The protease enzyme is a protein in the gut that helps the insect digest its main source of food: plant tissue. Many types of plants produce protease inhibitors, which inactivate proteases. Protease inactivation can lead to many issues such as reduced feeding, prolonged larval development time, and weight gain.
Distinct signal transduction pathway are activated in response either to insect damage or mechanical damage in plants. [23] While chemicals released in wounding responses are the same in both cases, the pathway in which they accumulate are separate. Not all herbivore attack begins with feeding, but with insects laying eggs on the plant.
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
Viburnum lesquereuxii leaf with insect damage; Dakota Sandstone (Cretaceous) of Ellsworth County, Kansas. Scale bar is 10 mm. Knowledge of herbivory in geological time comes from three sources: fossilized plants, which may preserve evidence of defense (such as spines) or herbivory-related damage; the observation of plant debris in fossilised animal feces; and the structure of herbivore mouthparts.
The bacterium Klebsiella aerogenes produces the volatile 2,3-butanediol, which modulates interactions between plants, pathogens, and insects. [48] When maize plants are grown in a soil culture containing the bacterium or the plants are inoculated with the bacterium, the maize is more resistant to the fungus Setosphaeria turcica. [48]
His research work was on the resistance of plants to insect attack and he pursued the idea of incorporating traits that increased host plant resistance to pest attack in the breeding of crop varieties. His landmark text on plant resistance to insects was Insect Resistance in Crop Plants (1951). In this book he identified three ways in which ...
Entomophily or insect pollination is a form of pollination whereby pollen of plants, especially but not only of flowering plants, is distributed by insects. Flowers pollinated by insects typically advertise themselves with bright colours, sometimes with conspicuous patterns (honey guides) leading to rewards of pollen and nectar ; they may also ...
