The toxic effects elicited by synthetic pyrethroids in animals are varied in degree and nature. Their relative safety to birds and mammals contrasts sharpl... SP Bradbury,JR Coats - 《Rev Environ Contam Toxicol》 被引量: 600发表: 1989年 Toxicity of Selected Insecticides and Insecticide Mixtures ...
Toxicity evaluation The pyrethrins have low toxicity to mammals, and death after exposure to pyrethrins is rare. Their lability in light and air leads to a lack of residual activity and the need for repeated applications. This has restricted the use of the natural pyrethrins in the animal health...
ToxicityLaboratory and domestic animalsPyrethrin and pyrethroid insecticides are widely used in veterinary medicine for agricultural and domestic purposes. Although pyrethrins and pyrethroids are generally regarded as safe to animals, there have been reports of systemic poisoning in veterinary species. This ...

ToxicityInsecticideAvoidance behaviourPyrethrins are natural insecticides that have been on the market for decades. In spite of that only limited data are available on the toxicity of pyrethrins to non-target animals. In our study we hypothesized that a pyrethrin-containing insecticide affects ...
The results obtained show that by suitably varying the parameters of the three extraction procedures, it is possible to obtain pyrethrin extracts for use in the production of low toxicity insecticides for warm-blooded animals and low pollution. In particular, extraction with supercritical CO2presents ...
Toxicity :The six insecticidal constituents of the extract of the pyrethrum flowers Pyrethrum (Chrysanthemum cinerariaefolium). Pyrethrins I and II are most prominent, existing in the ratio 71:21:7 for pyrethrin (I and II), cinerin (I and II), jasmolin (I and II). Pyrethrins are potent...
