Antagonism of Paecilomyces spp. isolated from banana (Musa spp.) roots and rhizosphere against Radopholus similis
Banana (Musaspp.) in East Africa is threatened by pests and diseases, of which the burrowingnematode, Radopholus similis, is among the most serious and difficult to control. Fungal antagonists, such as Paecilomyces spp., can aid in controlling R. similis. In this study, Paecilomyces spp. was isolate...

| description | Banana (Musaspp.) in East Africa is threatened by pests and diseases, of which the burrowingnematode, Radopholus similis, is among the most serious and difficult to control. Fungal antagonists, such as Paecilomyces spp., can aid in controlling R. similis. In this study, Paecilomyces spp. was isolatedfrom banana roots and rhizosphere in fields in Uganda with high and low densities of R. similis. Fungi were more abundant in the rhizosphere than on roots in the field with low R. similis density, whereas the reverse occurred in the field with high R. similisdensity. A total of 23 isolates of Paecilomyces spp. were collected, of which Paecilomyces lilacinuswas the most abundant species. This is the first reportshowing the high presence of Paecilomycesspp. in the rhizosphere of bananas. Bioassays revealed thatfiltrates of P. lilacinusand Paecilomyces marquandii caused reversible paralysis of male and juvenileR. similis. Paecilomyces lilacinus isolate 23N5-2 caused greatest paralysis, which was not influenced by filtrate concentration. |

El cultivo de banano (Musaspp.) en Africa Oriental se ve afectado por plagas y enfermedades, en-tre las cuales el nematodo barrenador, Radopholus similis,es uno de los más serios y difíciles de con-trolar. Los hongos antagonistas, como Paecilomycesspp., pueden ayudar a controlar R. similis. En esteestudio, se aisló Paecilomycesspp. de raíces y rizosfera de banano con densidades altas y bajas de R.similisen Uganda. Se encontraron los hongos en mayor abundancia en la rizosfera que en las raícesen los campos con bajas densidades de R. similis, mientras que lo contrario ocurrió en los campos conaltas densidades de R. similis. Se colectó un total de 23 aislamientos de Paecilomycesspp., siendo Paeci-lomyces lilacinusla especie más abundante. Este es el primer registro que indica la alta presencia dePaecilomycesspp. en la rizosfera de bananos. Los bioensayos demostraron que los filtrados de P. lilaci-nusy Paecilomyces marquandiicausan parálisis reversible de machos y juveniles de R. similis. La cepa23N5-2 de P. lilacinuscausó la mayor parálisis, independientemente de la concentración del filtrado. 2007 2018-03-07T11:25:56Z 2018-03-07T11:25:56Z Journal Article https://hdl.handle.net/10568/91448 en fr Limited Access Kilama, P., Dubois, T., Coyne, D., Niere, B., Gold, C.S. & Adipala, E.
