INTRODUCTION Like all living things, cattle ticks have the ability to overcome adversity in order to survive. They can adapt genetically over time so that they and their offspring build up resistance to the normal tick treatments used. This is known as tick acaricide (chemical) resistance. The prolonged or incorrect use of tick chemicals can lead to resistance in ticks, enabling the ticks to to...

Acute manifestations of Organophosphate Compound (OPC) poison are due to effect cholinergic excess. Others are intermediate syndrome [IMS], organophosphate induced delayed neuropathy [OPIND] and chronic organophosphate induced neuropsychiatric disorder [COPIND]. All these manifestation have specific period of occurrence and duration. There are very sparse reports of toxic demylination due to OP...

background:  scabies is an ectoparasitic infection, which occurs because of direct skin-to skin contact. the ideal treatment modality is still unclear and further research on this topic is warranted. the aim of the study was to com­pare the efficacy and safety of the topical scabicides: permethrin, crotamiton and sulfur ointment. methods: fifty four patients with diagnosed scabies were randomly...

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...

Although Apis mellifera, the western honey bee, has long encountered pesticides when foraging in agricultural fields, for two decades it has encountered pesticides in-hive in the form of acaricides to control Varroa destructor, a devastating parasitic mite. The pyrethroid tau-fluvalinate and the organophosphate coumaphos have been used for Varroa control, with little knowledge of honey bee deto...

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....
