Core Responsibilities

Primary Functions

Design and implement breeding programs and selection protocols to maintain genetic diversity, desired phenotypes and production stability across laboratory and production colonies.
Maintain, monitor and expand multiple insect colonies (eggs, larvae/nymphs, pupae and adults) using species-specific husbandry techniques, feeding regimes and environmental controls to meet weekly and monthly production targets.
Develop and follow detailed Standard Operating Procedures (SOPs) for all rearing operations, including feeding, mating, egg collection, incubation, pupal sorting and adult emergence to ensure reproducibility and regulatory compliance.
Conduct daily inspections of rearing racks, cages, trays and environmental chambers to identify and correct issues with humidity, temperature, light cycles and ventilation that affect survival, development time and fecundity.
Accurately count, stage and document eggs/offspring, record developmental milestones and maintain production logs and electronic colony databases for traceability, metrics and audit readiness.
Prepare and quality control artificial diets, media and other feed formulations, adjusting recipes and processing methods to optimize growth rates, survival and target trait expression.
Implement and manage mass-rearing workflows and production schedules to scale output while safeguarding colony health, including staging operations, throughput balancing and bottleneck elimination.
Screen and select breeding stock by phenotype and performance metrics (e.g., fecundity, mating success, development time, pathogen resistance) and execute controlled crosses to improve line performance.
Apply sterile insect technique (SIT) or other sterilization protocols when required, coordinating irradiation or sterilization steps safely and validating sterility/fitness trade-offs in treated insects.
Perform health surveillance, diagnostic sampling and necropsies as needed, coordinate microbial or parasitic screening with laboratory partners and take appropriate quarantine or remediation actions.
Train, supervise and coach insectary technicians, interns and seasonal staff on safe handling, accurate record-keeping and protocol adherence to grow team capability and preserve colony integrity.
Maintain and calibrate critical equipment (environmental chambers, climate control systems, sieves, sorting machines, microscopes and scales), schedule preventative maintenance and coordinate repairs to minimize downtime.
Manage inventory of consumables, substrates, rearing containers, media ingredients and PPE, place orders to avoid stockouts and validate incoming materials against quality specifications.
Coordinate shipments and transfers of insects between facilities or to external partners, handling permits, packaging, cold chain or containment requirements and tracking chain of custody documentation.
Implement biosecurity and containment protocols, including access controls, decontamination procedures, insect-proofing measures and waste disposal plans to prevent escapes and cross-contamination.
Participate in experimental design and data collection for strain improvement, performance trials or behavioral assays, linking breeding outcomes to measurable production KPIs.
Maintain compliance with institutional animal care, permit and regulatory requirements (local, state and federal) and prepare documentation for inspections, approvals and grant reporting.
Troubleshoot production problems using root-cause analysis, propose corrective actions (process, diet, environment or genetics) and verify effectiveness through follow-up monitoring.
Lead or contribute to continuous improvement projects to increase survival, reduce costs per insect, shorten generation time or automate repetitive tasks while preserving quality standards.
Collaborate with R&D, QA, regulatory, and supply chain teams to translate customer requirements and research findings into operational adjustments and breeding objectives.
Ensure meticulous data entry into laboratory information management systems (LIMS), colony management software or spreadsheets, and produce regular production and health reports for leadership and stakeholders.
Uphold safety culture by following chemical handling, biological safety and radiation safety protocols (if working with irradiators), maintaining incident logs and participating in safety training.

Secondary Functions

Support ad-hoc experimental needs from R&D such as providing age‑synchronized cohorts, special diets or genetically defined lines for behavioral or molecular studies.
Contribute to SOP development and revision, training modules and onboarding materials to standardize practices across multi-site operations.
Assist with quality assurance activities including internal audits, corrective action plans, and documentation of deviations or non-conformances.
Participate in cross-functional project teams to scale production, validate new equipment or adapt processes for commercialization.
Provide technical input to permit applications, risk assessments and standard operating procedures required by regulatory authorities and institutional biosafety committees.
Help coordinate field release logistics and post-release monitoring when the program has a field deployment component.
Support customer and partner inquiries about colony availability, specification sheets and best‑practice transport conditions for live insects.
Attend industry conferences, workshops and training to keep abreast of best practices in insect rearing, mass production and breeding methodologies.
