Studies on the chemical control of European corn borer, Pyrausta nubilalis Hubner, were carried out in Liaoning province in 1958—1962. Application of 5% DDT granules or 1% γ BHC granules was found to be very effective in combating the borers infesting maize. When applied at the proper time, the above-mentioned insecticides killed 100% of the first generation larvae and reduced the total borer population by 70% and 60% respectively. Grapules could best be applied on the late whorl stage, or on the date...

Studies on the chemical control of European corn borer, Pyrausta nubilalis Hubner, were carried out in Liaoning province in 1958—1962. Application of 5% DDT granules or 1% γ BHC granules was found to be very effective in combating the borers infesting maize. When applied at the proper time, the above-mentioned insecticides killed 100% of the first generation larvae and reduced the total borer population by 70% and 60% respectively. Grapules could best be applied on the late whorl stage, or on the date 20—25 days after the first appearance of egg mass in the field, or near the end of the oviposition period of the first generation. A single application of granules at late whorl stage was sufficient and an additional application before this period proved to be unnecessary. Insecticides prepared by thoroughly mixing the toxicant with the carrier before making granules were found to be superior to those prepared by merely mixing the toxicant with the granules. Control borers infesting millet with a mixture of 5% DDT dust and 0.5% γ BHC dust on a ratio of 1: 1 was highly effective. The best time to apply insecticide was during the oviposition peak, which generally appeared about 15—20 days after the appearance of the first egg mass in the field. A mortality of 70—80% was expected when the dust was applied to the lower portion of the plants.

1958—1962年在辽宁省新金、辽中及沈阳三地,对为害玉米及谷子的玉米螟进行了化学防治試驗。試驗証明:玉米心叶末期或田間初見卵后20—25天,或田間第一代螟卵接近绝跡时均可作为辽宁地区进行化学防治适期的标准。用5%DDT或1%六六六顆粒剂适期施药,对第一代玉米螟都有100%效果。于玉米收获前剖查,經5%DDT与1%六六六顆粒剂处理后,減虫率分別为70%以上和60%以上。心叶期增加施药次数并不能增加防治效果。从顆粒剂的加工方法来看,混和顆粒剂优于拌粉顆粒剂。谷子上化学防治的适宜时期,为田间初見卵后15—20天,相当于第一代卵高峯或卵高峯后3—5天。用5%DDT、0.5%六六六1∶1混合粉剂,每亩4斤施于谷子茎基部,一次施药,可得70—80%以上的防治效果。

Three sap-transmissible virus isolates form Corn and Sorghum in the vic-inity of Beijing were identified as maize dwarf mosaic virus strain-B (MDMV-B).The MDMV-B can be transmitred by green peach aphids (Myzus persicae)from Corn to Corn. Three isolaeet do not infect Johnson grass (Sorghum hale-perse (L.)pers).The inactivation properties of the virus are:(1)dilution andpoint 10~(-2)-10~(-3),(2)thermal inactivation point 50-55℃,(3)ageing in vi-fro 1-2 days. Some Flexuous particles approximately 735±15nm and pinwheelinclusions were observed in the cytoplasm of infected sorghum leafcell. Setariaviridis (L) Beauv, Digitaria Sanguinalis (L) Scop, Eleusine indic (L) Gaerth,and Arthraxan Sanguinalis (L) Scop, Eleusine indica (L) Gaertn, and ArthraxanLancelatus (Roxb) Hochst were found to be the natural hosts of MDMV in thevicinity of BEijing. The virus also infected Spodiopogon sibiricus Trin, a perannual gramineousplant.

北京郊区玉米和高粱上的三个汁传病毒分离物鉴定为玉米矮花叶病毒株系B (MDMV),它可被桃蚜(Myzus persicoe)由玉米传至玉米,这三个分离物不侵染约翰逊草(Sorghum halepense (L)pers)。稀释终点是10~(-2)-10~(-3);致死温度是50-55℃;体外保毒期是1-2天。MDMV的颗拉长度是735±15毫微米,在染病高粱叶的细胞质中观察到凤轮状内含体。狗尾草(Setariaviridis(L)Beauv),马唐(Digitavia Sanguinalis (L)Scop),蟋蟀草(Eleusine indica (L)Gaertn),矛叶荩草(Arthraxan Lancelatus (Roxb)Hochst)是北京地区MDMV的天然寄主。该病毒也侵染大油芒(SpodiopogonSibiricus Trin)。

Five rice virus diseascs have been found to occur in Chekiang namely,the rice dwarf, rice yellow stunt,rice yellow dwarf, transmitted by Nepho-tettix cincticeps,and the rice stripe, rice black-streaked dwarf transmittedby Loadelphax stritellus. Measures for effective control of these diseases arereported here. Plants of rice, whcat,barley and maize suffured seriouslyfrom the rice black-streaked dwarf disease virus during 1965-1967. The riceblack-streaked dwarf virus, as revealed from our observation,was easilytransmitted by the planthopper but not easily tansmisible from maize plantsto the other of the above mentioned hosts. Although the planthopper couldsurvive on maize plants only a short length of time,the maize cropwas usually seriously infected and was damaged more than the other hosts.The vector could acquire the RBSDV from the infected Poa annua plantwhich showed no symptoms in field. The rice dwarf,sometimes coexistedwith rice transitory yellow,was prcvailing during 1969-1973. This paper dealswith some relations between RDV and its vector,especially the relationbetween the two major migratory periods of the vector,e. g. to early ricecrop from its dormant place and later,to late rice crop from early ricecrop,and the RDV infection.

本文总结了1965-1977年水稻病毒病主要是黑条矮缩病、普通矮缩病的发生规律和传毒昆虫传病特点等方面的调查研究工作。水稻黑条矮缩病由灰稻虱传播。灰稻虱能把病毒自水稻传到水稻、大小麦、玉米,但难以把病毒从玉米传到其它寄主上。已证实田间早熟禾可以作为黑条矮缩病无症带毒寄主。水稻普通矮缩病于1969-1973年发生,为害严重,讨论了黑尾叶蝉发生,特别是二个迁移时期(越冬代向早稻,第2、3代向晚稻)和普矫发病防治的关系。
