Core Responsibilities

Primary Functions

Maintain, monitor, and expand multiple insect colonies (including mosquitoes, flies, aphids, beetles, or other target arthropods) using species-specific rearing protocols to ensure healthy, contamination-free populations for research or production.
Prepare and condition rearing environments (insectaries, incubators, environmental chambers) by setting and validating temperature, humidity, light cycles, substrate, and feeding regimens to meet experimental and husbandry specifications.
Perform daily husbandry tasks such as feeding, egg collection, larval and pupal sorting, emergence monitoring, mating cages setup, and transfer of life stages while maintaining sterile technique to prevent cross-contamination.
Conduct specimen collection, identification, and morphological sorting using stereomicroscopes and keys, and prepare voucher specimens, pinned collections, or slide mounts following institutional curation standards.
Execute behavioral and physiological assays (e.g., feeding assays, choice tests, oviposition assays, flight activity assays) according to written protocols, ensuring reproducible setup, controls, and sample randomization.
Prepare tissue samples for downstream analyses including DNA/RNA extraction, PCR set-up, qPCR sample prep, and basic molecular workflow steps while maintaining contamination control and chain-of-custody documentation.
Dissect insect tissues (midgut, salivary glands, reproductive organs) and prepare microscopic slides for histology, imaging, or downstream molecular work while following documented SOPs and biosafety precautions.
Accurately record experimental conditions, colony census, mortality rates, feeding schedules, treatment applications, and assay results in electronic lab notebooks (ELNs), LIMS, or designated spreadsheets to support reproducibility and traceability.
Operate and maintain standard laboratory equipment — autoclaves, biological safety cabinets, centrifuges, microscopes, microplate readers, environmental chambers — performing routine calibration checks and documenting maintenance.
Implement and follow institutional biosafety, pest containment, and biosecurity protocols including waste segregation, sterilization of infectious material, PPE use, and proper disposal of insect and biological waste.
Prepare reagents, culture media, and specialized diets (liquid blood meals, sucrose solutions, agar substrates) used in rearing and assays, verifying concentrations, sterility, and expiration dates.
Apply insect marking, tagging, or molecular barcoding methods for cohort tracking, pedigree maintenance, or experimental identification and maintain associated metadata and tracking logs.
Assist with experimental design logistics by preparing experimental cages, arenas, chemical exposures, pesticide treatment dilutions, and control groups, and help troubleshoot setup issues to ensure valid experimental contrasts.
Perform sample labeling, aliquoting, cold-chain management, and archival storage of samples (frozen tissue, ethanol-preserved specimens, dry specimens) in compliance with lab SOPs and long-term storage requirements.
Monitor colony health through routine screening for pathogens or insect-specific contaminants and coordinate screening assays (microscopy, PCR-based pathogen detection) with senior staff or collaborators when issues arise.
Train and mentor junior technicians, interns, and student workers on insect handling, rearing protocols, proper PPE usage, and data entry standards ensuring consistent application of SOPs across personnel.
Maintain inventory of consumables, reagents, cages, and insectary supplies; prepare purchase requests, receive shipments, check certificates of analysis, and ensure stock rotation to minimize expired items.
Support regulatory and permitting processes by preparing documentation for animal care committees, biosafety committees, import/export permits, and institutional approvals including detailed colony descriptions and containment plans.
Contribute to experimental data analysis and visualization by exporting assay results, generating summary tables and charts, and providing clear notes to research staff to support manuscripts, reports, and presentations.
Draft and update standard operating procedures (SOPs), colony care manuals, and troubleshooting guides; recommend process improvements that increase colony stability, reduce mortality, or improve experimental throughput.
Coordinate with field teams to receive and process field-collected arthropod samples, perform species confirmation, and integrate field sample metadata into lab databases for downstream analysis.
Ensure quality control by running internal controls, blanks, and replicates as required for molecular assays, microscopy counts, and behavioral assays, documenting deviations and corrective actions when protocols fail to meet acceptance criteria.

Secondary Functions

Provide backup support for lab administrative duties including scheduling equipment use, managing shared calendar reservations, and coordinating facility access for visitors and collaborators.
Assist in grant proposal preparation by compiling colony histories, SOP summaries, resource needs, and preliminary data summaries for inclusion in methods and resource sections.
Participate in outreach and training activities, offering demonstrations for students, stakeholders, or partner organizations to communicate lab capabilities and safe insect handling practices.
Support ad-hoc sample requests and collaborate with collaborators to prioritize urgent experiments, ensuring clear communication of timelines and resource constraints.
Help maintain digital records, including LIMS entries, inventory databases, and compliance documentation, to support audits and institutional reporting.
Contribute to lab safety culture by participating in safety inspections, incident investigations, and by recommending improvements to containment and PPE practices.
Engage in periodic quality assurance projects such as cross-validation of colony counts, inter-technician proficiency testing, and process validation exercises.
Participate in team meetings to discuss experimental timelines, colony health status, supply forecasts, and to provide input on operational bottlenecks and capacity planning.
