متن کاملGenetic Structure of the Aphis craccivora (Hemiptera: Aphididae) From Thailand Inferred From Mitochondrial COI Gene Sequence
The cowpea aphid, Aphis craccivora Koch (Hemiptera: Aphididae), is one of the most destructive insect pests of legume plants worldwide. Although outbreaks of this pest occur annually in Thailand causing heavy damage, its genetic structure and demographic history are poorly understood. In order to determine genetic structure and genetic relationship of the geographic populations of this species,...

fumigant toxicity of camphor was studied against the aphid aphis craccivora koch and three associated natural enemies, i.e. coccinella undecimpunctata l., aphelinus albipodus hayat & fatima and aphidius colemani viereck. aphis craccivora was the most tolerant one compared with all tested natural enemies as the recorded lc50 values were 12.71, 6.33, 1.16 and 0.48 mg camphor/liter space for t...
متن کاملAntioxidant activity of the extracts of some cowpea (Vigna unguiculata (L) Walp.) cultivars commonly consumed in Pakistan.
The present investigation has been carried out to determine the antioxidant activity of the methanolic extracts obtained from four cultivars of cowpea (Vigna unguiculata (L) Walp.) seeds. Phenolic compounds present in the extracts showed the antioxidant and antiradical properties when investigated using a linoleic acid peroxidation model, FRAP, ORAC and TRAP assays, as well as DPPH, hydroxyl, n...
