from The Century Dictionary and Cyclopedia
- Feeding on a single substance, or a single kind of food: opposed to heterophagous.
- Specifically, of sporozoans, passing the entire life-cycle in one host; permanently intracellular: contrasted with polyphagous.
One must know that the brinjal fruit and shoot borer (Leucinodes orbonalis) is also a characteristic monophagous insect (single host pest) and will naturally try to struggle to withstand bacterial toxins.
Most phytophagous insects are diet specialists, i.e., they feed on one or a few plant species that are closely related (monophagous, host plants within one plant genus, or oligophagous, host plants within one family) .
