Interpretive Summary:

Technical Abstract: A big group of enzymes with the capacity to break naphtyl-acetate bonds is currently being studied for their relevance in resistance to pesticides of agriculture and livestock importance. From these enzymes, the serin-estera have been identified in numerous species of insects including mosquitoes, flies, roaches, and ticks. Although the specific mode of action of these enzymes is still under study, it is believed they act through a) overexpression of the esterases and sequestering of the substrate, b) augmented metabolic detoxification. This last action is believed to be responsible in the case of the cattle tick Boophilus microplus.
