The Division of Entomology and Plant Pathology within the Department of Natural Resources is directed, by statute, to seek the control of any "pest or pathogen" that may harm nursery stock, crops, other vegetation, or bees. In addition, the Division of Entomology and Plant Pathology has regulatory authority to develop measures for the protection of bees and the honey industry.

"Pest or pathogen" is broadly defined in the law to list several life forms, including arthropods, nematodes, microorganisms, and mollusks. "Arthropods" include insects (examples: beetles and flies), arachnids (examples: spiders and ticks), crustaceans (example: crayfish), and myriapods (example: centipedes).

Division of Entomology and Plant Pathology

Responsibilities for the regulation of arthropods and other pests or pathogens, and for the protection of bees, are assigned by the Indiana General Assembly in statutes and implemented largely through rules. The Natural Resources Commission adopts permanent rules, and they have the force and effect of law.

Permanent Rules

  • 312 IAC 18-2 Sets general standards for determining areas infested with pests or pathogens and for establishing quarantines.
  • 312 IAC 18-3 Describes quarantines applicable to particular organisms (examples: black stem rust, black vine weevils, pine shoot beetles, gypsy moths, and purple loosestrife). This rule also generally governs beekeeping.
  • 312 IAC 18-4 regulates nurseries, nursery stock, nurserymen, dealers, and agents
  • 312 IAC 18-5 sets fees for special services by the Division of Entomology and Plant Pathology
  • 312 IAC 18-6 considers trade secrets within documents filed with the Division of Entomology and Plant Pathology.
