Insecticide detoxification in the navel orangeworm Amyelois transitella (Lepidoptera: Pyralidae)
… cytochrome P450 monooxygenase (P450) inhibitor piperonyl butoxide and the glutathione-S-transferase (GST) inhibitor diethyl maleate (DEM) on the toxicity of the insecticides azinphos-methyl, chlorpyrifos, chlorantraniliprole, β-cyfluthrin, and bifenthrin to first instar A. transitella larvae …

The effect of eight tensides on the toxicity of diazinon topically applied to the male German cockroach
… Solvent, and diazinon in Stoddard's Solvent plus piperonyl butoxide. Five of the tensides formed emulsions that were similar in toxicity to diazinon in Stoddard's Solvent. These were, in order of decreasing L050 's, Bio Film, Tween 80, hexadecyltrimethyl ammonium bromide (HAB), Multi-Film X-77, …

Impacts of organic and conventional neurotoxic pesticides on a pest and a pollinator in almond agroecosystems (Prunus dulcis)
… cytochrome P450 monooxygenase (P450) inhibitor piperonyl butoxide and the glutathione-S-transferase inhibitor diethyl maleate on the toxicity of the insecticides acetamiprid, clothianidin, and spinosad (a natural fermentation product made up of a mixture of Spinosyn A and D) were assessed in a …

Pesticide Mixtures Induce Immunotoxicity: Potentiation of Apoptosis and Oxidative Stress
… malathion (an organophosphate) and piperonyl butoxide (PBO; a synergist). Based on minimum cytotoxicity (> LC25), the following concentrations were chosen for the pesticide mixture studies: 70μM lindane (Lind), 50μM malathion (Mal) and 55μM PBO. In the AlamarBlue cytotoxicity …

The cabbage whitefly, aleyrodes Proletella: causes of outbreaks and potential solutions
… populations. Bioassays with the synergist piperonyl butoxide provided no evidence of mixed-function oxidase or associated nonspecific esterase involvement in pyrethroid resistance. Attempts to sequence the sodium channel gene of susceptible and resistant whiteflies to check for target-site …

Symbiont-Mediated Modification of Mosquitocide Toxicity in the Dengue Vector, Aedes aegypti
… Aedes aegypti. The insecticide synergists piperonyl butoxide (PBO), triphenyl phosphate (TPP), and S,S,S-tributyl phosphorotrithioate (DEF) were used to examine the metabolic detoxification and toxic action of the two mosquitocides in mosquito larvae. A significant increase in the toxicity …

Molecular Definition of Cytochrome P450 -Mediated Multiple Resistance in Helicoverpa Zea
… resistance to the insecticide cypermethrin. Piperonyl butoxide (PBO) synergism and biochemical assays demonstrated that cytochrome P450s are responsible for the documented cross-resistance and that metabolism of these two compounds is mediated by at least one P450. Closely related P450s in …

Differential tolerance of corn hybrids to metolachlor and its regulation by the safener benoxacor
… herbicide tolerance. The monooxygenase inhibitor piperonyl butoxide (PBO) acted synergistically with EPTC on 8 of the tested corn hybrids. A Similar antagonism by the oxygen evolving compound calcium peroxide provided additional evidence for the importance of oxidative processes in EPTC tolerance …

Covalent Binding and other Mechanisms of Primaquine Toxicity
… metabolism inhibitors (SK&F-525A, metyrapone and piperonyl butoxide), and sulfhydryl-contai ni ng compounds were added to the incubation system. Conversely, the inhibitory effect of inhibitors was not shown on in vivo binding; also induction with phenobarbital decreased the extent of covalent …

Toxicity of mycotoxins to insects and underlying molecular and biochemical mechanisms
… Enhancement of the toxicity of AFB1 by piperonyl butoxide, a P450 inhibitor, indicates a role for P450s in AFB1 detoxification in honey bees. Extracts of propolis, a complex mixture of plant-derived chemicals that contains many flavonoids and other phenolic compounds, similarly …
