Aphis oestlundi is a species of aphid in the family Aphididae. [1] [2] [3] [4]
Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, although individuals within a species can vary widely in colour. The group includes the fluffy white woolly aphids. A typical life cycle involves flightless females giving living birth to female nymphs without the involvement of males. Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly. Winged females may develop later in the season, allowing the insects to colonise new plants. In temperate regions, a phase of sexual reproduction occurs in the autumn, with the insects often overwintering as eggs.
The Aphididae are a very large insect family in the aphid superfamily (Aphidoidea), of the order Hemiptera. Several thousand species are placed in this family, many of which are well known for being serious plant pests. They are also the family of insects containing most plant virus vectors with the green peach aphid being one of the most prevalent and indiscriminate carriers.
The little black ant is a species of ant native to North America. It is a shiny black color, the workers about 1 to 2 mm long and the queens 4 to 5 mm long. It is a monomorphic species, with only one caste of worker, and polygyne, meaning a nest may have more than one queen. A colony is usually moderately sized with only a few thousand workers.
Toxoptera citricida is a species of aphid known by the common names brown citrus aphid, black citrus aphid, and oriental citrus aphid. It is a pest of citrus and vector for the pathogenic plant virus citrus tristeza virus. The aphid spread the virus through citrus groves in Brazil and Venezuela in the 1970s, leading to the near destruction of the citrus industry there. This aphid was first discovered in Florida in 1995.
The soybean aphid is an insect pest of soybean that is exotic to North America. The soybean aphid is native to Asia. It has been described as a common pest of soybeans in China and as an occasional pest of soybeans in Indonesia, Japan, Korea, Malaysia, the Philippines, and Thailand. The soybean aphid was first documented in North America in Wisconsin in July 2000. Ragsdale et al. (2004) noted that the soybean aphid probably arrived in North America earlier than 2000, but remained undetected for a period of time. Venette and Ragsdale (2004) suggested that Japan probably served as the point of origin for the soybean aphid's North American invasion. By 2003, the soybean aphid had been documented in Delaware, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Mississippi, Missouri, Nebraska, New York, North Dakota, Ohio, Pennsylvania, South Dakota, Virginia, West Virginia, and Wisconsin. Together, these states accounted for 89% of the 63,600,000 acres (257,000 km2) of soybean planted in the United States in 2007.
Aphis is a genus of insects in the family Aphididae containing at least 600 species of aphids. It includes many notorious agricultural pests, such as the soybean aphid Aphis glycines. Many species of Aphis, such as A. coreopsidis and A. fabae, are myrmecophiles, forming close associations with ants.
The black bean aphid is a small black insect in the genus Aphis, with a broad, soft body, a member of the order Hemiptera. Other common names include blackfly, bean aphid, and beet leaf aphid. In the warmer months of the year, it is found in large numbers on the undersides of leaves and on the growing tips of host plants, including various agricultural crops and many wild and ornamental plants. Both winged and wingless forms exist, and at this time of year, they are all females. They suck sap from stems and leaves and cause distortion of the shoots, stunted plants, reduced yield, and spoiled crops. This aphid also acts as a vector for viruses that cause plant disease, and the honeydew it secretes may encourage the growth of sooty mould. It breeds profusely by live birth, but its numbers are kept in check, especially in the later part of the summer, by various predatory and parasitic insects. Ants feed on the honeydew it produces, and take active steps to remove the aphid's enemies. It is a widely distributed pest of agricultural crops and can be controlled by chemical or biological means. In the autumn, winged forms move to different host plants, where both males and females are produced. These mate and the females lay eggs which overwinter.
Aphis affinis is an aphid of the family Aphididae. The species was described by Giacomo del Guercio in 1911. It is found in southern Europe, the Middle East and the Indian subcontinent. Ladybird predator species of A. affinis include Brumoides suturalis, Cheilomenes sexmaculata and Coccinella transversalis.
Aphis craccivora, variously known as the cowpea aphid, groundnut aphid or black legume aphid, is a true bug in the family Aphididae. Originally of probable Palearctic origin, it is now an invasive species of cosmopolitan distribution.
Aphis nerii is an aphid of the family Aphididae. Its common names include oleander aphid, milkweed aphid, sweet pepper aphid, and nerium aphid.
Aphis spiraecola is a species of aphid described in 1914 by Edith Marion Patch. Its common names include green citrus aphid, Spirea aphid, and apple aphid. It is a relatively small member of the Aphid species, and is distributed worldwide, most abundant in the United States. A. spiraecola belongs to the eukarya domain, metazoa kingdom, arthropoda phylum, and uniramia subphylum. Its class is insecta, order is hemiptera and suborder is sternorrhyncha. It belongs to the family aphididae, genus is aphis. It has a diploid chromosome number of 2n=8.
Aphis pomi, commonly known as the apple aphid, or the green apple aphid, is a true bug in the family Aphididae. It is found on young growth of apple trees and on other members of the rose family where it feeds by sucking sap. Reproduction is mainly by parthenogenesis, in which unmated females give birth to live young.
Aphis genistae is an aphid of the family Aphididae.
Cerataphis orchidearum, the fringed orchid aphid, is a species of aphid in the family Aphididae. It is found in Europe.
Cerataphis is a genus of witch hazel and palm aphids in the family Aphididae. There are about 10 described species in Cerataphis.
Uroleucon pseudambrosiae is a species of aphid in the family Aphididae.
