摘要：

1.白僵菌(Beauveria bassiana(Bals.)Vuill.)是大豆食心虫幼虫的寄生性真菌。自然寄生率5—10％,有时可达30％以上,是造成大豆食心虫幼虫自然死亡的有力因素之一。 2.白僵菌的发育及孢子发芽温度是18—28℃,其中以25—28℃最为适宜。适宜的发芽湿度要在99％以上。在土壤中如果温度适宜(25—28℃)土壤含水量10％以上就可以引起幼虫显著寄生。 3.幼虫体沾着一定数量的病菌孢子可以引起大量死亡,如果幼虫体上沾着孢子数4944个以上则可致100％寄生,不足此数的,寄生率成比例地降低。菌粉在太阳光照射下6天后寄生力受到影啊,30天以后寄生作用已极小。病菌对于带菌的幼虫虽可同样寄生,但寄生能力要比直接使幼虫接触孢子要小得多。在室温下的菌粉中,病菌的生活力(致病力)可以保持一年左右。 4.利用白僵菌防治大豆食心虫的效果是:室内不论菌粉浓度及用量多少,寄生率均达100％。小区试验可致幼虫寄生70.19—100％,田间防治可以提高幼虫寄生30.15—36.11％,降低成虫羽化49.83—69.8％。 5.作者认为:利用白僵菌防治大豆食心虫是有希望的。今后是对于大量繁殖病菌的方法,施用药剂时期及与农药混用以提高效果有进一步研究之必要。

摘要：

White muscadin (Beauveria bassiana (Bals.) Vuill. is a fungus infecting the larvaeof soy-bean pod borer. In nature it caused infection of larvae to 5--10%, sometimeshigher than 30%. This paper deals with a preliminary study on the factors that effect theinfectivity of the fungus and tests with it to control the pest in 1954--1957. Theresults obtained are sumarized as follows. The optimal temperature for the germination of spores of this fungus was found to be21--28℃. Relative humidity above 95 % was found to be necessary for spore germination.10--20 water contant in soil by weight was found to give the highest percentage of infection.It also observed that: the large number of spore (above 2944) settling on the larvae willresult in 100 % infection. Two methods were used in making the preperation of the fungous prepratus; Mixingspore-dust with pulverized peat, and mixing fungous culture on potato-mash together withpeat and then pulverized them, the latter is more convenint. As results of testing, this fungus in laboratory, it was shown that no matter what thedifference of dosage or of concentrition, 100 % larvae were infected by this fungus. In small plots test, 70.19--100 % of the larvae were infected before the emergence ofadults. In field expriments, the percentage of parasitized larvae was 30.15--36.11 % andthe emergence of adults was reduced by 49.83--69.8 %.
