Aphidicidal Activity of Different Aqueous Extracts of Bitter Apple Citrullus Colocynthis (l.) against the Bird Cherry-oat Aphid, Rhopalosiphum Padi (l.) (homoptera: Aphididae) under Laboratory Conditions
The impacts of aqueous extracts from different parts (root, stem, leaf and fruit) of bitter apple Citrullus colocynthis (Cucurbitales: Cucurbitaceae), with five different concentrations, on controlling the bird cherry-oat aphid, Rhopalosiphum padi (L.) (Homoptera: Aphididae) were investigated under laboratory conditions. Results showed that the effects of the aqueous extracts from different par...
متن کاملResistance 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 کاملLanding Preference and Reproduction of Rhopalosiphum padi (Hemiptera: Aphididae) in the Laboratory on Three Maize, Potato, and Wheat Cultivars
The bird cherry-oat aphid Rhopalosiphum padi (L.) transmits the nonpersistent Potato virus Y (PVY) to seed potatoes. Planting a nonvirus host plant around the main crop can reduce PVY incidence, because aphids tend to land in high numbers at the edge of a field and the crop border acts as a virus sink. This study determined R. padi landing and settling preferences and reproductive rates on thre...
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 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...
