Abstract

The papaya fruit fly, Toxotrypana curvicauda Gerstaecker (Diptera: Tephritidae), has several known hosts apart from the commercially valuable papaya (Carica papaya L.; Capparales: Caricaceae), among them Jacaratia mexicana A. DC. (Capparales: Caricaceae), known in Mexico as cuaguayote. Most studies on the papaya fruit fly have been carried out with C. papaya and have neglected the other known host for this fly. We characterized papaya and cuaguayote fruits in which T. curvicauda oviposits in terms of color, length, hardness and thickness of flesh, total solids (as °Brix), and the section (proximal, middle, and distal) of the fruit where the eggs were deposited. Toxotrypana curvicauda females oviposited in medium-size to small but not large fruits of either papaya or cuaguayote. Moreover, females oviposited only in low–sugar content papaya fruits, and mostly (about 88%) in low–sugar content cuaguayote fruits with a small fraction (about 12%) of the eggs laid in medium-size and large fruits. The other variables had no effect on oviposition behavior. This is the first report of T. curvicauda oviposition behavior with respect to cuaguayote.

 

Sumario

La Mosca de la Fruta de la Papaya Toxotrypana curvicauda Gerstaecker (Diptera: Tephritidae) tiene varios hospederos aparte de la comercialmente importante papaya (Carica papaya L.; Capparales: Caricaceae), entre ellos Jacaratia mexicana A. DC. (Capparales: Caricaceae) conocida en México como cuaguayote. La mayoría de los estudios realizados con esta mosca han sido en C. papaya prestándole poca atención a los otros hospederos. Caracterizamos los frutos de papaya y cuaguayote que la T. curvicauda oviposita de acuerdo a su color, longitud, dureza, contenido de sólidos totales (como °Bx), y la parte del fruto (proximal, media y distal) donde oviposita sus huevecillos. Las hembras de la T. curvicauda ovipositan frutos de pequeños a medianos con bajo contenido de azúcar. Las otras variables medidas no modificaron el comportamiento de oviposición. Este es el primer reporte del comportamiento de oviposición de la T. curvicauda en cuaguayote.
