Details of Plastic tray for harp

Plastic tray that completes the electric anti-velutina harp system. Placed under the harp structure, filled with water, it retains the electrocuted velutinas that fall after touching the harp wires. Without the tray, stunned velutinas can recover on the ground, be eaten by ants or birds, or take off again — the water tray guarantees definitive death and allows counting captures to evaluate the real enemy pressure in the apiary.

💧 Why water and not a dry tray

An electrocuted velutina falls to the ground stunned but not always dead — the harp voltage knocks her unconscious for a few minutes, but if she's in the shade and cools down, she may recover and fly off. A dry tray does not solve this; the water tray does: surface tension of water + body weight + impossibility of beating wet wings means guaranteed death in a few minutes. Plus water prevents ants and birds from removing bodies before you can count the capture.

🔧 Exact fit with the Tartago harp

The tray is dimensioned to fit exactly under the Tartago harp (the anti-velutina harp in the catalogue). No side gaps where struggling velutinas could escape, no separations that let prey through to the ground. The complete system is: harp + electrical module (solar or battery) + water tray — the three components work together. The tray is emptied every 1-2 weeks during the velutina peak (July-October in affected areas) — the right moment to count and log captures.

📊 Also useful to measure real pressure

Keeping a weekly log of how many velutinas each harp catches is the most reliable way to know if pressure is rising, falling or steady in your area. With a dry tray, counting is impossible (bodies disappear). With the water tray, bodies stay countable when you empty it. For professional beekeepers or cooperatives making decisions (moving hives, installing more harps, alerting neighbours), real data beats any visual estimate.
