Breeding Black Soldier Fly Larvae In-House. Top 5 Challenges and Pitfalls

by | Aug 19, 2024

Insect farming, particularly Black Soldier Fly (Hermetia Illucens) farming, is gaining traction as a sustainable protein production and waste management solution. However, managing Black Soldier Fly breeding (reproduction) and maintaining an in-house Black Soldier Fly colony present several challenges that can hinder efficiency and scalability.

This article explores the top challenges Black Soldier Fly (BSF) farmers face. It highlights the benefits of an outsourced or hybrid solution, where buying BSF neonates can mitigate many of these issues.

Challenge 1. Production Stability and Predictability

 

Breeding Consistency

Maintaining breeding consistency is crucial for the success of BSF farming. Consistency ensures larvae develop uniformly, leading to predictable yields and high-quality protein production. However, achieving this consistency takes time and effort.

Accurate Dosing and Feed Amounts

Accurate dosing and feed amounts are critical to maintaining consistency in BSF farming. Overfeeding or underfeeding can result in suboptimal growth conditions, affecting the larvae’s health and development. Monitoring and adjusting feed levels require meticulous attention and expertise, which can be challenging to maintain consistently in-house.

Neonate Quality

The quality of neonates, or newly hatched larvae, significantly impacts the overall stability of the production. In-house breeding requires precise control over breeding conditions to produce high-quality, synchronized neonates in a consistent manner. Variability in neonate quality can lead to uneven growth rates and reduced yields, complicating the farming process. Furthermore, it can also lead to a suboptimal feed conversion rate (FCR) and, subsequently, to increased feed expenses.

Challenge 2. Breeding and Egg Production

 

Fly Colony Management

Maintaining a healthy fly colony is crucial for continuous egg production. However, managing the colony can be challenging due to the specific requirements for emerging, mating and egg-laying (oviposition). Flies need optimal conditions to mate successfully, including appropriate lighting, temperature, and humidity. Any disruption in these conditions can reduce mating success and egg production.

Risk of Disease Outbreaks

Like any form of animal husbandry, insect farming is susceptible to disease outbreaks. Infections can spread rapidly in dense populations, leading to significant losses. Maintaining biosecurity in in-house BSF farming operations involves quantitative and quality control to prevent contamination and manage diseases, which can be labor-intensive and costly. In addition, BSF facilities attract other fly species that can contaminate the colony, reducing performance and may lead to safety issues.

Egg Harvesting and Handling

Another significant challenge in BSF breeding is collecting and handling eggs efficiently. Eggs are delicate and require careful handling to prevent damage. Ensuring eggs are collected, incubated, and hatched under optimal conditions is essential for producing neonates with high fitness. This process is labor-intensive and requires precise timing and techniques to maximize hatch rates and neonate quality.

Challenge 3. Genetic Drifts

 

Inbreeding Depression

A lack of genetic diversity due to repeated inbreeding within a limited population can lead to genetic drifts. This results in weakened individuals with reduced fertility, slower growth rates, and higher susceptibility to diseases.

Accumulation of Mutations

Harmful mutations can accumulate in a closed population over generations. Without introducing new genetic material, these mutations can have a cumulative negative effect on the colony’s overall health and productivity.

Adaptation to Suboptimal Conditions

A closed breeding environment can lead to the population adapting to the specific conditions of the facility, which may not be ideal for optimal growth and reproduction. This narrow adaptation can reduce the population’s ability to thrive in different environments or conditions, making the colony less adaptable to changes or stressors.

The Hybrid Breeding Model

Outsourcing part of the Black Soldier Fly (BSF) breeding process enhances genetic diversity. It mitigates the risks of inbreeding depression by introducing flies with diverse genetic backgrounds to refresh the colony. Regular genetic refreshment through outsourcing keeps the colony dynamic and adaptable, preventing stagnation and maintaining long-term viability. Leveraging specialized breeding facilities’ expertise and advanced techniques like FreezeM’s ensures optimal breeding practices and precise genetic management, resulting in a healthier, more productive, and resilient colony.

Challenge 4. Technical and Operational Complexity

 

Growth Conditions

Optimal growth conditions, including temperature, humidity, and light, are essential for efficient BSF breeding. Any deviations from the ideal conditions can dramatically affect the reproduction performance of a colony. Maintaining these conditions consistently requires advanced technology and continuous monitoring, adding to the operational complexity.

Advanced Farming Systems

Setting up and maintaining an efficient BSF farming operation requires advanced farming systems, including automated feeding and climate control systems. These technologies are essential for optimizing production but come with high initial costs and require specialized knowledge to operate and maintain.

Labor and Expertise

BSF breeding demands a skilled workforce knowledgeable in entomology and biology, as well as dedicated labs and breeding facilities. Recruiting and training staff to meet these requirements can be challenging, especially in regions where insect farming is not widely practiced. The operational complexity increases as the production scale grows, necessitating a larger and more skilled workforce.

Challenge 5. Scaling Up

The transition from small-scale to large-scale BSF breeding involves overcoming significant challenges related to equipment, environmental control, work protocols, biological behavior, and manpower. Effectively addressing these issues is crucial for the sustainable growth and success of BSF breeding facilities.

Implementing New Equipment

Implementing new equipment is often costly and requires extensive operator training. These new systems also demand numerous dry runs and meticulous calibration, a process that many companies find more challenging than initially anticipated. While reliable rearing and processing systems are available on the market and can be acquired from several suppliers, this is not the case for breeding. In this case, breeding capex is more risky and can result in a higher depreciation rate due to frequent upgrades or installments of new systems.

Stabilizing Growth Conditions

Maintaining optimal conditions for BSF growth is crucial, but in large rooms, this task becomes far from trivial. Inconsistent conditions can profoundly affect growth rates and escalating operational costs, making precise environmental control a critical component of successful scale-up.

Revising Work Protocols

Work protocols that function well on a small scale often need adaptation for larger operations. Many tasks that were previously performed manually must be automated to maintain efficiency. However, suitable automation solutions are not always readily available and may require custom development and adjustment. This transition to automation necessitates further workforce training to ensure smooth operation.

Adapting to Biological Changes

Biological factors also come into play, as insects tend to behave differently when reared in large quantities. This means biological setups effective at a small scale may need to be re-established or modified for larger-scale operations. Understanding and adapting to these behavioral changes are essential to maintaining colony health and productivity.

Advantages of Outsourced and Hybrid Breeding Models

Outsourced or hybrid breeding solutions offer significant advantages for BSF farming operations by addressing critical challenges associated with in-house breeding. One of the key benefits is the separation of breeding and rearing, which highlights the importance of the specialized knowledge and investment required for successful breeding. By outsourcing breeding or adopting a hybrid model, facilities can ensure a consistent quality and supply of neonates, which is crucial for maintaining a stable and productive process.

This approach streamlines operations and reduces the complexities and costs associated with breeding, allowing farmers to focus on growing larvae, improving productivity, and scaling their operations faster and more efficiently. By purchasing high-quality neonates from specialized suppliers, farmers can leverage the expertise and resources of professional breeding facilities, ensuring the long-term health and viability of their BSF colonies.
