Title: "Fenitrothion-Deltamethrin DP: A Versatile Tool for Stored Product and Structural Pest Management"

Abstract:

The 1% fenitrothion + 0.13% deltamethrin DP formulation combines organophosphate persistence with pyrethroid knockdown power. Laboratory bioassays demonstrate 100% mortality in pyrethroid-resistant German cockroaches (Blattella germanica) within 24 hours at 2g/m² application rate. Field trials in Thai rice warehouses showed 98% control of Rhyzopertha dominica for 8 months post-treatment.

Key Advantages:

1. Resistance Management: Synergistic ratio (1:0.13) counters metabolic resistance

2. User Safety: DP formulation minimizes inhalation risks vs. aerosol applications

3. Cost Efficiency: 50% reduction in application frequency vs. single MOA products

Performance Data:

• Knockdown Time: 7-12 minutes for Periplaneta americana

• Residual Activity: 60-90 days on non-porous surfaces

• Temperature Stability: Effective from 10°C to 40°C

Regulatory Status:

• WHO Recommended: For vector control in epidemic situations

• EPA Registered: Structural pest control use

• APVMA Approved: Stored grain protection

• EU Status: Not approved (fenitrothion restrictions)

Conclusion:

This DP formulation remains particularly valuable for stored product protection in tropical climates. Future development should focus on bio-based carriers to enhance environmental profile while maintaining efficacy against resistant pest populations.
