Insecticide resistance in social insects: assumptions, realities, and possibilities

Area of Science:

• Entomology
• Pest Management
• Evolutionary Biology

Background:

• Insecticide resistance is an evolved trait allowing insects to survive pesticide exposure.
• Eusocial insects, encompassing beneficial and pest species, are frequently exposed to insecticides.
• Documented cases of insecticide resistance are notably fewer in eusocial insects compared to nonsocial insects.

Purpose of the Study:

• To investigate factors that may limit the development or detection of insecticide resistance in eusocial insects.
• To review existing literature on insecticide resistance within eusocial insect groups.
• To identify knowledge gaps and propose future research directions for understanding eusocial insect resistance.

Main Methods:

• A comprehensive literature survey was conducted to gather data on documented insecticide resistance in eusocial insects.
• Analysis focused on comparing resistance prevalence across different eusocial insect taxa.
• Identification of potential ecological, genetic, and social factors influencing resistance.

Main Results:

• Insecticide resistance is well-documented in bees, a group of eusocial insects.
• Evidence for insecticide resistance is significantly sparser in other major eusocial pest groups, including ants and termites.
• The review highlights a general scarcity of resistance data for many eusocial insect species.

Conclusions:

• The limited documentation suggests factors may inhibit resistance evolution or its detection in eusocial insects.
• Future research should employ more adaptable experimental models and extensive geographic sampling.
• Investigating the roles of social structure, symbionts, genetics, and ecological context is crucial for a comprehensive understanding of eusocial insect resistance.
