What is a common sign of Tropilaelaps clareae infestation in a bee colony?

A common sign of Tropilaelaps clareae infestation in a bee colony is deformed brood. This parasitic mite specifically targets honeybee brood and can cause significant developmental issues. The presence of deformed brood is indicative of the mites feeding on the developing larvae, which leads to physical deformities and ultimately results in the death of the affected bee larvae. These deformations may include twisted bodies, discolored pupae, and abnormal wings.

In contrast, regular brood development, increased honey yield, and strong brood rearing would generally indicate a healthy bee colony without signs of severe infestation. Observing deformities in brood is a critical part of monitoring for pests and diseases in bee colonies, making it essential for beekeepers to be vigilant about such signs.
