تولید چوب و میزان حساسیت و مقاومت کلنهای برتر صنوبر به آفات مهم، طی سالهای 1384 تا 1386 در ایستگاه تحقیقات کهنهکند بجنورد مورد بررسی قرار گرفت. در پایان هر دوره رویش با اندازهگیری قطر و ارتفاع این درختان، حجم کلنها محاسبه شد. همچنین نمونهبرداری از میزان خسارت پروانه زنبورمانند روی کلنها با شمارش سوراخهای ایجاد شده روی تنه و شاخه درختان و نمونهبرداری از میزان خسارت پروانه دمچنگالی با ا...

Sesia apiformis Paranthrene tabanifonnis Rott. were also identified occurrence tree species forest areas. In c...
The aim of this study was to predict the distribution and movement of populations of the tsetse fly, Glossina palpalis palpalis (Diptera: Glossinidae), in the wet and dry seasons and to analyze the impact of the use of mono-pyramidal traps on fly populations in the Kogo focus in 2004 and 2005. Three Glossina species are present in Kogo: Glossina palpalis palpalis, major HAT vector in West-Centr...
Partial DNA sequence data from the mitochondrial DNA (mtDNA) cytochrome oxidase I and II genes were used to construct a molecular phylogeny based on representative species from 10 of the 20 genera of Sesiidae. Maximum likelihood, maximum parsimony, and Bayesian analysis were utilized. Sequencing of a 606-base pair region of the mtDNA cytochrome oxidase I (COI), tRNA leucine, and COII gene revea...
Larvae of many species of Sesiidae, the clearwing moths, are important pests in commercial nurseries, urban landscapes, timber stands, vineyards, and orchards. They cause economic loss by larval boring in stems and roots of herbaceous and woody plants. Researchers and growers often monitor for the presence of economically important sesiid adults with pheromone traps. These traps often attract m...
