The present study is devoted to the identification and isolation of translocations in the mosquito Culex pipiens pollens Coq. Virgin female mosquitoes carrying genetic markers, recessive red eye (r) and black head (bh) were mated with wild males pretreated with X-ray radiation and the F1 obtained were individually backcrossed with red-eyed and black-headed ones. Among the group of individuals tested with reciprocal cross translocation strains were isolated and maintained. Two of them are M-linked and the...

The present study is devoted to the identification and isolation of translocations in the mosquito Culex pipiens pollens Coq. Virgin female mosquitoes carrying genetic markers, recessive red eye (r) and black head (bh) were mated with wild males pretreated with X-ray radiation and the F1 obtained were individually backcrossed with red-eyed and black-headed ones. Among the group of individuals tested with reciprocal cross translocation strains were isolated and maintained. Two of them are M-linked and the two others m-link-ed. The translocation heterozygote strains showed different degrees of sterility, ranging from 53.1 to 71.5 per cent. The observations indicated that the sterility was due to lethality of the fertilized eggs.

相互易位能使生殖细胞分裂失常而导致部份不育,故可用来作为防治害虫的手段。我们用1000到8000伦琴的X射线,照射的羽化24到48小时的淡色库蚊(Culex pipiens pallens Coq.)的野生型雄蚊,诱发了性染色体和常染色体之间的相互易位。为鉴定并分离出这种相互易位,用未经交配的具有红眼(r)和黑头(bh)两种突变性状为标记的雌蚊与受照射的野生型雄蚊进行单对交配。F_1表现为野生型,BC_1由r与bh两种性状所表现的拟连锁r-bh及分离比例上的反常,分别从4000、5000、6000和8000伦琴的四个照射组中,各分离出一种相互易位杂合子。其中由5000和8000伦琴诱发所得为雄性连锁相互易位杂合子T~M,而由4000和6000伦琴诱发所得为雌性连锁相互易位杂合子T~m。都已育成稳定的半不育品系。四个品系的不育性为53.10%—71.50%。经详细观察,发现不育性的主要原因是受精卵的致死所造成。

This paper is a report of the study of recent years on the preparation and isolation of NPB (Nuclear Polyhedral Bodies) from the noctuid moth Prodenia litura Fab. infested by polyhedrosis . With a view to increasing the productiom of NPB, such factors as the larval stage of the insect host, kind of feeding stuff, environmental temperature were studied. It was found that at the 3rd instar stage, if the insect host was treated with anaesthetic ether the incubation period was shortened and the yield of NPB was higher than the untreated ones.It was also shown that young larvae of 1-3 instars of this insect host could be effectively controlled by spraying with the suspension of the virus. In addition, tests of the virulence of raw-virus suspension obtained from the reared larvae indicated that these suspensions were more effective than the purified ones.

本文通过近几年来对感染剂量,宿主龄期、饲料、温度等因素的室内试验研究,以及利用乙醚麻醉喂毒宿主进行病毒制剂生产的探讨,结果表明,要达到有效的生物防治害虫的效果,必须掌握在幼虫低龄期(即3龄期前)进行喷毒,利用乙醚麻醉宿主可以大大缩短潜伏期,提高病毒制剂的产量。

The cultivation and isolation of S.natans have been known of diffi- culty for that it does not grow on the ordinary bacterial medium,and it usually occurs as a sheathed filament,mucous substances enclosed on which are easy to be contaminated by associated bacteria. In the present work,by using potassium nitrateglucose as an enriched medium,isolation is made first by spreading on agar plates containing glucose and peptone of lower concentration(Medium S),and then by subcul- ting on agar plate containing...

The cultivation and isolation of S.natans have been known of diffi- culty for that it does not grow on the ordinary bacterial medium,and it usually occurs as a sheathed filament,mucous substances enclosed on which are easy to be contaminated by associated bacteria. In the present work,by using potassium nitrateglucose as an enriched medium,isolation is made first by spreading on agar plates containing glucose and peptone of lower concentration(Medium S),and then by subcul- ting on agar plate containing casitone and glycerine (Medium G) until a pure cuiture is obtained. The tricome-forming bacteria so isolated are characterized as follows: Sheath prominent;cells are rods,1.20x1.90μ;appeared in chains within a sheath of uniform width;Gram negative;attiring motile (subpolar flagella) when in a liquid medium.Colonies on plate containing MnCO_3 are whitish and unable to oxidize manganous compounds.Liquefaction of gelatin slight;sometimes with false branching;never fermentative. By using casamino acid as a rich organic nitrogen sourse,better growth and a Smooth type of colonies are obtained (S-type),cells of which are usually large and almost sheathless.On poor growing medium (Medium S), a filamentous and rough type of colonies appeared (R type),the cells of which are smaller and sheathed.Colonies shown a transition between smooth-rough type are also appeared on medium of different composition and concentration. By the characterisitics discribed,this trichomeforming bacterias is identified as Sphaerotilus natans.The principal cheracters of its two strains isolated (FD-7611 and E-773) are similar.

多年来对于废水处理的研究(包括城市生活污水和工业废水),在物理学、化学、生物学等方面都进行许多工作。在实践中逐渐认识到,通过生物学的方法,也就是通过微生物生物化学的方法处理废水,是解决水污染的重要途径之一,因而得到极其广泛的应用。废水所进行的微生物生化处理研究工作中,为了进一步搞清微生物作用的机理,有必要对废水处理中的微生物群体(包括活性污泥和生物膜)进行较深入的研究。而丝状微生物是群体中重要的一类,其中尤以具衣鞘的球衣细菌的作用更为突出。因此,对球衣细菌的控制利用,成为废水生物学处理中一个引人注目的课题,为此我们对球衣细菌进行了研究。本文包括球衣细菌纯种分离技术的研究,球衣细茵分离菌株的鉴定及其存活时间的研究。
