Resumo: A ovogênese e a postura de ovos pode ser inibida, durante o primeiro ciclo reprodutivo de Rhodnius prolixus, por um único tratamento com etoxiprecoceno II. Esta inibição, se medida pelo crescimento dos ovócitos, maturação de ovos e ovipostura, depende da dose do composto utilizado. A produção de ovos, no entanto, pode ser parcial ou totalmente restabelecida após dois subseqüentes repastos de sangue sem a droga. Estes dados sugerem que a ação do etoxiprecoceno II sobre o corpus allatum não é irreversível em fêmeas de Rhodnius prolixus.

Estes dados sugerem que a ação do etoxiprecoceno II sobre o corpus allatum não é irreversível em fêmeas de Rhodnius prolixus.Oogenesis and oviposition can be inhibited in female of Rhodnius prolixus by means of short-term experiment (first reproductive cycle) of a single dose of ethoxyprecocene II given by ingestion. The inhibition is dose-dependent as measured by oocyte growth, egg maturation and egg deposition. In a long-term experiment (second and third reproductive cycles) egg production and oogenesis can be partially or totally re-established by subsequent blood meals without ethoxyprecocene II. These findings suggest that in female R. prolixus, damage caused to corpus allatum by ethoxyprecocene II, in certain cases, is not irreversible.Universidade Federal Fluminense.
