Dalmatian pyrethrum (Tanacetum cinerariifolium /Trevir./ Sch. Bip.) is a perennial herbaceous plant belonging to the Asteraceae family. It is endemic to the East coast of the Adriatic Sea and its natural habitat extends from Italy to northern Albania and up in the mountainous regions of Croatia, Bosnia and Herzegovina and Montenegro. Pyrethrum fl owers yield an important insecticide, the pyreth...

Pyrethrin is an insecticide that is obtained from the Chrysanthemum flower (Pyrethrum). In this study, we examined the genotoxic effects of pyrethrin on cultured human lymphocytes using sister chromatid exchanges (SCEs) and 8-hydroxy deoxyguanosine (8-OHdG) assays. Cultures were treated with different concentrations of pyrethrin (25, 50, and 100 μg/mL), which was dissolved in in dimethyl sulfox...

The following pyrethrin and pyrethroid pesticides were determined in urine and water matrixes by liquid chromatography with diode array detection (LC-DAD): pyrethrin I, pyrethrin II, tetramethrin, baythroid, bifenthrin, fenvalerate, phenothrin, allethrin, resmethrin, cis-permethrin, and trans-permethrin. In addition, 3-phenoxybenzyl alcohol, a metabolite of various pyrethroids, was also success...

Methods are recommended and described for determining Pyrethrin I, Cinerin I, Pyrethrin II, Cinerin II and Jasmolin II with or without combination with synergists such as piperonyl butoxide, in milk, fish and meat, Lat and meat by-products of cattle, goats, hogs, horses, sheep, poultry tissues and eggs using g.l.c. arid t.l,c, It is probably adaptable to cereals, fruit and oilseeds.

OBJECTIVES Insecticides reduce vector-borne pathogen transmission but also pose health risks. In August 2005, Sacramento County, California, underwent emergency aerial ultralow-volume (ULV) application of pyrethrin insecticide to reduce the population of West Nile virus (WNV)-infected mosquitoes and thereby interrupt enzootic and tangential transmission. We assessed the association between aeri...

in southeast asia, aedes aegypti (l.) has been incriminated as principal vector of dengue viruses and ae. albopictus as the secondary vector of dengue fever. therefore, the aim of this study was to investigate the effectiveness of three for-mula tions of pyrethrin derived from tanacetum cinerariaefolium against the dengue/dengue haemorrhagic fever vectors aedes aegypti and ae. albopictus in the...

Pyrethrins are terpenoid esters derived from the flowers of Chrysanthemum cinerariifolium. The pyrethrin family includes six similar compounds containing a cyclopropane core, named pyrethrin 1 and 2, cinerin 1 and 2 and jasmolin 1 and 2. Pyrethrins both repel and kill insects by delaying the closure of voltage-gated sodium ion channels in the nerve cells. The insecticidal and insect repellent p...

Chemical insecticides application for pest control pose serious impacts on human health and environment. Nowadays, intensified efforts to find safer and environmentally friendly alternatives have resulted in identification and production of some plant-derived natural ingredients that can use against insect pests. Amongst these plants, feverfew, Tanacetum parthenium (L.) Sch.Bip., from Asteracea...

In response to an epidemic ampliÞcation ofWest Nile virus (family Flaviviridae, genus Flavivirus, WNV), the Sacramento and Yolo Mosquito and Vector Control District (SYMVCD) sprayed ultralow-volume (ULV) formulations of pyrethrin insecticide (Evergreen EC 60-6: 6% pyrethrin insecticide, 60% piperonyl butoxide;MGK,Minneapolis,MN, applied as 0.003 kg/ha [0.0025 lb/acre]) over 218 km in north Sacr...
