What does this research mean for the field?

Plant-based formulations containing neem oil, garlic, or citric acid-pyroligneous extract significantly reduce oviposition and abundance of the two-spotted spider mite (Tetranychus urticae), with neem oil showing the strongest oviposition reduction and garlic exhibiting the strongest repellent effect. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To evaluate the repellent, anti-ovipositional, and population-suppression effects of neem oil, a garlic-based formulation, and a citric acid–pyroligneous extract formulation against Tetranychus urticae.

Overview

Laboratory bioassay demonstrates significant repellency and reduced oviposition in Tetranychus urticae across three natural plant extracts, highlighting their value for sustainable pest management.

Key Points

To evaluate the repellent, anti-ovipositional, and population-suppression effects of neem oil, a garlic-based formulation, and a citric acid–pyroligneous extract formulation against Tetranychus urticae.
Conducted laboratory bioassays using bean plants (Phaseolus vulgaris) as substrates treated with field-recommended concentrations of three natural product formulations.
Assessed repellency, mite abundance, and oviposition after 24 hours relative to an untreated control.
All three botanical formulations significantly reduced oviposition and mite abundance relative to the control after 24 hours.
Neem oil elicited the strongest reduction in oviposition, whereas the garlic-based formulation exhibited the greatest repellent effect.
Both the garlic-based formulation and citric acid–pyroligneous extract concurrently inhibited egg-laying, demonstrating complementary pest-management potential.
