Abstract
Pesticide use is prevalent with applications from the backyard gardener to large-scale agriculture and combatting pests in homes and industrial settings. Alongside the need to control unwanted pests comes the selective pressure generated by sustained pesticide use has become a concern leading to environmental contamination, pest resistance, and, thus, reduced pesticide efficacy. Despite efforts to improve the environmental impact and reduce off-target effects, chemical pesticides are relied on and control failures are costly. Though pesticide resistance mechanisms vary, one pattern that has recently emerged is symbiont-mediated detoxification within insect pests. The localization within the insect host, the identity of the symbiotic partner, and the stability of the associations across different systems vary. The diversity of insects and ecological settings linked to this phenomenon are broad. In this mini-review, we summarize the recent trend of insecticide detoxification modulated by symbiotic associations between bacteria and insects, as well as highlight the implications for pesticide development, pest management strategies, and pesticide bioremediation.
Highlights
Environmental consciousness has increased awareness of pesticide use patterns, environmental stability, and off-target effects
While insecticide biotransformation by endogenous means is well documented in insects (Panini et al, 2016; Bass and Jones, 2018), bacterial symbionts as mechanism for in insecta insecticide detoxification was not documented until the midtwentieth century
This study demonstrated degradation of six different insecticide active ingredients by an insect-associated bacterium, but the significance of this finding to the insect host and whether it conferred pesticide tolerance remained unknown
