Crop Protection and Entomology Review

Flashcards covering key vocabulary and definitions related to crop protection and entomology.

The science and practice of managing plant diseases, weeds, and other pests that damage agricultural crops and forestry.

Crop Protection

The study of insects, derived from the Greek word 'entomon' meaning insect.

Entomology

The study of the comparative anatomy of insects.

Insect Morphology

A perennial pest that usually has a higher reproductive potential.

Key Pest

A pest that annually reduces yield but seldom causes epidemics.

Chronic Pest

Pests that initiate damage, making seeds vulnerable to further attacks.

Primary Pests

Pests that follow primary pests in infesting products or crops.

Secondary Pests

Pests that occur when given a favorable environment and a susceptible host.

Potential Pests

The process of egg production by the female insect.

Oogenesis

The process of transformation insects undergo from larval stages to adult forms.

Metamorphosis

A type of development in insects characterized by complete metamorphosis.

Holometabola

A type of development characterized by gradual metamorphosis in insects.

Paurometabola

Describes an insect species that produces one generation per year.

Univoltine

Describes an insect species that produces more than one generation per year.

Multivoltine

A method of collecting insects through techniques like sweep netting and foliage beating.

Active Collection

A method of collecting insects using traps set to attract or intercept them.

Passive Collection

A plant deemed undesirable in a certain context, often competing with cultivated crops.

Weed

Plants that complete their life cycle within one growing season.

Annual Weeds

Plants that complete their life cycle in two years.

Biennial Weeds

Plants that survive for more than two years and reproduce vegetatively or by seeds.

Perennial Weeds

Using biological agents to control pest populations.

Biological Control

The study of insects that are economically important, whether beneficial or harmful.

Economic Entomology

The study of the effects and mechanisms of chemical agents used to control insects.
