Comparative toxicology of the pyrethroid insecticides.
Physical properties that influence the environmental disposition and subsequently affect bioavailability of the compounds in water, soil, air, produce, and nontarget species are also instrumental in determining the impact of current and future synthetic pyrethroid insecticides. Expand
Toxicokinetics and Toxicodynamics of Pyrethroid Insecticides in Fish
Studies with permethrin, cypermethrin and fenvalerate have established that rates of metabolism and elimination in rainbow trout are significantly lower than those reported for birds and mammals, and variations in toxicodynamics are also crucial in evaluating pyrethroid selectivity. Expand
Fumigation toxicity of monoterpenoids to several stored product insects
Three naturally occurring monoterpenoids, the ketones pulegone, l -fenchone, and the aldehyde perillaldehyde, were selected for further study and were effective against T. castaneum in the fumigation assay; however the toxicity was relatively low in comparison to dichlorvos. Expand
Organic amendments to enhance herbicide biodegradation in contaminated soils
Abstract. Pesticide contamination of soil and groundwater at agricultural chemical distribution sites is a widespread problem in the USA. Alternatives to land-farming or solid waste disposal includeExpand
Environmental fate and effects of Bacillus thuringiensis (Bt) proteins from transgenic crops: a review.
Assessment of the nontarget effects of Bt protein toxins indicates that there is a low level of hazard to most groups of nontarget organisms, although some investigations are of limited ecological relevance. Expand
Acute toxicity and behavioral effects of chlorpyrifos, permethrin, phenol, strychnine, and 2,4-dinitrophenol to 30-day-old Japanese medaka (Oryzias latipes)†
The behavioral toxicology bioassay may be valuable in comparing and predicting the mode of action of new or unknown toxicants in this species of fish. Expand
Subacute Effects of Cry1Ab Bt Corn Litter on the Earthworm Eisenia fetida and the Springtail Folsomia candida
It is indicated that there is little direct hazard from Bt corn leaf material to E. fetida and F. candida but that differences in nutritional parameters of the Bt lines and the isolines may lead to differences in the effects on nontarget organisms. Expand
Phytoremediation—An Overview
A better understanding and appreciation of the potential mechanisms for removing contaminants from the root zone and the interaction between plants, microorganisms, and contaminants will be useful in extending the application of phytoremediation to additional contaminated sites. Expand
Insecticidal activity of monoterpenoids to western corn rootworm (Coleoptera: Chrysomelidae), twospotted spider mite (Acari: Tetranychidae), and house fly (Diptera: Muscidae).
The results with thymyl ethyl ether, one of the synthetic derivatives of thymol, showed a potential of derivatization to reduce monoterpenoid phytotoxicity. Expand
Insecticidal properties of monoterpenoid derivatives to the house fly (diptera: Muscidae) and red flour beetle (coleoptera: Tenebrionidae)
Fluoroacetates of cyclic monoterpenoids were the most effective house fly fumigants, followed by acetates, and trichloroacetates, which were both more insecticidal and more effective than haloacetates in the topical, red flour beetle fumigation and ovicidal bioassays. Expand
