Abstract

The efficacy of an injectable microsphere formulation of ivermectin for control of B. annulatus was tested on 2 groups of 6 Hereford heifers held on separate 7-ha, tick-infested pastures in Texas, USA. Cattle in one pasture were injected subcutaneously in the neck with a controlled-release...

Abstract

A study was conducted at the USDA-ARS, Cattle Fever Tick Research Laboratory, Mission, Texas, USA, to determine the efficacy of a 0.05 and 0.1% microencapsulated permethrin formulation applied as a whole-body spray, in a standard dip vat, and in a laboratory bioassay against B. microplus on cattle. ...

Abstract

An 11.6% emulsifiable concentrate of phosmet (Prolate) was evaluated in a dipping vat to determine its stability and other characteristics pertaining to management of the product in a vat in which large numbers of cattle were processed (in Texas, USA). A separate trial was done to determine...

Abstract

Strict enforcement of cattle quarantine, developed during the national cattle fever tick eradication campaign, blocked the reintroduction and dissemination of Boophilus microplus and B. annulatus northwards from southern Texas. However, reliance on coumaphos dips and pasture vacation was now...

Abstract

A long-term field study (60 consecutive weeks in 1996-97) was conducted to determine whether a B. annulatus population could be eradicated through repeated applications of a 1% pour-on formulation of fipronil on cattle held in an infested pasture in Texas, USA. Animals treated repeatedly over time...

Abstract

A neckband and tailtag containing either amitraz or cyhalothrin K were placed on individual cattle to test the effectiveness of the devices for the control of adult Amblyomma americanum. The neckbands and tailtags were fabricated from either strips of ethylvinyl acetate containing 10% amitraz or...

Abstract

A variety of pathways exist for the introduction of nonindigenous insects, ticks, and mites of veterinary importance into the United States. The most prominent includes the natural migration of mosquitoes and flies by the flight of adults, ectoparasites entering the country on wildlife transport...

Abstract

A study was conducted to determine the efficacy of cyhalothrin and lambda-cyhalothrin as a whole-body spray and lambda-cyhalothrin as a pour-on application on cattle infested with B. microplus. A laboratory bioassay was also done with both spray formulations. Cattle were infested with all parasitic ...

Abstract

A strain of B. microplus was selected for resistance to permethrin by pressuring larvae with increasing doses (range, 0.05-0.35% a.i.) through successive generations (generations F2-F7). At the beginning of the selection process (F2), the pyrethroid resistant (PR) strain was 5.4 times more...
