Resumen
Esta investigación tuvo lugar en un laboratorio artesanal creado en el Cantón el
Triunfo - provincia del Guayas. En campo se colectaron larvas y pupas de
algunas especies de moscas Sirphydas, se llevaron al laboratorio donde se
mantuvieron para la cría y reproducción. El objetivo de este trabajo fue
determinar el ciclo biológico y la capacidad depredadora de especies de
moscas Sirphydas sobre poblaciones de áfido amarillo (Sipha flava). Para la
cría de adultos se utilizaron jaulas forradas con tela tul, para las larvas se
acondicionaron pomos de vidrio, las pupas fueron colocadas en envases
plásticos y los huevecillos en tubos de ensayo, todos bajo temperatura y
humedad controlada. Para alimentar a los adultos de moscas Sirphydas se
utilizó polen, miel y azúcar. Las hembras iniciaron la cópula cuatro días
después de su emergencia, iniciaron la ovoposición después de 3 días con un
promedio de 3 a 4 huevecillos/día. El tiempo de eclosión de huevecillos fue de
2.6 días y tuvo una fertilidad del 98%. El estado de larva y pupa fue de siete
días, los adultos tuvieron una longevidad de 14 días las hembras y 16 días los
machos. Se evaluaron 2 especies de moscas Sírfidos presentes en el cultivo
Melanostoma sp y Pseudodoros clavatus. El promedio de depredación de
áfidos para Melanostoma sp fue de 752,5 y de 829,8 para Pseudodoros
clavatus. El ciclo de vida desde huevo hasta la emergencia del adulto fue entre
16 y 17 días.
This investigation took place in an artisan laboratory created in the Canton el Triunfo - province of Guayas. In the field, larvae and pupae of some species of Syrphida flies were collected and taken to the laboratory where they were kept for breeding and reproduction. The objective of this work was to determine the biological cycle and the predatory capacity of Syrphid fly species on yellow aphid populations (Sipha flava). For the breeding of adults, cages lined with tulle cloth were used, glass knobs were conditioned for the larvae, the pupae were placed in plastic containers and the eggs in test tubes, all under controlled temperature and humidity. To feed the adults of Syrphidas flies pollen, honey and sugar were used. The females began copulation four days after their emergence, they started the oviposition after 3 days with an average of 3 to 4 eggs / day. Egg hatching time was 2.6 days and had a 98% fertility. The state of larva and pupa was seven days, the adults had a longevity of 14 days for females and 16 days for males. Two species of Syphid flies present in the culture Melanostoma sp and Pseudodoros clavatus were identified. The average aphid predation for Melanostoma sp was 752.5 and 829.8 for Pseudodoros clavatus. The life cycle from egg to adult emergence was between 16 and 17 days.
