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.

Aphid Antixenosis Mediated by Volatiles in Cereals
Acta Agriculturae Scandinavica, Section B - Soil & 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.

Antixenosis to the Soybean Aphid in Soybean Lines [PDF]
The Open Entomology Journal, 2011 The soybean aphid, Aphis glycines, is a pest of soybean in Asia, and it has become a major pest of this crop in North America with large outbreaks that cause significant yield loss. Host-plant resistance is one management tactic being developed against soybean aphid in North America, and resistance may be manifested as antixenosis, antibiosis, or ...

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 ...
