What does this research mean for the field?

Aqueous extracts of Melia azedarach, Azadirachta indica, and Ruta graveolens are highly effective botanical acaricides against the agricultural pests Brevipalpus yothersi and Tetranychus urticae, with M. azedarach demonstrating the highest toxicity. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Laboratory bioassay reveals high acaricidal activity of botanical extracts against agricultural mites, highlighting their potential for sustainable pest management.

Key Points

To evaluate the acaricidal potential and lethal toxicity of five botanical aqueous extracts against the agricultural pest mites Brevipalpus yothersi and Tetranychus urticae.
Conducted controlled laboratory bioassays testing aqueous extracts from Azadirachta indica, Melia azedarach, Ruta graveolens, Dysphania ambrosioides, and Trichilia pallida.
Evaluated mite mortality, survival dynamics, and calculated lethal concentrations (LC50 and LC90) relative to untreated controls.
All five botanical extracts significantly reduced survival rates in both Brevipalpus yothersi and Tetranychus urticae compared with untreated controls.
Extracts of Melia azedarach, Azadirachta indica leaves, and Ruta graveolens demonstrated the strongest acaricidal activity and fastest mortality rates across evaluation intervals.
Melia azedarach demonstrated the highest overall toxicity toward both mite species, yielding the lowest LC50 values in dose–response analyses.
