Phytophaga is a clade of beetles within the infraorder Cucujiformia consisting of the superfamilies Chrysomeloidea and Curculionoidea that are distinctive in the plant-feeding habit combined with the tarsi being pseudotetramerous or cryptopentamerous, where the fourth tarsal segment is typically greatly reduced or hidden by the third tarsal segment.
The generic and English name thrips is a direct transliteration of the Ancient Greek word θρίψ, thrips, meaning "woodworm". [4] Like some other animal-names (such as sheep, deer, and moose) in English the word "thrips" expresses both the singular and plural, so there may be many thrips or a single thrips. Other common names for thrips ...
Phenolic compounds can act as protective agents, inhibitors, natural animal toxicants and pesticides against invading organisms, i.e. herbivores, nematodes, phytophagous insects, and fungal and bacterial pathogens. The scent and pigmentation conferred by other phenolics can attract symbiotic microbes, pollinators and animals that disperse fruits.
Imago are phytophagous, sometimes feeding on microscopic algae and bacteria (Paracoenia, Ephydra), or predatory (Ochthera, Ephydrinae). As larvae, many are phytophagous, grazing on aquatic plants (including cultivated rice), others are algal grazers or saprophagous. Larvae of Trimerina are predatory. Some species are an important food source ...
It is found in east and southeast Asia. It is one of the most widely distributed phytophagous insect pests in Asia, and feeds on dozens of host plants including a number of economically important fruits, such as apples, cherries, pears and kiwifruit.

These types of ant-insect interactions involve the ant providing some service in exchange for nutrients in the form of honeydew, a sugary fluid excreted by many phytophagous insects. . [5] Interactions between honeydew-producing insects and ants is often called trophobiosis , a term which merges notions of trophic relationships with symbioses ...
They are also called phytophagous insects. These insects may eat essential parts of the plant, such as the leaves or sap, or they may survive on the pollen and nectar produced by the plant. These insects will compete with other organisms for limited plant host in an environment where there is constant change in plant availability and quality. [20]
This potential, however, can hinge on a number of the insect's traits. For example, hemipteran predators can use their sucking mouthparts to make use of leaves, stems, and fruits, but spiders with chelicerae cannot. [17] Still, insects widely considered to be purely carnivorous have been observed to diverge from expected feeding behavior. [18]
