Insect ecology is the interaction of insects, ... They are also called phytophagous insects. ... (intraspecific) or between species (interspecific). This competition ...
Robert F. Denno (1945–2008) was an influential insect ecologist. [1] He published more than 130 research papers [2] that helped advance the study of plant–insect interactions, interspecific competition, predator prey interactions and food web dynamics. He studied the ecology of sap-feeding insects, both in natural and cultivated settings. [1]
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 partners have coevolved through geological time; in the case of insects and flowering plants, the coevolution has continued for over 100 million years. Insect-pollinated flowers are adapted with shaped structures, bright colours, patterns, scent, nectar, and sticky pollen to attract insects, guide them to pick up and deposit pollen, and ...
Specifically, Bush reasoned that phytophagous insects that both consume and reproduce on specific host plants provide opportunities for speciation without strict geographical isolation (as in allopatric speciation) because, as the insects adapt to feeding on a new host plant, they are also more likely to mate with other members of their species ...
Other insect species which have been introduced pose a risk for endangering giant wētā species through competition for resources. [ 33 ] Introduced species may compete with the wētā for food and habitats, potentially causing the resources to reach capacity, inhibiting further population growth.
These bugs are phytophagous, polyphagous or oligophagous, mainly associated with the Fabaceae, but can also feed on plants of other families. Some may feed on fungi. Some may feed on fungi. They harbor microorganisms in their digestive tract, specific to each host species, living in symbiosis with it.
