Against adult insects
_______ marking locations of cases where the diseases are abundant suggesting endemicity of the species.
Taxonomic classification
body divisions, type and number of legs, if present -type and number of antennae (presence or absence of antennae is also an identifier), type of mouthparts (mandibulate or proboscis),
External morphology
type of metamorphosis, oviposition and biology (structure and function) of the eggs, larva, pupa and adult forms, Habitats and behaviors
Life cycle
role in the occurrence of disease cases: as vectors, physical afflictions, allergies
Medical importance
Physical (filing in , source reduction, draining, larval habitats and other possible breeding sites), Chemical (oils, insecticides, IGRs, or any combination of both, Genetics, environmental manipulation, IPM
Control
insect repellent lotions, insect screens and treated nets, spray guns, Aerosols, mists/fogging, indoor residual spray.
Against adult insects

chitin
Molting or _____
Ecdysis
Enumerate body divisions:
- Head
