Resumo: | The tick Rhipicephalus (Boophilus) microplus is an important parasite in the cattle raising field due to the economic losses it causes to Brazilian herds. This parasite has two stages of life, a parasitic stage that takes place in the host body and a free-living stage that takes place on soil and vegetation. The water accumulation on the soil has a strong influence in the biology of the Ixodidae, as well as other factors such as temperature and relative humidity. The aim of this experiment was to evaluate the possible deleterious effect of water immersion in controlled conditions of R. microplus females. For that, the teleogines were immersed in water for 0, 2, 4, 6, 12, 18, 24, 30, 36, 42, 48, 60, 72, 84, 96, 108 and 120 hours, according to the treatment. After this part, the ticks were taken to an incubator to finish the egg-laying and hatching. After 30 hours of water immersion, the teleogines had done the egg-laying, however more them half of the eggs did not hatch. After 48h, half of the ticks had done the laying and the hatching rate was lower than 31%. After 84h, there were no more hatching and the treatment had 100% efficacy. After analyzing the results, we can conclude that water immersion for more than 2 hours have a negative effect on cattle ticks reproduction parameters, through alterations in the egg-laying and in the hatching. |

Este parasito apresenta duas fases de vida, uma fase parasitária que ocorre no corpo do hospedeiro e uma fase de vida livre que ocorre no solo e vegetação. O acúmulo de água no solo influencia na biologia dos ixodídeos, além de outros fatores fundamentais como a temperatura e a umidade relativa do ar. Este experimento teve a intenção de investigar a ação deletéria da imersão em água, em condições controladas, de fêmeas de R. microplus. Para isso, as teleóginas permaneceram imersas em água por 0, 2, 4, 6, 12, 18, 24, 30, 36, 42, 48, 60, 72, 84, 96, 108 e 120 horas conforme tratamento, sendo posteriormente colocadas em uma estufa climatizada para verificação da postura de ovos e eclosão das larvas. Foi observado que em um período de até 30h de imersão, as teleóginas realizaram postura, no entanto mais de 50% ovos não eclodiram. Após 48h, foi observado a postura em mais de 50% das fêmeas e a taxa de eclosão larval foi inferior a 31%. A partir de 84h não houve mais eclosão larval e o tratamento atingiu 100% de eficiência. Com base nos resultados obtidos, conclui-se que a imersão em água por um período superior a 2 horas possui efeito negativo nos parâmetros reprodutivos do carrapato bovino, através de alterações na postura e na eclosão larval.UEL2012-06-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por parescomunicacao curtaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/888910.5433/1679-0359.2012v33n3p1127Semina: Ciências Agrárias; Vol. 33 No. 3 (2012); 1127-1132Semina: Ciências Agrárias; v. 33 n. 3 (2012); 1127-11321679-03591676-546Xreponame:Semina.
