The behavior of ions in a Paul trap has been investigated using numerical solution of the set of Mathieus differential equations. Afterwards, the trajectories of two typical ions such as H+ and 208Pb+ in the trap have been obtained using the fourth-order Runge-Kutta method. For specific dimensions of a Paul trap and a given frequency, the stability regions for separation of H+ and 2H+ ions hav...

One of the most important pest in the Oak forest of Kurdistan province is Oak leaf roller moth, Tortrix viridana L. (Lep.: Tortricidae). Use of pheromone trap is one of the suitable methods for monitoring and controlling of the pest. In this work, three main factors which affect the efficiency of traps including trap type, pheromone dose and installation height trap were studied. Four types of ...
Triticale as a Potential Trap Crop for the Wheat Stem Sawfly (Hymenoptera: Cephidae) in Winter Wheat
Trap cropping involves the use of plant species or genotypes to attract pest insects away from main crop avoid damage. In this study, we evaluated potential using winter triticale (x Triticosecale ) as a trap for wheat stem sawfly ( Cephus cinctus Norton), an economically devastating Triticum aestivum L.). The larvae consume parenchyma tissue within and cut at base causing it lodge. Triticale i...
Abstract Distribution pattern and relative abundance of the agricultural rodent pests rain-fed irrigated areas district Swat Khyber Pakhtunkhwa, Pakistan were recorded from April 2011 to November 2013 using wire mesh live traps. A total 350 rodents (269 Rattus rattus 81 Mus musculus) captured under 2268 trap nights (trap success: 0.15). Regression daily captures on cumulative revealed an estima...
