Various bee pests cause yield losses in honey bees and/or hive collapse. The most important is the small beetle (Aethina tumida), which has become one of biggest problems today's beekeeping. national study investigated beetles hives for first time Türkiye. In addition, distribution moths, oil beetles, and lice was examined. As research material, worker honeycomb samples were taken from 401 apiaries 40 provinces throughout A total 1199 healthy examined parasitologically terms larvae adult...

Turkey is in an essential geographic position for transmitting honey bee diseases from Asia to Europe. This study investigated Tropilaelaps mercedecae and Euvarroa sinhai, a potential risk European beekeeping, the first time throughout Turkey. In addition, situation of varoasis has been comprehensively revealed. total, 1199 colonies 401 apiaries were examined 40 provinces About 200 workers 10-cm2 honeycomb with capped brood cells collected each hive. While species not found, varroasis was...

Honey bees, Apis mellifera L. (Hymenoptera: Apidae), are the most important pollinators of agricultural products and plants in natural environment. Honeybees an ecosystem component due to their role nature production. Bacterial, fungal, viral, parasitic factors bee farms among causes honey colony losses. diseases (bacterial, fungal viral) parasites limiting beekeeping development production efficiency Türkiye. In addition caused by bacterial agents, viral agents very diverse. Viruses,...

This study was performed to determine the antibacterial activity of methanol extracts 23 bryophyte species against Paenibacillus larvae isolates that cause American foulbrood diseases in honeybee larvae. The honey and larva samples were collected from nine different locations Rize Turkey. A total 22 gram-positive spore-forming bacteria isolated samples. According results morphological, biochemical, molecular (16S rRNA gene sequencing) tests, 10 identified as P. (Polytrichum formasum,...

Paratuberculosis is a zoonotic disease caused by Mycobacterium avium subsp. paratuberculosis (MAP) in cattle. MAP may cause the formation of reactive oxygen species (ROS) increasing release proinflammatory cytokines host. Due to increase ROS, oxidant-antioxidant balance be disrupted and oxidative stress occur. The aim study was determine parameters cattle infected with paratuberculosis. For this purpose, 15 sera that were positive for clinically healthy 30 used as control group. In samples...

Paenibacillus larvae (P. larvae) is a pathogenic bacterium causing American Foulbrood Disease (AFB) in honeybee larvae. It necessary to develop alternative strategies for the control of this disease due serious colonies loses and use antibiotics. Recent studies are aimed at investigating natural fighting agents against P. In our study, it was demonstrate potential antibacterial efficacy ethanol extract Anatolian Propolis (EAP) strains PB35 SV35 which were isolated Turkey. The total phenolic...

Neosporozis, Neospora caninum’un neden olduğu, sığırlarda aborta olan enfeksiyöz bir hastalıktır. Hastalık, büyükbaş hayvan yetiştiriciliğinde önemli ekonomik kayıplara olmakta ve son yıllarda abortların başlıca nedenleri arasında yer almaktadır. Bu çalışma, Orta Karadeniz Bölgesinde (Amasya, Samsun Tokat illeri) hayvancılığın yoğun olarak yapıldığı işletmelerde abort yapan 136 sığıra ait atık fetüslerde sp. varlığını prevalansını belirlemeyi hedeflemektedir. caninum'un teşhisi için...

AbstractGiven the increasing interest in alternative methods of prevention and biological control bacterial diseases honey bees, development new approaches based on probiotic bacteria for bee growth, immune function defense is important. Honey bees have a rich microbiota that varies with seasonal geographic changes, developmental stages, diet, social lifestyle. Nevertheless, lactic acid are an integral part microbiota. In this study, strains Apilactobacillus, Leuconostoc Enterococcus...

Bacterial diseases, such as American Foulbrood (AFB) and European (EFB), are known to have catastrophic effects on honey bees (if left spread, can wipe out entire colonies), leading severe financial losses in the beekeeping industry. The aim of this study was evaluate pharmacological properties methanol extract its fractions (ethyl acetate, hexane, water) derived from Dicranum scoparium Hedw., which could be utilized a potential drug prevent bacterial diseases (AFB EFB) affecting bees. For...

Abstract Acarapis woodi (Rennie, 1921) (Acari: Tarsonemidae) is one of the mites that settles in respiratory system honeybees ( Apis mellifera L. (Hymenoptera, Apidae)) and distributed throughout world. It causes significant economic losses on honey production. In Türkiye, studies existence A. are very limited so far, no molecular diagnosis phylogenetic it have been reported Türkiye. This study was conducted to investigate prevalence especially areas where beekeeping intense. Diagnosis...
