Frequent rainfall, cloudy conditions, and high humidity during the monsoon are creating significant challenges for beekeepers across Punjab, according to experts from Punjab Agricultural University (PAU). The weather disrupts foraging, weakens bee colonies, and increases the risk of pests and diseases.
Rain-Proofing Hives Essential
Experts emphasize that the first line of defense is rain-proofing hives. Water intrusion can lead to mold, mildew, and weakened bees. Hives should be placed on iron stands, away from waterlogging-prone areas, and inclined slightly to drain rainwater. Langstroth hives made of durable kail wood with metal sheet roofing provide better insulation. Cracks and gaps must be sealed with mud to keep interiors dry.
Maintaining Internal Hive Environment
Before rainfall, colonies should be cleaned of debris and inspected for wax moth infestations. Adequate ventilation prevents moisture buildup. Placing a super chamber over the brood chamber improves airflow, and shifting combs helps reduce excess humidity.
Nutritional Challenges
Nutrition is a pressing concern as colonies rely on supplementary feeding. Ensuring honey reserves before the season is vital. Sugar syrup (equal parts sugar and water) can be offered during prolonged showers. Pollen supplements support brood rearing; a ten-frame colony requires about 250 grams of pollen fortnightly.
Gurpreet Singh Makkar, principal extension scientist (entomology) at PAU, states, "The rainy season tests every beekeeper's patience and skill." He adds that with regular inspections, dry hives, proper ventilation, and timely feeding, colonies can be kept strong and productive.
Robbing Behavior Threat
The season also heightens the threat of robbing behavior, where bees raid weaker colonies for food. Preventive measures include reducing hive entry size, feeding colonies uniformly in the evening, and uniting weak colonies using the 'Newspaper Method.' If robbing occurs, sealing cracks, covering entries with wire mesh, and shifting colonies can break scent trails. Empty combs should be fumigated with sulfur to prevent wax moth damage.
Makkar emphasizes that beekeepers need to plan better, increase vigilance, and ensure timely interventions from July to mid-September to safeguard bee colonies' health and productivity.
