What visual sign indicates the presence of dead brood likely due to chilling?

• A. Brightly colored larval stages
• B. Even distribution of all brood size
• C. Brood death on the fringes with healthy brood central
• D. Absence of any brood

Answer: (C)

The presence of dead brood that is likely due to chilling can be indicated by observing brood mortality at the fringes of the brood nest, while healthy brood remains concentrated in the central area. This pattern occurs because worker bees are often unable to maintain optimal temperatures at the edges of the brood area, especially during cooler weather. As a result, the brood located at the outer edges may succumb to cold, while the brood in the warmer, more protected center survives. This scenario highlights important aspects of bee colony management. Understanding how temperature affects brood development is essential for beekeepers, particularly in terms of hive placement and management practices during cooler months. The ability to identify such signs helps in diagnosing issues quickly, allowing for timely interventions that can prevent further losses in the hive’s population.
