    Pleonomus canaliculatus Falderm. is one of the most destructive soil-inhabitinginsects to wheat in Honan. It causes considerable losses to the crop in spring bycutting the underground part of the stems, causing withering and death of the plant.The life history, distribution, host plants, morphology and rearing methods of theinsect are given in this paper. The overwintering adults become active in spring. Eggs are laid in the topsoil about the plant. They hatch in 5-8 weeks and the larvae grow to maturity inat least 15 months. Pupation takes place during late August up to mid-septemberand the pupal stage requires about 2 weeks. The young adults remain and overwinterin their pupal cells. Fall plowing to a depth of 6 to 9 inches soon after the harvest of summer cropswill destroy a great number of pupae and young adults by breaking up their cells inthe soil. The larvae are thus turned up and exposed to the predators. Rotation ofcrops by using sesame or legumes instead of millet preceding wheat, and summerfallow of the land are found to be helpful to lessening the infestation. Control may be effective by dusting γ-BHC (at,1.5 to 2.5 kgs of 0.5% γ-BHC permow mixed with 3 parts of dry soil or sand) into the top soil by means of a tripodhand-driller between the rows just before the activity of wireworms in spring.

    1.沟金针虫需2年以上完成一代生活史。越冬成虫2月下旬出土,3月中旬至4月中旬为活动盛期,产卵在1至2寸表土内,卵于5月初孵化,卵期为5至8星期。老熟幼虫8月下旬开始化蛹。9月中旬起羽化,蛹期约2星期。成虫羽化后即行越冬。 2.越冬幼虫2月底至3月中旬开始向表土活动(10厘米处地温8—12℃左右),3月中旬及4月全月是为害盛期(80%以上幼虫集中在1至2寸之表土内),8月至12月表土之幼虫密度极小(仅有虫1.2—6.8%),不致为害成灾。 3.沟金针虫之天敌除一种壁虱(Cheyletus sp.)和一种蜘蛛及蚂蚁外,尚有寄生菌2种,具中一种经鉴定为冬虫夏草(Cordyceps sp.)之一种。 4.小麦整地时适当深犁(5—7寸)并精耕细作能毁杀大部分蛹体及成虫,并可将幼虫翻上来供鸟类捕食(9,10月间97%老熟幼虫,在5—7寸土内化蛹及羽化,同时88%幼虫分布于1—7寸土内)。此外以芝麻与豆类为小麦前作及夏季休间结合翻耕曝晒亦能减少虫害损失。 5.沟金针虫在河南的主要为害期系在春季,所以早春於麦行间耩666毒土或毒沙以毒杀向表土上升之幼虫是值得继续研究的。

    Sugar cane borers infest the cane and cause a considerable injury to the plant in China. Four species of sugar-cane borers are commonly found in Kwangtung Province, viz. Diatraea venosata Wk., Chilo infuscatellus Snellen, Eucosma schistaceana Snellen and Sesamia inferens Wk.Trichogramma evanescens Westw. occurs in nature as an egg parasite of the sugar-cane borers.The present experiment on breeding Trichogramma centres around the ways of increasing its viability.The quality and the quantity of the nutrient for the larvae and adults of Trichogramma play an important role in relation to their viability. The contents of the egg of Sitotroga cerealella Oliv. which has been commonly used as a host of the Trichogramma are of poor nutrient quality and quantity for the larvae of this parasite. The eggs of Angoumois grain moth are so small that only one adult Trichogramma emerges from each egg. Such adults are usually smaller in size, less active and with lower reproductive potentiality as compared with those that emerge from the field hosts; besides, the female sex ratio gradually decreases in the successive generations.From the results of an experiment on Trichogramma breeding, it is found that the eggs of Attacus cynthia ricini Boisd. and of Dendrolimus sp. are the most suitable hosts for the propagation of Trichogramma evanescens. The adults of the parasites emerging from such eggs are generally large in size, very active and possess high reproductive potentiality; besides, the female sex ratio remains unchanged in the successive generations. Evidently, the quality and the quantity of the egg contents of these two species of insects fulfil the nutritional requirements for the development of the Trichogramma larvae and they are recommended as hosts for Trichogramma propagationThe average number of adult Trichogramma emerging from a single egg of Dendrolimus sp. and that of Attacus cynthia ricini is 27.3 and 28 respectively with the respective maximum reaching 52 and 59 in the present record. If too many adults emerge from a single egg, both their size and reproductive potentiality would decrease and, moreover, the number of the male individuals would increase and the adult life would shorten. Undoubtedly, all these features are unfavourable for the utilization of the parasites for control of the insect pest as far as the effectiveness of the parasites is concerned. From the standpoint of increasing viability of the parasite, regulation of the number of parasites in the egg during the procedure of propagation of Trichogramma is necessary. Regulation of the number of parasites in the egg means regulation of the quantity of the nutrient for the parasites. The method of checking the occurrence of superparasitism is to regulate the ratio of the number of female Trichogramma and host eggs to 1:1 through the procedure of propagation; the period of oviposition should not exceed one day.The quality of nutrient for adult Trichogramma greatly affects its longivity and reproductive potentiality. The result of a nutritional experiment shows that honey is the most suitable nutrient for it. The adults fed with honey have the longivity increased 8.6 times and the number of the offspring 14.7 times as compared with those fed with distilled water.Cold storage effectively reduces the speed of development of the immature stage of Trichogramma. The mature larvae about to pupate within the host eggs maintain their life for 57 days under 4—7℃ and all of them will come out as adults at room tempeature. The fresh eggs of Dendrolimus sp. and of Attacus cynthia ricini kept in cold storage of 0— 4℃ for 97 days and 61 days respectively are still usable for rearing Trichogramma.In order to increase the adaptability of Trichogramma to the environment of the sugarcane field, the rearing procedure is suggested to proceed in the field or in an indoor environment with fluctuating temperature and humidity. The continuous artificial rearing should not exceed five generations before the liberation of the parasites.The distance of dispersion of Trichogramma eva

    Jin-ding duck is noted for egg-production in Fujien Province. Jin-ding village, the native place of the Jin-ding duck, offers favorable environmental conditions for raising ducks. It has a long history of duck breeding of more than 200 years, and possesses a complete controlling system for rearing(?)ducks on the sea-shore. A high record of egg-production averaging 250 eggs per duck per year has been creared by this village.With the cooperation of the Jin-ding production team, we attempted to increase the Jin-ding duck's egg-production. In October, 1958, 240 fernale ducks of good quality were selected to carry out the first experiment. As a result of improving the method of feeding and controlling, and of artificial acceleration of the metabolic rate, a high record of annual production(346,2 eggs per female)was attained. The success of the experiment was achieved mainly by the elimination of the resting period, i. e. the period without egg production.Upon the basis of the experience gained in the first experiment, second experiment was carried out in April, 1959, with the object of giving better care arid rearing during the duckling stage. The outcome of the experiment was shown in the further increase of egg-productlon, reaching a higher record of annual production(average 360.9 eggs per female).The two experiments mentioned above were not only successful in eliminating the resting period in egg-production but also in altering the habit of moulting, i. e. change of feathers independent of seasons.

    本文报导本教研组与福建省龙海县金定生产大队协作,大搞土洋结合,就提高金定鸭产蛋量的问题进行了试验研究的成果。 1958年10月,我们精选240只优良母鸭组成第一试验鸭(?)进行实验,在金定村原有养鸭经验的基础上,从加强饲养管理的措拖及人工地促进鸭子新陈代谢入手,突破了鸭子的秋冬季休产期,创造了鸭(?)平均每只年产蛋量346.2枚的成绩。 1959年4月,在第一试验鸭(?)已取得的经验基础上建立第二试验鸭(?)。试验系自雏鸭阶段开始,就给予良好的培育和训练。实践的结果产蛋量达到更高的水平,大(?)饲养平均每只母鸭的年产蛋量360.9枚,年平均产蛋率达到98.63%。 (?)阵鸭(?)试验的结果,除了突破休产期,产蛋量显著提高外,同时,换羽特(?)也发生改变,换羽不集中在一个季节,并是边换羽边产蛋。
