This study examined the larvicidal effect of trunk-injected abamectin and emamectin benzoate against walnut husk fly (Rhagoletis completa Cresson, 1929). Walnut trees in two locations years were injected with pesticides at different concentrations. For toxicokinetic studies, active ingredient content was measured leaves, flowers, husks, kernels, using a UHPLC-MS/MS analytical method. The infest...

Selamectin, a novel avermectin compound, is reviewed and discussed for its efficacy against naturally occurring infestations and infections of Ctenocephalides felis, Otodectes cynotis, and Dirofilaria immitis in ferrets; different flea species, Psoroptes cuniculi, Cheyletiella spp, and Leporacarus gibbus in rabbits; different chewing lice, Trixacarus caviae, and Chirodiscoides caviae in guinea ...

Type I modular polyketide synthases are responsible for potent therapeutic compounds that include avermectin (antihelinthic), rapamycin (immunosuppressant), pikromycin (antibiotic), and erythromycin (antibiotic). However, compound access and biosynthetic manipulation are often complicated by properties of native production organisms, prompting an approach (termed heterologous biosynthesis) illu...
