖。作者建议及时和合法刈割绿肥是解决本虫和若干其他豆作害虫的有效方法。

The present paper gives a report on the observations of the citrus psylla, Diaphorina citri Kuwayama, found in Focchow and Changchow of Fukien Province. The insect has been reported as an important citrus pest in south-eastern Asia, and is heretofore recorded from Kwangtung by Hoffmann (1936) and from Taiwan by Shiraki (1934). The citrus psylla attacks l3 species of plants of the family Rutaceae. Eggs are laid on the leaves of the young growth. The feeding of both the nymphs and adults on foliage of the new terminal growth results in the leaves, becoming thick and leathery. The leaves and the young shoots are usually distorted, dwarfed, or in severe cases, even dried. The annual life cycle of the insect in Fukien Province has not been investigated thoroughly. However, preliminary observations made during the year of 1952 show that different developmental tsages of citrus psylla could be found all the year round. There is no marked phenomenon of hibernation. Concentration of a number of adults on the same leaf usually occurs during the winter months. Both nymphs and adults become very abundant in April when dam- ages are most severe. Sixteen days are required for the insect to complete a generation in August. The number of individuals de- creases after September. The nymphs are attacked heavily by three species of chalcid parasites of the family Encyrtidae. Morphological descriptions of the different stages of the insect are also given in this paper.

柑桔木虫分布于亚洲东南的热带和亚热带地区,为害芸香科植物,是柑桔类主要害虫之一。国内除台湾、广东外,其他各地尚无报告。现知福建的福州、漳州也都有,本文系在福州观察的记述。成虫栖息取食常在芽和叶里的叶脉上。产卵于嫩芽,若虫孵化后就在新梢为害。被害叶芽枯干,枝梢萎缩,新叶畸形卷曲。生活史尚待详细研究,但根据一年来的初步观察,一年到头都可以找到各个虫期;自四月以后为害渐见严重,至九、十月则逐渐减少。夏季完成一个世代约需十六天。冬季多以成虫密集叶里,但无休眠迹象。育得跳小蜂科寄生蜂三种,九月至十一月若虫被寄生者甚多。本文对于柑桔木虫各期形态有简略的叙述。
