Ticks are very important in the livestock industry. They are agents of disease causing organisms in
addition to the harm they cause to the hide of livestock. A study of some reproductive characteristics of
Rhipicephalus annulatus in the laboratory through colony culture showed that between 3140 to 5338 eggs
(p<0.05) were laid by each engorged female, of an average weight of 103 to 175 mg (p<0.05). The required
number of days for hatching of eggs was found to be 24 to 30 days (p<0.05). Percentage survival of eggs to
adult female was highest at 6.1% and as low as 0.57%. Despite the large number of eggs laid, very few larvae
survived to the adult stage even in the laboratory where biotic and abiotic factors were controlled to the
advantage of the ticks. This showed that in the wild where both biotic and abiotic conditions are very unstable,
survivability would be very minimal. We concluded that as much as possible, control strategy be geared
towards the destruction of the adult females as possible.
Key words: Average, engorged, female, reproductive, survivability, weight,
