La posibilidad de ser utilizado en un programa de manejo integrado de broca plantea la necesidad de desarrollar estudios básicos en el campo. El estudio se realizó en un lote de café variedad Colombia en Supía, Caldas, a 1320 msnm, con 22°C y 75 por ciento de humedad relativa. Se seleccionaron 50 árboles y de cada uno, una rama con 30 frutos. Se utilizaron mangas entomológicas para infestar las ramas con 250 brocas adultas y 12 horas después se realizó la liberación de 250 adultos del parasitoide, por manga. Se evaluó diariamente una manga entomológica durante 48 días, disecando 25 brocas parasitadas y registrando el estado del parasitoide encontrado. El ciclo de vida se determinó de acuerdo a la aparición de cada estado biológico. Se observó que los adultos de P. coffea vivieron en promedio 2,5 días. El huevo tuvo una duración de 5 días, las larvas L1 5 días, las L2 6 días, L3 12 días y las pupas 15 días. El ciclo de vida desde huevo hasta la aparición de los primeros adultos fue de 43 días y de adulto a emergencia 3 días. Se encontró que P. coffea en la relación 1:1, broca:avispa utilizada en el estudio, produjo superparasitismo, observándose hasta 17 larvas en el interior del cuerpo de una broca.Summary: Phymastichus coffea La Salle, togolese wasp, is an endoparasitoid of Hypothenemus hampei (Ferrari) female adults, introduced to Colombia in 1996. This wasp attacks the female beetle as it begins to bore into the coffee berry whilst it is still attached to the plant. The possibility for this wasp to be incorporated as control measure on the basis of an integrated pest management program against H. hampei, posed the necessity to carry out basic research under field conditions. This study was located in a Colombia variety coffee plot in Supía, Caldas, at 1320 masl, 22°C average temperature and 75 percent relative humidity. 50 trees were selected at random, then one branch per tree containing 30 coffee cherries 150 days old was also chosen. Cherries were covered with entomological sleeves and infested with 250 adult CBBs. Twelve hours later the adult parasitoids were released within the sleeve. Development of life stages was daily recorded during 48 days, dissecting 25 parasitized borers per day in order to record found parasitoids state. Life cycle was determined according to the each new biological stage appearance. The adult wasp lived for 2.5 days. Duration of the immature stages was as follows: eggs 5 days; larvae I, 5 days; larvae II, 6 days; larvae III, 12 days; pupae 15 days. Life cycle from egg to adult was 43 days and from adult to emergence was 3 days. It was found that P. coffea relation 1:1 CBB: wasp used in this research produced superparasitism, and up to 17 larvae were observed within one adult borer.
