Insecticide resistance in Tuta absoluta: integrating dose–response assays analysis, diagnostic concentrations, and resistance management strategies

Insecticide Resistance in Indian Vegetable Ecosystems: A Critical Appraisal of Toxicological Mechanisms, Resistance Frequencies and Control Options

Vegetable production in India depends heavily on repeated insecticide application, and the arthropod species that dominate these systems have responded with rapid and repeated adaptation. The result is a control problem that is simultaneously toxicological, ecological and institutional, yet the literature describing it...

Induced Resistance Against Tuta absoluta in Tomato Cultivars Using Eco-friendly Plant Growth Regulators in Egypt

The South American tomato pinworm, Tuta absoluta, represents a severe threat to tomato production in Egypt, capable of causing up to 100% yield loss and devastating economic damage, a challenge intensified by climate change and escalating insecticide resistance. This study aimed to evaluate the efficacy of eco-friendly...

Comparative Toxicity and Lethal Time Analysis of selected Insecticides against Tuta absoluta under Glasshouse Conditions

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...

Insecticide Resistance Management for Mosquito Control: Mechanisms, Evidence, and Future Challenges.

Validation of a novel bioassay method for the evaluation of the activity of slow-acting insecticides on tomato borer Phthorimaea absoluta.

BACKGROUND Phthorimaea absoluta is one of the most devastating pests of tomato crops worldwide, with its control relying heavily on chemical insecticides. Assessing the risk of control failure and resistance levels is critical for evaluating insecticide efficacy. The globally adopted bioassay protocol is Insecticide Re...

Metabolic resistance drives cross-resistance in Aedes albopictus to pyriproxyfen and pyrethroid insecticides

It is demonstrated that metabolic resistance mediates cross-resistance between pyriproxyfen and pyrethroids in Ae.
