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.

Screening of soybean genotypes for antixenosis against Spodoptera litura

Journal of Oilseeds Research, 2020
Among 95 soybean genotypes screened against Spodoptera litura, 2 genotypes viz., Hara Soya and G5P22exhibited strong antixenosis, 11 genotypes exhibited moderate antixenosis. Whereas, 40 genotypes and 42 genotypes expressed slight antixenosis and preference host respectively.

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

Ecological 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 ...

Mechanisms of resistance in cotton to whitefly (Bemisia tabaci): antixenosis

Phytoparasitica, 2011
Screenhouse experiments were conducted under free-choice conditions to determine the mechanism of resistance operating in cotton against whitefly, Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae). Twelve cotton genotypes belonging to Gossypium hirsutum and G. arboreum were assessed for oviposition preference by whitefly.

Antixenosis and Antibiosis of Common Beans to Thrips palmi Karny (Thysanoptera: Thripidae)

Journal of Economic Entomology, 2003
Antixenosis and antibiosis in the resistance of common beans (Phaseolus vulgaris L.) to the melon thrips, Thrips palmi Karny, were investigated under laboratory and field conditions. Experiments were conducted for four moderately resistant genotypes ('Brunca', BH-130, EMP 486, and FEB 115) in comparison with one susceptible genotype (APN 18).

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.

Techniques for Determining Mechanisms of Resistance: Antixenosis for Feeding

2019
Entomologists have designed several experimental setup to measure feeding responses of insects to host–plants. One method each for chewing and sucking pests has been described in this chapter. The experimental techniques should be easy to execute, repeatable, and precise.
