Classificação de fêmeas de Stomoxys calcitrans (L. ) (Diptera: Muscidae), de acordo com a idade fisiológica / Classification of female of Somoxys calcitrans (L. ) (Diptera: Muscidae), according to the physiological age

ABSTRACT

With the purpose of maiking easier the determination of the physiological age of Stomosys calcitrans population, a classification based on the oocitary developtment and number of ovipositions was proposed. Female were reared under laboratory conditions, in individual cages and maintained in the presence of male for copulation. On the proper time, ovary and oviduct were removed and the stage of development was observed. Adult female were classified as 1-New emerged female, 2 - Young nuliparous female, 3 - Old nuliparous female, 4 - Uniparousfemale, 5 - Two or three ovipositions times female, and 6 - Multiparous female.
