Pesticide resistance development is an example of rapid contemporary evolution that poses immense challenges for agriculture. It typically evolves due to the strong directional selection that pesticide treatments exert on herbivorous arthropods. However, recent research suggests that some species are more prone to evolve pesticide resistance than others due to their evolutionary history and standing genetic variation. Generalist species might develop pesticide resistance especially rapidly due to pre-adaptation to handle a wide array of plant allelochemicals. Moreover, research has shown that adaptation to novel host plants could lead to increased pesticide resistance. Exploring such cross-resistance between host plant range evolution and pesticide resistance development from an ecological perspective is needed to understand its causes and consequences better. Much research has, however, been devoted to the molecular mechanisms underlying pesticide resistance while both the ecological contexts that could facilitate resistance evolution and the ecological consequences of cross-resistance have been under-studied. Here, we take an eco-evolutionary approach and discuss circumstances that may facilitate cross-resistance in arthropods and the consequences cross-resistance may have for plant-arthropod interactions in both target and non-target species and species interactions. Furthermore, we suggest future research avenues and practical implications of an increased ecological understanding of pesticide resistance evolution.

Background: The main malaria vector control methods implemented in Mozambique are insecticide-treated nets (ITN's) and indoor residual spraying (IRS). These insecticide-based interventions are currently threatened by the rapidly spreading insecticide resistance in several major malaria vectors. Monitoring of insecticide resistance is necessary to inform the selection of insecticides by control programmes.

The leaching and vertical migration risks of antibiotic resistance genes (ARGs) from fertilized soil to groundwater poses a significant threat to ecological and public safety. Insect fertilizer, particularly black soldier fly organic fertilizer (BOF), renowned for its minimal antibiotic resistance, emerge as a promising alternative for sustainable agricultural fertilization. This study employs soil-column leaching experiments to evaluate the impact of BOF on the leaching behavior of ARGs.

Insects that infest postharvest commodities cause significant damage or destruction, costing billions of dollars in lost products yearly. Insecticide treatments applied as contact insecticides are effective in managing insect populations. However, recovery of the insects after exposure to these insecticides is increased if food is present, reducing the efficacy of surface treatments and leading to continued infestations.

Organophosphate (OP) compounds have been extensively employed as pesticides, insecticides and nerve agents. Stockpiles of chemical warfare agents must be destroyed as recommended by Chemical Weapon Convention (CWC). Toxicity of OP compounds to insects and mammals is due to their ability to inhibit the activity of acetylcholinesterase.

Plant hormones like salicylic acid (SA) and jasmonic acid (JA) play crucial roles in regulating defense gene expression systems. SA mainly regulates defense against biotrophic pathogens, while JA mediates defense against necrotrophic pathogens. Compounds called plant activators including probenazole, acibenzolar-s-methyl and 2,6-dichloroisonicotinic acid (INA) activate plant immune systems, providing protection against pathogens.
