in the current study some information is presented about the distribution and associations between alfalfa aphids and their parasitoids in different regions in 11 provinces of iran, as well as an identification key to the parasitoids. the main aphids were therioaphis trifolii maculata (buckton) and acyrthosiphon pisum (harris) followed by aphis craccivora koch and acyrthosiphon kondoi shinji. t...

The performance of cowpea aphid, Aphis craccivora Koch. (Hemiptera: Aphididae), on five faba bean, Vicia faba L. (Fabales: Fabaceae) cultivars was evaluated. Colony development, biology, and demographic parameters were studied to measure the cowpea aphid performance. Two methods, whole plant and detached leaf, were used in these experiments. After 14 d , the number of apterous adult, nymphs, an...

A study was carried out to determine the effectiveness of newly synthesized chemical ‘4-[3-(4-biphenylyl)-1, 6-dihydro-6-iminopyridazin-1-yl] butyronitrile hydro bromide against beanaphid, Aphis craccivora, under six treatments: T1 (20 ppm), T2 (40 T3 (60 T4 (80 T5 (100 and untreated control T6. Aphid numbers peaked in January it zero February. The best efficacy administered doses found followe...
