Study Notes

Physiology and Toxicology

Physiology studies the functions of living organisms and their parts.
Toxicology focuses on the impacts, detection, and antidotes of poisons.

Insect Physiology

Insects are self-replicating metabolic systems, similar to other life forms such as weeds and pathogens.

Abdomen: Posterior part of the insect body.
Antennae: Paired sensory organs on the insect's head.
Apex: Farthest point from the base of a body part.
Bionomial: Scientific name comprising two parts.
Carina: Elevated ridge on an insect's surface.
Coleoptera: Order of insects known as beetles, meaning sheath-winged.

Anatomical Features

Concave: A hollowed or depressed area; Convex: Curved outward.
Elytra: Hard shell formed from the first pair of modified wings.
Frons: Upper anterior portion of the insect's head.
Mandibles: Insects’ first pair of jaws.

Developmental Terms

Diapause: A state of suspended animation where no development occurs.
Larva/Larvae: Immature stage of juvenile insects.
Moult: Shedding of outgrown skin during larval growth.

Functional Roles in Ecology

Fungal feeder: Insects that feed primarily on fungi associated with stored grain.
Scavenger: Organisms that consume decaying or waste matter.

Insect Body Structure

Mesothorax: Middle thorax segment, supports middle legs and first pair of wings.
Metathorax: Last thorax segment, supports hind legs and second pair of wings.
Pronotum: Dorsal surface of the prothorax appearing as mid-segment from above.

Term Clarifications

Ocellus: A simple eye with a single lens in adult insects.
Punctures: Small impressions on the insect's outer body.
Pubescence: Short, soft hairs on the insect surface.
Terga/Tergum: Upper surface of body segments; multiple segments (terga) vs. one segment (tergum).

Morphological Terms

Crenulate: Having small scallops or rounded edges.
Serate(d): Saw-like or toothed structure.
Sub-basal: Below the attachment point of a structure.

Miscellaneous Terms

Horns: Pointed projections on the head.
Temple: Area between the eye and the back of the head.
Tubercle: Small bumps or projections on a surface.
Urogomphi: Structures found on the terminal segment of certain insects.
