Leafminers
Larvae that live within and eat the tissue of leaves, creating distinctive tunnels or mines.
Locusts
Grasshopper like insects that can form swarms and consume large amounts of crops and foliage.
Wheat Stem Sawfly
Larvae bore into wheat stems, weakening the stalks and causing the heads to break off, which reduces yield.
Diamondback Moth
Larvae feed on cruciferous crops, creating holes in leaves and contaminating produce with their frass.
Flea Beetles
Small, jumping beetles that chew tiny holes in leaves, making a 'shothole' pattern, especially harmful to young plants.
Wireworms
Larvae of click beetles that live in the soil and feed on seeds and roots, leading to reduced germination and plant loss.
Potato Leafhopper
Small, wedge-shaped insects that cause 'hopperburn' on potato leaves, leading to curling, yellowing, and stunted plant growth.
Pink Bollworm
Larvae that infest cotton bolls, causing lower yield and quality of cotton fiber.
Aphids
Small sap-sucking insects that can cause yellowing and distorted growth in plants. They often produce a sticky substance called honeydew.
Mexican Bean Beetle
A pest that eats the undersides of bean leaves, leaving behind a lacy skeleton and reduced plant vigor.
Western Corn Rootworm
Beetles whose larvae feed on corn roots, reducing nutrient uptake and causing plant lodging.
Woolly Apple Aphid
Aphids that produce a woolly wax covering, infesting apple trees and causing galls and stunted growth.
Scale Insects
Sap-feeding insects covered with a waxy coating, causing yellowing, stunting, and premature leaf drop in infested plants.
Potato Tubeworm
A pest that bores into tubers, causing direct damage and opening entryways for disease.
Russian Wheat Aphid
Pest that damages wheat by injecting toxins into the plant, causing leaf curling and stunted growth.
Spider Mites
Tiny arachnids that feed on plant fluids, leading to speckled leaves and potentially defoliation.
Stink Bugs
Shield-shaped insects that feed on fruits, vegetables, and crops, causing spots and distortions.
Thrips
Tiny insects that scrape and suck plant cells, causing silver-white streaks and spots on leaves and flowers.
Fall Armyworm
Caterpillars that devastate crops by eating leaves, stems, and reproductive parts, often leading to significant yield loss.
Boll Weevil
A beetle that feeds on cotton buds and flowers. Known for severe damage to cotton crops leading to boll rot.
Nematodes
Microscopic roundworms that can cause root damage, leading to stunted growth and reduced yield.
Whiteflies
Small, white insects that feed on plant sap, causing wilting, yellowing, and stunted growth, and produce honeydew.
Corn Earworm
Larvae that feed on a variety of plants, most notably corn ears, leading to loss of yield and grain quality.
Japanese Beetle
A highly destructive pest known for skeletonizing leaves and damaging a wide variety of plants.
Tomato Hornworm
Large green caterpillars that devour leaves and fruits of tomato plants and other nightshades.
Armyworm
Caterpillars that consume large quantities of foliage, often in a 'marching' fashion which is destructive to crops like corn, rice, and wheat.
Zebra Caterpillar
Caterpillars with distinctly striped bodies that feed on a variety of vegetable crops, leading to foliage loss.
European Corn Borer
A moth whose larvae bore through corn stalks, reducing the plant's structural integrity and yield.
Fruit Flies
Insects that lay eggs in ripening fruit, leading to wormy fruit and secondary infections.
Hessian Fly
Larvae that infest wheat stems, causing weakness and sometimes breaking, known as 'lodging,' which reduces yield.
Codling Moth
Larvae bore into apples and pears, causing internal damage and fruit rot.
Rice Water Weevil
Beetles whose larvae feed on rice roots, leading to reduced growth and yield.
Gypsy Moth
Caterpillars known for voracious eating habits that defoliate a wide range of hardwood trees, leading to tree stress and mortality.
Peach Tree Borer
Larvae bore into the base of stone fruit trees, causing gumming and sawdust-like frass, potentially killing the tree.
Squash Vine Borer
Larvae that tunnel into squash and pumpkin vines, causing wilting and death of the plant.
Stem Borers
Larvae that bore into stems and branches, impairing water and nutrient transport within the plant.
Bagworm
Larvae that construct distinctive protective cases out of silk and plant materials, defoliating trees and shrubs.
Colorado Potato Beetle
Leaf beetle that defoliates potato plants and can rapidly develop resistance to insecticides.
Mealybugs
Soft-bodied insects that feed on plant sap and excrete honeydew, can lead to sooty mold and weakened plants.
