Effects of blood ingestion on patterns on the chorion of eggs of lutzomyia ovallesi (diptera: psychodidae)

Chorion patterns on eggs of Lutzomyia ovallesi fed on seven types of blood were studied using scanning microscopy. The results showed that the different blood sources produced no differences in the patterning. The eggs had a chorion with sinuous longitudinal bridges and a few transverse bridges that formed rectangular shapes. These results confirm that chorion patterns on the eggs of sand flies are a useful taxonomic parameter.
