What are the examples of phytophagous insects?
The most important phytophagous families of flies are Cecidomyiidae (gall flies), Agromyzidae (leaf miners) and Tephritidae (fruit flies). Amongst the Hymenoptera, all Symphyta (sawflies and related insects) are plant feeders, while gall wasps occur in the Cynipoidea.
Why are insects so speciose?
Scientists show that many insect groups like beetles and butterflies have fantastic numbers of species because these groups are so old. In contrast, less diverse groups, like mammals and birds, are evolutionarily younger. In contrast, less diverse groups, like mammals and birds, are evolutionarily younger.

What are phytophagous mites?
Phytophagous mites are serious pests in indoor and outdoor agricultural ecosystems and are controlled by synthetic pesticides. Pesticides adversely affect natural enemies and lead to environmental pollution, human health problems, harmful side effects, and risk of pest resistance.
Are ants bees?
Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants appear in the fossil record across the globe in considerable diversity during the latest Early Cretaceous and early Late Cretaceous, suggesting an earlier origin.

Which is an example of a monophagous pest?
Monophagous Pests– are those insects which are known to feed on only a single species of plants. Tryporyza incertulus is a monophagous pest and attacks only on paddy plants. Oligophagous Pests– are insects confine their feeding activity to plants belonging to one taxonomic group i.e., one family. A well known example is the cabbage butterfly.
