The use of insecticides is one of the main tools employed against pathogen vectors by governmental campaigns, private companies, and households. The intense use of these chemicals, however, has been selecting resistant populations of several arthropod species all around the world. Insecticide resistance is now claimed to be one of the main threats to the control of arthropod vectors of pathogens, especially mosquitoes.

Although new strategies of vector control are currently being tested under bad conditions, the use of insecticides will retain an important role in the near future at least. In this sense, the knowledge of processes leading to resistance is crucial to try to revert the resistant status of natural populations, avoiding resistance to new compounds, and maintaining this strategy as an effective alternative for arthropod control.

The purpose of this Special Issue is to contribute to the publication of high-quality research papers and reviews addressing recent advances in insecticide resistance in vectors of disease pathogens.

Potential topics include but are not limited to the following:

• Monitoring of insecticide susceptibility/resistance status in the field
• Understanding mechanisms selected for insecticide resistance
• Laboratory selection pressure for insecticide resistance studies
• Testing of new insecticides
• Alternative tools for evaluating insecticide resistance
• Description of national or interregional network programs for insecticide resistance monitoring or advice
