They are the family of insects containing most plant virus vectors (around 200 known) with the green peach aphid (Myzus persicae) being one of the most prevalent and indiscriminate carriers. (wikipedia.org)

Myzus1
We found that effectors from the oomycete pathogen, Phytophthora capsici, and the major aphid pest, Myzus persicae target the host immune regulator SIZ1, an E3 SUMO ligase. (bvsalud.org)
Hemiptera3
The Aphididae are a very large insect family in the aphid superfamily (Aphidoidea), of the order Hemiptera. (wikipedia.org)
Acyrthosiphon kondoi, the blue alfalfa aphid, also known as bluegreen aphid, is an aphid in the superfamily Aphidoidea in the order Hemiptera.It is a true bug and sucks sap from leguminous plants, particularly alfalfa (known as lucerne in most countries outside North America). (findmybuilder.com)
Aphids (Hemiptera: Aphidoidea) are among the most detrimental insects for agricultural plants, and their management is a great challenge in agronomical research. (bvsalud.org)
Acyrthosiphon2
The pea aphid, Acyrthosiphon pisum, is a paradigmatic photoperiodic species with an annual life cycle tightly coupled to the seasonal changes in day length. (bvsalud.org)
BCRs were initially identified in the pea aphid Acyrthosiphon pisum. (bvsalud.org)
Gossypii2
Aphis gossypii, described here, is common in Pacific island countries. (findmybuilder.com)
Members of the Aphididae are soft-bodied, pear-shaped insects called aphids, as are other members of the superfamily Aphidoidea. (wikipedia.org)
19921
In 1992, aphid populations that exceeded 50/leaf for 3 weeks, and 100/leaf for 2 weeks significantly reduced cotton plant height. (findmybuilder.com)
Pear-shaped1
Aphids are small, pear-shaped, soft-bodied insects. (findmybuilder.com)
Soft-bodied2
The larva is a voracious predator attacking soft-bodied insects such as aphids and caterpillars of like or smaller size. (findmybuilder.com)
Aphids are soft-bodied, sucking insects that are sometimes called plant lice. (findmybuilder.com)
Pest1
Many pest aphids, however, do not overwinter as an egg but as nymphs or adults and others as both eggs and active stages (see Williams and Dixon 2007). (wikipedia.org)
Insect2
They are small disulfide bond-rich proteins expressed exclusively in aphid bacteriocytes, the insect cells that host intracellular symbiotic bacteria. (bvsalud.org)
Here, we show that one of the A. pisum BCRs, BCR4, displays prominent insecticidal activity against the pea aphid, impairing insect survival and nymphal growth, providing evidence for its potential use as a new biopesticide. (bvsalud.org)
Species4
Aphids originated in the late Cretaceous about 100 million years ago (Mya), but the Aphidinae which comprises about half of the 4700 described species and genera of aphids alive today come from their most recent radiation which occurred in the late Tertiary less than 10 Mya. (wikipedia.org)
Most aphid species can reproduce both asexually and sexually, with several parthenogenetic generations between each period of sexual reproduction. (wikipedia.org)
The differences in within-year population dynamics of aphids are due to differences in the effect these seasonal fluctuations in host plant quality have on the per capita rate of increase and intraspecific competition in each species. (wikipedia.org)
Aphids do best when amino acids are actively translocated in the phloem. (wikipedia.org)
Seasonal3
The within-year dynamics of aphids are largely determined by seasonal changes in host quality. (wikipedia.org)
A newly generated aphid-specific PDF antibody stained four neurons in each hemisphere of the aphid brain that co-express the clock protein Period and have projections to the pars lateralis that are highly plastic and change their appearance in a daily and seasonal manner, resembling those of the fruit fly PDF neurons. (bvsalud.org)
Since ILP has been previously shown to be crucial for seasonal adaptations and CRY might serve as a circadian photoreceptor vital for measuring day length, our results suggest that PDF plays a critical role in aphid seasonal timing. (bvsalud.org)
Survival1
The survival of the eggs and/or overwintering aphids determines the numbers of aphids present the following spring. (wikipedia.org)
Suck1
The larva can suck the life juice from an aphid in 90 seconds and can eat 100 aphids or more in a week. (findmybuilder.com)
Small1
All aphids have very small eyes, sucking mouthparts in the form of a relatively long, segmented rostrum, and fairly long antennae. (wikipedia.org)
Host2
This annual cycle, consisting of two short periods when the host plant is very favourable and a long intervening period when it is less favourable, is well documented for tree dwelling aphids. (wikipedia.org)
Thus on trees the leaves are most suitable for aphids in spring and autumn. (wikipedia.org)
To sample for potato aphids, remove leaves from the terminal parts of 35 plants and count the number of aphids. (findmybuilder.com)
Plants1
In general the aphid carrying capacity of annual crop plants tends to increase with the season until the plants mature after which it tends to decrease very rapidly. (wikipedia.org)
Plant1
Aphids excrete a sugary liquid called honeydew, because the plant sap from which they feed contains excess carbohydrates relative to its low protein content. (wikipedia.org)
Liquid1
Chemical control: Aphids can be controlled by spraying soap-water @ 25ml liquid detergent per liter of water. (findmybuilder.com)
Insects3
They are the family of insects containing most plant virus vectors (around 200 known) with the green peach aphid (Myzus persicae) being one of the most prevalent and indiscriminate carriers. (wikipedia.org)
Members of the Aphididae are soft-bodied, pear-shaped insects called aphids, as are other members of the superfamily Aphidoidea. (wikipedia.org)
Here, we use abundance times series for a diverse group of herbivorous insects, aphids, to search for trai. (researchgate.net)
Population dynamics1
The differences in within-year population dynamics of aphids are due to differences in the effect these seasonal fluctuations in host plant quality have on the per capita rate of increase and intraspecific competition in each species. (wikipedia.org)
Pest2
Many pest aphids, however, do not overwinter as an egg but as nymphs or adults and others as both eggs and active stages (see Williams and Dixon 2007). (wikipedia.org)
Soybean aphid (Aphis glycines Matsumura) is a pest of soybean in the northern Midwest whose migratory patterns have been difficult to quantify. (researchgate.net)
Complex1
Thus, aphids show very complex and rapidly changing within-year dynamics, with each clone going through several generations during the vegetative season and being made up of many individuals, which can be widely scattered in space. (wikipedia.org)
Virus1
Thrips-infesting soybeans were considered of minor economic importance, but recent evidence of their ability to transmit a newly identified soybean virus, Soybean vein necrosis virus (SVNV), has raised their profile as pests. (researchgate.net)
