Francisco Sánchez-Bayo et al.
Ecotoxicology (London, England), 21(3), 667-680 (2011-11-29)
Assessment of ecological impacts of toxicants relies currently on extrapolation of effects observed at organismal or population levels. The uncertainty inherent to such extrapolations, together with the impossibility of predicting ecological effects of chemical mixtures, can only be resolved by
Y Takada et al.
Journal of economic entomology, 94(6), 1340-1343 (2002-01-05)
The toxicity of six insecticides, acephate, methomyl, ethofenprox, cartap, chlorfluazuron, and Bacillus thuringiensis (Bt) was tested on different developmental stages of the egg parasitoid, Trichogramma dendrolimi (Matsumura). Each of the insecticides tested showed different degrees of toxicity to the parasitoid

Pyrethroid residues in traditional Chinese medicines have been a serious threat to the health and treatment of patients. However, because of the matrix complexity of traditional Chinese medicine, the detection of pyrethroid residues remains a challenge. Therefore, we developed a

The Journal of toxicological sciences, 37(2), 297-306 (2012-04-03)
To investigate the liver tumor-promoting effects of etofenprox (ETF), a pyrethroid-like insecticide, 6 week-old male F344 rats were given an intraperitoneal injection of N-diethylnitrosamine (DEN). After 2 weeks from the DEN treatment, 12 rats per group received a powdered diet
Soil and glass surface photodegradation of etofenprox under simulated California rice growing conditions

Dae-Hyun Yoo et al.
Journal of insect science (Online), 13, 2-2 (2013-07-25)
The toxicities of 10 insecticides were examined against late third instar Culex tritaeniorhynchus Giles (Diptera: Culicidae) using the direct-contact mortality bioassay. Six geospatially-distant field mosquitoes were collected from Chuncheon-si, Hwaseong, Seosan. Jeonju, Daegu, and Busan in the Republic of Korea.

To evaluate the insecticide susceptibility status of Aedes aegypti (L.) in Colombia, and as part of the National Network of Insecticide Resistance Surveillance, 12 mosquito populations were assessed for resistance to pyrethroids, organophosphates and DDT. Bioassays were performed using WHO

The pyrethroid insecticide etofenprox is of current interest to rice farmers in the Sacramento Valley owing to its effectiveness against the rice water weevil, Lissorhoptrus oryzophilus Kuschel. This study aimed to describe the partitioning of etofenprox under simulated rice field
T Jeyalakshmi et al.
Indian journal of experimental biology, 50(6), 439-442 (2012-06-28)
Five insecticides (Bifenthrin, Deltamethrin, Etofenprox, Permethrin and Lamda cyhalothrin) recommended by WHO, at their recommended dose were compared for their efficacy and wash resistance through bioassay against mosquito vectors, Culex quinquefasciatus, Aedes aegypti and Anopheles stephensi. Etofenprox treated nettings exhibited
Direct determination of etofenprox using surface plasmon resonance

Polyethylene glycol 300 is commonly used as a base material for "analyte protection" in multiresidue pesticide analysis via gas chromatography-mass spectrometry. However, the disadvantage of the co-injection method using polyethylene glycol 300 is that it causes peak instability in α-cyano

Parasitology research, 114 Suppl 1, S7-18 (2015-07-15)
The susceptibility of 12 field-collected isolates and 4 laboratory strains of cat fleas, Ctenocephalides felis was determined by topical application of some of the insecticides used as on-animal therapies to control them. In the tested field-collected flea isolates the LD50
Kunioki Hayashi et al.
The Journal of toxicological sciences, 35(1), 49-55 (2010-02-02)
We observed that first delivery was delayed when a group of paired mice fed with non-organic common rice compared to a group fed with organic rice. This led us to hypothesize that pesticides or other soil contaminants may be responsible
Jerome J Schleier et al.
Journal of economic entomology, 105(1), 85-91 (2012-03-17)
Evidence suggests that there are separate binding domains for type I and II pyrethroid insecticides on the voltage gated sodium channel of the nerve cell axon, but there are no studies that have examined the mixture toxicity of nonester pyrethroids
Marie E DeLorenzo et al.
Archives of environmental contamination and toxicology, 58(4), 985-990 (2010-03-20)
Opportunities for environmental contamination by the insecticide etofenprox are increasing as its uses expand from primarily indoor residential to rice cultivation and mosquito control. To provide toxicity data for sensitive saltwater species, effects of etofenprox were assessed using three life

Etofenprox residues were estimated by employing standardized QuEChERS technique in tomato following one application of Trebon(®) 20 % EC. The average recoveries of etofenprox on tomato for fortification levels 0.01, 0.1 and 0.5 mg/kg were observed to be 87.5 %

Photolysis is an important degradation process to consider when evaluating a pesticide's persistence in a rice field environment. To simulate both nonflooded and flooded California rice field conditions, the photolytic degradation of etofenprox, an ether pyrethroid, was characterized on an
