In vivo and in silico analyses show natural compounds like garlic may reduce rice weevil infestation and promote grain safety.

To evaluate the insecticidal effects of plant powders against the rice weevil in comparison to a model insecticide.
Tested five plant powders against the rice weevil
Conducted GC-MS analysis to identify phytocompounds
Performed in silico analysis for eco-friendly predictions
Evaluated adult mortality, progeny reduction, and weight loss.
Compared results with Malathion as a model insecticide.
Neem powder showed the highest mortality rate at 87.5%.
Clove and neem reduced progeny by 84.41% and 88.07%, respectively.
Weight loss reduction was 2.98% for neem and 9.73% for clove.
Clove exhibited the highest repellency at 64.17%.
LC50 values decreased over time, indicating increased toxicity.

Hamama et al. (2025) studied this question.
