Mealworm Farming Guide: Prevention and Treatment of 3 Common Diseases


Yellow mealworms Farming are robust creatures that generally thrive under normal breeding and management conditions. However, as the density of your mealworm colony increases, so does the risk of disease outbreaks. This comprehensive guide aims to equip you with detailed knowledge about preventing and managing common diseases in yellow mealworms.

Mealworm Farming:Section 1: Soft Rot Disease

Soft Rot Disease--Mealworms
Soft Rot Disease–Mealworms

Symptoms: Soft rot disease manifests in mealworms as sluggishness, reduced appetite, diminished reproductive capacity, and a gradual softening and darkening of their bodies. Their excreta becomes watery and dark. Left untreated, it can lead to mass mortality.

Causes: Soft rot disease is more prevalent during the rainy season due to higher humidity, fecal contamination, feed spoilage, high breeding density, and excessive force during larval cleaning and sorting, causing injuries to mealworms.

Prevention and Treatment:

  1. Promptly identify soft-bodied mealworms by closely inspecting your colony.
  2. Provide fresh vegetables and remove any leftover food.
  3. Clean the breeding area to eliminate diseased excreta.
  4. Adjust indoor humidity levels to mitigate moisture-related issues.
  5. Administer treatment by mixing 0.25 grams of chloramphenicol or terramycin with 250 grams of bean or cornmeal per box.
  6. Transition to feeding bran mixed with fresh greens once the situation improves.

Mealworm Farming:Section 2: Drying Disease

Symptoms: Drying disease is characterized by the gradual dehydration and death of mealworms, starting from their tail and head.

Causes: Factors contributing to drying disease include high temperatures, excessively dry air, overly dry feed, and inadequate green feed.

Prevention and Treatment:

  1. Place feed boxes in cooler, well-ventilated areas to reduce the impact of high temperatures.
  2. Regularly replenish various vitamins and green feed to ensure proper nutrition.
  3. Sprinkle water on the ground to increase humidity and cool the environment.

Mealworm Farming:Section 3: Mite Infestations

Symptoms: Mite infestations result in weakened mealworms with slow growth, delayed development, reduced hatching rates, and decreased reproductive capacity.

Causes: Mites are more prevalent from July to September due to high humidity in feed, elevated temperatures, and contaminated food sources.

Prevention and Treatment:

  1. Regulate indoor air humidity to reduce mite-friendly conditions.
  2. Ensure good airflow in the breeding area, especially during the summer months.
  3. Prevent food from becoming a source of mites by keeping it clean and uncontaminated.
  4. Store feed in sealed containers to prevent mite infestations.
  5. Disinfect materials such as rice bran, wheat bran, mixed coarse grains, and coarse corn.
  6. Apply a 40% three-oxygen mite killer at a 1000 times dilution to spray corners, breeding boxes, and feed.

By meticulously following these prevention and treatment steps, you can maintain a healthy and productive yellow mealworm colony, even as the breeding density increases. Regular monitoring and swift action are vital to sustaining a thriving mealworm population.
