The availability of genome assemblies and other genomic resources is facilitating investigations of complex genetic traits for several species of ticks. Understanding the genetics of acaricide resistance is a priority for tick and tick-borne disease control. The synaptic enzyme acetylcholinesterase (ACE) is recognized as the target of organophosphates (OPs) and carbamates, and mutations in ACE ...

Oxydemeton-methyl, an organophosphate insecticide and acaricide produced decrease in the exploratory behaviour and prolongation of barbitone sodium-induced hypnosis after intermittent aerosol spray inhalational exposure for 1 h in rats compared to the saline control group. Further, CD50 +/- S.E.M. value for pentylenetetrazole (PTZ) and CI50 +/- S.E.M. value for electroshock (i.e. the dose of PT...

two hundred and ninty four engorged female ticks were collected from 4 different geographical regions for assessment of tick resistance against acaricide compounds.the 15-21 day- old larvae have been tested in accordance with fao recommended larvae packet test .resistant factor for each region was calculated by lc50 and lc99. minimum lc50 (0.008)and, maximum lc50 (0.024) for amitraz were seen i...

Survival of European honey bee (Apis mellifera) colonies has been threatened over the past few decades as Varroa destructor become a growing concern on near-global scale. Prominent treatment methods have included synthetic acaricides amitraz, coumaphos, and tau-fluvalinate. Since widespread resistance to these compounds noted, this study sought investigate V. in Virginia. infestation levels api...

BACKGROUND There are different materials and principles used in the construction of bed encasings. Although these covers claim to have antimite properties, they might not be mite proof. OBJECTIVE This study evaluated the effectiveness of mite penetration of these covers by using the Siriraj chamber method. METHODS Thirty-two covers collected from 9 different countries were categorized accor...

Spirodiclofen is characterized by a relatively slow acaricidal action against adult females of the two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), with reduction their fecundity (eggs laid/female) and fertility hatched/female). Exposure pre-ovipositing T. to acaricide may affect population growth, considering that high reproduction young crucial in biology this coloniz...
