Evolutionary psychology of entomophobia and its implications for insect conservation

Many people, especially those living in developed countries, exhibit irrational negative feelings (e.g. fear, disgust, and aversion) toward insects. This so-called 'entomophobia' has often been suggested as a key contributing factor to the ongoing global decline in insects. However, this topic has not been well-investigated. From this point of view, we discuss the formation processes of entomophobia and its consequences from an evolutionary psychological perspective. Adopting the concept of the behavioral immune system, we suggest that the negative responses toward insects exhibited by modern people are driven by a series of emotional, cognitive, and behavioral traits that evolved to avoid infectious diseases. We then provide several strategic recommendations for mitigating the prevalence of entomophobia and a roadmap for better understanding how individual-level entomophobia can influence insect conservation. Understanding the human psychological dimension behind the ongoing decline of insects will provide useful insight on how best to mitigate this decline.
