Nosema liturae sp. n. was isolated from larvae of Spodoptera litura in Guangzhou. It easily transmitted to Heliothis armigera. In the two lepidopterous, the microsporidian caused n general infection and was highly pathogenic. Also, experimental infection was found in eight, addition lepidopterous host; but Bombyx mori, Lymantria dispar, Clostera anachoreta and Plutella maculipennis were refractory to the infection. The fresh spores were typically long ovoid in shape, with a mean size of 4.34±0.27×1.99±0.14μm....

Nosema liturae sp. n. was isolated from larvae of Spodoptera litura in Guangzhou. It easily transmitted to Heliothis armigera. In the two lepidopterous, the microsporidian caused n general infection and was highly pathogenic. Also, experimental infection was found in eight, addition lepidopterous host; but Bombyx mori, Lymantria dispar, Clostera anachoreta and Plutella maculipennis were refractory to the infection. The fresh spores were typically long ovoid in shape, with a mean size of 4.34±0.27×1.99±0.14μm. The mean polar filament length was 94.2±11.97μm. Ultrastruetural studies showed that the filament was normally arranged in 12—13 coils at an angle of 78—82° to the axie of spores. The species was found to be distinct from all previously described Nosema reported from Lepidoptera.

从广州的斜纹夜蛾幼虫体内分离到一种新的Nosema属微孢子虫。这种微孢子虫很容易接种到棉铃虫体内,对上述两种鳞翅目昆虫具有很高的致病力,引起整体侵染。交叉侵染试验发现这种微孢子虫还侵染另外8种鳞翅目试验寄主,但不侵染桑蚕、舞毒蛾、杨扇舟蛾和小菜蛾。典型的新鲜孢子长卵圆形,4.34±0.27×1.99±0.14μm。极丝平均长度为94.2±11.97μm。超微结构研究发现,极丝通常单层绕成12-13圈,与孢子长轴的夹角78-82°。研究发现这个种不同于以前报道的所有侵染鳞翅目昆虫的Nosema属微孢子虫,故定为新种M.liturae.

Nosema sp. was firstly dissociated from the larva of cerace stipatana Walker on the big foliar camphortree (Cinnamomum camphora) in Sichuan in 1984.Investigated by electron microscopic scanning, ultrathin section and emulsion agglutinative reaction with antibody serum Ig-G of N.bombycis L., it was confirmed that Nosema sp was a species Which was different from Nosema bombycis.Through biological test,it was found that Nosema sp.had infection to silkworm.It parasitized in the silk gland,the...

Nosema sp. was firstly dissociated from the larva of cerace stipatana Walker on the big foliar camphortree (Cinnamomum camphora) in Sichuan in 1984.Investigated by electron microscopic scanning, ultrathin section and emulsion agglutinative reaction with antibody serum Ig-G of N.bombycis L., it was confirmed that Nosema sp was a species Which was different from Nosema bombycis.Through biological test,it was found that Nosema sp.had infection to silkworm.It parasitized in the silk gland,the muscles (including muscular layer of the midgut), the malpighian tubule and the membrane of the trachea tissue of silkworm.The parasitization was not found in the epithelial tissues of midgut (including the cylindrical cell and cup-shaped cell).After inoculating silkworm with Nosema sp.,no infection was found in embryos. This is an obvious difference between Nosema sp and N.bombycis.

本文首次报道了龙眼裳卷蛾微孢子虫对家蚕的致病感染试验结果。1985年在三台等县第一次发现野外昆虫感染微孢子虫病,以其新鲜孢子虫添食家蚕可感染发病,影响生长发育甚至死亡;镜检病蚕蚕体及组织切片,可看到病原体和明显病变。还与家蚕微粒子原虫进行了比较观察。
