Author Information
Author(s): Hoffmann Eric J., Middleton Samantha M., Wise John C.
Primary Institution: Michigan State University
Hypothesis
The study investigates the ovicidal effects of various insecticides on the plum curculio, Conotrachelus nenuphar.
Conclusion
Azinphos-methyl was found to be the most effective insecticide against plum curculio eggs, while other tested compounds showed varying levels of activity.
Supporting Evidence
- Azinphos-methyl was the most toxic compound tested against plum curculio eggs.
- Thiacloprid and clothianidin had LC50 values below 100 ppm.
- Thiamethoxam, indoxacarb, and pyriproxifen were not ovicidal at 100 ppm.
Takeaway
This study tested different insecticides to see which ones could kill the eggs of a pest called plum curculio, and found that one chemical worked best.
Methodology
An in vitro assay was developed to assess the ovicidal effects of various insecticides on plum curculio eggs.
Limitations
The study primarily focused on in vitro conditions, which may not fully replicate field conditions.
