Indian meal moth
The Indian meal moth is a widespread stored-product pest that infests grains, nuts, dried fruits, and processed foods. Larvae cause direct feeding damage and contaminate commodities with silk webbing and frass. Effective management relies on sanitation, monitoring, and targeted treatments.
View Profile
Internode Borer
The internode borer is a destructive stem-boring pest primarily targeting sugarcane, rice, and other graminaceous crops, causing significant yield losses through tunneling that weakens stalks and promotes rot. Early detection of characteristic 'dead hearts' and frass is crucial for effective management. This guide provides comprehensive diagnostics, organic control strategies, and prevention tactics for farmers.

Ips engraver beetles
Ips engraver beetles are aggressive bark beetles that attack stressed or recently damaged conifers, creating characteristic galleries under the bark that disrupt nutrient flow and rapidly kill trees. These native pests can trigger localized outbreaks after storms, drought, or thinning operations when populations build in slash and move to healthy hosts.
View Profile
Iris borer
The iris borer is a destructive moth larva that tunnels into iris rhizomes, causing wilting, rot, and plant death. Early detection and integrated management are essential for protecting iris plantings in home and commercial gardens.

Japanese beetles
Japanese beetles (Popillia japonica) are invasive pests notorious for skeletonizing leaves and damaging over 300 plant species in North America. Adults feed in groups on foliage, flowers, and fruits, while larvae destroy turf and crop roots. This guide provides expert diagnostics, organic management, and prevention strategies for farmers and gardeners.

Jassids
Jassids, also known as leafhoppers, are tiny sap-sucking pests that cause significant damage to crops like cotton, rice, and vegetables by feeding on plant sap and transmitting diseases. They produce characteristic hopperburn symptoms, leading to yellowing, curling, and necrosis of leaves. Effective management combines cultural practices, organic treatments, and vigilant monitoring for sustainable control.

June drop beetles
June drop beetles, also known as June bugs or May beetles, are large scarab beetles notorious for their sudden mass emergences in early summer, swarming lights and dropping from trees onto crops below. Their larvae, called white grubs, cause extensive root damage to lawns, pastures, and field crops, leading to wilting and plant death. Effective management combines cultural practices, biological controls, and targeted organic treatments for long-term prevention.

kernel-feeding insects
Kernel-feeding insects are a diverse group of pests that target the developing grains or seeds of cereal crops, causing significant yield losses through direct feeding and secondary infections. Common culprits include corn earworm, European corn borer, and maize weevils, thriving in warm, humid conditions. Effective management combines monitoring, cultural practices, and targeted organic controls to protect crop integrity.
View Profile
lace bugs
Lace bugs are tiny, lace-winged pests that suck sap from leaf undersides, causing stippling, bronzing, and leaf drop in ornamental trees and shrubs. Common on broadleaf evergreens like azaleas, rhododendrons, and oaks, they thrive in hot, dry conditions and can defoliate plants if unmanaged. Effective organic controls include horticultural oils, insecticidal soaps, and natural predators like predatory mites.

lady beetles
Lady beetles are beneficial predatory insects widely used in integrated pest management for controlling aphids and other soft-bodied pests. While they rarely cause damage, certain species can become nuisance invaders in homes or occasionally feed on ripening fruit during food scarcity.
View Profile
ladybugs
While ladybugs are celebrated beneficial insects for devouring aphids and other pests, certain invasive species like the Asian lady beetle can become agricultural nuisances by infesting overwintering sites near crops and contaminating harvests with bitter-tasting alkaloids. This guide provides diagnostic tools, lifecycle insights, and organic management strategies to mitigate ladybug issues in farming operations. Learn prevention tactics to protect your fields without harming these mostly helpful predators.
