“…Bee inspectors recorded if clinical signs of American Foulbrood (AFB), Chronic Bee Paralysis Virus (CBPV), Chalkbrood, European Foulbrood (EFB), Nosemosis, Varroosis or Sacbrood were visible (Table 1 for list of clinical signs). Furthermore, they searched visually for the bee pests Aethina tumida (Small Hive Beetle) [28, 29] and Tropilaelaps spp. (Tropilaelaps-mite) [30].…”

Health status of honey bee colonies (Apis mellifera) and disease-related risk factors for colony losses in Austria

Austrian beekeepers frequently suffered severe colony losses during the last decade similar to trends all over Europe. This first surveillance study aimed to describe the health status of Austrian bee colonies and to analyze the reasons for losses for both the summer and winter season in Austria. In this study 189 apiaries all over Austria were selected using a stratified random sampling approach and inspected three times between July 2015 and spring 2016 by trained bee inspectors. The inspectors made interviews with the beekeepers about their beekeeping practice and the history of the involved colonies. They inspected a total of 1596 colonies for symptoms of nine bee pests and diseases (four of them notifiable diseases) and took bee samples for varroa mite infestation analysis. The most frequently detected diseases were three brood diseases: Varroosis, Chalkbrood and Sacbrood. The notifiable bee pests Aethina tumida and Tropilaelaps spp. were not detected. During the study period 10.8% of the 1596 observed colonies died. Winter proved to be the most critical season, in which 75% of the reported colony losses happened. Risks for suffering summer losses increased significantly, when colonies were weak in July, had queen problems or a high varroa mite infestation level on bees in July. Risks for suffering winter losses increased significantly, when the colonies had a high varroa mite infestation level on bees in September, were weak in September, had a queen older than one year or the beekeeper had few years of beekeeping experience. However, the effect of a high varroa mite infestation level in September had by far the greatest potential to raise the winter losses compared to the other significant factors.

“…Ideally, beeswax shipments are not contaminated prior to sending. However, this appears notoriously difficult in regions with SHB populations due to the highly mobile and cryptic behaviour of the adult beetles 10,40 . Regardless of the actual beeswax processing stage 33,34 , adult SHBs are therefore very likely to invade and successfully hide in any beeswax trade package.…”

International beeswax trade facilitates small hive beetle invasions

International trade can facilitate biological invasions, but the possible role of beeswax trade for small hive beetles (SHBs), Aethina tumida Murray (Coleoptera: Nitidulidae) is poorly understood. SHBs are parasites of social bee colonies native to sub-Saharan Africa and have become an invasive species. Since 1996, SHBs have established in all continents except Antarctica. Here, we combine mitochondrial DNA analyses ( COI gene, N = 296 SHBs, 98 locations) with previously published beeswax trade data (FAO) for 12 confirmed SHB invasions. Our genetic data confirm previous findings and suggest novel SHB African origins. In nine out of 12 invasion cases, the genetic and beeswax trade data match. When excluding one confirmed pathway (bee imports) and two cases, for which no FAO data were available, the genetics and beeswax trade data consistently predict the same source. This strongly suggests that beeswax imports from Ethiopia, South Africa, Tanzania and the USA, respectively, have mainly been responsible for the past invasion success of this beetle species. Adequate mitigation measures should be applied to limit this key role of beeswax imports for the further spread of SHBs. Combining genetics with trade data appears to be a powerful tool to better understand and eventually mitigate biological invasions.

“…Specifiek wanneer er gezocht wordt naar lage aantallen kevers bij een eerste introductie. Belangrijk bij visuele inspectie is kennis over het natuurlijke gedrag van de KBK (Cornelissen et al 2018). 1) KBKs hebben verschillende manieren om zich te ontdoen van gevaar, ze zullen wegrennen, zich verschuilen, zich laten vallen of wegvliegen.…”
