In winter 1997 severely infested pistachio nuts were collected from orchards in Borkhar district of Isfahan to determine minimum threshold temperature and thermal constants. Minimum threshold temperatures were calculated according to rate of development or X-intercept method and the least coefficient of variation method. Thermal constants were calculated for different developmental stages in th...

 The stable colloidal dispersions of magnetic nano-particles in nematic liquid crystals are called ferronematics. Their behaviour in magnetic fields depends on various parameters such as anchoring energy, magnetic anisotropy, and shape and volume fraction of the particles. In the present paper, the threshold field is obtained for these colloidal nematics. Then, the influence of magnetic anisotr...

The pistachio twig borer moth, Kermania pistaciella Amsel (Lep.: Tineidae) is one of the most important pests of pistachio trees (Pistacia vera L.) in Iran. This study was carried out in two pistachio orchards of Rafsanjan area. Periods of pupal cocoon and adult emergence were recorded in two pistachio orchards for four years. Minimum threshold temperatures were calculated according to the leas...
