Zusammenfassung: | Some reproductive parameters of adult stages of Amblyomma cajennense
ticks were studied. The capacity of virgin females to reproduce by
parthenogenesis was evaluated, during an experimental infestation, in
absence of males, on a horse ( Equus cabalus ). Ticks were spread
either completely free or in limited sites on the body of the animal.
The engorged virgin females showed longer feeding periods and lighter
body weights than those that had been fertilized. Some of these unmated
females produced smaller egg masses, which had no embryonary
development. On the other hand, females that had been inseminated
produced larger egg masses, with normal embryonary development that led
to viable larvae. Under the studied conditions, A. cajennense females
did not reproduce by parthenogenesis. |
