Why Must A Screened Wooden Frame Be Installed Above A Sticky Board? Boost Accuracy And Protect Your Colony

A screened wooden frame acts as a critical selective barrier within the hive. It is installed to physically separate the bee colony from the monitoring equipment below. This specific structure allows tiny debris and parasites, such as Varroa mites, to pass through its mesh while preventing honeybees from entering the area containing the sticky board.

The screen serves a dual purpose: it protects the colony from injury caused by the adhesive and prevents bees from removing fallen mites, ensuring your mortality data remains accurate and unaltered.

The Mechanics of Selective Filtration

Function of Pore Size

The screen is defined by a specific pore size. This mesh is engineered to be large enough for mites to fall through freely, but small enough to block the passage of a worker bee.

Separating Populations

By installing this frame, you create a distinct zone for monitoring that is inaccessible to the colony. This separation allows the natural "mite drop" to occur without the bees interacting with the collection surface.

Protecting Data Integrity

Preventing Hygienic Behavior

Honeybees are naturally hygienic and will actively clean debris from their hive. Without the screened frame, bees would access the sticky board to clear away fallen mites.

Ensuring Statistical Accuracy

If bees remove mites from the board, your count will be artificially low. The screen preserves the authenticity of mortality statistics by ensuring that once a mite falls, it remains on the board for you to count.

Ensuring Colony Safety

The Hazard of Sticky Boards

Sticky boards rely on strong adhesive substances to trap mites. If exposed directly to this adhesive, bees can become stuck, leading to injury or death.

The Physical Guard

The screened wooden frame acts as a shield. It prevents bees from accidental contact with the sticky surface, allowing you to monitor parasite loads without risking the health of your workforce.

Common Pitfalls to Avoid

Incorrect Mesh Sizing

If the screen's pore size is too small, mites may get caught in the mesh rather than falling to the board, skewing your data. Conversely, if the mesh is too large or damaged, bees may squeeze through and get trapped in the glue.

Improper Installation

The frame must be seated securely to ensure there are no gaps around the edges. Even a small gap can allow bees to bypass the screen and enter the monitoring chamber.

Making the Right Choice for Your Goal

When setting up your hive monitoring system, ensure your equipment aligns with your specific objectives:

If your primary focus is Data Accuracy: Ensure the screen is intact and covers the entire area of the sticky board to prevent bees from altering the mite count.
If your primary focus is Colony Health: Verify that the screen is positioned securely above the adhesive to eliminate any risk of bees coming into contact with the glue.

The screened frame is the linchpin of effective monitoring, balancing the safety of your bees with the reliability of your data.
