Phthorimaea absoluta (Meyrick) (Lepidoptera: Gelechiidae) poses a significant challenge in tomato cultivation owing to its increasing resistance various insecticide classes. This study aimed characterize the of field-collected P. population abamectin, focusing on genetic aspects and cross-resistance with other chemical groups, monitoring frequency populations. Significant variability abamectin susceptibility was observed across populations, ratios ranging from 2.6- (Juazeiro) 538-fold (Gravatá). Selective pressure Gravatá led 50-fold increase over 16 generations (h2 = 0.186). Abamectin exhibited incomplete recessiveness, female bias polyfactorial inheritance involving at least seven genes. Field populations showed ≤56% (homozygous) diagnostic concentration 5 mg L-1, although control failure not imminent. Cross-resistance emamectin benzoate milbemectin were 1 893 000- 4506-fold, respectively, indicating shared mechanism. Brazilian is notably high, yet few are nearing failure. The pattern, characterized by maternal linkage, underscores complexity managing resistance. Additionally, broad spectrum insecticides suggests diverse mechanisms play, emphasizing need for tailored management strategies within this class. © 2025 Society Chemical Industry.

Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), Tomato Leaf Miner (TLM) moth, is one of the notorious oligophagous pests solanaceous crops that mines primarily on mesophyll leaves as well bore tomato fruits. In Nepal, T. absoluta, pest has a potential to create loss up 100%, was detected in 2016 commercial farm at Kathmandu. So, farmers and researchers must heed for effective management contrivance improve yield Nepal. The devastating nature causes its unusual proliferation so it needs dire study host range, damage sustainable strategies. We discussed data information available several research papers comprehensively provided succinct occurrence world, biology, life cycle, plants, due novel control tactics which helps farmers, researchers, policy makers sustainably rise production Nepal global context attain food security. Sustainable strategies such Integrated Pests Management (IPM) approaches incorporating prioritizing biological methods with usage chemical pesticides less toxic active ingredient can be encouraged controlling sustainably.
