Five hinokitiol-related compounds (hinokitiol (beta-thujaplicin), beta-dolabrin, gamma-thujaplicin, 4-acetyltropolone and alpha -thujaplicin) isolated from the acid oil of Aomori Hiba (Thujopsis dolabrata Sieb. et Zucc. var hondai MAKINO) showed clear antifungal activity against wood-rotting fungi. These compounds have obvious insecticidal effects on termites. They also exhibited potent acarici...

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...

Efficient control of Tetranychus cinnabarinus (B.) is in challenge worldwide. Herein we report the use of an amphiphilic block copolymer, poly(ethylene oxide)-b-poly(caprolactone) (PEO–PCL), as a micellar carrier to make formulations of ricinine, a water insoluble botanical pesticide, and the tests of their physical properties and moreover the acaricidal activity on Vigna unguiculata (L). Compa...

background : the aim of this study was to investigate the ‘acaricidal effect' of zataria multiflora and ar­temisia annua essential oils on rhipicephalus (boophilus) annulatus . methods: this study was carried out in 2009 in the laboratory of parasitology of the faculty of veteri­nary medicine of shahrekord  university, west central iran. six dilutions (5, 10, 20, 40, 60 and 80 µl/cm 3 ) of both...

A study was conducted during 2009-10 to assess the toxicity of chloroform extracts of Pogostemon parviflorus (Benth.) and Polygonum hydropiper (L) against red spider mite (Oigonychus coffeae, Neitner) under laboratory condition using leaf detached method. Both the plant extracts possesed the acaricidal properties on developmental stages of red spider mite. The treatment with both plant extracts...

The control of tick species that affect animal production is vital for the economic welfare of the cattle industry. This study focused on testing the acaricidal activity of the essential oil from the leaves and stems of Tagetes minuta against several Brazilian tick species, including Rhipicephalus (Boophilus) microplus, Rhipicephalus sanguineus, Amblyomma cajennense and Argas miniatus. The chem...

Calpurnia aurea extracts are used in southern Ethiopia to protect stock against ticks. Acetone, hexane and water leaf extracts of C. aurea collected in southern Ethiopia were tested for repellent/attractant and acaricidal properties on unfed adult Rhipicephalus pulchellus ticks. In contrast to many other plant species evaluated, C. aurea extracts did not have repellent properties, but rather ha...
