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 ...
Reaction of DIMBOA with amines
(1989)
DIMBOA (2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one), a hydroxamic acid from cereals, reacted with primary amines to give an addition compound with two imino groups. Kinetic studies with DIMBOA and with the DIMBOA analogues ...
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 ...
Effects of DIMBOA on detoxification enzymes of the aphid Rhopalosiphum padi (Homoptera: Aphididae)
(Elsevier Ltd, 2003)
The presence of glutathione transferases and esterase activity was investigated in Rhopalosiphum padi and the effects of the cereal hydroxamic acid, 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA) on these detoxification ...
Stimulatory effect of DIMBOA on NADH oxidation catalysed by horseradish peroxidase
(1997)
2,4-Dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA) effectively enhanced the rate of NADH oxidation catalysed by horseradish peroxidase isoenzyme C (HRPC), a reaction that generates H2O2. The effect showed saturation ...
Effects of hydroxamic acids on electron transport and their cellular location in corn
(1994)
DIMBOA, the main hydroxamic acid in maize and wheat, is found mainly as a glucoside in intact maize plants; when the tissue is damaged a β-glucosidase releases DIMBOA from DIMBOA-glucoside. The effects of DIMBOA and its ...
Effects of DIMBOA levels in wheat on the susceptibility of the grain aphid (Sitobion avenue) to deltamethrin
(1993)
The effects of DIMBOA in cultivars of wheat on aphid antibiosis and tolerance to the insecticide deltamethrin were investigated for the aphid Sitobion auenae. Over 48 hours the mean relative growth rate differed significantly ...
Evaluation of DIMBOA analogs as antifeedants and antibiotics towards the aphid Sitobion avenae in artificial diets
(Kluwer Academic/Plenum Publishers, 1999)
A total of 25 compounds including benzoxazinones, benzoxazolinones, and N-glyoxylamide derivatives were tested as antifeedants and antibiotics towards the aphid Sitobion avenae in diet bioassays. The antifeedant and mortality ...
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 ...
