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,

Antixenosis and Tolerance of Rice Genotypes Against Brown Planthopper

Rice Science, 2016
Nine genotypes were evaluated under greenhouse conditions for antixenosis and tolerance against brown planthopper (BPH, Nilaparvata lugens Stål). In antixenosis studies, proportion of insects settled on a test genotype in relation to the susceptible ...

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

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 ...

Rapid screening for resistance to Sitobion avenae (F.) and Rhopalosiphum padi (L.) in winter wheat seedlings and selection of efficient assessment methods. [PDF]

Pest Manag Sci
Aphid resistance screening on wheat was carried out at three stages: host selection, population growth and feeding activity, where stylet derailment and phloem feeding were linked to aphid resistance. Abstract BACKGROUND Sitobion avenae (F.) and Rhopalosiphum padi (L.) are harmful pests of wheat [Triticum aestivum (L.)].

Response of the tomato leaf miner Phthorimaea absoluta to wild and domesticated tomato genotypes. [PDF]

Pest Manag Sci
We evaluated oviposition and larval performance of P. absoluta on 19 tomato genotypes as an element of integrated pest management. Two wild tomatoes and a domesticated one showed resistance against the pest. Abstract BACKGROUND Phthorimaea absoluta, a highly destructive invasive pest, poses a significant threat to tomato production globally.

Influence of Soybean Cultivar Resistance on the Foraging Behavior of Encarsia sp. Against Bemisia tabaci MEAM1. [PDF]

Arch Insect Biochem Physiol
The volatiles emitted by tested soybean cultivars did not significantly affect the attraction of Encarsia sp. parasitoid in Y‐shaped olfactometer. The cultivar Bônus may exert a more attractive effect and diversified foraging behavior compared to whitefly‐resistant M8808 cultivar.

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.
