	Aphelinus Mali ''Aphelinus mali'' is a parasitoid wasp that exploits the woolly apple aphid (''Eriosoma lanigerum''), a pest of apple trees. It is native to the northeastern United States but has been introduced to other parts of the world as a biological pest control agent. Description The adult ''A. mali'' is a tiny black wasp slightly smaller than its woolly aphid host. Its transparent membranous wings are longer than its abdomen and fold flat along its back. Although it can fly, it prefers to walk and jump, and often conceals itself under leaves. The larvae and pupae remain hidden inside the host; the larvae are yellow with red eyes, and the pupae are black. Distribution This parasitoid is a parasite of aphids, particularly woolly aphids and is native to the northeastern parts of the United States. It was introduced in 1928 to the orchards of the Pacific Northwest in the region of Hood River and spread naturally. It has since been introduced to many other parts of the world with the aim of ...

	Johan Wilhelm Dalman Johan Wilhelm Dalman (November 4, 1787 in Hinseberg, Västmanland – July 11, 1828 in Stockholm) was a Swedish physician and a naturalist. He first studied at Christiansfeld in Schleswig-Holstein then at the University of Lund and the University of Uppsala. He was mainly interested in entomology and botany. He received his degree in 1816 then his doctorate in 1817 from the University of Uppsala. Dalman became librarian of the Royal Swedish Academy of Sciences, a member of the Academy in 1821, then director of the zoological garden, then demonstrator in botany at the Karolinska Institutet of Stockholm. Dalman's main interest lay in entomology and botany, but he also became involved in the systematics and taxonomy of trilobites. In 1771 Johann Ernst Immanuel Walch (1725-1778) first used the term trilobite. Researchers had tried to link trilobites to extant groups such as chitons and various arthropods.

	Diuraphis Noxia The Russian wheat aphid (''Diuraphis noxia'') is an aphid that can cause significant losses in cereal crops. The species was introduced to the United States in 1986 and is considered an invasive species there. This aphid is pale green and up to 2 mm long. Cornicles are very short, rounded, and appear to be lacking. There is an appendage above the cauda giving the aphid the appearance of having two tails. The saliva of this aphid is toxic to the plant and causes whitish striping on cereal leaves. Feeding by this aphid will also cause the flag leaf to turn white and curl around the head causing incomplete head emergence. Its host plants are cereal grain crops including wheat and barley and to a lesser extent, wild grasses such as wheatgrasses, brome-grasses, ryegrasses and anything in the grass family. The Russian wheat aphid is native to southwestern parts of Asia. It was introduced to many countries in Europe and Africa. It was first found in the U.S. in 1986 in Texas. The ...
