  2. Aphis craccivora - Wikipedia

    en.wikipedia.org/wiki/Aphis_craccivora

    A female aphid lives for 9 to 25 days and can produce from 25 to 125 young during its life. There may be up to twenty generations in the year. By November winged forms have developed and eggs are laid before winter sets in. [6] In warmer climates, parthenogenetic reproduction takes place throughout the year.

  3. Rhopalosiphum oxyacanthae - Wikipedia

    en.wikipedia.org/wiki/Rhopalosiphum_oxyacanthae

    These aphids follow the general life cycle of most other aphid species. [2] First generation females can lay around 100 eggs. Eggs of R. oxyacanthae will appear small, oval and shiny. The eggs are green but are difficult to differentiate between other species of aphid eggs. [2] Eggs are laid on branches and will typically hatch before other ...

  4. Melaphis rhois - Wikipedia

    en.wikipedia.org/wiki/Melaphis_rhois

    The galls occur when female aphids lay a single egg on the underside of the sumac leaf, inducing the leaf to form a sac over the egg. [5] According to Hebert et al, the eggs "give rise to a series of parthenogenetic generations, which remain within the gall. Winged females leave the gall in late summer and fly to moss, where they establish ...

  5. Aphidius - Wikipedia

    en.wikipedia.org/wiki/Aphidius

    Aphidius wasps are endoparasitoids of aphids. The female wasp lays eggs in an aphid. When the eggs hatch, the wasp larvae feed on the inside of the aphid. As the larvae mature, the hosts die and become slightly enlarged or mummified, often becoming tan or yellow. Complete metamorphosis occurs within the host.

  6. Aphid - Wikipedia

    en.wikipedia.org/wiki/Aphid

    Fungi are the main pathogens of aphids; Entomophthorales can quickly cut aphid numbers in nature. [134] Aphids may also be controlled by the release of natural enemies, in particular lady beetles and parasitoid wasps. However, since adult lady beetles tend to fly away within 48 hours after release, without laying eggs, repeated applications of ...

  7. Stegophylla essigi - Wikipedia

    en.wikipedia.org/wiki/Stegophylla_essigi

    Stegophylla essigi, also known as the California woolly oak aphid, is a species of North American aphid. [1] It had been found on many California oaks, including blue oaks , valley oaks , Oregon white oaks , coast live oaks , interior live oaks , California black oaks , and scrub oaks .

  8. Parthenogenesis - Wikipedia

    en.wikipedia.org/wiki/Parthenogenesis

    The production of female offspring by parthenogenesis is referred to as thelytoky (e.g., aphids) while the production of males by parthenogenesis is referred to as arrhenotoky (e.g., bees). When unfertilized eggs develop into both males and females, the phenomenon is called deuterotoky. [22]

  9. Acyrthosiphon pisum - Wikipedia

    en.wikipedia.org/wiki/Acyrthosiphon_pisum

    The aphid genome is 464MB with aphid-specific orphan genes making up 20% of the genome and gene duplication present in more than 2000 gene families. [ 23 ] [ 34 ] These orphan genes and gene duplications are likely associated with the “metabolic, structural and developmental” components of the endosymbiotic relationship. [ 34 ]
