Entomomycete of rice planthopper was isolated from Brown planthopper (Nilaparvata lugens) at Lian-ban, Fuzhou in Nov. 1978. Inoculating test indicates that this fungus can parasitize Brown planthopper, Rice fulgolia (Sogata furcifera) and Small brown planthopper (Delphacodes striatalla). The percentage of parasitism varies from 60-80%.The mycelium when young develops profusely, bearing branches of septate threads, measuring 10-14 μ in width. But after repeated sporogenesis they quickly disorganize and disappear....

Entomomycete of rice planthopper was isolated from Brown planthopper (Nilaparvata lugens) at Lian-ban, Fuzhou in Nov. 1978. Inoculating test indicates that this fungus can parasitize Brown planthopper, Rice fulgolia (Sogata furcifera) and Small brown planthopper (Delphacodes striatalla). The percentage of parasitism varies from 60-80%.The mycelium when young develops profusely, bearing branches of septate threads, measuring 10-14 μ in width. But after repeated sporogenesis they quickly disorganize and disappear. The unbranched sporangiophore is clavillose or cylindraceous, 70-220×14-18 μ diam. That large subglobose solitary sporangium with papilla has a diameter of 28.5-49.8 μ is cut off apically from the sporangiophore. The sporangium when ripen discharges violently. Most sporangia germinate directly to form hyphal bodies but a few of them form secondary sporangium. Resting syore is subglobose with hirtose appendages. The sexual phase is not discovered.The favourable temperature for growth rang rom 15-35℃ with an optimum at 25-30℃, but below 12℃ or above 40℃ the growth is inhibited. This fungus may grow at pH 3.5-11.5 but growing is best at pH 5. Most sporangia lose their activity under sunlight or ultraviolet light (30w) for 1-2 hours. The germination of sporangium and its invasion requires high humidity.The longevity of resting spore is about a year or more under room temperature on PDA. The fungus is suitable to grow and sporulate in the following media: PDA, potato, sweet potato and so on.The infection tube from germinating sporangium penetrates into the body of the planthopper at the segmacoria. The infected planthopper will kill within 1-2 days or sometimes 4-5 days. Then the sporangiophore will grow out from the segmacoria of the insects body.

我们从褐稻虱上分离到一种虫霉,经多次测试表明,此菌对褐稻虱、白背稻虱和灰稻虱均有寄生致病能力.其寄生致死率一般可达60-80%.但对稻叶蝉无效.飞虱虫霉的生长和产孢温度范围是15-35℃,以25-30℃最适.pH3.5-11.5均能生长,但以pH5最佳.孢子囊对光较敏感,在直射日光或紫外光(30w)下经1-2小时,大多数丧失生活力,但不受散射光的影响.孢子囊的形成、弹射、萌发及侵入均需高湿.对培养基要求不严格,马铃薯葡萄糖洋菜培养基、马铃薯片、甘薯片等均能良好生长繁殖.休眠孢子在室温下可存活一年以上.稻飞虱感染虫霉后,快则1-2天,慢则4-5天即罹病致死.

锥栗溃疡病是近年来在福建省锥栗栽培区建瓯、南平等地发现的一种危险性病害。经鉴定,病原菌为寄生内座壳菌。病原菌的菌丝在PDA培养基上生长良好,培养7~10天后形成大量分生孢子,但培养30天后仍不形成子囊。菌丝生长景适温度为24~26℃,最适pH值为5~6。在96.1%高湿条件下,分生孢子萌发率最高,低于50%相对湿度,则完全不萌发。研究结果表明,锥栗溃疡病的症状、病原菌形态特征及其生物学特性与检疫病害板栗疫病一致,所以该病害必须严格控制,避免扩散流行成灾。

Morphogenetic process of oogamous reproduction are described in Eucampia zood-iacus Ehr.. Within the spermatogonangium, the contractive protoplasm is enclosed by a thin elongate-elliptical membrane . Small naked sp-irmatogonia are produced in the membrane which will disappear during the meiotic prophase of spermatocytes , In the spermatogonangia each give 64 or 128 uniflagel-late sperms. Each of oogonium contains only an egg. After fertilization, the zygotc swells considerably , and develops an auxosporc in big spheroid. The initial cell is not developed inside the auxospore membrane and is formed by deformation of whole auxospore without any abandoned residual membranes.The cell size of sexual phase gives between 10 and 31 urn in widths,in most cases in both size ranges of 10-17 um 23-31 μm, so that the auxospores and initial cells of two size ranges are frequently observed in a same cultured material.The different effects of temperature, light intensity and salinity on sexualization are observed in E. zoodiacus. Low temperature(12℃) and light intensityd 000 1x)were found to be optimal for male formation, and the sexualization will be reduced correspondingly with increasing temperature and light intensity. More male cells have been produced under the condition with photoperiod of 12 hours daily. A strong sexual reaction appear in 22. 5‰ salinity.

在浮动弯角藻卵配生殖中发现两种特殊的形态发生;糖原孢囊里形成一个长椭圆形薄膜和原初细胞由复大孢子变形产生。在有性细胞大小范内常发生分段生殖和由此产生两次细胞复大现象。在低温(12℃)低光(1000 1x)和22.5‰盐度条件下,该藻呈最适的性化效应。
