ASTOLA MARISCAL, Sadith Zobeida  y  NARREA CANGO, Mónica. Biology and behavior of Cotesia flavipes Cameron (Braconidae) parasitoid of Diatraea saccharalis Fabricius (Crambidae). Ecol. apl. [online]. 2019, vol.18, n.1, pp.77-83. ISSN 1726-2216.  http://dx.doi.org/10.21704/rea.v18i1.1309.

Several aspects of the biology and behavior of a Cotesia flavipes line from Costa Rica, and its host Diatraea saccharalis were studied in Piura, Peru. This research was conducted in the Centro de Producción de Insectos Útiles (CPIU) of the Caña Brava Enterprise, at an average temperature of 28 °C and 60% humidity. The life cycle of Cotesia flavipes lasts 15 days; the larval period of the first, second and third stages are 3.3; 2.5 and 1.3 days respectively. Pupa lasts 5.6 days and sex ratio (M:F) is 1:3.9. Adult longevity is greater when it is fed. The pre-oviposition period and oviposition times are 37.9 minutes and 6.1 seconds, respectively. C. flavipes females parasitize 1 to 2 larvae. The adult emergency percentage is 91.2%. There are no differences in the number of age-parasitized larvae of Cotesia flavipes C. on stages IV, V and VI of Diatraea saccharalis F. Cotesia flavipes presents polygamous mating, sexual reproduction and parthenogenic reproduction of arrenotochia type. The male copulates from 5-14 females, the pre-mating ranges from 1-94 minutes and the mating time ranges from 8-21 seconds.
