Summary
This study developed a novel, eco-friendly termite control method using photo-immobilised silk fibroin embedded with bifenthrin. This technique offers long-term stability and high efficiency against termites at low doses.
Area of Science:
- Materials Science
- Entomology
- Environmental Science
Background:
- Termites cause significant global damage to agriculture, forestry, and structures.
- Conventional termite control methods pose environmental and health risks.
Purpose of the Study:
- To develop an environmentally benign termite control strategy.
- To combine chemical control with a photoimmobilisation technique using silk fibroin and bifenthrin.
Main Methods:
- Silk fibroin was used as a carrier to embed bifenthrin.
- Bifenthrin-silk fibroin was photoactively immobilised on wood surfaces using UV treatment.
- Characterisation involved FTIR, UV-Vis, fluorescence, CHN analysis, SEM, AFM, ESCA, and bioassays.
Main Results:
- The embedded bifenthrin showed excellent protection against free release and long-term stability.
- A slow-release mechanism with high termite control efficiency was achieved at a low dose (1.25 µg cm⁻²).
Conclusions:
- Photoimmobilisation of silk-fibroin-embedded bifenthrin offers a novel and environmentally sound approach for termite management.
- This method protects materials susceptible to termite attack through a stable, slow-release mechanism.

Biopesticides offer a sustainable alternative to chemical pesticides, utilizing microbial agents to control agricultural pests. Bacillus thuringiensis (Bt) is a widely employed bacterium known for its potent insecticidal activity. Bt biopesticides are favored for their specificity to insect pests, minimal environmental impact, and natural degradability.Mechanism of Bt Toxin Action Bt produces insecticidal crystal (Cry) proteins during its sporulation phase. These proteins form parasporal...
01:15Anthelminthic Agents
Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...
01:28Microbial Bioremediation of Pesticides
Pesticides often feature structurally complex chemical architectures, incorporating halogen groups and multiple aromatic rings. These characteristics confer high chemical stability, rendering many pesticides resistant to natural degradation processes. This resistance poses significant environmental concerns, as persistent pesticide residues can accumulate in ecosystems and affect non-target organisms.Despite the inherent stability of many pesticides, certain microorganisms possess the metabolic...
