Resistance to Rhopalosiphum padi (Homoptera: Aphididae) in three triticale accessions.
Experiments were conducted to identify and characterize host plant resistance to bird cherry-oat aphid, Rhopalosiphum padi (L.), in various wheat and wheat-grass hybrids. Initial tests screened for resistance to R. padi among 12 grass accessions (eight wheat [Triticum aestivum L.], three triticale [XTriticosecale Wittmack], and 1XElytricum [Elytrigia elongata [Host] Nevski x Triticum aestivum h...
متن کاملEffects of DIMBOA on detoxification enzymes of the aphid Rhopalosiphum padi (Homoptera: aphididae).
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 enzymes was studied. Activity of glutathione S-transferases and general esterases was determined for adult aphids feeding on a natural diet lacking DIMBOA and on an artif...
متن کاملDictyopteris serrata (Dictyotales, Phaeophyceae): A Little Known Algal Species Newly Recorded from Australia*
The brown alga Dictyopteris serrata (Areschoug) Hoyt (Dictyotales, Phaeophyceae) is reported from the coast of western Australia, representing the first reliable record of this species from outside the south-western Indian Ocean. Distinguishing features of D. serrata are: a broad thallus with marginal teeth, veins extending from the midrib obliquely towards the blade margin, and embedded tetras...
متن کاملA new species of Rhopalosiphum (Hemiptera, Aphididae) on Chusquea tomentosa (Poaceae, Bambusoideae) from Costa Rica
The new species Rhopalosiphum chusqueae Pérez Hidalgo & Villalobos Muller, is described from apterous viviparous females caught on Chusquea tomentosa in Cerro de la Muerte (Costa Rica). The identity of the species is supported both by the morphological features and by a molecular phylogenetic analysis based on a fragment of the mitochondrial DNA containing the 5' region of the cytochrome c oxid...
متن کاملRhopalosiphum padi (Hemiptera: Aphididae) responses to volatile cues from Barley yellow dwarf virus-infected wheat.
In choice bioassays, Rhopalosiphum padi L. nonviruliferous apterae preferentially locate near volatile organic compounds (VOCs) emitted from Barley yellow dwarf virus (BYDV)-infected wheat plants compared with VOCs from noninfected plants. However, the specific VOCs responsible for R. padi responses are unknown. It is unclear also if R. padi responses to BYDV-infected wheat are caused by arrest...
