Neonicotinoid pesticides have been widely applied for the production of fruits and vegetables, and occasionally detected in conventionally grown produce. Thus oral exposure to neonicotinoid pesticides may exist in the general population; however, neonicotinoid metabolites in human body fluids have not been investigated comprehensively. The purpose of this study is the qualitative profiling and ...

to study the molecular basis for resistance of lolium rigidum populations (from fars province) to aryloxyphenoxy propionate herbicide through dcaps method, an experiment was conducted at the biotechnology laboratory of shiraz university. eighteen populations of l. rigium suspected of herbicide resistance, from zarghan, fasa. noorabad and firoozabad areas which had survived a recomended dose of ...

Newer, selective insecticides with few negative impacts on natural enemies and competitor species are needed for effective, sustainable management of the western flower thrips, Frankliniella occidentalis (Pergande). The purpose of this study was to evaluate the impacts on natural enemies and competitor thrips species of insecticides used for control of western flower thrips in fruiting vegetabl...

Coccinella septempunctata is a nontarget beneficial arthropod and an important aphid predator in agricultural crops. In this study, the toxic effects of neonicotinoid acetamiprid on C. were investigated to determine its applicability efficacy against predator. The results toxicity test showed that second instar larvae most sensitive acetamiprid. LC50 values 1st, 2nd, 3rd, 4th 15.767, 9.412, 18....

The common pistachio psylla, Agonoscena pistaciae Burckhardt and Lauterer (Hemiptera: Psyllidae), is a key pest in pistachio orchards in Iran. Chemical control is a common method to manage this pest. Compatibility between natural enemies and pesticides is a primary concern in programs of integrated pest management of the psyllid pest. In this research, susceptibility of fifth instar nymphs of A...

The present study was carried out to assess the toxicological effect of acetamiprid, an insecticide of neonicotinoid group on clinical and serum hematobiochemical parameters of mice. The experimental animals were divided into four different groups of equal number of animals and the first group was considered as Control. It was found that acetamiprid administered @ 40 mg/kg body weight per day (...

Onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), feeding injury results in discoloration and a rough texture on cabbage, Brassica oleracea capitata (L.), leaves, and damage may occur deep inside the head. It has become a key pest of cabbage in the United States and many other countries. Previous studies have indicated poor control using insecticides. The present study identified ...

Neonicotinoid insecticides are one of the most important commercial insecticides used worldwide. The potential toxicity of the residues present in environment to humans has received considerable attention. In this study, a novel Ochrobactrum sp. strain D-12 capable of using acetamiprid as the sole carbon source as well as energy, nitrogen source for growth was isolated and identified from pollu...

The cabbage seed weevil, Ceutorchynhus assimilis (Paykull) (Coleoptera: Curculionidae) is a pest that more and more often causes large financial losses for rapeseed cultivators in Poland and other European countries. One of the reasons of these problems is the resistance of the pest to certain active substances of insecticides. The aim of the study was to assess the susceptibility level of the ...

The role of biochar as a soil amendment on the transport of acetamiprid, a widely used neonicotinoid pesticide, is little known. We conducted saturated column experiments to examine cotransport of acetamiprid and silica nanoparticles (NPs) in pure and biochar-amended sands. Retention of acetamiprid was minor in the pure sand, whereas application of biochar in the sand significantly increased re...
