Infestations with the cattle tick, Rhipicephalus microplus, constitute the most important
ectoparasite problem for cattle production in tropical and subtropical regions worldwide …

The development of acaricide resistance in ticks infesting cattle is a major problem in the
livestock industry in tropical and subtropical regions worldwide. To determine the current …

Acaricide resistance is a major obstacle to the control of Rhipicephalus microplus.
Historically, the indiscriminate use of chemical compounds has contributed to the selection …

Ticks and the diseases they transmit cause great economic losses to livestock in tropical
countries. Non-chemical control alternatives include the use of resistant cattle breeds …

The ending of the nineteenth-century was characterized by an escalation of ticks and tick-
borne diseases that resulted in the death of many cattle. This necessitated the search for an …

The mortality of 14–21-day-old Rhipicephalus (Boophilus) microplus larvae, and the
mortality and fertility of groups of engorged adult females exposed to different concentrations …

The present study was based on assessments of the antiparasitic activities to determine the
efficacies of leaf hexane, chloroform, ethyl acetate, acetone and methanol extracts of Aegle …

This study was designed to investigate the susceptibility/resistance of Rhipicephalus
(Boophilus) annulatus to commercial deltamethrin 5%. The work was based on in vitro …

Strategies based on the use of chemicals were developed to control pests and mitigate their
impacts on human and animal health and agriculture. In Brazil and Australia alone, the …

In this article we present a new bioassay to assess the resistance status of ticks to
acaricides. The Larval Tarsal Test (LTT) is a sensitive, highly time-effective in vitro test. It …
