An abamectin (ABM)-degrading bacterium, Stenotrophomonas maltophilia ZJB-14120, was isolated and identified. This strain is capable of degrading 84.82% of ABM at an initial concentration of 200 mg/L over a 48 h incubation period. This strain showed efficient biodegradation ability (7.81 mg/L/h) to ABM and high tolerance (1000 mg/L) to all macrolides ...

Degradation of Abamectin and Doramectin on Sheep Grazed Pasture
Ecotoxicology, 2005Avermectins are widely used veterinary medicines. They bind strongly to faeces in their non-metabolized form and their half-life in faeces depends on field conditions. There are conflicting data regarding the behaviour of avermectins in the environment. Therefore, we investigated the degradation of abamectin and doramectin on sheep grazed pasture under

Effects of abamectin on bullfrog tadpoles: insights on cytotoxicity
Environmental Science and Pollution Research, 2017Abamectin is one of the most used pesticides worldwide. However, investigations about its effects on amphibian populations are rare. Thus, the present study sought to investigate possible cytotoxic effects on Lithobates catesbeianus tadpoles exposed to low abamectin concentrations diluted in water.

Toxicity of Abamectin to Cockroaches (Dictyoptera: Blattellidae, Blattidae)
Journal of Economic Entomology, 1991Abamectin was fed to German cockroaches, Blattella germanica (L.), in non-choice tests. LT50s and LC50s were estimated by probit analysis. The LT50s for the German cockroach ranged from 4.4 to 1.7 d for males, from 9.0 to 2.4 d for females, and from 4.4 to 1.6 d for nymphs for bait concentrations of abamectin between 0.0025 and 0.0500%.

Persistent anthelmintic activity of abamectin injection in cattle
New Zealand Veterinary Journal, 1992The duration of the anthelmintic activity of abamectin administered by subcutaneous injection at 200 microg/kg was determined using induced infections of Haemonchus placei, Ostertagia ostertagi, Cooperia spp., and Oesophagostomum radiatum in cattle.

1989
Ivermectin and abamectin, members of the avermectin family of compounds, were introduced to the market in the 1980's as a veterinary antiparasitic drug and agricultural pesticide, respectively. Their acceptance and commercial success have been remarkable; both are highly effective and in worldwide use.

Pear, Insect Control with Abamectin, 1986
Insecticide and Acaricide Tests, 1987Abstract Sprays were applied by handgun operating at 200 psi to 13-year old pear trees. Test plots consisted of 4 single-tree replicates in a randomized block. Trees did not receive any prebloom sprays to allow PP to build. Experimental sprays were applied 24 Apr (petal fall), 17 Jun and 31 Jul.

Efficacy of abamectin injection againstDermatobia hominis in cattle
Parasitology Research, 1993The efficacy of abamectin 1%, when injected subcutaneously in cattle at a dose of 200 micrograms/kg body weight, against the larval stages (grubs) of the fly Dermatobia hominis was evaluated in two trials in endemic areas of Brazil and Argentina. Eighteen Holstein x Brahman castrated males and 16 Brahman-cross with natural infestations were used ...

Pharmacokinetics of abamectin in sheep, goat and deer
Small Ruminant Research, 2018Abstract Previous studies and anecdotal reports have generally suggested that goats and deer have higher metabolic rates of anthelmintics as compared to sheep. If this is correct then these animals are effectively under dosed if treated with the sheep dose rate.

Abamectin as a pesticide for agricultural use.
Acta Leidensia, 1990The avermectins are a family of macrocyclic lactones, produced by the soil organism Streptomyces avermitilis, which were discovered in the mid-1970's as a direct result of a screening effort for natural products with anthelmintic properties. Avermectin B1 (abamectin), the major component of the fermentation, also showed potent activity against ...
