Characterisation of aphid antixenosis in aphid-resistant ancestor wheat, Triticum monococcum. [PDF]

Pest Manag Sci
A blend of 21 volatile organic compounds (VOCs) released from Sitobion avenae‐infested Triticum monococcum accessions MDR045 and MDR049 was identified and shown to induce antixenosis towards alate S. avenae. Abstract BACKGROUND Due to the increasing presence of insecticide resistance across cereal aphid populations, new aphid management strategies ...

Antixenosis of bean genotypes to Chrysodeixis includens (Lepidoptera: Noctuidae) [PDF]

Pesquisa Agropecuária Brasileira, 2015
The objective of this work was to evaluate bean genotypes for resistance to soybean looper (Chrysodeixis includens). Initially, free-choice tests were carried out with 59 genotypes, divided into three groups according to leaf color intensity (dark green,

Resistance mechanisms in collard green genotypes to Plutella xylostella: role of physical and morphological traits. [PDF]

Pest Manag Sci
Resistance to Plutella xylostella in collard greens is mediated by antixenosis and antibiosis, associated with traits such as leaf wax, hardness, and color. Genotypes showed strong resistance potential, supporting their use in breeding and integrated pest management strategies. Abstract BACKGROUND The diamondback moth, Plutella xylostella (Lepidoptera:

Metabolite-based resistance in wheat varieties to aphid virus vectors: progress and future opportunities. [PDF]

Pest Manag Sci
Sitobion avenae and Rhopalosiphum padi are major pests on wheat. Natural product‐based aphid resistance holds promise for the sustainable control of these pests. The current literature is discussed, highlighting knowledge gaps and challenges that need addressing. Abstract Cereal aphids, Sitobion avenae and Rhopalosiphum padi, cause severe yield loss in

Loss of flavonol 3-O-glucosyltransferase activity confers soybean resistance to leaf-chewing insects. [PDF]

Plant J
Significance Statement The loss of flavonol 3‐O‐glucosyltransferase activity in soybean reduces feeding damage from defoliating insects and is accompanied by a concomitant increase in proanthocyanidins (red arrowhead). Unraveling the biochemical and genetic basis of soybean resistance to leaf‐chewing insects facilitates the development of new ...

Characterizing Resistance to Soybean Aphid (Hemiptera: Aphididae): Antibiosis and Antixenosis Assessment [PDF]

Journal of Economic Entomology, 2021
Abstract Host-plant resistance (HPR) remains a vital tool to manage soybean aphid (Aphis glycines Matsumura), a major pest of soybean in Midwestern United States and southern Canada. HPR can be overcome by virulent biotypes of A. glycines; thus, in order to increase the durability of resistant cultivars, HPR needs to be deployed ...

Protocol for assessing soybean antixenosis toHeliothis virescens

Entomologia Experimentalis et Applicata, 2020
AbstractLarvae ofHeliothis virescens(Fabricius) (Lepidoptera: Noctuidae) often infest soybean crops,Glycine max(L.) (Fabaceae), causing significant yield losses in important soybean‐producing regions. The use of soybean varieties resistant to lepidopteran larvae is a major approach in soybean integrated pest management.

Antixenosis to Chrysodeixis includens (Lepidoptera: Noctuidae) among soybean genotypes [PDF]

Bragantia, 2017
ABSTRACT The soybean looper Chrysodeixis includens is one of the main defoliating pests of soybean cultures in Brazil. This work aimed to evaluate the effect of offering different soybean genotypes to this insect to verify the occurrence of antixenosis. In a greenhouse, assays were carried out to determine the attractiveness of C.

Chinch Bug-Resistant Buffalograss: An Investigation of Tolerance, Antixenosis, and Antibiosis [PDF]

Journal of Economic Entomology, 2003
Choice and no-choice studies were conducted to determine the categories (antibiosis, antixenosis, and tolerance) of resistance of four buffalograsses (NE91-118, 'Bonnie Brae', 'Cody', and 'Tatanka') previously identified as resistant to the western chinch bug, Blissus occiduus Barber.
