Abstract— This study aimed to evaluate the aphidicidal and antifungal activities of Simplicillium lanosoniveum in laboratory conditions. S. lanosoniveum isolate Cs0701 shown to be pathogenic to the aphids, Aphis gossypii, Ceratovacuna lanigera and Hysteroneura setariae. The data showed that isolate Cs0701 exudates had greater mycelial growth-inhibiting effects on plant pathogenic fungi, Sclerotium rolfsii, Alternaria brassicicola and Rhizoctonia solani, in cellophane paper antibiosis test. In addition, mycelial growth of Cochliobolus miyabeanus, Curvularia lunata and Fusarium sp. were partially inhibited by isolate Cs0701 exudates. The culture filtrates of isolate Cs0701 were screened for their antifungal activity against the plant pathogenic fungi. The results revealed that A. brassicicola, Cochliobolus miyabeanus and Curvularia lunata conidial germination was inhibited by isolate Cs0701. The culture filtrate was also able to inhibit conidial germination of jasmine orange (Murraya paniculata) powdery mildew, Oidium murrayae. However, plant host range tests showed that isolate Cs0701 was not pathogenic to Pistia stratiotes, Eichhornia crassipes, Lemma perpusilla and Glycine max. Taken together, these findings provide convincing experimental evidence that S. lanosoniveum isolate Cs0701 is biologically active against both aphids and plant pathogenic fungi including powdery mildew. Pot and field trials are necessary to confirm efficacy of S. lanosoniveum against aphids and plant pathogenic fungi.
Keywords— biological control agent, Simplicillium lanosoniveum, aphidicidal activity, antifungal activity.
