Abstract
Probit analysis demonstrated a clear time-dependent increase in toxicity of all tested insecticides against Tuta absoluta. LC50 values consistently declined from 6 to 12 hours of exposure, indicating enhanced mortality with prolonged contact duration. Among the evaluated products, Belt SC 480 exhibited the lowest LC50 values, including 95% confidence limits at all exposure intervals, followed by Delta 2.5 EC and Benezer Plus 38.5% EC. Conversely, Titan 25 WDG required comparatively higher doses to achieve similar mortality levels, suggesting relatively slower toxic action. The findings demonstrate variability in efficacy profiles among tested insecticides and highlight the importance of integrating mortality and lethal time metrics when selecting products for effective T. absoluta management. These results provide practical guidance for optimizing insecticide use under glasshouse conditions and contribute to resistance management strategies within integrated pest management (IPM) programs.
The fall armyworm, Spodoptera frugiperda (J. E. Smith), is an invasive maize pest for which reliable baseline susceptibility data are required to support insecticide selection and resistance monitoring. This laboratory study compared the toxicity of five commonly used insecticides—emamectin benzoate 5 SG, chlorantranil...

Tetranychus urticae Koch (Acari: Tetranychidae) is a polyphagous pest of global agricultural importance, with a high capacity for adaptation and numerous cases of resistance to synthetic acaricides. In response to this problem, botanical products, such as neem oil, represent promising alternatives. This study evaluated...

Spodoptera littoralis is a highly destructive pest that threatens various economically important crops. This study evaluated the sublethal effects of five insecticides (Chlorantraniliprole, thiacloprid, emamectin benzoate, indoxacarb, and Bacillus thuringiensis) on the nutritional indices and growth of 3rd and 5th inst...

The pollen beetle, Brassicogethes aeneus, is a major pest of winter oilseed rape in Europe, and the development of insecticide resistance remains a key challenge for its management. This study evaluated recent changes in susceptibility of B. aeneus populations to lambda-cyhalothrin, etofenprox, acetamiprid and thiaclop...
