Pear, Insect Control with Abamectin, 1986

Insecticide and Acaricide Tests, 1987
Abstract 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.

Toxicity of Abamectin to Cockroaches (Dictyoptera: Blattellidae, Blattidae)

Journal of Economic Entomology, 1991
Abamectin 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, 1992
The 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.

Poisoning of calves reared with cows treated with abamectin

Toxicon, 2021
The aim of the present study was to describe an outbreak of poisoning by abamectin in calves less than four months of age whose mothers were treated with a pour-on product containing this ingredient. The diagnosis was based on the history, clinical signs, absence of macroscopic and histopathological findings (characteristic of this type of poisoning ...

Photodegradation of the Acaricide Abamectin: A Kinetic Study

Journal of Agricultural and Food Chemistry, 2008
The acaricide abamectin is a mixture of two colorless homologues in a molar ratio of at least 4:1 with the same structure of macrocyclic lactone. The kinetics of its degradation under direct (254 nm) and dye-sensitized (>400 nm) photoirradiation in methanol solution has been studied by UV-vis spectrophotometry, potentiometric detection of dissolved ...

Use of Abamectin in Cattle

1989
This chapter presents a summary of the efficacy data that form the basis for the clinical use of abamectin (avermectin B1) in cattle. The product is formulated in the same vehicle as used for IVOMEC (ivermectin) Injection. At the present time, AVOMEC (abamectin) Injection is registered only in Australia.

Efficacy of abamectin injection againstDermatobia hominis in cattle

Parasitology Research, 1993
The 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 ...

Ivermectin and Abamectin

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.

Abamectin Use in Crop Protection

1989
Initial indications that the avermectins possessed activity against arthropods were obtained in studies with avermectin B1a against the confused flour beetle (Tribolium confusum) and the sheep blowfly larva (Lucilia cuprina). Evaluation of the 8 major natural avermectins and several hundred semisynthetic avermectin analogs and derivatives showed that ...

Effects of abamectin on bullfrog tadpoles: insights on cytotoxicity

Environmental Science and Pollution Research, 2017
Abamectin 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.
