ROJAS M, ELEONORA; PEREA A, ERIKA I y PINEDA V, YOLANDA A. Fusarium spp. on Trialeurodes vaporariorum from tobáceo and kidney beans of García Rovira, Santander, Colombia. Rev. Colomb. Entomol. [online]. 2003, vol.29, n.2, pp.165-168. ISSN 0120-0488.
During the last decade, García Rovira province (Santander department, Colombia) has had some problems with greenhouse whitefly control, "Trialeurodes vaporariorum (Westwood)", which affeets several crops of this province. Some Fusarium species can be considered promissory entomopathogenic for biological control of sucking inseets (aphids, scales and white flies). The goal of this study was to know the Fusarium species predominant in the zone, from leaves and/or folióles of tobáceo and kidney beans with T. vaporariorum. 168 colonies of Fusarium were isolated and identified, according to their macroscopic characteristics (morphology, coloration and diameter) developed on Potato Dextrose Agar (PDA) and their microscopic characteristics (macroconidia, microconidia, conidiophores and chlamydoconidia) on Carnation Leaf Agar (CLA). Species identification of all isolated colonies was carried out by contrasting obtained characteristics on PDA and CLA with different identification keys available up to date. Thirteen Fusarium species were isolated and identified from 7. vaporariorum. They were: F sambucinum, F graminearum, F compactum, Fequiseti, F avenaceum, F longipes, F reticulatum, F oxysporum, F heterosporum, Fculmorum, F lateritium, F coccophilum, and F crookwellense. Further research must prove whether these species can be involved with T. vaporariorum population control.
