Ruijinte has completed a 12-month outdoor weathering test on sticky trap base materials and insect adhesive used in agricultural and forestry pest monitoring. The test evaluated how different material combinations perform under continuous UV exposure, seasonal rainfall, high humidity, and temperature fluctuations. The results provide practical guidance for selecting sticky traps in different climate zones.
Sticky traps are widely used in green pest control programs for monitoring flying pests such as whiteflies, thrips, aphids, leafminers, and small moths. In open-field orchards and forest plots, however, trap performance depends heavily on material durability. A trap that loses adhesion or warps after a few weeks produces unreliable data and increases replacement labor.


Test Setup and Scope
The 12-month test was conducted at an outdoor exposure site representative of subtropical agro-forestry conditions. Test samples included standard paper-based sticky boards, waterproof sticky cards, and UV-stabilized sticky trap sheets. All samples were mounted on standard field frames at typical monitoring height and exposed to natural weather conditions without artificial shading.
Evaluation criteria included:
- Adhesive retention and tackiness over time
- Base material deformation, warping, and delamination
- Color fading under UV radiation
- Physical integrity after repeated rain and humidity cycles
- Ease of insect identification on the trap surface
Samples were inspected at regular intervals, and performance was recorded under both dry and wet conditions.
Key Findings
The test produced several practical observations for field deployment.
Waterproof base materials significantly outperformed paper-based boards in humid and rainy conditions.
UV-stabilized materials retained color and adhesive longer under direct sunlight.
High temperatures affected adhesive flow, while low temperatures increased stiffness.
Rain intensity and duration were more important than total annual rainfall.
Trap replacement intervals should be climate-adjusted.
