          Abstract

          La especie Carmenta foraseminis insecto plaga del cacao, Theobroma cacao L., difícilmente oviposita en condiciones de cautiverio. Así que para conocer algunos aspectos de su biología se desarrolló una investigación en dos localidades del estado Aragua, Venezuela: Maracay (My) y Choroní (Ch). En Ch fueron tomadas muestras en las pilas de las mazorcas de cacao dispuestas para el desgrane, de los frutos dañados se colectaron larvas y pupas que se utilizaron posteriormente en los ensayos. Además, se hicieron las pruebas para determinar si el color (negro o blanco) y el tipo de envase afectaban la emergencia y duración de la fase adulta, al respecto no se presentaron diferencias significativas. Igualmente, se realizaron pruebas sobre el ciclo de la fase adulta, porcentaje de emergencia según el sexo, horarios matutino y vespertino. Para el análisis de datos se usaron las pruebas binomial y de ji al cuadrado (χ²) para dos proporciones, adicionalmente, se probaron diferentes recipientes y sustratos para la obtención de huevos. En My hubo diferencias significativas en las proporciones de machos y hembras emergidos. También se detectaron diferencias altamente significativas para el número de pupas que lograron alcanzar la fase adulta y el lugar de emergencia, siendo mayor la emergencia en Ch, donde no se observaron diferencias significativas con respecto a los horarios señalados, pero se consiguieron huevos en el contenedor que tenía secciones de cacao con las exuvias de las pupas de C. foraseminis.

          Translated abstract

          The species Carmenta foraseminis pest of cocoa, Theobroma cacao L., hardly oviposit in captivity. So to know some aspects of its biology research was undertaken in two locations of Aragua State, Venezuela: Maracay (My) and Choroní (Ch). In Ch samples were taken in the stacks of cocoa pods ready for shelling. From damaged fruits were collected larvae and pupae that were subsequently used in the trials. In addition, tests were made to determine if the color (black or white) and the type of container affect the emergence and duration of the adult stage, the matter did not show significant statistical differences. Similarly, tests were performed on the cycle of the adult stage, emergence percentage by sex, morning and evening hours. For data analysis were used binomial test and chi-square for two ratios, additionally, different containers were tested and substrates for obtaining eggs. In My significant differences in the proportions of males and females emerged. Also, highly significant differences were detected for the number of pupae that managed to reach the adult stage and location of emergency, emergency being greater Ch, where no significant differences were observed with respect to the times indicated, but it got eggs in the container that had sections of cocoa with pupal exuviae C. foraseminis.
