家蠶에서 分離된 새로운 微胞子蟲 K79의 病理學籍 硏究 : Ⅱ .微胞子蟲의 病原成 및 發育經過 Ⅱ.Pathogenicity and Developmental Progress of the Microsporidia

尹在洙,林種聲 한국잠사학회 1985 한국잠사곤충학회지 Vol.27 No.1

In order to clarify the taxanomic position of a new microsporidia K79 which was isolated from the silkworm larvae, Bombyx mori L. in Korea in 1979, the following several experiments such as estimation of pathogenicity in diferent instar, histopathological examination under light and electronic microscope and examination of fine structures of the spores were carried out and their results obtained are as follows. In the test of pathogenicity by oral inoculation, the new microsporidia K79 was lower than Nosema bombycis and the susceptibility of the new microsporidia to silkworm was getting lower as the silkworm larvae grew. The lesion of Silkworms' tissue which was infected with the new microsporidia K79 was found in the epithelial cells of trachea, fat body and silk gland cells. The developmental process of the new microsporidia K79 in vivo could be divided into the following five stages: sporoplasm, schizont, sporont, sporoblast, and spore. This process was just the same as that of N. bombycis, but its development was slower than that of N. bombycis. Several differences in the fine structure of the spore under electron microscope, which could be important keys for the classification of microsporidia, were obtained. Anchoring disk and polaroplast lamella of the new microsporidian spore were disclosed to be different from those of N. bombycis. An average number of polar filament coils of the new microsporidian spore was 16 at an angle of 75°. On the basis of various keys for the classification of microsporidia, the results obtained from various experiments proved that the newly isolated microsporidia should be classified into the Genus, "Nosema", but its further classification for species should be conducted in the future. Therefore, it may be reasonable that the new microsporidia is temperally classified as Nosema sp. K79 considering the fact that it was discovered in Korea in 1979.

눈꽃동충하초균의 누에 감염이 고치에 미치는 영향

윤재수 한국곤충학회 2001 Entomological Research Vol.31 No.2

눈꽃동충하초균의 감염이 고치에 미치는 영향을 알아보기 위하여 5령 누에에 균을 접종하고 실험을 수행하였다. 저 농도 눈꽃동충하초균의 침입을 받은 누에는 건강한 누에처럼 생존하여도 경과일수의 지연, 체중의 감소를 가져 왔고, 견질면으로 보아도 고치 무게, 고치층 무게, 번데기 무게 등의 감소로 견질이 저하되었다. Cordyceps, Paecilomycesjaponica, was inoculated against silkworm, Bombyx mori in the 5th instals to know effect of cordyceps on the cocoon quality. Feeding period of larvae in 5th instals was more longer than normal larvae. Larval body weight, cocoon weight, cocoon layer weight, and pupal weight were reduced 21.56%, 13.64%, 15.18% and 11.74% respectively. The cocoon quality of silkworms which inoculated with cordyceps was inferior than cocoon quality of normal silkworms.

Effect of Cordyceps, Paecillomyces sp., Cordyceps pruinosa and Paecillomyces japonica, on the Development of Domestic Silkworm, Bombyx mori

윤재수 한국곤충학회 2005 Entomological Research Vol.35 No.4

This study was carried out to investigate pathogenicity of cordyceps on the silkworm larva, Bombyx mori. For experiment, Cordyceps, Pacillomyces sp. strain collected from Chilgab mountain area in Chungnam Province, Cordyceps pruinosa collected from Chiak mountain area in Gangwon Province and Pacillomyces japonica collected from dead silkworm larva at the rearing room in Sangju National University were used. Spores of cordyceps were propagated on sterile PDA (potato dextrose agar 39 g, water 1,000 mL) at 25.C for 21 days. Spores of cordyceps isolated from media were inoculated on integuments of 3rd instar newly exuviated silkworm for pathogenicity on the silkworm larvae. The cordyceps used in this study was highly infectious to the silkworms. Virulence of cordyceps was different depending on species. Pacillomyces japonica was the most efficacious with 70% mortality on silkworm larvae. Cordyceps had adverse effect on the overall rearing from larval period to mounting of matured silkworm larvae, cocoon making, pupation and moth emergence. The result suggests that cordyceps used in this study may be useful for the tracking of biocontrol.

Studies on Entomopathogenic Fungi Isolated from Dead Pine Caterpillars, Dendrolimus spectabilis

윤재수 한국곤충학회 2003 Entomological Research Vol.33 No.4

Entomopathogenic fungi isolated from pine caterpillars, as biological control agents were evaluated against the 5th instar larvae of silkworms, bombyx mori. The body weights of silkworm larvae were reduced by entomopathogenic fungi. Virulence of the spores isolated from the insects was more stronger than that of the spores isolated from media. LD50 value of the pathogen was 6,464×103 spores/ml. Entomopathogenic fungi, Beauveria, isolated from dead pine caterpillars was possible agents for use in microbiological control.
