Aphthona is a genus of beetle, in the leaf beetle family Chrysomelidae, native to Europe and Asia. More specifically, Aphthona are flea beetles, meaning they have enlarged hind legs for jumping away from potential danger. There are some 300 species known worldwide. [2]
This flea beetle genus is important because of the usefulness of some species in controlling leafy spurge, a major invasive weed in parts of western North America. Several Aphthona species have been taken from Europe and introduced into localized areas of the United States and Canada, and some success against the weed is being seen. [3] [4] The six species used for this purpose include A. abdominalis, A. cyparissiae, A. czwalinae, A. flava, A. nigriscutis, and A. lacertosa, though A. abdominalis apparently never established a viable population and was never introduced in Canada. [5] [6] [7]
Control is generally thought to be effective, but results vary from site to site, which has been attributed to soilborne pathogens, phenology of spring, soil texture, and leafy spurge density. Control is less effective in sandy soils. [8] Control may not be reliably observed and measured for 10 years or more.
Euphorbia is a very large and diverse genus of flowering plants, commonly called spurge, in the family Euphorbiaceae.
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 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.
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 carinulata is a species of leaf beetle known as the northern tamarisk beetle, which feeds on tamarisk trees from southern Russia and Iran to Mongolia and western China. This beetle is used in North America as a biological pest control agent against saltcedar or tamarisk, an invasive species in arid and semiarid 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. It is widely distributed throughout Europe, North Africa, the Caucasus, 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.
Chamaesphecia crassicornis is a moth of the family Sesiidae. It is found in south-eastern Austria, southern Slovakia, Hungary, Serbia, Romania, Bulgaria, southern Russia, Kazakhstan and Kyrgyzstan. It is rare in central Europe. It has been released in North America for the biological control of leafy spurge.
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.
Calligrapha is a large genus of American Chrysomelinae, with over 100 species occurring from North America through Central America.
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.
Cacoscelis is a genus of flea beetles in the family Chrysomelidae, found in southern North America, Central America, and South America.
