Oxidative stress delays development and alters gene expression in the agricultural pest moth, Helicoverpa armigera.

ABSTRACT: Stress is a widespread phenomenon that all organisms must endure. Common in nature is oxidative stress, which can interrupt cell homeostasis to cause cell damage and may be derived from respiration or from environmental exposure through diet. As a result of the routine exposure from respiration, many organisms can mitigate the effects of oxidative stress, but less is known about responses to oxidative stress from other sources. Helicoverpa armigera is a major agricultural pest moth that causes significant damage to crops worldwide. Here, we examined the effects of oxidative stress on H. armigera by chronically exposing individuals to paraquat-a free radical producer-and measuring changes in development (weight, developmental rate, lifespan), and gene expression. We found that
