Laricobius Rubidus
''Laricobius rubidus'' is a species of tooth-necked fungus beetle in the family Derodontidae. It is found in North America. Studies are ongoing to determine the rate of hybridization between ''L. rubidus'', which feeds on pine bark adelgid, and its native congener, '' Laricobius nigrinus'', which is being studied as a biological control agent for the hemlock woolly adelgid The hemlock woolly adelgid (; ''Adelges tsugae''), or HWA, is an insect of the order Hemiptera (true bugs) native to East Asia. It feeds by sucking sap from hemlock and spruce trees (''Tsuga'' spp.; ''Picea'' spp.). In its native range, HWA ....

John Lawrence LeConte
John Lawrence LeConte (May 13, 1825 – November 15, 1883) was an American entomologist of the 19th century, responsible for naming and describing approximately half of the insect taxa known in the United States during his lifetime,Bird Name Biographies - URL retrieved September 14, 2006 including some 5,000 of beetles. He was recognized as the foremost authority on North American s during his lifetime, and has been described as "the father of American beetle study".Evans, Arthur V., and James N. Hogue. 2004.

Tooth-necked Fungus Beetle
Derodontidae is a family of beetles, in its own superfamily, Derodontoidea, sometimes known as the tooth-necked fungus beetles. Beetles of this family are small, between 2 and 6 mm in length, typically with spiny margins on their pronotum (part of the thorax) that give them their name, though the genus ''Laricobius'' lacks these spines. Unusual among beetles, they have two ocelli on the top of their heads. They are related to the Bostrichoidea, which includes the death watch beetles, skin beetles, powder-post beetles and other subgroups. Some species feed on slime molds, but the larvae and adults of the genus ''Laricobius'' are predators of woolly adelgids which attack conifers, and species of this genus are used as biological control agents in the United States for control of balsam woolly adelgid and hemlock woolly adelgid. There are 42 species in 4 genera and 3 subfamilies. The family includes: *Subfamily Derodontinae **Genus ''Derodontus'' (11 species) *Subfamily Laric ...

Congener (biology)
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laricobius Nigrinus
''Laricobius nigrinus'' is a species of tooth-necked fungus beetle in the family Derodontidae. It is native to western North America, and it is being studied as a biological control agent for the hemlock woolly adelgid. It was first released in 2003 and continues to be reared and released across the Northeast to control infestations. Taxonomy ''Laricobius nigrinus'' was first described by Kenneth Fender in 1945 from specimens collected in Oregon. ''Laricobius'' is one of four genera in Derodontidae. The genus has a Holarctic distribution, with most species native to Asia. Description Adult beetles have a black body, clubbed antennae with eleven segments, and two ocelli. Their palps, antennae, and tarsi are dark brown to red. The head is partially visible from above. They are usually 2.3-2.9 mm long, with no significant sex differences in size. The species can be distinguished from other black ''Laricobius'' by its toothed pronotal margin. Its eggs are yellow and oblong ...

Biological Control
Biological control or biocontrol is a method of controlling pests, such as insects, mites, weeds, and plant diseases, using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs. There are three basic strategies for biological pest control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to maintain natural enemies through regular reestablishment. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors. Biological control agents of plant diseases are most often referred to as antagonists. Biologic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemlock Woolly Adelgid
The hemlock woolly adelgid (; ''Adelges tsugae''), or HWA, is an insect of the order Hemiptera (true bugs) native to East Asia. It feeds by sucking sap from hemlock and spruce trees (''Tsuga'' spp.; ''Picea'' spp.). In its native range, HWA is not a serious pest because populations are managed by natural predators and parasitoids and by host resistance. In eastern North America it is a destructive pest that threatens the eastern hemlock (''Tsuga canadensis'') and the Carolina hemlock (''Tsuga caroliniana''). HWA is also found in western North America, where it has likely been present for thousands of years. In western North America, it primarily attacks western hemlock ''Tsuga heterophylla'' and has only caused minor damage due to natural predators and host resistance. Accidentally introduced to North America from Japan, HWA was first found in the eastern United States near Richmond, Virginia, in 1951. The pest is now found from northern Georgia to coastal Maine and southwest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
