The term is usually associated with insect dietary behaviour. [2] Organisms may exhibit narrow or specific oligophagy where the diet is restricted to a very few foods or broad oligophagy where the organism feeds on a wide variety of specific foods but none other. [3] Polyphagy, on the contrary, refers to eating a broad spectrum of foods. In the ...

Although some insects are polyphagous, many are restricted to one specific crop, or group of crops. In many cases it is the larva that feeds on the plant, building up a nutritional store that will be used by the short-lived adult; sawfly and lepidopteran larvae feed mainly on the aerial portions of plants while beetle larvae tend to live ...
Fiorinia fioriniae is a highly polyphagous scale insect and widely distributed around the world, being found in Asia, Australia/Pacific, Africa, Europe and the Americas. Its vernacular names include fiorinia scale, palm fiorinia scale, and avocado scale.
More than 100 insect species prey on H. zea, usually feeding on eggs and larvae. [24] The insidious flower bug (Orius insidiosus), a pirate bug, feeds on the eggs of H. zea, thus acting as a biological control agent. [24] Some plants emit a blend of chemicals in response to damage from H. zea, which attract parasitic insects. [25]
Trichogramma is a genus of minute polyphagous wasps that are endoparasitoids of insect eggs. [1] Trichogramma is one of around 80 genera from the family Trichogrammatidae, with over 200 species worldwide. [2] [3] [4]
