Arhopalus
burnt pine longhorn beetle (A. ferus), black pine sawyer (A. rusticus)
Arhopalus is a genus of longhorn beetles (Cerambycidae: Spondylidinae: Asemini) distributed across the Northern Hemisphere, with several species introduced to the Southern Hemisphere as invasive pests of conifers. The genus comprises approximately 20 described species, with A. rusticus and A. ferus being the most extensively studied due to their economic importance. Species develop in dead or fire-damaged conifer wood, with some exhibiting strong attraction to burnt pine volatiles. Several species produce male-emitted aggregation-sex pheromones containing fuscumol and geranylacetone. Invasive populations in New Zealand, Australia, South America, and South Africa require monitoring at ports and sawmills for timber export compliance.

Dacne picta
Dacne picta is a small beetle in the family Erotylidae (pleasing fungus beetles). It has been documented as a major pest of cultivated shiitake mushrooms (Lentinula edodes), with laboratory studies demonstrating chemotactic behavioral responses to host odors from all growing stages of the mushroom. The species has a broad geographic distribution spanning North America, Oceania, and Southern Asia.

Lygus hesperus
Western Tarnished Plant Bug
Lygus hesperus is a significant agricultural pest in western North America, causing extensive damage to cotton, strawberries, alfalfa seed, and other crops. In California alone, annual losses exceed $30 million in cotton and $40 million in strawberries. Adults overwinter in reproductive diapause triggered by short day lengths, resuming activity when conditions improve. The species has been the subject of extensive research on sampling methods, biological control, and insecticide resistance.

Thanasimus dubius
dubious checkered beetle, American bark beetle destroyer, checkered beetle predator, Wavering Checkered Beetle
Thanasimus dubius is a predatory checkered beetle (Cleridae) native to North and Central America. It specializes in preying upon bark beetles, particularly species in the genera Ips and Dendroctonus, with the southern pine beetle (Dendroctonus frontalis) being a well-documented prey item. Adults exhibit a stereotyped five-act predatory sequence involving search/ambush, seizure, alignment, consumption, and grooming. The species demonstrates chemotactic responses to bark beetle pheromones and tree volatiles, and shows regional genetic differentiation across its eastern North American range. It has been investigated as a potential biological control agent for forest pest management.
