The residue of imidacloprid in the nectar and pollens of the plants is toxic not only to adult honeybees but also the larvae. Our understanding of the risk of imidacloprid to larvae of the honeybees is still in a very early stage. In this study, the capped-brood, pupation and eclosion rates of the honeybee larvae were recorded after treating them directly in the hive with different dosages of i...

Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae), a pest native to China and Korea, was discovered in North America in 1996. Currently, the only reliable strategy available for eradication and control is to cut and chip all infested trees. We evaluated various doses of the systemic insecticides azadirachtin, emamectin benzoate, imidacloprid, and thiacloprid for control of A. gl...

In the greenhouse, survival of adult green lacewing, Chrysoperla carnea Stephens (Neuroptera: Chrysopidae), was reduced after feeding on flowers from plants treated with a soil application of imidacloprid (Marathon 1% G, label rate and twice label rate). Percent survival for C. carnea at 10 d was statistically different between treatments and controls: 79% for untreated flowers, 14% for label r...

Pesticides are known to interfere with the biochemical processes of plants, lowering their food quality. The effects of imidacloprid insecticide (a very commonly used pesticide on vegetables) on some biochemical quality control parameters and some enzyme systems (CAT, PPO and POD) were studied. Estimation of imidacloprid residues in potatoes was done by HPLC. It was observed that insecticide tr...

The systemic insecticide imidacloprid may be applied to deciduous trees for control of the Asian longhorned beetle, an invasive wood-boring insect. Senescent leaves falling from systemically treated trees contain imidacloprid concentrations that could pose a risk to natural decomposer organisms. We examined the effects of foliar imidacloprid concentrations on decomposer organisms by adding leav...

Imidacloprid, a neonicotinoid pesticide, was used extensively to control whitefly (Bemisia tabaci) on tomato crop worldwide. Current study aimed to determine residue amounts of imidacloprid in tomato fruits after different time intervals of application and to evaluate their detrimental effects on white albino rats. Results revealed that the initial deposit (residue amount after 1 h of last spra...

Two experiments were conducted testing for lethal and sublethal effects of the transgenicproteinsCry1Acandchitinase, and thechemical seedand soil treatment imidaclopridonbumble bees (Bombus occidentalis Greene and B. impatiens Cresson, Hymenoptera: Apidae). In the Þrst experiment, B. occidentalis colonies were exposed to realistic residue levels of Cry1Ac, chitinase, and imidacloprid found in p...

Imidacloprid is a systemic insecticide used widely in controlling mites, mealy bugs and other related pests in fruits, vegetables and tea. The dissipation behaviour of imidacloprid residues in green tea shoots, made tea and its transfer potential from made tea to infusion in hot water was studied. Analysis in tea matrices of imidacloprid was carried out using high-performance liquid chromatogra...

Behavior was altered and survivorship was reduced when parasitoids, Anagyrus pseudococci (Girault) (Hymenoptera: Encyrtidae), were fed flowers from buckwheat, Fagopyrum esculentum L. (Polygonaceae), treated with soil applications of imidacloprid (Marathon 1% G). Parasitoids at 1 d had significantly reduced survivorship of 38 +/- 6.7% on label rate and 17 +/- 4.2% on twice label rate compared wi...

Field-based bioassays and residue profile analysis were used to determine the relative importance of lethal and sublethal effects of imidacloprid on adult Japanese beetle, Popillia japonica Newman, in blueberries, Vaccinium corymbosum L. Field-based bioassays assessed adult mortality and knockdown, and fruit and leaf injury from Japanese beetles exposed to 4-h and 7-d field-aged residues of imi...
