The small hive beetle (Aethina tumida, SHB) is an invasive pest of honey bee (Apis mellifera) colonies in the United States. The adult and larval beetles can ruin honey through fecal contamination and by vectoring a mutualistic yeast (Kodamaea ohmeri) that causes honey fermentation. These beetles also impact honey bee colonies by feeding on bee eggs, bee brood, and pollen. Severe beetle infestations can cause colonies to decline or abscond. The SHB has been present in the United States since at least 1998. Since then, there have been several published papers on how to successfully rear these beetles. Laboratory rearing of SHBs allows for immediate access to adults and immature stages without having to constantly collect them from infested bee colonies. A clean and cost effective method for rearing SHBs is presented in this thesis. There is little published information on the external morphology of the SHB. Murray, Schmolke, Menier, and Jouan were some of the few authors to publish on this subject. Photography of the adult and larval stages are provided with emphasis on the adult morphology. Chemical and cultural controls are typically used to keep SHBs at a tolerable level. Only a few articles have been published on the biological control of SHBs. While some generalist fungal pathogens and commercially available nematodes have been reported to attack SHBs, there have been no reports of any host-specific predators, parasitoids, or pathogenic protozoa, fungi, nematodes, bacteria, or viruses. One protozoan pathogen has been discovered in the process of writing this thesis, but little is known about its life cycle, the effects that it has on SHBs, and whether this pathogen infects other beetles or insects. Dissection techniques for the adults and larvae are discussed in this thesis.

Finally, small hive beetles are unique among other beetle species in their ability to find hiding places within the colony where they are confined by honey bee hosts (Chapter 6) until the ambient temperature decreases, whereafter the beetles enter the thermoregulatory cluster of honey bees (Chapter 7). The research presented herein contributes to a greater understanding of attributes of small hive beetles that enable them to integrate successfully into honey bee nests.

The small hive beetle (SHB, Aethina tumida) is an invasive pest species of honey bees with established populations on all continents except Antarctica. There is a lack of understanding of some of the mechanisms involved in the invasions of the SHB. In this thesis, the dispersal capacity and factors of importance for host-finding were studied under field conditions. It was found that the SHB is capable of long distance flights and uses host cues during dispersal. Additionally, successful pupation was shown in several greenhouse substrates and data obtained from laboratory studies was applied to global modelling data to show the impact under current and future climatic conditions. The results signify the opportunistic nature of the SHB and highlights that the future impact of the species will likely increase due to global warming. This thesis contributes to the knowledge needed to mitigate the impact of this invasive species around the world.

The small hive beetle (SHB), Aethina tumida Murray, was first detected in Australia in 2002. Since then it has become a major pest of bee hives, spreading rapidly throughout the eastern mainland states. When conditions are suitable, beetles lay their eggs within bee hives and honey sheds, often in the combs, either in the hive or in stored honey combs pre- or post-extraction. Hatching larvae then feed on the honey, pollen, bee eggs, bee larvae and brood. The resulting contamination of the honey renders it useless for extraction, thereby leaving beekeepers bereft of their main source of income from the hives. Beekeepers also face the cost of cleaning contaminated supers and hives and restoring colonies to full strength or even replacing colonies following heavy infestations. A number of strategies to minimise the impact of SHB are already in use in Australia, and include trapping devices, insecticide delivery mechanisms, modifications to hive designs, improved beekeeping techniques and hygienic procedures. However, SHB continues to cause large-scale economic losses within the industry. It is clear that a better understanding of the biology of the SHB is required if beekeepers are to effectively manage this pest using a sustainable, integrated approach. This project sought to elucidate a number of biological and behavioural characteristics of SHB that directly relate to damage in hives and honey houses. The research was aimed at generating data that would support and enhance the effectiveness of existing SHB control strategies as well as provide the basis for new strategies, for the commercial and amateur beekeeping industry.

The small hive beetle Aethina tumida is native to sub-Saharan Africa, where it is not generally considered a pest. Its arrival in 1996 in the south east of the United States was unexpected, as was the devastating effect it had on colonies. It has since spread to Australia, Canada, and Mexico. An isolated incursion in Portugal, Europe in 2004 was successfully eradicated. The discovery of the beetle in south west Italy in September 2014, and subsequent continuing control efforts have brought new attention to the beetle by beekeepers, scientists and governments. This book intended for beekeepers derives from a conference organised by the COLOSS association and held at CRA-API, Bologna, Italy. In its seven chapters the world's experts on the small hive beetle discuss its biology and spread, and suggest practical ways of living with the pest.
