Effect of DIMBOA, an aphid resistance factor in wheat, on the aphid predator Eriopis connexa Germar (Coleoptera: Coccinellidae)
(Kluwer Academic Publishers-Plenum Publishers, 1992)
DIMBOA (2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one), a secondary metabolite found in cereal extracts, confers resistance in wheat to aphids. Its effect on beneficial organisms was tested on larvae of the aphid predator ...
Possible involvement of the phloem sealing system in the acceptance of a plant as host by an aphid
(Birkhauser Verlag AG, 1996)
Possible reasons for the rejection of some lines of Triticum monococcum (Tm44 and Tm46) by the aphid Sitobion avenae were explored. In all T. monococcum lines studied, whether unfavourable (non-host/resistant plant) or ...
Ingestion of the benzoxazinone dimboa from wheat plants by aphids
(1989)
DIMBOA (2,4-dihydroxy-7-methoxy- 1,4-benzoxazin-3-one was found in nymphs of the aphids Metopolophium dirhodum and Sitobion avenae which had fed on DIMBOA-containing wheat seedlings and artificial diets. DIMBOA levels found ...
Characterization of peroxidase changes in tolerant and susceptible soybeans challenged by soybean aphid (Hemiptera: Aphididae)
(Entomological Soc Amer, 2014-10-01)
Changes in protein content, peroxidase activity, and isozyme profiles in response to soybean aphid feeding were documented at V1 (fully developed leaves at unifoliate node, first trifoliate leaf unrolled) and V3 (fully ...
Differential expression of candidate defense genes of poplars in response to aphid feeding
(ENTOMOLOGICAL SOC AMER, 2009)
Species belonging to the genus Populus (poplars) produce a series of defensive proteins in response to insect damage. Proteinase inhibitors, polyphenol oxidases, and chitinases are the most relevant and intensively studied ...
Evaluation of late vegetative and reproductive stage soybeans for resistance to soybean aphid (hemiptera: Aphididae)
(2013-04-01)
The soybean aphid, Aphis glycines Matsmura, has become the most significant soybean [Glycine max (L.) Merrill] insect pest in the north central soybean production region of North America. The objectives of this research ...

Occurrence of diboa in wild Hordeum species and its relation to aphid resistance
(1991)
The secondary metabolise 2,4-dihydroxy-1,4-benzoxazin-3-one (DIBOA) was found in seedlings of wild Hordeum species, but not of cultivated barley (Hordeum vulgare). DIBOA levels correlated negatively with performance of the ...
Glycine-betaine accumulation influences susceptibility of water-stressed barley to the aphid Schizaphis graminum
(Pergamon-Elsevier, 1987)
Water deficit increased susceptibility of barley to the aphid Schizaphis graminum. Proline and glycine-betaine accumulated in the stressed plants. These compounds were incorporated into artificial diets to test their effects ...
Effect of DIMBOA, a hydroxamic acid from cereals, on peroxisomal and mitochondrial enzymes from aphids: Evidence for the presence of peroxisomes in aphids
(Kluwer Academic/Plenum Publishers, 1999)
2,4-Dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA), a hydroxamic acid involved in the resistance of cereals to aphids, was administered to adult individuals of the aphid Sitobion avenae in artificial diets. Effects on ...
