A new analytical method has been validated for determining the insecticide acetamiprid in vegetables using gas chromatography (OC) and different mass spectrometric detection techniques, such as full-scan mass spectrometry (MS), and tandem mass spectrometry (MS/MS). For this purpose, a previous extraction of the vegetable sample was carried out with ethyl acetate. In GC-MS/MS, the lowest detecta...

In UK forestry, the synthetic pyrethroid insecticides alpha-cypermethrin and cypermethrin have been used for many years to provide protection young trees from damage by large pine weevil, Hylobius abietis L. However, concerns over toxicity of these has led a search alternatives. our work, applications 0.037 g.a.i.stem–1 acetamiprid provided high levels browsing, comparable or cypermethrin, with...

Cotton whitefly, Bemisia tabaci is an important polyphagous pest worldwide. It exposed to various chemical insecticides throughout the year, resulting in rapid development of insecticide resistance. Mixtures with distinct modes action could enhance toxicity chemicals more effectively than sequences or rotations resistant populations. Bioassays were conducted study efficacy mixtures neonicotinoi...
