THE INFLUENCE OF FASTING ON THE FERTILITY OF DERMANYSSUS GALLINAE (DE GEER, 1778) (ACARI, DERMANYSSIDAE)

ABSTRACT

The objective of the present study was to evaluate the influence of fasting on the fecundity of D. gallinae. Females were maintained in tubes in order to feed on a young bird and then were kept fasting for 1 to 12 days. The results demonstrated that females laid eggs up to the 11th day. The number of eggs laid ranged from 1 to 8, and the greatest means were obtained in females kept up to 8 days fasting. The greatest percentage of eggs laid occurred up to the 3rd day of fasting, with a decrease from the 4th to the 12th day.
