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:

Characterization of antixenosis toDichelops melacanthus(Hemiptera: Pentatomidae) in soybean genotypes [PDF]

International Journal of Pest Management, 2016
ABSTRACTSoybeans are of great importance in the world agricultural landscape, and their productive potential is significantly reduced by attacks from insect pests. Factors such as the expansion of national agricultural regions, together with no-tillage management and “off-season” maize cultivation, have favored the increase of secondary species such as

Aphid Antixenosis Mediated by Volatiles in Cereals

Acta Agriculturae Scandinavica - Section B Soil and Plant Science, 1996
Abstract Experimental results indicate the existence of an inducible system that can temporarily help cereal plants to defend themselves against cereal aphids. The induction is released by volatiles emitted when aphids attack a neighbour plant individual. Similar effects are obtained with mildew attacked plants.

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.

QTL mapping of antixenosis resistance to common cutworm (Spodoptera litura Fabricius) in wild soybean (Glycine soja). [PDF]

PLoS ONE, 2017
The common cutworm (CCW; Spodoptera litura Fabricius) is a serious herbivorous insect pest of soybean (Glycine max) in Asia and Oceania. Previously, we identified quantitative trait loci (QTLs) for CCW-antibiosis-resistance, CCW-1 and CCW-2, and ...

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

Importance of Antixenosis and Antibiosis Resistance to the Cabbage Whitefly (Aleyrodes proletella) in Brussels Sprout Cultivars

Insects, 2020
The cabbage whitefly Aleyrodes proletella (L.) (Hemiptera: Aleyrodidae) is an important pest of a wide range of vegetable Brassicas. Since the control of this pest is still challenging, new approaches such as the use of resistant cultivars are required ...

Levels of Tolerance, Antibiosis, and Antixenosis Among Resistant Buffalograsses and Zoysiagrasses

Journal of Economic Entomology, 2008
The western chinch bug, Blissus occiduus Barber, has been documented as one of the most serious pests of buffalograss, Buchloë dactyloides (Nuttall) Engelmann, and zoysiagrass, Zoysia japonica Steudel, grown for turf in midwestern states. Resistance to the western chinch bug has been identified in both buffalograsses and zoysiagrasses.

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 ...
