AI Article Synopsis
- Herbicides like atrazine and nicosulfuron can negatively influence the reproductive capabilities of the predator Podisus nigrispinus, leading to fewer mature oocytes in females.
- Despite these reproductive impacts, the overall longevity and mortality of P. nigrispinus are not significantly affected, suggesting that these herbicides are selective.
- The study highlights that while P. nigrispinus may survive exposure to herbicides, sublethal effects on reproduction could potentially reduce their population in natural environments.
Article Abstract
Herbicides can impact non-target metabolic pathways in natural enemies and lead to the reduction of these populations in the field. Behavioral characteristics, morphology and histology of reproductive structures and reproduction of females of Podisus nigrispinus (Dallas) (Hemiptera: Pentatomidae) were evaluated under the effect of the herbicides atrazine, nicosulfuron and the mixture of both. The number of mature oocytes per ovary was lower in females exposed to the herbicides atrazine, nicosulfuron and the mixture of both. Herbicides did not affect the longevity and mortality of P. nigrispinus, therefore, they are selective for this predator. On the other hand, herbicides can cause sublethal effects by affecting the reproduction of predators.
