Description of Eggs of Anastrepha curitis and Anastrepha leptozona (Diptera: Tephritidae) Using SEM

Egg morphologies of Anastrepha curitis Stone and Anastrepha leptozona Hendel are described using scanning electron microscopy. Eggs were dissected from females captured in McPhail traps in Manaus and Presidente Figueiredo in the state of Amazonas, Brazil. Eggs of A. curitis are very long and have no aeropyles but show a seemingly porous surface on the anterior pole. Eggs of A. leptozona are robust. Eggs of both species are smooth and have no chorion ornamentation, reticulation, or protuberances. The micropyle is located at the apex of the anterior pole of the egg for both species studied. No distinct respiratory horn was detected either in A. curitis or A. leptozona. Diagnostic characters include egg length and presence versus absence of a porous surface on the anterior pole.
