The topic of plant–insect interactions includes a wide range of relationships, such as herbivory, insect pollination, and plant provision of food and shelter to insects. … Some plants can also provide shelter to insects that feed on other plants or on other organisms.
What is the interaction between insect and flower?
During pollination, an insect moving within a flower to obtain nectar may transfer pollen either within that flower or among other flowers on that plant. Other relationships between insects and plants can be detrimental to the plant but beneficial to the insect (e.g., herbivory, or feeding upon the plant).
How do insects affect plants?
They have a direct impact on agricultural food production by chewing the leaves of crop plants, sucking out plant juices, boring within the roots, stems or leaves, and spreading plant pathogens. They feed on natural fibers, destroy wooden building materials, ruin stored grain, and accelerate the process of decay.
What do insects take from plants?
Insects typically pollinate flowers as they move from plant to plant searching for food. Many flowers produce nectar, a sugary liquid that many insects eat. When an insect lands on a flower to feed, pollen grains stick to its body.
What do you think is the relationship between ants and plants?
A healthy relationship
Myrmecophytes, otherwise known as ant-plants, share a mutualistic relationship with a colony of ants. … Myrmecophytes have structural adaptations to their rhizomes, leaves and stems that provide ants with food and shelter, and in return, ants assist them with nutrition, defence and seed dispersal.
What is the relationship between plants?
Mutualism. Mutualism is an obligate interaction between organisms that requires contributions from both organisms and in which both benefit. There are many examples in nature. Pollination and dispersal, discussed above, are mutualistic because both plant and pollinator or disperser benefit from the relationship.
How insects are useful to humans and plants?
Insects create the biological foundation for all terrestrial ecosystems. They cycle nutrients, pollinate plants, disperse seeds, maintain soil structure and fertility, control populations of other organisms, and provide a major food source for other taxa.
What are the harmful effects of insects to humans?
Insect bites generally have a couple harmful effects — irritation and illness. The less severe effect is the simple irritation, swelling and pain that sometimes come from bites by certain insects such as mosquitoes, bees and some spiders.
Do insects kill plants?
However, insects seldom destroy these plants. The threat of damage by insects need not prevent an attempt to grow any of these plants. A knowledge of what to expect and how to control the pests when they are destructive enables anyone to tolerate low numbers of insects. Some insects are perennial pests.
Which insect destroy crops?
Aphids. How it Kills: Also known as plant lice, they are diminutive, soft bodied, pear shaped insects which suck sap, typically during the spring and summer seasons. Severe infestation results in curling of leaves, stunted growth and gradual drying and death of young plants.
