Hypothesis
How do sublethal doses of spinetoram affect the biological traits and detoxifying enzymes of Tuta absoluta?
Conclusion
Spinetoram negatively impacts Tuta absoluta by reducing survival, developmental potential, and enzyme activity.
Supporting Evidence
- Spinetoram reduced the survival and developmental potential of Tuta absoluta.
- Sublethal doses prolonged the larval and pupal stages.
- Spinetoram decreased the pupation and eclosion rates significantly.
- Fecundity and egg-hatching rates were negatively affected by spinetoram.
- Detoxifying enzyme activities were inhibited by spinetoram exposure.
Takeaway
Spinetoram, a new insecticide, can harm tomato pests by making them grow slower and have fewer babies.
Methodology
Laboratory bioassays were conducted to evaluate the effects of spinetoram on Tuta absoluta larvae using leaf-dipping methods.
Limitations
The study was conducted under controlled laboratory conditions, which may not fully represent field conditions.
Participant Demographics
Third-instar larvae of Tuta absoluta collected from Jiuquan City, China.
