Key Responsibilities and Required Skills for Insect Pathologist

🎯 Role Definition

An Insect Pathologist conducts laboratory and field research on diseases of insects and insect vectors, develops and evaluates biological control agents, investigates pathogen–host interactions, and translates findings into pest management strategies and publications. This role integrates entomology, microbiology, molecular diagnostics, and applied ecology to study insect pathogens (fungi, bacteria, viruses, microsporidia, nematodes) and their use or impact in agricultural, public health, and environmental contexts. Ideal candidates bring hands-on skills in insect colony maintenance, bioassays, molecular methods (PCR, qPCR, NGS), microscopy, and statistical analysis, plus experience designing field trials and securing peer-reviewed funding.

Core Responsibilities

Primary Functions

Design, lead, and execute laboratory and field research projects on insect pathogens and insect–microbe interactions, delivering clear experimental plans, milestones, and interpretable results for publications and stakeholders.
Maintain, rear, and manage laboratory colonies of target insect species under controlled environmental conditions, ensuring genetic integrity, health monitoring, and reproducible life-history data for experiments.
Isolate, culture, and identify entomopathogenic fungi, bacteria, viruses, microsporidia, and nematodes using sterile technique and appropriate microbiological methods; characterize pathogenicity and host range.
Develop and perform standardized bioassays (topical, ingestion, injection, contact, soil exposure) to quantify pathogen virulence, dose–response relationships, and sublethal effects on insect physiology and behavior.
Apply molecular diagnostics (PCR, qPCR, RT-qPCR) and Next-Generation Sequencing (NGS) workflows to detect, quantify, and genotype insect pathogens and associated microbiomes, including library prep, QC, and interpretation of sequence data.
Conduct microscopy-based analyses (light microscopy, fluorescence, confocal, SEM where applicable) to document pathogen invasion, tissue tropism, and developmental stages within insect hosts.
Design, implement, and statistically analyze laboratory and field trials evaluating biocontrol agents, entomopathogen persistence, and integrated pest management (IPM) solutions; use R or other statistical packages to model results.
Establish, monitor, and document biosafety and biosecurity practices (BSL-1/BSL-2 as required), maintain compliance with institutional biosafety committees, and ensure safe handling, disposal, and shipping of infectious materials.
Lead field evaluations of candidate biocontrol agents and pathogen transmission in agricultural and urban environments, including experimental plot layout, replication, environmental monitoring, and data collection protocols.
Contribute to development, optimization, and validation of in vitro and in vivo assays for pathogen efficacy, insect susceptibility, and resistance monitoring, including assay standard operating procedures (SOPs).
Integrate ecological and epidemiological approaches to study vector competence, transmission dynamics, seasonal abundance, and environmental drivers of insect disease outbreaks.
Collaborate cross-functionally with entomologists, microbiologists, molecular biologists, ecologists, and statisticians to translate basic research into deployable pest management products and recommendations.
Author and co-author scientific manuscripts, peer-reviewed publications, technical reports, and extension/outreach materials; present findings at scientific conferences, stakeholder meetings, and industry forums.
Write and manage grant proposals, research contracts, and project budgets; secure funding from federal agencies, foundations, and industry partners and administer awarded grants.
Train, supervise, and mentor graduate students, postdocs, and laboratory personnel in insect-rearing techniques, bioassay methods, molecular workflows, data management, and safety protocols.
Develop and maintain laboratory quality systems, data management practices (LIMS or equivalent), and reproducible experimental records to support regulatory submission or product development.
Perform insecticide and biopesticide resistance testing and monitoring using established protocols; analyze trends and advise on resistance management strategies.
Assist with product development activities for commercial biocontrol agents: formulation testing, shelf-life studies, dose optimization, and regulatory dossier preparation.
Engage with regulatory agencies (EPA, USDA, state departments) to support registration, environmental risk assessment, and compliance for microbial pesticides and biological agents.
Conduct risk assessment studies to evaluate non-target effects, environmental persistence, and compatibility of entomopathogens with beneficial insects, pollinators, and ecosystem services.
Implement and maintain partnerships with external stakeholders (growers, extension services, public health agencies, industry partners) to translate research into on-the-ground integrated pest management practices.
Monitor literature and emerging technologies in insect pathology, genomics, and microbial control; recommend and implement new methods (e.g., metagenomics, CRISPR diagnostics) to advance program objectives.

Secondary Functions

Provide technical support for diagnostic services and rapid-response outbreak investigations; triage samples, run diagnostics, and prepare actionable reports for decision makers.
Support institutional outreach and extension programs by developing training materials, delivering workshops, and producing extension publications on insect diseases and biocontrol strategies.
Contribute to institutional committees (biosafety, animal care where relevant) and assist with protocol review and compliance documentation.
Assist commercialization teams by transferring laboratory assays to pilot-scale production, conducting GLP-compatible studies, and supporting technology transfer activities.
Participate in cross-disciplinary grant collaborations and consortiums to broaden research impact and secure multi-institutional funding.
Support ad-hoc environmental monitoring and surveillance efforts for invasive pests and emergent pathogens in collaboration with regulatory or public health agencies.
