Efeito do pinhão bravo (Jatropha molíssima (Pohl) Baioll) e do marmeleiro (Croton blanchetianus Baill) sobre os parâmetros reprodutivos de fêmeas ingurgitadas de Rhipicephallus (Boophilus) microplus (Acari: Ixodidae) no Semiárido Paraibano.

Abstract

The tick R. (Boophilus) microplus is the main ectoparasite of cattle, causing significant losses in cattle ranging from losses in the production of meat and / or milk to health damage, since it behaves as a vector of infectious agents such as Babesiaspp .andAnaplasmaspp, hematozoa responsible for the highest mortality rates in cattle in tropical and subtropical regions. The use of ethanol extracts of wild Pinion (J. molíssima) and Quince (blanchetianus C.) was conducted in order to verify its effectiveness and its effects on reproductive parameters teleógenas the species R. (B.) microplus. The engorged females were randomly obtained from animals of farms in the middle region of Paraiba backwoods. For each plant formed three groups with ten gravid females each, distributed as follows; Group I (ticks treated with the extract at 100%) and group II (ticks treated with the extract at 50%) representing the treated and control group III representing (ticks treated with distilled water). The tests consisted of exposing the gravid females to herbal extracts through immersion bath for ten minutes, then distribute them in Petri dishes, setting the dorsoventrally with the aid of masking tape. The observed data were evaluated by Biocarrapatocidograma and efficiency test. The plant extracts inhibited the pre-laying; laying period, and interfered with the following parameters: rate of egg production (IPO); reproductive efficiency index (REI); fertility index (FI) and (%) of mortality with treatment pinion brave 100% being very statistically superior.
