This episode of "The Poor Proles Almanac," titled "Episode 141 #6: Honeybee Queens & the future of Breeding," centers on a concerning trend: the declining health and longevity of honeybee queens. The hosts, joined by their resident queen expert Andy, discuss the traditional life cycle of a queen, how this has drastically changed in recent decades, and explore potential contributing factors to this worrisome development.

The Traditional Queen Lifecycle: Longevity and Supersedure

Traditionally, a honeybee queen lives for 3 to 6 years before being superseded, a natural process where the hive replaces an aging or underperforming queen. During this time, multiple swarms may emerge from the hive, splitting the colony and allowing for the establishment of new hives. As queens age, they typically experience a decline in their egg-laying capacity, particularly towards the end of summer. When a queen fails, meaning she can no longer lay the proper ratio of worker bees, the worker bees will often force her out of the hive.

The Modern Queen: Shorter Lifespans and Mysterious Disappearances

However, as the hosts emphasize, the current reality for honeybee queens is a stark departure from this traditional lifecycle. Queens are now rarely surviving beyond two years, and their decline is happening throughout the year, not just in late summer. Furthermore, they are being superseded at unusual times and, in some cases, disappearing entirely without a trace.

Unraveling the Mystery: Exploring Potential Causes

The hosts grapple with this concerning phenomenon, acknowledging that there is no definitive answer to explain this widespread decline in queen health. They challenge the mainstream explanations, which often attribute these issues to aggressive bees, bad weather, and queens getting lost. They point out that these factors have always been present and do not adequately explain the sudden and dramatic shift in queen health.

Chemical Treatments: A Significant Impact on Reproductive Capacity

The hosts focus on the potential impact of chemical treatments used in beekeeping to control mites, suggesting that these chemicals may be a significant contributing factor to the decline in queen health. They cite a 2016 study that showed a dramatic decrease in drone sperm viability after exposure to chemical treatments. They also note that similar negative impacts on sperm viability have been observed in queens exposed to these chemicals.

Transportation Stress and its Impact on Sperm Viability

Beyond chemical exposure, the hosts discuss how the transportation process itself can negatively affect queen health. Queens are often shipped long distances in conditions that are either too warm or too cold, which can lead to reduced sperm viability and compromise the queen's ability to establish a healthy hive.

The Importance of Diet: Beyond Sugar Water

The hosts delve into the critical role of diet in honeybee health, emphasizing that while a diverse diet is essential, many beekeepers rely heavily on sugar water, particularly during times when natural food sources are scarce. This practice, while intended to sustain the hive, lacks the nutritional complexity of honey and pollen, potentially impacting the queen's health and longevity.

A Confluence of Factors: A Recipe for Decline

The episode highlights that the declining health of honeybee queens is likely not attributable to a single factor but rather a combination of stressors. The hosts underscore that the very practices employed to support honeybees, such as chemical treatments, long-distance transportation, and reliance on sugar water, may be inadvertently contributing to their decline.

Breeding Practices and the Quest for Healthy Queens

The hosts explore the role of breeding practices in addressing the queen health crisis. They discuss the importance of factors like genetics, the age of worker bees involved in raising new queens, and the size of the queen cells. They also mention the work of researchers like Torben Schiffer, who focuses on studying wild honeybee populations to gain insights into natural breeding patterns and the potential for improving queen health.

Local Queens and Natural Adaptation: A Path Forward

The episode concludes with a call for a more sustainable approach to beekeeping, one that prioritizes the use of local queens adapted to specific environments and minimizes the reliance on interventions that may have unintended consequences. The hosts advocate for allowing bees to adapt naturally and suggest that reducing human intervention may be key to ensuring the long-term survival of healthy honeybee populations.
