The cattle tick, Rhipicephalus microplus, is arguably the world's most economically important external parasite of cattle. Sustainable cattle tick control strategies are required to maximise the productivity of cattle in both large production operations and small family farms. Commercially available synthetic acaricides are commonly used in control and eradication programs, but indiscriminate p...

Gualamycin is a water-soluble acaricide isolated from the culture broth of Streptomyces sp. NKl^S?1*. The structure was deduced to be 1 mainly from the spectral and/or X-ray crystallographic analyses of its disaccharide 2 and aglycone portions 32). The absolute structure of the disaccharide, however, remained undetermined. Herein, we confirm the absolute structure 1 by the enantiospeciflc synth...

The prevention of tick-borne diseases is a major challenge for livestock production globally. Tick control strategies include the use acaricides, but prescribed do not achieve desired results in several countries, including Kenya. To better understand how tick treatment practices, contribute to reported failures, we assessed owners’ acaricide procurement, level knowledge about acaricides and re...

Two ladybeetles, Cycloneda sanguinea (L) and Harmonia axyridis Pallas, were exposed to leaf residues and topical applications of five acaricide formulations commonly used in citrus production in Florida. Dicofol was the only compound demonstrating no toxicity to larvae of either species, even at twice the recommended rate. Abamectin + petrolium oil was the most toxic material; leaf residues app...

Insecticides continue to be the primary means of control for ectoparasites on livestock. Intensive use of these materials has led to resistance to organochlorines, organophosphates and pyrethroids among populations of Haematobia irritans irritans, H. irritans exigua and Lucilia cuprina. Similarly, use of acaricides has led to resistance in one-host Boophilus ticks to all currently-used organoph...

the effects of three doses of spirodiclofen sc 240 in comparison with three registered ‎acaricides on citrus rust mite in western part of mazandaran province during period of 2003-‎‎2004 studied. the bcr design was used to assign four replications of seven treatments ‎‎(spirodiclofen sc 240 at doses 0.1, 0.18 and 0.27 millilitre in 1000cc water, fenproximate, ‎pyridaben, abamectin) including an...

Nonthermal air plasma, which can be generated by discharge, contains large amounts of reactive oxygen species (ROS), nitrogen (RNS) and high-energy particles. The ROS RNS have strong oxidizing properties, the particles break chemical bonds in organic compounds, a process used to degrade matter such as pesticides. In present study, effects nonthermal plasma on degradation several pesticides were...

The tomato russet mite, Aculops lycopersici (Massee, 1937) (Acari: Eriophyidae) is a common pest of tomatoes. predatory Amblyseius swirskii Athias-Henriot, 1962 Phytoseiidae), can control A. populations. To integrate biological and chemical lycopersici, side effects the lethal concentrations acaricides, as predator, on should be considered. 14 acaricides for were determined under laboratory con...
