Parasites and pathogens are implicated in honey bee colony losses, bees may also spread infection to wild pollinators. Bees consume nectar pollen, which contain phytochemicals that can positively or negatively affect pollinator health. Certain reduce parasite loads humans other animals. Understanding how survival could help identify optimal forage sources phytochemical treatments ameliorate disease. We fed seven dietary evaluate whether consumption would treat preexisting mature bees,...

The aim of this study was to improve cage systems for maintaining adult honey bee (Apis mellifera L.) workers under in vitro laboratory conditions. To achieve goal, we experimentally evaluated the impact different cages, developed by scientists international research network COLOSS (Prevention COlony LOSSes), on physiology and survival bees. We identified three cages that promoted good bees from exhibited greater had relatively lower titers deformed wing virus, suggesting virus is a...

Honey bees face numerous biotic threats from viruses to bacteria, fungi, protists, and mites. Here we describe a thorough analysis of microbes harbored by worker honey collected field colonies in geographically distinct regions Turkey. Turkey is one the World's most important centers apiculture, harboring 5 subspecies Apis mellifera L., approximately 20% bee world. We use deep ILLUMINA-based RNA sequencing capture species for sampling all non-endogenous carried bees. After trimming mapping...

Amygdalin, a cyanogenic glycoside, is found in the nectar and pollen of almond trees, as well variety other crops, such cherries, nectarines, apples others. It inevitable that western honeybees (Apis mellifera) consistently consume amygdalin during pollination season because crops are almost exclusively pollinated by honeybees. This study tests effects field-relevant concentration on honeybee microbes activities key genes. We executed two-month field trial providing sucrose solutions with or...

Diversity of ecological conditions in Anatolia enables many species to adapt different environments.Thus Turkey is inhabited by various strains A.m. mellifera Linnaeus, 1978; carnica, anatoliaca, caucasica, syriaca, and meda.Analysis mtDNA variants a widely used tool determine the phylogenetic relationships at subspecies levels.In this study sequencing results tRNA leu -COX2 ND5 gene segments were presented comparison with some previously published mitochondrial haplotypes.According UPGMA...

Turkish red pine (Pinus brutia) is a widespread and important forest tree species in Turkey, occurring mainly southern, western, northwestern while the natural occurrence of Aleppo halepensis) restricted to 2 locations found sympatrically with pine. In present study sympatric populations both from Muğla Adana provinces Turkey were sampled, internal transcribed spacer (ITS-2) region ribosomal DNA was comparatively studied sequence analysis. Analysis molecular variance (AMOVA) demonstrated...

Although silk has a very low share in textile use the world, it is an important trade product. However, few countries have say production and export. Despite efforts to boost silkworm breeding, which seen as traditional activity for Turkey, not reached level of past years. In current study, general evaluation world Turkey breeding was made example Silvan district Diyarbakır province given reveal situation country. For this purpose, survey conducted with seven people who continue district, 46...

Arılar, dünya çapındaki tüm tarımsal türlerin büyük çoğunluğu ve yabani flora için önemli tozlayıcılardır. Son yıllarda dünyadaki arı kolonilerinin sayısında hızlı bir düşüş yaşanmıştır. Bal arıları sosyal böceklerdir, bu da onları mikrobiyal patojenler parazitlerin hızla yayılmasına karşı hassas hale getirir. Koloni çöküşüne yol açan tek nedensel ajan tanımlanamaz işçi arılardaki azalmayla ilgili en yaygın biyolojik etkenlerden biri parazitik microsporidia Vairimorpha (Nosema) spp., esas...
