Artificial feeding in Boophilus microplus (Acari:Ixodidae) through micropipettes.
Newly molted Boophilus microplus females obtained in a laboratory at 30 degrees C and environmental relative humidity (RH) were employed. An original device was used to hold ticks during feeding. Three groups of 15 ticks each were created: unfed, fed with heparinized blood, and fed with defibrinated blood. Ticks were weighed before and after feeding. Females were restricted by group in three isolators attached on the skin of a bovine. Ten sexually competent males were added to each isolator. Time of coupling, tick mortality, time of detachment, and weight of engorged ticks were determined. Engorged females were incubated at 30 degrees C and 100% RH. Periods of nonparasitic phase, laying efficiency, and fertility of eggs were noted. There were no statistical differences between the three groups. This means that feeding with micropipettes does not affect the non-parasitic phase of B. microplus, the differences between heparinized and defibrinated blood are not significant.
