The Madras Presidency’s Prisons and the British Empire, 1820s–1850s

This paper is based on the observation that projects to reform prisons in British India in the first half of the 19th century were remarkably parallel to those in Britain and other colonies of the British Empire. Therefore, it will be asked to what extent local discussions about imprisonment in India were connected to developments in the metropole, in other parts of the empire, and elsewhere in the colony and how such imperial connections influenced local practices. Recent studies on colonial India’s prisons have focused on the British possessions in north India, whereas the Madras Presidency’s penal history is as of yet mostly unstudied. The paper will look on two initiatives of prison reform undertaken by the Madras Government; firstly, an inquiry made in the 1820s to combat the high mortality in the jails, and secondly, attempts throughout the 1840s and 1850s to construct a penitentiary along the lines of penal systems in other parts of India and the British Empire. The two case studies promise insights into the body of knowledge about punishment that was accumulated in British India, its entanglement with debates in other parts of the empire, and the emergence of ‘imperial standards’ of imprisonment in the course of the 19th century.

Potential for virus transfer between the honey bees Apis mellifera and A. cerana

Viruses seem to play a key role in European honey bee, Apis mellifera health, and have a much broader host spectrum than previously thought. Few studies have investigated interspecific virus transfer within the genus Apis. The introduction of A. mellifera into Asia exposed endemic Apis species to the risk of obtaining new viruses or viral strains and vice versa. To investigate the potential for host shifts, virus prevalence and sequences were monitored over three years in single and mixed-species apiaries hosting introduced A. mellifera and endemic Apis cerana. Deformed wing virus (DWV), Israeli acute paralysis virus (IAPV), black queen cell virus (BQCV), and sacbrood virus (SBV) were found, but not KBV, VDV-1, ABPV, or CBPV. Virus infections and prevalence were generally lower in A. cerana compared to A. mellifera, and varied over the years. The sequence data provided evidence for interspecific transfer of IAPV, BQCV, and DWV, but SBV strains seem to be species specific. Prevalence and sequence results taken together indicate that interspecific transfers of viruses are rare, even if honey bees are kept in close proximity. We discuss the pattern observed in the context host specificity and resistance. Our understanding of the extent of these exchanges is limited by a lack of knowledge on the mechanisms of adaptation of viruses to different hosts.

Associations among Nosema spp. fungi, Varroa destructor mites, and chemical treatments in honey bees, Apis mellifera

Nosema spp. and Varroa destructor are common parasites of honey bee colonies. Beekeepers routinely treat colonies with the fungicide fumagillin to control Nosema and an array of miticides to control V. destructor. Interactions between these parasites and chemical treatments are poorly understood. We allocated honey bee colonies to distinct chemical treatment regimes and monitored parasite intensities in the subsequent year. Infections of Nosema and infestations of V. destructor were positively correlated. Fumagillin was effective at mitigating Nosema intensities only over the short term, suggesting that biannual application is essential. V. destructor intensities were higher in colonies that had been previously treated with miticides, reasons for this warrant further investigation.
