Species are almost exclusively associated with host plants in Brassicaceae and related families in the order Brassicales, with 18% of species feeding on multiple families within this order. Many species are economically significant agricultural pests, particularly of crucifer crops including canola, cabbage, and turnip. The genus has independently colonised Brassicaceae and exhibits adaptations to the characteristic chemical defences (glucosinolates) of these host plants.
Phylloxera
phylloxeras
Phylloxera is a genus of tiny, soft-bodied, sap-sucking insects in the family Phylloxeridae, closely related to aphids. The genus includes economically significant agricultural pests, most notably the grape phylloxera (Daktulosphaira vitifoliae), which devastated European vineyards in the late 19th century and remains a major threat to viticulture worldwide. Phylloxera species induce characteristic galls on host plants through chemical secretions that manipulate plant tissue development. The genus exhibits complex life cycles involving multiple morphological forms, including winged and wingless parthenogenetic generations and a brief sexual generation.
Phylloxera caryaefallax
pecan leaf phylloxera
Phylloxera caryaefallax, commonly known as the pecan leaf phylloxera, is a small, soft-bodied, gall-forming insect closely related to aphids. It is a significant pest of pecan trees (Carya illinoinensis), causing distinctive galls to form exclusively on leaf tissue. Unlike the related pecan phylloxera (Phylloxera devastatrix), which attacks shoots and nuts and causes more severe economic damage, this species is generally less destructive though heavy infestations can cause defoliation. The insect has a complex life cycle involving multiple generations per season and overwinters as eggs protected within the bodies of deceased females.
Phylloxera caryaesepta
pecan leaf phylloxera, pecan phylloxera
Phylloxera caryaesepta is a tiny, soft-bodied insect in the family Phylloxeridae, closely related to aphids. It is a significant pest of pecan trees (Carya illinoinensis), forming conspicuous galls on leaves, twigs, and nuts. The species survives winter as eggs in bark crevices, with nymphs emerging during spring bud break to feed on new growth. Unlike the related pecan leaf phylloxera (Phylloxera notabilis) which attacks only leaves, P. caryaesepta damages shoots and nuts, making it more economically destructive. Heavy infestations can reduce yield, impair tree vitality, and curtail subsequent production.
Phylloxera deplanata
pecan leaf phylloxera, pecan phylloxera
Phylloxera deplanata is a tiny, soft-bodied insect in the family Phylloxeridae, closely related to aphids. It is a significant pest of pecan trees (Carya illinoinensis), causing the formation of galls on leaves, shoots, and nuts. The species overwinters as eggs in bark crevices and emerges in spring to feed on new growth, inducing abnormal plant tissue development. Unlike the pecan leaf phylloxera (which forms galls on leaves only), this species attacks shoots and nuts, making it more economically damaging. Heavy infestations can reduce yield, impair tree vitality, and diminish subsequent production.
Phytoseiidae
predatory mites
Phytoseiidae is a large family of predatory mites in the order Mesostigmata, comprising over 2,700 described species across 90 genera and three subfamilies (Amblyseiinae, Phytoseiinae, and Typhlodrominae). These mites are primarily recognized for their role as biological control agents against agricultural pests, particularly spider mites (Tetranychidae), thrips, and other small arthropods. Their effectiveness in integrated pest management programs has driven substantial research interest, with species such as Phytoseiulus persimilis, Neoseiulus californicus, and Amblyseius swirskii among the most widely studied and commercially deployed predatory mites.

Picromerus is a genus of predatory shield bugs in the family Pentatomidae. Species in this genus are predatory throughout their life cycle, feeding primarily on lepidopteran larvae and other soft-bodied insects. Several species, particularly P. bidens and P. lewisi, have been studied extensively for their potential as biological control agents against agricultural and forest pests. The genus exhibits specialized adaptations for predation, including well-developed olfactory systems for locating prey and host plants.
Piezodorus guildinii
Red-banded Stink Bug, Redbanded Stink Bug, Small Green Stink Bug, Alfalfa Bug
Piezodorus guildinii, commonly known as the red-banded stink bug, is a pentatomid stink bug native to the Neotropics that has become a significant agricultural pest in the southern United States since around 2000. It is smaller and more agile than other stink bug pests, with documented resistance to multiple insecticide classes. The species causes substantial economic damage to soybean and other legume crops through sap feeding on seeds, pods, flowers, stems, and leaves, and has been linked to delayed maturity syndrome in soybeans.
Pineus pinifoliae
Pine Leaf Adelgid, Pine Leaf Aphid, Pine Leaf Chermid
Pineus pinifoliae is a small, phloem-feeding insect in the family Adelgidae, commonly known as the pine leaf adelgid or pine leaf aphid. It has a complex life cycle involving alternation between spruce (Picea) as the primary host, where it forms galls on new shoots, and white pine (Pinus strobus) as the secondary host. The species produces multiple generations annually, with distinct morphological forms including winged migrants that transfer between hosts. Heavy infestations on white pine cause characteristic damage patterns including needle stunting, reduced radial growth, and branch mortality concentrated in the lower and mid-crown.
Pityogenes
bark beetles
Pityogenes is a genus of bark beetles in the family Curculionidae, comprising over 30 described species distributed across the Northern Hemisphere. Species in this genus are primarily associated with coniferous trees, with P. chalcographus being the most extensively studied due to its economic significance as a pest of Norway spruce. The genus exhibits typical scolytine characteristics including aggregation pheromone communication and specialized host-finding behaviors. Some species demonstrate notable geographic variation in morphology and genetics, suggesting population differentiation across their ranges.
Platynus
Platynus is a genus of ground beetles in the family Carabidae containing over 180 described species. Species in this genus are primarily nocturnal predators with well-developed olfactory capabilities. The genus has been extensively studied in ecotoxicological research due to its role as a beneficial predatory insect in agricultural ecosystems. Several species have been used as model organisms to assess sublethal effects of insecticides on non-target beneficial arthropods.
Platypalpus
dance fly, hybotid dance fly
Platypalpus is a large genus of hybotid dance flies comprising at least 580 described species worldwide, with over 200 species in Europe alone. These small predatory flies are characterized by their compact bodies, enlarged compound eyes that occupy most of the head, and raptorial front legs adapted for seizing prey. Adults are active predators that feed on small insects, while larvae occupy diverse microhabitats including leaf litter, soil, and aquatic environments. The genus has been documented in agricultural ecosystems, particularly cereal crops and greenhouses, where they may contribute to pest regulation.
Podisus maculiventris
Spined Soldier Bug
Podisus maculiventris, the spined soldier bug, is a native North American predatory stink bug widely studied for biological control applications. It is a generalist predator of over 70 insect species, including agricultural pests such as the Colorado potato beetle, Mexican bean beetle, and brown marmorated stink bug. Unlike plant-feeding stink bugs, it actively hunts and kills prey using toxic venom and digestive enzymes. Adults overwinter and become active on warm winter days. The species has been extensively researched for augmentative release in agricultural systems, particularly against coleopteran and lepidopteran larvae.
Polistes dominula
European Paper Wasp
Polistes dominula is a highly successful invasive social wasp native to Eurasia that has established populations across North America, South America, New Zealand, South Africa, and other regions. First detected in North America near Boston in 1978, it has become one of the most abundant wasps on the continent. The species builds small, exposed paper nests in protected locations and preys primarily on live insects, particularly caterpillars. Unlike yellowjackets, it does not scavenge for meat or sugar. Its rapid spread has been attributed to ecological flexibility, superior competitive ability, and tolerance of human-altered environments.
