Morphology and protrusionretraction of the female genital chamber of Phyllophaga obsoleta (Coleoptera: Melolonthidae)
The females of Phyllophaga obsoleta (Blanchard) (Coleoptera: Melolonthidae) have a great agricultural importance in Mexico. They display a sexual calling behavior, that expose a bag-like structure on the abdominal tip, wich causes them to attract the males. The content of this structure has been ext...

| description | The females of Phyllophaga obsoleta (Blanchard) (Coleoptera: Melolonthidae) have a great agricultural importance in Mexico. They display a sexual calling behavior, that expose a bag-like structure on the abdominal tip, wich causes them to attract the males. The content of this structure has been extracted and confirmed his biological activity by wind tunnel and electroantenography bioessays. Nevertheless, their morphologic characteristics have not been studied yet. For that reason in the present study, the P. obsoleta abdominal terminalia were characterized morphologically and protrusion-retraction mechanism of bag-like structure was studied. Longitudinal dissections of the abdominal terminalia were analyzed with stereoscopic microscopy. The bag-like structure is the protractile genital chamber (PGC) of Melolonthidae females and its protrusion and retraction is related to the activity of lateral sterno-sacular muscles with ventral sterno-sacular muscles, as well as for intersegmental membranes VIII and IX. They should be involucrated in protrusion and retraction PGC mechanisms |

Phyllophaga obsoleta llamado sexual cámara genital protrusión retracción The females of Phyllophaga obsoleta (Blanchard) (Coleoptera: Melolonthidae) have a great agricultural importance in Mexico. They display a sexual calling behavior, that expose a bag-like structure on the abdominal tip, wich causes them to attract the males. The content of this structure has been extracted and confirmed his biological activity by wind tunnel and electroantenography bioessays.

The bag-like structure is the protractile genital chamber (PGC) of Melolonthidae females and its protrusion and retraction is related to the activity of lateral sterno-sacular muscles with ventral sterno-sacular muscles, as well as for intersegmental membranes VIII and IX. They should be involucrated in protrusion and retraction PGC mechanisms Las hembras de Phyllophaga obsoleta (Blanchard) (Coleoptera: Melolonthidae), una de las especies de mayor importancia agrícola en México, presentan un llamado sexual en el cual exponen una estructura en forma de bolsa del ápice abdominal y provocan la atracción de los machos. El contenido de esta estructura se ha extraído en estudios previos con diferentes disolventes y se ha confirmado su actividad biológica mediante bioensayos con túnel de viento y electroantenografía. Sin embargo, las características morfológicas de esta bolsa no han sido estudiadas. Por ello, en el presente trabajo se caracterizó morfológicamente los terminalia del abdomen femenino de P. obsoleta y se estudió el mecanismo de protrusión-retracción de la estructura en forma de bolsa. Se realizaron disecciones longitudinales de los terminalia del abdomen de hembras para su análisis con microscopía estereoscópica. Se encontró que la bolsa es la cámara genital protráctil (CGP), propia de las hembras de Melolonthidae y que se encuentra flanqueada por músculos esterno-saculares laterales y esternosaculares ventrales, así como de membranas intersegmentales VIII y IX. Músculos y membranas podrían estar involucrados en los procesos de protrusión y retracción de la CGP.
