[22], The phylogenetic tree, based on Papasotiropoulos 2013 and Kim 2011, with additions from Ortiz-Rivas and Martinez-Torres 2009, shows the internal phylogeny of the Aphididae. The young emerge from the mother soon after hatching. The group includes the fluffy white woolly aphids. For example, one large, heavily infested rose bush may take two applications of 1500 beetles each. However, since adult lady beetles tend to fly away within 48 hours after release, without laying eggs, repeated applications of large numbers of lady beetles are needed to be effective.

Thus, a female's diet can affect the body size and birth rate of more than two generations (daughters and granddaughters). Aphids may occupy the undersides of leaves where spray misses them, while systemic insecticides do not move satisfactorily into flower petals. As fall approaches, the soybean plants begin to senesce from the bottom upwards. Earwigs have two pairs of leather wings. [112][126][127], Aphid populations can be sampled using yellow-pan or Moericke traps. The eggs are laid in batches, each female laying several hundred. On this it may alternate between sexual and asexual generations (holocyclic) or alternatively, all young may be produced by parthenogenesis, eggs never being laid (anholocyclic). Here they mate and overwinter as eggs. Natural enemies include predatory ladybugs, hoverfly larvae, parasitic wasps, aphid midge larvae, crab spiders, lacewing larvae, and entomopathogenic fungi. [47] Using their carotenoids, aphids may well be able to absorb solar energy and convert it to a form that their cells can use, ATP. [38], Xylem sap consumption may be related to osmoregulation. [75] The metabolites from endosymbionts are also excreted in honeydew. It was felt that the excess honeydew would nourish soil micro-organisms, including nitrogen fixers. [109], Aphids are abundant and widespread, and serve as hosts to a large number of parasitoids, many of them being very small (c. 0.1 inches (2.5 mm) long) parasitoid wasps. For example, some species of cabbage aphids (like Brevicoryne brassicae) can produce up to 41 generations of females in a season. [66] Some species such as Aphis fabae (black bean aphid), Metopolophium dirhodum (rose-grain aphid), Myzus persicae (peach-potato aphid), and Rhopalosiphum padi (bird cherry-oat aphid) are serious pests. [19] Phylloxera (Daktulosphaira vitifoliae) are insects which caused the Great French Wine Blight that devastated European viticulture in the 19th century. [124], Dispersal can be by walking or flight, appetitive dispersal, or by migration. [88], Aphids are eaten by many bird and insect predators. Among ladybirds, Myzia oblongoguttata is a dietary specialist which only feeds on conifer aphids, whereas Adalia bipunctata and Coccinella septempunctata are generalists, feeding on large numbers of species. [10] The total number of species was small, but increased considerably with the appearance of the angiosperms 160 million years ago, as this allowed aphids to specialise, the speciation of aphids going hand-in-hand with the diversification of flowering plants. [11] It has been hypothesized that the ancestors of the Adelgidae lived on conifers while those of the Aphididae fed on the sap of Podocarpaceae or Araucariaceae that survived extinctions in the late Cretaceous.
