Abstract: The effective control of insect pests is based on the use of insecticides. Most of
these compounds act on molecular targets in the insect nervous system. However, the largescale
deployment of insecticide treatment has led to the development of resistance, which
decreases insecticide efficacy. Although the resistance mechanisms are largely studied today,
this review aims to point out new insights on the less-known cellular and molecular
factors involved in the modulation of the sensitivity of the targets to insecticides. This review
will focus on the phosphorylation/dephosphorylation process, the post-transcriptional
events such as editing and alternative splicing and the influence of the association with auxiliary
proteins of the receptors and/or ion channels targeted by insecticides. In addition, the
involvement of calcium-dependent signaling pathways in the modulation of the sensitivity
of the target to insecticides will also be considered and discussed. Finally, this review will
insist on different strategies proposed to optimize the efficacy of insecticide treatment
while reducing doses to decrease side effects on environment and on non-target organisms
by combining two different chemical insecticides or a given active ingredient associated
with biological and/or chemical synergistic agents. This review is part of the special issue
"Insecticide Mode of Action: From Insect to Mammalian Toxicity".
