Host plant predictability and the feeding patterns of monophagous, oligophagous, and polyphagous insect herbivores. Able, K.W., (1999). Direct competitors usually are not closely related to each other (phylogenetically) and their association tends to be relatively recent in origin and short-lived in duration compared to more symbiotic (mutualistic) interactions. Some of these insects must rely on intestinal symbionts to supply essential dietary components that are not supplied by their host (see Insect Nutrition). Hence, more studies on non-pest species are needed to understand the complexity of insect–plant interactions of these important frugivorous insects. Larvae of monophagous and oligophagous herbivores preferred young leaf tissues while, overall, larvae of polyphagous species preferred mature leaves of their various host plants. (2007) have recently demonstrated the concept of using transgenic plants expressing insect-specific dsRNAs as an insect control strategy. Entomologists frequently use the noun "phytophagy" and the adjective "phytophagous" when referring to any of these nutritional strategies.

Insect, aphids are polyphagous (feed on more than one plant species) or monophagous (feed on a particular species of plant). In other words, animals which eat only one type of food are called monophagous. It has also been used as a model system for ecological studies and for developing effective pest management. eCollection 2020.

Development and fecundity performance of Grapholita molesta and Grapholita dimorpha (Lepidoptera: Tortricidae) on different immature fruits. For example, plants in the cabbage family contain sulfur-containing compounds that act as sign stimuli for insects that habitually feed on only these plants. It can be metabolically "expensive" to produce these enzymes, but on the other hand, there is no shortage of available food! Which of the following are the main characteristic features of an Insect?

Why some phytophagous insects are monophagous (specialists) and others are polyphagous (generalists) is a much-debated question in entomological circles. Of the 16 populations that increased, all are monophagous on the crop in the regions in which they were studied. 2019 May 31;14(5):e0217492. Examples of insect species with different diet breadths from the main orders of insects The term “polyphagy” does not imply that the insect will eat any plant species.
