Reproductive modes and daily fecundity of Aenasius bambawalei Hayat (Hymenoptera: Encyrtidae), a parasitoid of Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae), were elucidated in this experiment. Aenasius bambawale reproduced mainly by gamogenesis and occasionally by arrhenotokous parthenogenesis. Aenasius bambawalei females allocated far more energy sources to their own survival than to reproduction during the mid and late portions of the ovipositional period. Therefore, newly emerged adult parasitoids should be chosen for mass rearing and for use in the biological control of P. solenopsis.
Sumario
El modo de reproducción y la fecundidad diaria de Aenasius bambawalei Hayat (Hymenoptera: Encyrtidae), un parasitoide de Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae), fueron aclarados en este experimento. Aenasius bambawale se reproduce principalmente por gamogenesis y de vez en cuando por arrenotoquia, un tipo de partenogénesis. Las hembras de Aenasius bambawalei asignan muchas más fuentes de energía para su propia sobrevivencia que a la reproducción durante la parte mediana y final del período de oviposición. Por lo tanto, parasitoides adultos recién emergidos deben ser elegidos para la cría en masa y para su uso en el control biológico de P. solenopsis.
