The common name may or may not be part of the pesticide’s trade name–which is the big name you first see when you look at a product on the shelf, or hear in advertisements. Piperonyl butoxide has negligible toxicity in its own right at the doses used, inhibits metabolizing enzymes in insects and mammals, increasing the toxicity of pyrethrins and pyrethroids to target and nontarget species. At least 2 years if properly packed and stored. No cases were included in the handler database. The introduction of light-stable pyrethroids in the early 1970s permitted to control numerous pests of agricultural significance. for allethrin, <23 tons a.i. The classes are herbicides (H), insecticides (I), fungicides (F), and other chemicals (O). and the Institute for Environmental Toxicology, Michigan State
Although Rohwer's announcement applied the name allethrin to the "substantially pure" chemical those in the insecticide industry have urged that it mean 100 percent material (Moore 11). Examples include allethrin, resmethrin, permethrin, cyfluthrin or esfenvalerate. Allethrin was the first pyrethroid. Allethrin. The pyrethroid toxicity change is a result of increased accumulation of parent compound and increased nerve sensitivity at lower temperatures (Harwood et al., 2009). Seizures are rare in most species, but are common in cats treated with spot-on products intended for dogs, or that are in close contact with dogs treated with such products. It is possible that stress to the osmoregulatory system may be a secondary mode of toxicity of pyrethroids in fish (Di Giulio and Hinton, 2008). --- 275 30 The trade name is Pynamin. Allethrin is a potent insecticide and is widely used as a mosquito repellent. Depolarizing after-potential is gradually increased after application of type I pyrethroids such as tetramethrin and allethrin, and reaches the threshold membrane potential for generation of action potentials (Lund and Narahashi, 1981a, b; Narahashi, 1962; Vijverberg et al., 1982). Daily oral administration of deltamethrin to rats for 15 days also reduced learning and memory measured in a Y maze using a negatively reinforced visual discrimination response (Husain et al., 1996). Cyclopropanecarboxylic acid, 2,2-dimethyl-3-(2-methyl-1-propenyl)-, 2-methyl-4-oxo-3-(2-propenyl)-2-cyclopenten-1-yl ester spray. A 3% formulation was also a sensitizer in the Buehler assay.

Road, Kolkata. There are some species differences in in vitro microsome oxidation sites of allethrin between rats and mice: rat microsomes appear to preferentially oxidize the trans-methyl group of the isobutenyl moiety. flying or crawling insects. The 96Â h LC50 values determined for rainbow trout and bluegill sunfish were 2.7Â Âµg/L and 13.0Â Âµg/L, respectively (U.S. EPA, 2007). David M.

Be sure to read the label. Permethrin acute toxicity values (96Â h LC50) for various freshwater and saltwater fish species were summarized by Smith and Stratton (1986) as follows: 1.1Â Âµg/L for channel catfish, 6.4, 7.0, and 9.0Â Âµg/L for rainbow trout, 8.5Â Âµg/L for largemouth bass, 12.0Â Âµg/L for Atlantic salmon, 15.0 Âµg/L for mosquitofish, and 15.6Â Âµg/L for fathead minnow. Pyrethroids are excreted in urine, feces, and milk. There are a large number of insecticides of this class on the market. They are effective against a wide range of chewing, sucking, and boring insects, particularly Coleoptera, Diptera, Heteroptera, Homoptera, Lepidoptera, Orthoptera, and Thysanoptera species in many crops (e.g., cereals, citrus, corn, cotton, fruits, hops, grapes, oilseed rape, potatoes, soya beans, sugar beet, vegetables, forestry, and ornamentals). Allethrin had 96Â h LC50 toxicity values of 17.5 Âµg/L, 22.2Â Âµg/L >30.1Â Âµg/L, and 80Â Âµg/L for rainbow trout, Coho salmon, channel catfish, and fathead minnow (bio-allethrin), respectively (Smith and Stratton, 1986). Case 94-138 in the handler database (a formulation of allethrin and piperonyl butoxide) involved irritation on direct accidental contact. Pyrethroids are nonsystemic insecticides (i.e., no uptake through leaves and roots) with contact and stomach action and a rapid knockdown effect.

Metabolism When allethrin labeled with 14C in the acid moiety or with 3H or 14C in the alcohol moiety was orally administered to rats at 1â5Â mg/kg, the 14C and 3H derived from the acid and alcohol moieties were excreted into the urine (47â51%) and feces (27â29%) within 48Â h after administration.

On the other hand, the major oxidation sites by mouse microsomes are the trans-methyl group of the isobutenyl group, the methylene position of the allyl group, and the 7,8 double bond of the acid moiety (Class et al., 1990). Michael OâMalley, in Hayes' Handbook of Pesticide Toxicology (Third Edition), 2010. Retrieved October 26, 2005. Examples of Type I pyrethroids and Type II pyrethroids are: Pyrethrins and pyrethroids are often formulated with potentiating substances, of which piperonyl butoxide is perhaps the best known. S-Bioallethrin was a good substrate in vitro for rat CYP2C11, 3A1, and 3A2 and for human CYP2C8 and 2C19 (Scollon et al., 2009). Reported tralomethrin 96Â h LC50 values were 1.6Â Âµg/L for rainbow trout, 2.48Â Âµg/L sheepshead minnow, and 2.8Â Âµg/L for bluegill sunfish (U.S. EPA, 2000). Another structural form, the d-trans-
