Key Responsibilities and Required Skills for Insect Handler

🎯 Role Definition

An Insect Handler (also known as an Insectary Technician, Entomology Technician, or Insect Husbandry Specialist) maintains healthy arthropod colonies for research, product development, or production environments. This role combines hands-on animal care and laboratory best practices: rearing multiple life stages, monitoring environmental parameters, preparing diets and feeding schedules, executing breeding and genetic crosses, performing specimen collection and dissections, and maintaining meticulous records to meet quality, biosafety and regulatory standards. Ideal candidates bring practical insect husbandry experience, attention to detail, strong recordkeeping, and the ability to follow SOPs in controlled environments.

Core Responsibilities

Primary Functions

Maintain, expand and monitor multiple insect colonies (including eggs, larvae/nymphs, pupae and adults) according to standard operating procedures (SOPs), ensuring consistent life-stage distribution and stable population dynamics to meet experimental and production requirements.
Prepare and deliver species-appropriate diets and feeding regimens (e.g., artificial diets, sugar solutions, blood feeding, plant material) on scheduled cycles, document consumption, and adjust protocols to maintain colony health and productivity.
Set up and manage environmental chambers, incubators and climate-controlled rooms—establishing and continuously monitoring temperature, humidity, photoperiod and ventilation settings to match species-specific husbandry parameters and experimental designs.
Perform daily visual health assessments, mortality counts, behavioral observations and activity scoring; identify and remediate disease outbreaks, infestations, abnormal mortality trends or nutritional deficiencies in a timely manner.
Execute routine breeding programs and genetic crosses, track pedigrees and colony lineages, and manage quarantines for new or transferred strains to preserve genetic integrity and experimental reproducibility.
Collect, sort and stage specimens (eggs, larvae, pupae, adults) using sterile technique and appropriate tools (aspirators, sieves, brushes), ensuring specimens are correctly staged and labeled for assays, experiments or transfers.
Conduct specimen dissections, micro-injections, mountings or other preparatory laboratory techniques as required for downstream assays, microscopy, or molecular analysis while maintaining chain-of-custody and sample integrity.
Administer and operate specialized equipment such as aspirators, stereomicroscopes, Hemotek or membrane feeders, CO2 anesthesia systems, autoclaves and environmental sensors; perform daily calibration and basic troubleshooting.
Implement and document routine sanitation, equipment sterilization, cage and housing turnover, and waste disposal following biosafety level guidelines and institutional policies to prevent contamination and cross-colony transmission.
Maintain accurate, time-stamped electronic and/or paper laboratory records, colony logs, feeding charts and inventory lists; produce summary reports and metrics (mortality rates, fecundity, generation time) for supervisors and research staff.
Support bioassays, insecticide resistance assays, pathogen challenge experiments or behavioral trials by preparing standardized insects, administering treatments, and recording endpoints according to experimental protocols and GLP/GMP when required.
Order, receive, inspect and manage inventory of diet ingredients, rearing containers, cages, antibiotics, disinfectants and other consumables; forecast supply needs and manage stock rotation to avoid shortages or expired materials.
Adhere to institutional biosafety committee (IBC), occupational health and safety, and PPE requirements; maintain training records for personnel working in insectary spaces and coordinate required certifications.
Train and mentor new technicians, student interns and summer assistants on insect handling, SOPs, safety protocols, and accurate recordkeeping; evaluate competency and provide feedback.
Conduct routine environmental monitoring and QC checks (temperature/humidity logs, light intensity, CO2 levels, microbial swabs) and escalate deviations to management with corrective action recommendations.
Assist with field collection, trapping and identification of wild specimens for colony refreshment or research needs; coordinate permits, sample transport and quarantine procedures to ensure compliance.
Prepare experimental cohorts with precise age, sex ratios and physiological status (e.g., gravid, sugar-fed, blood-fed) and deliver them to research teams on schedule for downstream assays.
Support regulatory and animal welfare documentation by compiling colony histories, transport manifests, euthanasia records, and disposal logs in accordance with institutional and governmental standards.
Perform basic laboratory analytics and data entry (spreadsheets, LIMS) for colony performance metrics and experimental results, and help generate graphs/tables for team reports and publications.
Troubleshoot colony health problems by implementing root cause analyses (environmental, nutritional, contamination, genetic factors), testing hypotheses with small-scale trials, and reporting outcomes with recommendations for long-term mitigation.
Participate actively in cross-functional meetings with research scientists, quality assurance, facilities and purchasing to coordinate experimental timelines, facility maintenance and equipment upgrades that impact insectary operations.
Package and prepare live insects and preserved specimens for internal transfers, external collaborators or shipping—ensuring compliance with live animal transport regulations, labeling, and containment standards.
Maintain cold chain and sample handling procedures for biological materials associated with insect colonies (symbionts, pathogens, cryopreserved lines) and coordinate with central biorepositories as needed.
Implement continuous improvement initiatives to reduce rearing losses, streamline workflows and improve reproducibility across colony batches while documenting changes and evaluating impact.

Secondary Functions

Assist in laboratory inventory audits and participate in annual QA reviews to support GLP/GMP compliance.
Provide technical support for protocol development, validation, and revision; draft SOPs and contribute to training documentation.
Support ad-hoc sample processing, specimen imaging, and microscopy tasks for other laboratory groups.
Coordinate with facilities for scheduled maintenance of HVAC, environmental chambers, and emergency backup systems to prevent colony loss.
Contribute to space planning for cage racks, shelving and quarantine areas to optimize workflow and biosecurity.
Participate in safety drills, emergency response planning, and decontamination procedures for biosafety incidents affecting insectary operations.
