The Role Of Viral And Parasitic Factors In Bee Colony Losses İn Iğdır Province

Abstract

Colony losses in honey bees; It is caused by many factors such as care and feeding errors, pesticides, bee diseases and pests, global warming and stress. Viral and some parasitic infections, which are among the bee diseases, can cause significant economic losses in bee holdings and, from time to time, colony extinction. In this study, the role of viral and parasitic factors in colony losses observed in honey bee enterprises engaged in beekeeping and making their living from this activity in Iğdır province was investigated. For this purpose, seven viral agents in 64 bee farms with colony loss; Acute bee paralysis virus (ABPV), Chronic bee paralysis virus (CBPV), Black queen cell virus (BQCV), Deformed wing virus (DWV), Sacbrood bee virus (SBV), Cashmere bee virus (KBV), Israel acute bee paralysis virus (IAPV) and two parasitic agents; Examined for Nosema apis/cerana and Varroa. For this purpose, samples of 64 bee farms with colony loss in the spring of 2021 were analyzed. ABPV, BQCV, CBPV, DWV, KBV, SBV and IAPV factors were found to be 1.56%, 76.56%, 4.68%, 50%, 1.56%, 81.25%,20.31%, respectively, in honey bee enterprises with colony loss. Nosema cerana was positive at a rate of 60.93%, and N.apise was not found. In addition, in any of the bee farms with colony loss, Varroa sp. not detected. As a result, it is thought that mixed infections are seen in bee holdings with colony loss and these mixed infections are thought to be effective in colony losses.

Iğdır İlinde Görülen Arı Kolonisi Kayıplarında Viral ve Paraziter Etkenlerin Rolü

Abstract

Bal arılarında görülen koloni kayıplarında bakım ve beslenme hataları, pestisitler, arı hastalıkları ve zararlıları, küresel ısınma ve stres gibi birçok faktör rol oynamaktadır. Arı hastalıkları arasında yer alan viral ve paraziter enfeksiyonlar arı işletmelerinde önemli ekonomik kayıplara ve zaman zaman da kolonilerin sönmesine neden olabilmektedir. Bu çalışmada, Iğdır ilinde bulunan, koloni kaybı geçmişi olan 64 işletme belirlenmiş, bu işletmeleride görülen koloni kayıplarında viral, paraziter ve mikrosporodial etkenlerin rolü araştırılmıştır. Bu amaçla yedi viral etken; Akut arı felci virusu (Acute Bee Paralysis Virus-ABPV), kronik arı felci virusu (Cronic Bee Paralysis Virus-CBPV), siyah kraliçe hücre virusu (Black Queen Cell Virus-BQCV), deforme kanat virusu (Deforme Wing Virus-DWV), torba çürüklüğü virusu (SacBrood Virus-SBV), Kaşmir arı virusu (Kashmir Bee Virus-KBV), İsrail akut arı felci virusu (Israeli Acute Paralysis Virus-IAPV) ile nosemosis ve varroasis yönünden incelenmiştir. Araştırma sonunda viral etkenlerden ABPV, BQCV, CBPV, DWV, KBV, SBV ve IAPV sırasıyla %1.56, %76.56, %4.68, %50, %1.56, %81.25, %20.31 oranlarında; mikrosporodial hastalıklardan nosemosis % 60.93 oranında bulunmuştur. Nosemosise neden olan etken Nosema ceranae olarak belirlenmiştir. Ayrıca koloni kaybı gözlenen arı işletmelerinin hiçbirinde Varroa sp. tespit edilmemiştir. Sonuç olarak, koloni kaybı gözlenen arı işletmelerinde miks enfeksiyonların görüldüğü ve bu görülen miks enfeksiyonların koloni kayıplarında etkili olabileceği düşünülmektedir.
