Antixenosis phloem‐based resistance to aphids: is it the rule?

open access: yesEcological Entomology, 2010
1. The concept of plant defence syndrome states that plant species growing in similar biotic or abiotic constraints should have convergent defensive traits. This article is a first step to test the prediction of this concept, by conducting experiments on wild Solanum species (or accessions ...

Antibiosis and antixenosis to Rhopalosiphum padi among triticale accessions

Euphytica, 2005
Tests for antibiosis and antixenosis resistance to Rhopalosiphum padi L., the bird cherry-oat aphid, were conducted among four wheat (Triticum aestivum L.) and eight triticale (XTriticosecale Wittmack) accessions. Tests for antibiosis included measuring R. padi-population growth over 13 days, number of days to reproduction of individual R.

Field tests for antixenosis and tolerance of cocoa towards mirids [PDF]

open access: yes, 2004
Field tests for antixenosis (feeding non-preference) and tolerance of cocoa trees to mirid damage were conducted as part of the CFC/ICCO/IPGRI Project, in the budwood garden of IRAD Nkolbisson Station. Antixenosis was assessed by counting the number of mirid bites on the flush after 24 hours, while assessment of tolerance was based on regular ...

Resistance of Collard Green Genotypes to Bemisia tabaci Biotype B: Characterization of Antixenosis

open access: yesNeotropical Entomology, 2018
Bemisia tabaci (Genn.) biotype B (Hemiptera: Aleyrodidae) is an important pest of vegetable crops, including collard greens Brassica oleracea var. acephala (Brassicaceae). The use of resistant genotypes is an interesting option to reduce insect populations and can be used as an important tool for integrated pest management (IPM).

Evaluation of a choice-test method to assess resistance of melon to Aphis gossypii Glover (Homoptera: Aphididae) by comparison with conventional antibiosis and antixenosis trials

open access: yesApplied Entomology and Zoology, 2003
The Vat gene of melon confers resistance to Aphis gossypii through both antixenotic and antibiotic mechanisms. This article reports several experiments carried out to detect this gene in melon lines from a melon breeding program.

Wild Solanum Resistance to Aphids: Antixenosis or Antibiosis?

Journal of Economic Entomology, 2008
The type (antixenosis or antibiosis) of resistance against the aphids Myzus persicae (Sulzer) and Macrosiphum euphorbiae (Thomas) was characterized for the wild tuber-bearing potatoes, Solanum chomatophilum Bitter and Solanum stoloniferum Schltdl. & Bouché through behavioral (olfactometry and electrical penetration graph) and physiological studies.

Mechanisms of Antixenosis and Antibiosis of Ash Against Emerald Ash Borer

open access: yes, 2016
Emerald ash borer (EAB), Agrilus planipennis (Coleoptera: Buprestidae), is an invasive forest pest causing widespread mortality of ash (Fraxinus spp.) in North America. Host resistance research and the development of resistant hosts offers a promising strategy for the long-term conservation of ash and management of EAB. Manchurian ash (F.
