What are the insect pests in plants?
Common pests like aphids, thrips, caterpillars, spider mites, and whitefly can lead to damaged plants and reduced yields. Our commitment is to provide growers around the world with extensive knowledge and natural solutions to manage and prevent pests. Insects*: such as aphids, caterpillars, or beetles that damage crops or spread disease. Rodents*: such as rats or mice that damage crops, property, or spread disease. Weeds*: plants that compete with crops for resources like water, nutrients, or light.Pests include insects, nematodes, mites, snails, slugs, etc. Depending upon the importance, pests may be agricultural forest, household, medical, aesthetic and veterinary pests.A pest is classed as an animal which could be harmful to humans. They may for example damage crops, livestock or forestry, cause a nuisance by invading homes and work spaces or cause illness by spreading disease. There are four different types of pests – rodents, insects, birds and wildlife.An agricultural pest is any organism that reduces the yield or quality of crops. This can include insects, mites, weeds, nematodes, fungi, bacteria, viruses, birds, mammals, and even other plants.Agricultural and horticultural crops are attacked by a wide variety of pests, the most important being rodents, insects, mites, nematodes and gastropod molluscs.

Other notable pests are white grubs, cutworms, grasshoppers, and leaf-eating beetles.What are the most common agricultural pests?

What are the big 4 insects?
BIG4. These ‘big four’ insect groups constitute about half of all living species on Earth and have an enormous impact on natural or anthropogenic ecosystems, even when not visible as such by a layman. The most diverse insect orders are the Hemiptera (true bugs), Lepidoptera (butterflies and moths), Diptera (true flies), Hymenoptera (wasps, ants, and bees), and Coleoptera (beetles), each with more than 100,000 described species.Examples of insects are dragonflies, flies, fleas, butterflies, moths, cicadas, beetles, bees, ants, and wasps. Most insects undergo metamorphosis. That’s when a grub-like larva transforms into a very different-looking adult.
What is the most common insect?
Insect. It hardly comes as a surprise that ants are the most numerous insect in the world. These colonial hymenopterans may number from 10-100,000 trillion individuals globally; there are more than 10,000 species. According to the Smithsonian Institute, at any given time there are some 10 quintillion (10,000,000,000,000,000,000) individual insects alive. Recent estimates suggest there are more than 200 million insects for each person on the Earth.Phytophagous insects are highly diverse and the total species number is at least 500,000. This represents about 25% of known multicellular animals.
