Detection of the Early Sensitive Stage and Natural Resistance of Broad Bean (Vicia faba L.) Against Black Bean and Cowpea Aphids [PDF]

open access: yesInsects
Broad bean is one of the most important leguminous crops worldwide. However, its productivity is greatly affected by the infestation of Aphis fabae and Aphis craccivora (Hemiptera: Aphididae).

The Paraphyletic Origins of Genetic Resistance to Cabbage Stem Flea Beetle in <i>Brassica oleracea</i>. [PDF]

open access: yesPlant Environ Interact
ABSTRACT The cabbage stem flea beetle (CSFB) poses a growing threat to winter Brassica crops in Europe, yet the genetic basis of resistance remains poorly understood. To clarify the genetic architecture and evolutionary origins of resistance to CSFB adult feeding, we conducted a genome‐wide association study (GWAS) by combining high‐throughput pool ...

Characterization of Antibiosis and Antixenosis to the Soybean Aphid (Hemiptera: Aphididae) in Several Soybean Genotypes [PDF]

open access: yesJournal of Economic Entomology, 2006
The soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), is an introduced pest of soybean, Glycine max (L.) Merr., in North America, and it can reduce yields by 50%. Since 2000, when A. glycines was first detected in the United States, studies of this insect and possible control methods have been initiated.

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

open access: yesArch 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.

Characterization of Antixenosis in Soybean Genotypes to Bemisia tabaci (Hemiptera: Aleyrodidae) Biotype B [PDF]

open access: yesJournal of Economic Entomology, 2017
Bemisia tabaci biotype B (Gennadius) is one of the most important soybean pest worldwide. Herein, 15 soybean genotypes were evaluated, to characterize the occurrence of antixenosis to B. tabaci biotype B. Initially, a multiple-choice test with all genotypes was carried out, evaluating the settling and oviposition preference at 3 d after infestation ...

Antixenosis and Tolerance toDiabrotica speciosa(Coleoptera: Chrysomelidae) in Common Bean Cultivars [PDF]

open access: yesFlorida Entomologist, 2015
Abstract Diabrotica speciosa (Germar, 1824) (Coleoptera: Chrysomelidae) is a polyphagous insect pest that attacks several crops of agricultural importance including common beans (Phaseolus vulgaris L.; Fabales: Fabaceae). Diabrotica speciosa larvae feed on the plant root system whereas the adults are leaf defoliators. Diabrotica speciosa control relies

Aphid antixenosis in cotton is activated by the natural plant defence elicitor cis-jasmone

open access: yesPhytochemistry, 2012
Upon insect herbivory, plants can release blends of volatile organic compounds (VOCs) that modify herbivore and natural enemy behaviour. We have shown recently that cotton, Gossypium hirsutum, emits a blend of defence VOCs that repels the cotton aphid, Aphis gossypii, upon herbivory by this notorious crop pest, including (Z)-3-hexenyl acetate, (E)-4,8 ...

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

open access: yesJournal 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 ...

Trichomes and hydrocarbons associated with the tomato plant antixenosis to the leafminer [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2012
The objective of this work was to study the density of trichomes and hydrocarbons associated with the resistance by antixenosis of 42 subsamples of tomato plants from the Horticultural Germplasm Bank of the Universidade Federal de Viçosa (HGB-UFV) to Liriomyza trifolii. These subsamples were studied in addition to 'Santa Clara' cultivar, which was used

Resistance of Soybean Genotypes to Anticarsia gemmatalis (Lepidoptera: Erebidae): Antixenosis and Antibiosis Characterization

open access: yes, 2021
Injury by herbivores is a major biotic stress that limits soybean [Glycine max (L.) Merrill] crop production. Among the main soybean insect pests, Anticarsia gemmatalis Hübner is responsible for causing significant economic damage in soybean. The primary
