Susceptibility of the brown stink bug, Euschistus serous (Say), and the spined soldier bug, Podisus maculiventris (Say), to acetamiprid, cyfluthrin, dicrotophos, indoxacarb, oxamyl, and thiamethoxam, was compared in residual and oral toxicity tests. Generally, susceptibility of P. maculiventris to insecticides was significantly greater than or not significantly different from that of E. servus....

The principal objective of this study was to investigate the effect of household processing, including washing and cooking on pesticide residue levels in various food samples. For this study, 31 food materials were selected and 44 pesticide residues were monitored using the “quick, easy, cheap, effective, rugged, and safe” QuEChERS extraction-based and liquid chromatographyetandem mass spectrom...

Laboratory and semifield bioassays were conducted to determine the life-stage activity of insecticides for controlling cranberry fruitworm, Acrobasis vaccinii Riley (Lepidoptera: Pyralidae), a key lepidopteran pest of highbush blueberry, Vaccinium corymbosum L. The organophosphates azinphosmethyl and phosmet, the pyrethroid esfenvalerate, and the carbamate methomyl were lethal to all life stage...

BACKGROUND The presence of certain symbiotic microorganisms may be associated with insecticide resistance in insects. The authors compared the susceptibility of two isofemale lines, Rickettsia-plus and Rickettsia-free, of the sweet potato whitefly Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) to major insecticides from different chemical groups, including imidacloprid, acetamiprid, thiame...

Western cherry fruit fly, Rhagoletis indifferens Curran (Diptera: Tephritidae),is a major pest of sweet cherry, Prunus avium (L.) L., in the Pacific Northwest of the United States. Spinosad bait is applied weekly to kill flies before they develop eggs, but its effects on oviposition by reproductively mature flies are unknown. In this study, the main objective was to identify insecticide bait tr...

Neonicotinoids are considered safe because of their low affinities to mammalian nicotinic acetylcholine receptors (nAChRs) relative to insect nAChRs. However, because of importance of nAChRs in mammalian brain development, there remains a need to establish the safety of chronic neonicotinoid exposures with regards to children's health. Here we examined the effects of longterm (14 days) and low ...

Rapid and reliable multiresidue analytical methods were developed and validated for the determination of 6 neonicotinoids pesticides (acetamiprid, clothianidin, imidacloprid, nitenpyram, thiacloprid, and thiamethoxam) in honey. A modified QuEChERS method has allowed a very rapid and efficient single-step extraction, while the detection was performed by UHPLC/MS-MS. The recovery studies were car...

This work reports the application of a biochar (BC) derived from eucalyptus wood chips to remove pesticides (imidacloprid, acetamiprid and methomyl) water. The pseudo-second order kinetic adsorption model is best fit describing on BC. Furthermore, Langmuir correlated well with isotherm data for methomyl, while Freundlich was selected explain imidacloprid maximum capacities BC material are 32.42...

Lignin has been employed as a precursor to synthesize activated carbons with the aim of lignin-biomass revalorization. The properties these were compared, and best adsorbent was remove two emerging pollutants from water, acetaminophen acetamiprid. adsorption mechanisms pharmaceutical pesticide compounds analyzed, modeled interpreted via statistical physics models. In particular, kinetics isothe...

The paper presents the results of evaluating efficiency insecticides for 2016–2021 containing acetamiprid as an active ingredient (a.i.) and its combination with compounds from other chemical groups in protecting cereals dominant pests. It’s established that pre-sowing treatment seeds insecticidal preparation contributed to a decrease damage caused by wireworm cereal flies winter wheat up 87,0 ...
