The aim of this study was to evaluate the association between seropositivity to Anaplasma phagocytophilum and Borrelia burgdorferi sensu lato and the following factors: (i) type of household (rural vs. urban), (ii) use of acaricides (type and seasonality/duration), and (iii) history of tick bite (season). Blood samples were collected from all the dogs in the household and dog owners were survey...

INTRODUCTION Several arthropod pests infest strawberry crop in California and cause a significant yield loss according to Zalom, Bolda, Dara, and Joseph [1]. Strawberry is an important commercial crop and the annual report from California Department of Pesticide Regulations [2] indicates that large quantities of acaricides, fungicides, herbicides, and insecticides are applied to manage a variet...

The efficacy of an amitraz/cypermethrin pour-on preparation (1% w/v each) was tested against natural tick infestations of buffaloes, eland and blesbok in three separate trials. The eland were also treated with a 0.02% abamectin (w/v) acaricidal pour-on preparation. The amitraz/cypermethrin pour-on was effective against Amblyomma hebraeum, Rhipicephalus evertsi evertsi, Rhipicephalus appendicula...

The properties and actions of the bridged diphenyl acaricides are discussed. These pesticides, which are more or less structurally related to DDT, were the first of the specific acaricides to be developed. They exhibit remarkable properties of specificity, being primarily toxic to phytophagous mites but of very low toxicity to most nontarget species, including insects, fish, birds, and mammals....

A survey conducted in five villages in a resource-poor farming community in Qwa-Qwa, using the rapid rural appraisal technique and a questionnaire survey, showed that a significant proportion of the farmers (84%) use traditional or alternative methods to control ectoparasites, while 16% use commercial acaricides (chi2 = 7.1; P < or = 0.05). Alternative control methods included the use of used e...

The tick Rhipicephalus (Boophilus) microplus (formerly Boophilus microplus) is the major ectoparasite affecting livestock in America, Asia, Africa, and Oceania. Conventional tick control is based on the use of acaricides but immunization of bovines with tick gut proteins induces only a partial protective immune response. Based on this information, distinct research groups have explored the poss...

The adult immersion test (AIT) was used to evaluate the efficacy of acaricide molecules used for control of Rhipicephalus microplus on 106 populations collected in five municipalities in the state of Rondônia in the Brazilian South Occidental Amazon region. The analysis of the data showed that the acaricide formulations had different efficacies on the tick populations surveyed. The synthetic py...

Field trials were conducted in Northeast Spain (Aragón) to evaluate the effectiveness of two acaricides against Varroa destructor. These experiments took into account the season of the year, apiary, colony, and developmental state and strength of the colony. The acaricides used were a synthetic (amitraz, Apivar®) and a natural (formulated from Api Life Var®, thymol oil and thymol alcohol) produ...

The aim of this study was to identify mite fauna associated with soybean crops and report new species the Monsoy 8349 IPRO variety in municipality Luís Eduardo Magalhães, western region Bahia. Samplings were performed an area transgenic soybeans, subdivided into three treatments: T01, no use agricultural pesticides; T02, complete package pesticides, except for acaricides; T03, pesticides includ...
