However, there are differences between these sexual social insects and the clonal aphids, which are all descended from a single female parthenogenetically and share an identical genome. About fifty species of aphid, scattered among the closely related, host-alternating lineages Eriosomatinae and Hormaphidinae, have some type of defensive morph ...
The Aphididae are a very large insect family in the aphid superfamily , of the order Hemiptera. These insects suck the sap from plant leaves. These insects suck the sap from plant leaves. Several thousand species are placed in this family , many of which are considered plant/crop pests.
Aphis is a genus of insects in the family Aphididae containing at least 600 species of aphids. [1] 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 .
Adult winged aphids have a black head and thorax, and a yellowish green abdomen with a large dark dorsal patch. They measure approximately 1.8 to 2.1 millimetres (0.071 to 0.083 in) in length. [3] The wingless adult aphids are yellowish or greenish in colour, with the possibility of medial and lateral green strips being present.
Acyrthosiphon pisum, commonly known as the pea aphid (and colloquially known as the green dolphin, [1] [2] pea louse, and clover louse [3]), is a sap-sucking insect in the family Aphididae. It feeds on several species of legumes (plant family Fabaceae ) worldwide, including forage crops, such as pea , clover , alfalfa , and broad bean , [ 4 ...
Female aphids reproduce by parthenogenesis, males have never been observed in the wild but have been produced under laboratory conditions. [10] Females may be wingless or winged ( alate ), the production of the alate form occurs a higher rate in those regions where it is necessary for oleander aphid to migrate each year on to temporary hosts.
Aphidinae is an aphid subfamily in the family Aphididae.. Many species of aphids spread potyviruses and most are from the subfamily Aphidinae (genera Macrosiphum and Myzus).Most have alternative hosts, the primary host plant is usually a tree, and the secondary one is herbaceous.
The small, bright orange, slug-like larvae inject a toxin into aphids' leg joints to paralyze them and then suck out the aphid body contents through a hole bitten in the thorax. [3] Larvae can consume aphids much larger than themselves and may kill many more aphids than they eat when aphid populations are high. [ 2 ]
