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 ...
Variability in Grain Aphid (Homoptera: Aphididae) Performance and Aphid-Induced Phytochemical Responses in Wheat
(Entomological Society of America, 1997)
Aphid genotype has been shown to be a source of variability in the induction of phytochemical responses in wheat after aphid infestation as well as in their performance on wheat lines. Two clones of the aphid Sitobion ...
No risk, no gain? Limited benefits of a non-costly herbivory-induced defense in wheat
(Universite Laval, 1998)
Following a short-term infestation by aphids, wheat seedlings show an increase in their concentration of hydroxamic acids (Hx), secondary metabolites conferring resistance against insects. The benefits for a wheat cultivar ...
The distribution of Russian wheat aphid, Diuraphis noxia (Kurdjumov) (Hemiptera: Aphididae) in Turkey
(Academic Journalshttps://academicjournals.org/journal/AJAR/article-abstract/0D2D7D238003, 2013)
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 ...
Semiochemicals mediating spacing behavior of bird cherry-oat aphid, Rhopalosiphum padi feeding on cereals
(Springer New York LLC, 1997)
Olfactometry using an apterous individual of Rhopalosiphum padi (L.) showed an arresting effect by volatiles from a wheat seedling and a repellent effect by volatiles from a wheat seedling infested with aphids at a high ...
Characteristics of hydroxamic acid induction in wheat triggered by aphid infestation
(Springer New York LLC, 1997)
Hydroxamic acids (Hx) are natural products of Gramineae that are associated with cereal resistance to pests. We aimed at characterizing the induction of Hx accumulation in seedlings of wheat. Triticum aestivum, by short-term ...
Specialisation pattern of the aphid Rhopalosiphum maidis is not modified by experience on a novel host
(2001)
The effect of alternative host condition on the pattern of specialisation of the aphid Rhopalosiphum maidis (Fitch) was studied. R. maidis commonly occurs in Chile on Johnson grass (Sorghum halepense L.) but rarely on ...
Allocation of herbivory-induced hydroxamic acids in the wild wheat Triticum uniaristatum
(Birkhauser Verlag Basel, 1998)
We characterized the induction of hydroxamic acids (Hx) by aphid infestation in the wild wheat Triticum uniaristatum by addressing the following questions: i) Do different leaves have similar responses to aphid damage?, ...
Hydroxamic acid glucosides in honeydew of aphids feeding on wheat
(Kluwer Academic Publishers-Plenum Publishers, 1992)
DIMBOA glucoside (2-O-/gb-D-glucopyranosyl-4-hydroxy-7-meth-oxy-1,4-benzoxazin-3-one), the main hydroxamic acid (Hx) in intact wheat plants, was detected in the honey dew of Rhopalosiphum padi feeding on seedlings of six ...
