Euphorbia is a very large and diverse genus of flowering plants, commonly called spurge, in the family Euphorbiaceae. "Euphorbia" is sometimes used in ordinary English to collectively refer to all members of Euphorbiaceae, not just to members of the genus.
Euphorbia esula, commonly known as green spurge or leafy spurge, is a species of spurge native to central and southern Europe, and eastward through most of Asia north of the Himalaya to Korea and eastern Siberia. It can also be found in some parts of Alaska.
Aphthona flava is a beetle of the genus Aphthona. It is native to Eurasia, and has been introduced into North America as a biocontrol agent for leafy spurge. Adults are brown and difficult to distinguish in the field from A. cyparissiae and A. nigriscutis. A. flava is still the dominant beetle at some Manitoba release sites, but it is relatively scarce in North Dakota and Minnesota. Besides Manitoba, it is widespread in Hungary and Italy.
Euphorbia cyparissias, the cypress spurge, is a species of plant in the genus Euphorbia. It is native to Europe and was introduced to North America in the 1860s as an ornamental plant.
Euphorbia myrsinites, the myrtle spurge, blue spurge, or broad-leaved glaucous-spurge, is a succulent species of flowering plant in the spurge family Euphorbiaceae.
The flea beetle is a small, jumping beetle of the leaf beetle family (Chrysomelidae), that makes up the tribe Alticini which is part of the subfamily Galerucinae. Historically the flea beetles were classified as their own subfamily.
Zygogramma is a large genus of leaf beetles in the subfamily Chrysomelinae, which includes approximately 100 species. 13 species occur north of Mexico.
Agasicles hygrophila is a species of leaf beetle known by the common name alligator weed flea beetle. It has been used successfully as an agent of biological pest control against the noxious aquatic plant known as alligator weed.
Aphthona abdominalis is a species of leaf beetle known as the minute spurge flea beetle. It was used as an agent of biological pest control against the noxious weed leafy spurge, but never established a viable population.
Aphthona cyparissiae is a species of leaf beetle known as the brown dot leafy spurge flea beetle. It is used as an agent of biological pest control against the noxious weed leafy spurge.
Aphthona czwalinae is a species of leaf beetle known as the black leafy spurge flea beetle. It is used as an agent of biological pest control against the noxious weed leafy spurge.
Diorhabda carinata is a species of leaf beetle known as the larger tamarisk beetle which feeds on tamarisk trees from Ukraine, eastern Turkey and Syria east to northwest China, Kyrgyzstan and Pakistan, extending as far south as southern Iran. It is used in North America as a biological pest control agent against saltcedar or tamarisk, an invasive species in arid and semi-arid ecosystems.
Aphthona lacertosa is a root-feeding flea beetle of the genus Aphthona. It is one of 5 Aphthona spp. that has been used in Alberta, Canada to control leafy spurge, an invasive plant that reduces pasture quality and degrades natural habitats.
Aphthona nigriscutis is a root-feeding flea beetle of the genus Aphthona. It is one of five Aphthona spp. that has been used in Alberta, Canada to control leafy spurge, an invasive plant that reduces pasture quality and degrades natural habitats. It, along with A. lacertosa, is one of only two biocontrol agents thought to be effective against leafy spurge.
Aphthona euphorbiae is a root-feeding flea beetle of the genus Aphthona. It is widely distributed throughout Europe, North Africa, the Caucasuses, Near East, Asia Minor, the southern part of West and Mid Siberia and Kazakhstan. In Latvia it has been reported as a pest of flax Linum.
Oberea erythrocephala, the leafy spurge stem boring beetle or red-headed leafy spurge stem borer is a species of longhorn beetle that is a biological control agent for leafy spurge. It is an effective killer of the pest but only works on certain strains of leafy spurge, namely the subgenus Esula of the genus Euphorbia. Because of this, the beetle is considered as secondary in leafy spurge control to five species of Aphthona flea beetle.
Asphaera is a genus of flea beetles in the family Chrysomelidae, containing some 130 species, found in North America, Central America, and the Neotropics.
Euphorbia virgata, commonly known as leafy spurge, wolf's milk leafy spurge, or wolf's milk is a species of spurge native to Europe and Asia, and introduced in North America, where it is an invasive species.
