Buchnera aphidicola is an obligate symbiotic bacterium that sustains the physiology of aphids by complementing their exclusive phloem sap diet. In this study, we reappraised the transport function of different Buchnera strains, from the aphids Acyrthosiphon pisum, Schizaphis graminum, Baizongia pistaciae and Cinara cedri, using the re-annotation of their transmembrane proteins coupled with an e...

scales per 100 leaves varied from 3.3 to 8.7. Scales containing active forms of Aphytis numbered in excess of 18 per 100 healthy scales each month, and in one month were as high as 183 per 100 healthy scales. These figures demonstrate that Aphytis was active during each of the 15 months and present in sufficient numbers to hold purple scale at low level regardless of weather fluctuations. This ...

Root and crown rot (gummosis) is known as the most destructive disease affecting pistachio in Iran. The efficiency of bacterial strains to reduce the growth rate of Phytophthora pistaciae was studied under different electrical conductivities (EC, 0, 2, 4, 8, 12 ds/m). Soil and rhizosphere samples were collected from pistachio growing regions in Kerman province, Iran, during 2011 - 2012. Overall...

The common pistachio psylla, Agonoscena pistaciae (Homoptera: Psyllidae) is known as the key pest of pistachio trees in Iran. This study was carried out during three years to test the effect of dish washing detergent (Rika ® ) against this pest in a randomized complete block design with five treatments and four replicates. The treatments were including: 13500ml dish washing detergent per 1000 l...

The toxicological and biochemical characteristics of acetylcholinesterases (AChE) in nine populations of the common pistachio psyllid, Agonoscena pistaciae Burckhardt and Lauterer (Hemiptera: Psyllidae), were investigated in Kerman Province, Iran. Nine A. pistaciae populations were collected from pistachio orchards, Pistacia vera L. (Sapindales: Anacardiaceae), located in Rafsanjan, Anar, Bam, ...
