  • Abstract : Loos found no significant morphological differences between populations of Radopholus similis from the banana varieties, Lacatan, Robusta and Gros Michel. To study the life-cycle, he infected the young roots of banana seedlings soon after germination on glass slides on which fine sand was heaped around the root. Females laid an average of 3.5 to 4.6 eggs per day and continued to lay for two weeks. The eggs hatched in five to seven days in water and in seven to eight days in roots. Larvae persisted for 10 to 13 days after hatching but most had matured to adults in 11 days. Adults began to lay two days after the last moult. Fertilization was necessary for egg production, and the number of eggs laid seemed to depend on nutritional factors. All larval stages and females were infective, but males were unable to infect roots. The life-cycle took 20 to 25 days to complete.
