In a previous study, protoplast fusion was performed among 3 strains of the entomopathogenic fungi Verticillium lecanii, as a result of which 174 hybrid strains were obtained. The aim of the present study was to screen desirable hybrid strains that have a wide host range or durable effects. Initially, 43 hybrid strains were used in bioassays against the cotton aphid. Of these strains, 30 induced equal or higher mortality as compared to Vertalec (41.9%). Secondly, 50 hybrid strains were used in bioassays against the greenhouse whitefly. Of these strains, 37 exhibited an equal or higher infection rate as compared to that of Mycotal (36.2%). Finally, 50 hybrid strains were applied to cucumber leaves in order to test strain viability under low humidity...

ダイズシストセンチュウに対するVerticillium lecanii プロトプラスト融合株の微生物防除資材としての可能性:プロトプラスト融合は植物寄生性線虫の生物的防除において有用な手法と成り得るか? OAK

Verticillium lecanii is a potentially useful biological control agent (BCA) for soybean cyst nematode (SCN), Heterodera glycines. The objective of this study was to screen hybrid strains of V. lecanii, derived from protoplast fusion, for effective control agents of SCN, and to investigate whether the protoplast fusion technique is an effective tool for development of nematode control agents. Three parental strains (Vertalec®, Mycotal®, and B-2) and their 162 hybrid strains were screened in greenhouse pot tests. Some of these hybrid strains suppressed damage on soybean plants and reduced the density of SCN in the soil. In particular, one hybrid strain, AaF42, was observed to reduce the nematode egg density by 93.2% as compared with the control. Furthermore,...
