feltiae Filipjev, 1934 (Rhabditida: Steinemematidae) was studied at the Laboratory of Biological Control which belongs to Agronomy Faculty of the National University of Colombia. Larvae of last urge of the greater moth of Galleria mellonella, were exposed to 8000 infective/box. Dissections were done daily and developmental stages, life cycle and ratio sexes were determinated for native nematode. The life cycle consisted of six stages: egg term, four juvenile periods and one adult stage. The last one period began at infective juvenile 3 (13). This one could be in two ways: If there is enough food and the initial density is low, the mal e and female are developed. Eggs from female of first generation will develop males and females for second generation. The 13 generation will be produced from female of second cycle. The last one correspond to the long time cycle (1O days / 20°C). If nutrients are low, 13 cycle develop female and males of the first generation. Eggs for this cycle will be develop infective juvenile stage. This one will be the short life (6 days / 20°C). Nematodes are tolerant to temperatures between 10 to 24°C. Temperature about 15°C will show 62% of female, while 30°C will correspond to the 43% offemale.
