Resumen
Esta investigación se realizó en el laboratorio de Entomología de
AGROCALIDAD cantón Guayaquil, busca determinar el ciclo biológico y
comportamiento de D. citri en dos hospederos bajo condiciones
semicontroladas. Se recolectaron insectos adultos y liberados en jaulas de
madera con dos plantas de mirto para la cría, de ahí fueron sexados y
colocados en jaulas más pequeñas, para observar el comportamiento.
Desde el instar ninfal hasta la emergencia del adulto, los insectos se
colocaron en vasos plásticos cubiertos con tul y lámina de acetato. El ciclo
biológico desde huevo hasta la emergencia del adulto fue de 16,43 y 16,58
días en Murraya paniculata y Citrus aurantifolia, y la longevidad de los
adultos en estas especies, hembras y machos, de 43,17; 33,53 y; 37,86;
35,50 días respectivamente. La hembra después de 6 días de copulada
ovoposita en las axilas de las hojas de los brotes tiernos, un promedio de 19
huevecillos/día, y 86,83% de eclosión para M. paniculata y 15 huevos/día,
con promedio de eclosión de 41,44 % para C. aurantifolia. La vida
reproductiva de una hembra fue de 10, y 6,67 días en M. paniculata y C.
aurantifolia respectivamente.
This research was carried out in the Entomology laboratory of AGROCALIDAD cantón Guayaquil, it aims to determine the biological cycle and behavior of Diaphorina citri in two hosts under semicontrolled conditions. Adult insects were collected and released in wooden cages with two myrtle plants for breeding, and then they were sexed and placed in smaller cages, to observe their behavior. Insects were placed in plastic cups from nymphal instar until adult emergence, covered with tull and acetate sheet. The biological cycle from egg to adult emergence of Murraya paniculata and Citrus aurantifolia was 16.43 and 16.58 days, and the longevity of adults of these species, females and males, of 43.17; 33.53; and 37.86; 35.50 days, respectively. The female after 6 days of copulation laid eggs in the axills of leaves of young shoots, an average of 19 eggs / day, and 86.83% of hatching for M. paniculata and 15 eggs / day with average hatching of 41.44% C. aurantifolia. The reproductive life of a female was 10, and 6.67 days in M. paniculata and C. aurantifolia respectively.
