| description | The first detection of the spittlebug Prosapia simulans (Walker) (Homoptera; Cercopidae) for Colombia in 1999 was a warning for ranchers and sugar cane growers in the Cauca Valley, where it already has achieved economic levels in Brachiaria. Despite its importance in pastures and cane in Central America, little is known about its biology. In order to obtain the foundation necessary to advance in its management, morphological measurements were used to recognize the life stages. To quantify the life cycle, observations were made of eggs in petri dishes under incubation, and the nymphs and adults on potted host plants. To establish oviposition sites, eggs were recovered from groups of females maintained in pots with different substrates. As with other species of spittlebugs, the eggs of P. simulans passed through four morphologically distinguishable developmental stages, the nymphs passed through five instars, and the adults showed sexual dimorphism. The duration of the egg stage was 18 ± 1,3 days, the nymphs 45,6 ± 5,4 days, and the mean longevity of the adults was 16,5 days, for a total life cycle of 71,9 days. An additional study confirmed a high incidence of diapause in eggs from the field (69,8% in the period of January-May 2000) where egg eclosion was extended up to 128 days. Females exhibited a preference for the stem as an oviposition site with 82,7% of the eggs recovered. In contrast with other species of the spittlebug complex in Colombia, P. simulans has a long life cycle and prefers the stem over soil as oviposition substrate. So far, the presence of P. simulans is limited to four localities of the Cauca Valle. |

La primera detección del salivazo Prosapia simulans (Walker) para Colombia en 1999, fue una voz de alerta para ganaderos y cañicultores del Valle del Cauca donde ya alcanza niveles económicos en Brachiaria. A pesar de su importancia en pastos y caña en Centroamérica, se conoce poco sobre su biología. Con el fin de obtener los fundamentos necesarios para avanzar en su manejo, se hicieron mediciones morfológicas para reconocer los estados de desarrollo. Para cuantificar el ciclo de vida, se observaron los huevos en cajas de petri bajo incubación, y las ninfas y los adultos en materas del hospedero. Para establecer los sitios de oviposición se recuperaron los huevos de grupos de hembras mantenidos en materas con diferentes sustratos. Al igual que otras especies del salivazo, los huevos de P. simulans pasaron por cuatro fases de desarrollo morfológicamente distinguibles, las ninfas pasaron por cinco ínstares y los adultos mostraron dimorfismo sexual. La duración del estado de huevo fue 18 ± 1.3 días, las ninfas 45,6 ± 5,4 días y la longevidad media de los adultos 16,5 días para un ciclo de vida toLtl de 71,9 días. Un estudio adicional confirmó incidencia alta de diapausa en huevos provenientes del campo (69.8% en el período enero-mayo 2001) cuando la eclosión se extendió hasta 128 días. Las hembras exhibieron una preferencia por el tallo como sitio de oviposición con 82,7% del total de los huevos recuperados. En contraste con otras especies del complejo salivazo en Colombia, P. simulans tiene ciclo de vida largo y prefiere el tallo como sustrato de oviposición. Hasta la fecha, la presencia de P. simulans en Colombia esta limitada a cuatro localidades del Valle del Cauca. 2003 2014-10-02T08:33:29Z 2014-10-02T08:33:29Z Journal Article https://hdl.handle.net/10568/44246 es Open Access application/pdf |
