  • nicotianae and the aphid parasitoid Aphidius ervi as the experimental model, we explored whether root inoculation with an entomopathogenic fungus is compatible with parasitoid wasps for enhanced biocontrol of aphids. (rothamsted.ac.uk)
  • Inoculation of plants with A. muscarius did not affect parasitism rate nor parasitoid longevity, but significantly increased the speed of mummy formation in parasitized aphids on fungus-inoculated plants. (rothamsted.ac.uk)
  • We identified 14 phytophagous species (aphids), 39 predator species, 7 species of primary parasitoids, 12 species of secondary parasitoids, a species that acts both as secondary and tertiary parasitoid and 4 species of parasitoids of the predator species. (ub.ro)

  • The genus Brachycaudus includes species with all the types of life cycle (monoecy on woody plants, heteroecy, monoecy on herbs). (biomedcentral.com)
  • We used this genus to test hypotheses concerning the evolution of life cycles in aphids. (biomedcentral.com)
  • The transitions from monoecy on herbs towards heteroecy observed in this study go against a widely accepted evolutionary scenario: aphids in the genus Brachycaudus seem to be able to recapture their supposedly ancestral woody host. (biomedcentral.com)
  • We suggest that the evolutionary lability of life cycle may have driven speciation events in the Brachycaudus genus. (biomedcentral.com)
  • Members of the genus Potyvirus have virions which are flexuous filaments with no envelopes, are aphid-transmitted in a non-persistent, stylet-borne manner, mechanically transmitted, and may or may not be seed-transmitted. (apsnet.org)
  • Doing a decent job of aphid natural history and taxonomy will require substantially better botany skill and knowledge than I have gotten by with up until now. (aphidtrek.org)
  • This broad spectrum miticide/insecticide uses botanical oils (cottonseed, clove and garlic) to kill and control many varieties of mites, thrips and aphids. (arbico-organics.com)
  • We mentioned earlier that there are several aphid varieties. (safeandsanitaryhomes.org)
  • You'll find this article highly informative if you suspect having tree aphids. (safeandsanitaryhomes.org)
  • I suspect that the aphid lived in this situation because the shrubs provided good shelter from the wind. (aphidtrek.org)
  • Most aphid species complete their life cycle on the same set of host-plant species, but some (heteroecious species) alternate between different hosts, migrating from primary (woody) to secondary (herbaceous) host plants. (biomedcentral.com)
  • An arborist inspects and determines the extent of the aphids spread on trees and adopts a more suitable treatment procedure. (safeandsanitaryhomes.org)
  • Foraging trails radiating from a large nest may be up to 100 m or more usually orientated toward suitable aphid bearing trees. (antwiki.org)
  • Host alternation would have persisted in some cases due to developmental constraints preventing aphids from shifting their entire life cycle to herbaceous hosts (which are thought to be more favourable). (biomedcentral.com)
  • The first to third host plants reported as the new hosts for this aphid. (magiran.com)
  • Aphids are a superfamily of insects commonly known as plant lice . (biogrow.blog)
  • Due to the rapid reproduction of aphids, which is often faster than that of antagonist insects, the use of organic remedies is often necessary. (biogrow.blog)
  • Aphids are primarily soft-bodied pear-shaped insects with no specific color designation. (safeandsanitaryhomes.org)
  • Host alternation is found in about 10% of the 4500 described aphid species, the other 90% of aphids using the same group of host plants throughout their entire life cycle (these species are described as monoecious). (biomedcentral.com)
  • The most common types of aphids found on trees are woolly, green, and brown. (safeandsanitaryhomes.org)
  • Finding this species for the first time several years ago near my then home-town of Moses Lake was proof number umpteen that even when I think I've collected in an area long enough to have found all the aphid species, I am inevitably wrong. (aphidtrek.org)
  • Aphids on trees create many problems, including removing plant nutrients and damage. (safeandsanitaryhomes.org)
  • We discuss the impact of aphids on trees, symptoms, preventive measures, and several other aspects of aphid infestation. (safeandsanitaryhomes.org)
  • Ordinarily, the minimal activity of aphids on trees won't present much of a problem as trees can thrive. (safeandsanitaryhomes.org)
  • However, the increased activity of aphids on trees leads to various issues. (safeandsanitaryhomes.org)
  • While you have difficulty spotting aphids on trees, your best bet will be to look out for common symptoms. (safeandsanitaryhomes.org)
  • The most serious harm inflicted on trees by aphids is infection with the disease. (safeandsanitaryhomes.org)
  • Your trees may show signs of infection due to the prolonged fact and activity of aphids. (safeandsanitaryhomes.org)
  • Prey is taken somewhat unselectively from both trees and forest floor with any insect, arthropod or earthworm taken back as food to the nest although the main diet as with all species of this group is aphid honey dew. (antwiki.org)
  • Several shifts towards monoecy on herbaceous plants have subsequently occurred and resulted in the radiation of aphids. (biomedcentral.com)
