Dendrocerus
Dendrocerus is a genus of megaspilid wasps in the family Megaspilidae, comprising more than 100 described species. Members of this genus are hyperparasitoids, primarily attacking aphid parasitoids in the family Braconidae (Aphidiinae), particularly Aphidius species. The genus is characterized by elaborate branched antennae and specialized morphological adaptations for host location and exploitation. Some species exhibit nocturnal activity patterns and unique extrication structures for emerging from hosts.

Diaphania indica
cucumber moth, cotton caterpillar, leaf roller
Diaphania indica is a widespread moth species occurring primarily in tropical and subtropical regions of the Old World, native to southern Asia. It is a significant agricultural pest of cucurbitaceous crops, with larvae feeding on leaves, stems, and fruits of host plants. The species has been documented on multiple continents and is subject to biological control efforts using parasitoid wasps. Laboratory studies have established detailed demographic parameters and life cycle duration.

Dielis tolteca
Toltec scoliid wasp
Dielis tolteca is a species of scoliid wasp native to western North America and Mesoamerica. The species is known to parasitize scarab beetle grubs, with females hunting underground hosts to provision their offspring. Adults have been observed feeding on flowering plants, particularly mustards (Brassicaceae) and goldenrods (Solidago). The species has been documented in McInnis Canyons National Conservation Area in western Colorado, where it is active as a spring-emerging species.

Dysaphis
Dysaphis is a genus of aphids comprising over 100 species distributed across Europe, North America, and Australia. Species within this genus are primarily associated with dicotyledonous host plants, though some have been recorded on monocots. Several species are significant agricultural pests, particularly Dysaphis plantaginea (rosy apple aphid), which infests apple orchards. Like other aphids, Dysaphis species maintain an obligate nutritional symbiosis with the bacterium Buchnera, which enables them to subsist on phloem sap by synthesizing essential amino acids.

Eristalinus
Lagoon Flies
Eristalinus is a genus of hoverflies (family Syrphidae) characterized by distinctive spotted or banded eye patterns in most species. These stout, nimble fliers are distributed across Europe, Africa, Asia, and the Americas, with several species becoming widespread invasives outside their native ranges. The genus has undergone taxonomic revision, with molecular and morphological studies reorganizing former subgenera Eristalodes and Lathyrophthalmus into two primary clades. Species such as E. taeniops and E. aeneus are notable for their rapid global spread and potential as managed pollinators in agricultural systems.

Euborellia annulata
ring-legged earwig
Euborellia annulata is a predatory earwig species in the family Anisolabididae, originally described by Fabricius in 1793. It has been extensively studied as a biological control agent, particularly for lepidopteran pests in corn agroecosystems. The species exhibits five nymphal instars, sexual dimorphism in forceps size and predatory behavior, and is known for its aggressive predation on soft-bodied insect larvae and eggs.

Euhyponomeutoides
A genus of small moths in the family Yponomeutidae, established by Gaj in 1954. Contains seven described species distributed primarily in the Palearctic region. At least one species, Euhyponomeutoides albithoracellus, is a documented pest of black currant (Ribes nigrum) cultivation in Northern Europe. The genus is poorly studied, with limited biological information available for most species.

Eurytomidae
seed chalcids, eurytomid wasps
Eurytomidae is a family of chalcid wasps within the superfamily Chalcidoidea, comprising approximately 1,420 described species across 87 genera. Members exhibit diverse life histories: larvae are endophytic, developing within plant tissues (stems, seeds, or galls) as phytophages, parasitoids of other insects, or both. The family is cosmopolitan, occurring in virtually all terrestrial habitats. Some species are agricultural pests, notably the almond seed wasp (Eurytoma amygdali) and plum seed wasp (Eurytoma schreineri), while others serve as biocontrol agents. Phylogenomic studies have confirmed monophyly of the four recognized subfamilies (Buresiinae, Eurytominae, Heimbrinae, Rileyinae), though many large genera remain para- or polyphyletic.

Euschistus crenator
Euschistus crenator is a phytophagous stink bug (Hemiptera: Pentatomidae) recognized as a key pest in soybean cultivation, causing direct damage to developing grains. The species occurs across the Caribbean, Central America, North America, and South America, with confirmed populations in northern Brazil (Roraima and Pará states). Second-instar nymphs exhibit high susceptibility to entomopathogenic fungi, and the egg parasitoid Telenomus podisi has been confirmed to parasitize its eggs. The species is frequently misidentified with Euschistus heros due to morphological similarities.

Euschistus servus
Brown Stink Bug
Euschistus servus, commonly known as the brown stink bug, is a native North American pentatomid species distributed across Central America and North America. It is a significant agricultural pest in the southern United States, feeding on a wide range of crops including soybeans, cotton, corn, peanuts, peaches, and pecans. The species is highly mobile, capable of dispersing up to 15.9 km in flight mill studies, and exhibits seasonal movement between crop hosts and non-crop habitats. Two subspecies are recognized: E. s. servus and E. s. euschistoides.

Hyadaphis foeniculi
Fennel Aphid
Hyadaphis foeniculi is a cosmopolitan aphid species and major pest of fennel (Foeniculum vulgare), native to Mediterranean regions and introduced to Brazil and other areas. Laboratory studies demonstrate strict thermal requirements: nymph development occurs only between 15-30°C, with 3°C and 33°C lethal. The species exhibits four nymphal instars with temperature-dependent development rates, completing the nymphal stage in 5 days at 30°C to 19 days at 15°C. Winged adults reproduce parthenogenetically, forming colonies inside fennel flowers during hot periods. The aphid vectors at least 12 plant viruses and produces honeydew that facilitates sooty mold growth, compounding crop damage.

Lacunicambarus diogenes
devil crayfish, devil crawfish
Lacunicambarus diogenes, commonly known as the devil crayfish or devil crawfish, is a primary burrowing crayfish native to eastern North America. This species constructs and inhabits burrows in wet, muddy terrestrial habitats rather than living in permanent surface water. Its burrowing activities create refugia used by numerous other species, including documented use by eastern cicada killer wasps (Sphecius speciosus) as brooding habitat. The species ranges across the Atlantic Coastal Plain and Piedmont ecoregion from New Jersey to Georgia, with disjunct populations in Louisiana.

Melanocallis caryaefoliae
Black Pecan Aphid
Melanocallis caryaefoliae, commonly known as the black pecan aphid, is a specialized pest of pecan trees (Carya illinoinensis). Among aphid species attacking pecans, it produces the most severe foliar symptoms and achieves the highest mean density on susceptible cultivars. While feeding, it injects a toxin that causes bright yellow lesions between leaf veins, which subsequently turn brown and die. Premature defoliation from heavy infestations reduces nut fill and can diminish the following year's production. Unlike yellow pecan aphids, M. caryaefoliae is considered more destructive even at low densities, with economic thresholds as low as three aphids per compound leaf.

Melanoplus sanguinipes
migratory grasshopper, lesser migratory grasshopper, red-legged grasshopper
Melanoplus sanguinipes is a medium-sized spur-throated grasshopper and one of the most economically important grasshopper pests in North America. It is widely distributed across the continent, inhabiting diverse grassland habitats from native prairies to agricultural fields and disturbed areas. The species exhibits remarkable ecological flexibility, feeding on both grasses and forbs, and displays migratory behavior at high population densities. Under favorable conditions, populations can increase exponentially and form swarms that travel hundreds of miles, causing extensive damage to crops and rangeland. The species has been extensively studied for its population ecology, host plant relationships, and integrated pest management.

Meromyza americana
Wheat Stem Maggot
Meromyza americana, commonly known as the Wheat Stem Maggot, is a chloropid fly species whose larvae are significant pests of small grain cereals. The species completes a second generation in spring, with adults emerging to lay eggs on barley, oats, rye, wheat, and other grass hosts. Larval feeding occurs within stems, causing characteristic whitehead symptoms in infested tillers. Despite its pest status, infestations rarely exceed 1% of tillers, making insecticide treatments generally unnecessary.

Naupactus
White-fringed Weevils
Naupactus is a large genus of weevils in the family Curculionidae, commonly known as white-fringed weevils. The genus comprises exclusively Neotropical species, several of which have been introduced to other regions and become significant agricultural pests. Members of this genus are characterized by reduced humeri and lack of metathoracic wings, traits formerly used to separate them into the genus Graphognathus before taxonomic revision. Some species exhibit parthenogenetic reproduction, and flightless adults are common.

Neoaliturus tenellus
Beet Leafhopper
Neoaliturus tenellus, commonly known as the beet leafhopper, is a significant agricultural pest in western North America. This leafhopper species is a documented vector of Candidatus Phytoplasma trifolii (CPt) and beet curly top virus (BCTV), pathogens that affect potato, sugar beet, and other vegetable and seed crops. The species exhibits complex seasonal movement patterns between crop and noncrop hosts, utilizing weedy vegetation for overwintering and summer development. Its population dynamics and pathogen transmission ecology have been studied extensively in the Columbia River Basin and southern New Mexico to improve pest management forecasting.
