Imidacloprid toxicity may occur through incorrect dosing, or from accidental ingestion when the animal licks the site of application. Symptoms of toxicity include fatigue/lethargy, convulsions, breathing problems, unstable gait, tremors, and cramps. Very toxic to aquatic life with long lasting effects. Imidacloprid has moderately low toxicity to fish, but is very toxic to aquatic invertebrates. Persistence and Degradability: Imidacloprid is not readily biodegradable but will not accumulate in soils or water. Half-life in soil is 49- 190 days. Bioaccumulative Potential:No information available
imidacloprid.5 In honeybee, imidacloprid exhibits a high toxicity. At 48h, oral and contact LD 50 val-ues are 5 and 25ng per bee, respectively.6 Studies on the acute toxicity of imidacloprid have revealed important characteristics.7 (1) After oral exposure, the dose-mortality relation presents a multi-phase proﬁle with ascending and ... In the US, neonicotinoid pesticides were first registered by the US EPA in the 1990s. Currently registered neonicotinoids active ingredients include imidacloprid, thiamethoxam, clothianidin, dinotefuran, acetamiprid, thiacloprid, nitenpyrem.
Imidacloprid treatment reduced short-term learning by 87% and memory retention by 85% in comparison with control bees. Imidacloprid therefore impairs the ability of honey bees to associate a naturalistic predation stimulus – biting – with floral odor compounds. Such learning should enhance bee survival,... We know that neonicotinoid insecticides are no-good for bees and other pollinators, even at very low levels of exposure. We know the major neonic — imidacloprid (Admire®) — is the single most acutely toxic pesticide to bees ever discovered, narrowly edging out the former #1 methyl parathion.
Apr 14, 2011 · Acute Toxicity Testing and Ecotoxicity Summary: Single-dose toxicity testing indicates that d-limonene is highly toxic to worms, fish, and other aquatic organisms but low in toxicity to mammals and birds. It is assumed that it is highly toxic to bees and other insects because it is an active ingredient for insecticides. For Imidacloprid: Imidacloprid is considered to be of minimal carcinogenic risk. There were no carcinogenic effects in a 2-year carcinogenicity study in rats fed up to 1,800 ppm imidacloprid. Reproductive toxicity: No data for the product. Not considered to be toxic to reproduction.
