Resumo
The objective of this study was to investigate the
influence of initial weight and year season on egg
conversion of Boophilus microplus females. The
reproductive efficiency index (REI) of 411 Boophilus
microplus engorged females weighing between 31 and 360
mg was correlated to their initial weights. To evaluated the
seasonal effect on this biological parameter, biweekly,
during two year, the REI was calculated on ten engorged
females ticks weighing more than 150 mg and maintained in
an incubator. A curvilinear relation was observed between
the females weight and their REI. Females weighing from
150 to 360 mg had higher REI’s (varying from 44,9% to 51,4%)
than those lighter which presented a lower conversion
capacity (varying from 31,4% to 39,0%). The reproductive
efficiency varied seasonally, that is, significantly higher index
were observed in fall/winter (47,6% to 58,3%) months than
in spring/summer months (40,2% to 43,6%).
