Ovicidal and larvicidal effectiveness of insecticides applied by dipping apples on the small fruit tortrix Grapholita lobarzewskii
Pest Management Science 63 (7), 677-681
Abstract: The larvicidal and ovicidal effectiveness of twelve insecticides on Grapholita lobarzewskii Nowicki was tested by dipping apples in different concentrations of the insecticides. Emamectin was the most effective larvicidal product, with an LC₅₀ of 0.01 mg kg^-1, closely followed by spinosad, methoxyfenozide and chlorpyrifos-methyl, with LC₅₀ values between 0.2 and 0.7 mg kg^-1. Products like imidacloprid, indoxacarb, phosmet and thiacloprid gave LC₅₀ values between 1 and 2 mg kg^-1. Lastly, chlorpyrifos-ethyl and phosalone had LC₅₀ values of around 4 mg kg^-1, whereas tebufenozide and diflubenzuron had almost no larvicidal effect. Most of the products tested had low ovicidal effectiveness, and only fenoxycarb and emamectin gave LC₅₀ values worthy of note, close to 2 mg kg^-1.
