And Control

Abstract The small hive beetle Aethina tumida is an endemic parasitic pest and scavenger of colonies of social bees indigenous to sub-Saharan Africa. In this region this species rarely inflicts severe damage on strong colonies since the bees have developed strategies to combat them. However, A. tumida has since ‘escaped’ from its native home and has recently invaded areas such as North America and Australia where its economic impact on the apiculture industry has been significant. Small hive beetle, should it become established within Europe, represents a real and live threat to the UK bee keeping industry. Here we review the biology and current pest status of A. tumida and up to-date research in terms of both chemical and biological control used against this honey bee pest.

Several traits make stingless bees attractive to parasites of honey bee colonies. The small hive beetle (SHB) Aethina tumida, a honey bee colony scavenger/parasite native to sub-Saharan Africa, where is considered only a minor pest, is now present on almost all continents, including the Latin America region in South America. SHB has been recorded in Brazil since 2016 in Africanized honey bees and generaly the beetle does not seem cause negative impacts. European honey bees, on the other hand, suffer considerable damage when parasitized by SHB, suggesting a potential threat to other susceptible social bees. The present study reports the first occurrence of SHB in stingless bees in Brazil, and is an alert to authorities and stingless beekeepers to prevent infestations.

Thaumatotibia leucotreta, known as the false codling moth, is a pest of citrus and other crops in sub-Saharan Africa. As it is endemic to this region and as South Africa exports most of its citrus around the world, T. leucotreta has phytosanitary status for most markets. This means that there is zero tolerance for any infestation with live larvae in the market. Consequently, control measures prior to exporting must be exemplary. Certain markets require a standalone postharvest disinfestation treatment for T. leucotreta. However, the European Union accepts a systems approach, consisting of three measures and numerous components within these measures. Although effective preharvest control measures are important under all circumstances, they are most critical where a standalone postharvest disinfestation treatment is not applied, such as within a systems approach. Conventional wisdom may lead a belief that effective chemical control tools are imperative to achieve this end. However, we demonstrate that it is possible to effectively control T. leucotreta to a level acceptable for a phytosanitary market, using only biological control tools. This includes parasitoids, predators, microbial control, semiochemicals, and sterile insects. Simultaneously, on-farm and environmental safety is improved and compliance with the increasing stringency of chemical residue requirements imposed by markets is achieved.

And Control

Heartwater is a serious limiting factor for sheep and goat production in the major endemic area of sub-Saharan Africa and therefore most knowledge, research and control methods originate from this region. Whilst the usual or common clinical presentations can be used to make a presumptive diagnosis of heartwater with a good measure of confidence, this is not always the case, and animals suffering from heartwater may be misdiagnosed because their cases do not conform to the expected syndrome, signs and lesions. One aberrant form found occasionally in the Channel Island breeds of cattle and some goats is an afebrile heartwaterlike syndrome. The most constant and characteristic features of this heartwater-like syndrome comprise normal temperature, clinical signs associated with generalised oedema, and nervous signs, especially hypersensitivity. The presumption that the disease under investigation is the afebrile heartwater-like syndrome entails a tentative diagnosis based on history and clinical signs and the response to presumed appropriate treatment (metadiagnosis). The afebrile heartwater-like syndrome presents similarly to peracute heartwater but without the febrile reaction. Peracute cases of heartwater have a high mortality rate, enabling confirmation of the disease on post-mortem examination. Recognition of the afebrile heartwater-like syndrome is important to prevent deaths and identify the need for appropriate control measures.

The Impact

Purpose The rise in malaria deaths discloses a decline of global malaria eradication that shows that control measures and fund distribution have missed its right of way. Therefore, the purpose of this paper is to study and evaluate the impact and control of malaria on the independent states of the Sub-Saharan African (SSA) region over the time period of 2010–2017 using Deng’s Grey incidence analysis, absolute degree GIA and second synthetic degree GIA model. Design/methodology/approach The purposive data sampling is a secondary data from World Developmental Indicators indicating the incidence of new malaria cases (per 1,000 population at risk) for 45 independent states in SSA. GIA models were applied on array sequences into a single relational grade for ranking to be obtained and analyzed to evaluate trend over a predicted period. Findings Grey relational analysis classifies West Africa as the highly infectious region of malaria incidence having Burkina Faso, Sierra Leone, Ghana, Benin, Liberia and Gambia suffering severely. Also, results indicate Southern Africa to be the least of all affected in the African belt that includes Eswatini, Namibia, Botswana, South Africa and Mozambique. But, predictions revealed that the infection rate is expected to fall in West Africa, whereas the least vulnerable countries will experience a rise in malaria incidence through to the next ten years. Therefore, this study draws the attention of all stakeholders and interest groups to adopt effective policies to fight malaria. Originality/value The study is a pioneer to unravel the most vulnerable countries in the SSA region as far as the incidence of new malaria cases is a concern through the use of second synthetic GIA model. The outcome of the study is substantial to direct research funds to control and eliminate malaria.

African swine fever (ASF) is a viral disease of domestic pigs and wild boar. Due to the very serious socioeconomic consequences, the disease isone of the most important ones nowadays. African swine fever is an enzootic disease in many countries in Sub-Saharan Africa, in Sardinia, and TransCaucasus countries. Aft er its occurrence in Georgia in 2007, ASF spread to Armenia and Russian Federation, and in 2008. to Azerbaijan. Since then,its progressive moving toward the west has been recorded. Despite the number of undertaken preventive and control measures in the EuropeanUnion (EU), ASF has been still spreading. During 2017, the disease has been reported in domestic pigs in Estonia, Italy-Sardinia, Latvia, Lithuania,Poland, Romania, and Ukraine. ASF cases in domestic pigs have also been reported in Moldova in 2017. Th e number of diagnosed cases in wild boarin 2017 is much higher than in domestic pigs. ASF outbreak in wild boar in the Czech Republic well describes the possible viral „jump“ into a newregion. Th e source of infection hasn’t been confi rmed yet, but it is common that such leaps are due to either swill feeding or improperly disposal of food rather than to the animal movements. Since the lack of eff ective vaccine makes eradication even more diffi cult, the prevention of viral entry into the new areas is of the most importance. With the same aim, since 2011. the surveillance of ASF has been implemented in Serbia.

Small hive beetle (SHB) Aethina tumida (Order Coleoptera، Family Nitidulidae ) is an exotic pest of honeybee colonies، native to Sub-Saharan Africa. It has been found in several of the world over the past few decades. Adults are small، their color ranges from reddish-brown to dark brown (almost black) ، and its life cycle passes through four stages، egg، larva and adult after pupping period in the soil. The beetles are attracted to a number of odors from bee colonies، and can multiply to huge numbers within infested colonies where it eat brood، honey and pollen. In certain conditions، the (SHB) destroys combs and cause comb damage and honey spoilage through feeding and defecation. If beetle infestation is very high and uncontrolled، they ultimately destroy colonies or cause them to abscond.

The Small Hive Beetle (Aethina tumida Murray, 1867) is an invasive scavenger of honeybees. Originally endemic in sub-Saharan Africa, it is regulated internationally in order to preserve the areas still free from this species. To ensure the reliability of official diagnoses in case of introduction, an inter-laboratory comparison was organised on the identification of A. tumida by morphology and real-time PCR. Twenty-two National Reference Laboratories in Europe participated in the study and analysed 12 samples with adult coleopterans and insect larvae. The performance of the laboratories was evaluated in terms of sensitivity and specificity. Sensitivity was satisfactory for all the participants and both types of methods, thus fully meeting the diagnostic challenge of confirming all truly positive cases as positive. Two participants encountered specificity problems. For one, the anomaly was minor whereas, for the other, the issues concerned a larger number of results, especially real-time PCR, which probably were related to inexperience with this technique. The comparison demonstrated the reliability of official diagnosis, including the entire analytical process of A. tumida identification: from the first step of the analysis to the expression of opinions. The performed diagnostic tools, in parallel with field surveillance, are essential to managing A. tumida introduction.

The initial bedside care of premature babies with an intact cord has been shown to reduce mortality; there is evidence that resuscitation of term babies with an intact cord may also improve outcomes. This process has been facilitated by the development of bedside resuscitation surfaces. These new devices are unaffordable, however, in most of sub-Saharan Africa, where 42% of the world’s 2.4 million annual newborn deaths occur. This paper describes the rationale and design of BabySaver, an innovative low-cost mobile resuscitation unit, which was developed iteratively over five years in a collaboration between the Sanyu Africa Research Institute (SAfRI) in Uganda and the University of Liverpool in the UK. The final BabySaver design comprises two compartments; a tray to provide a firm resuscitation surface, and a base to store resuscitation equipment. The design was formed while considering contextual factors, using the views of individual women from the community served by the local hospitals, medical staff, and skilled birth attendants in both Uganda and the UK.

Background:Rheumatological diseases are common in Sub-Saharan Africa [1] but specialist healthcare is limited and there are less than 150 rheumatologists currently serving 1 billion people in Sub-Saharan Africa [2]. Rheumatologists practising in the UK NHS are likely to be exposed to migrant patients. There is therefore, an unmet need for health care providers to understand the differences in rheumatology healthcare provision between Sub-Saharan Africa and the UK and the barriers which migrants face in their transition of rheumatology care.Objectives:To gain an understanding of the experiences of patients with rheumatological conditions, about their past healthcare in Sub-Saharan Africa and their transition of care to the UK.Methods:A qualitative study using semi-structured interviews was conducted. Participants were recruited from two rheumatology outpatient clinics in London. Thematic analysis was applied to identify key themes.Results:Seven participants were recruited. Five had rheumatoid arthritis, one had ankylosing spondylitis and one had undifferentiated inflammatory arthritis. Participants described the significant impact their rheumatological conditions had on their physical and emotional wellbeing, including their social and financial implications. Compared to the UK, rheumatology healthcare in Sub-Saharan Africa was characterised by higher costs, limited access to specialists, lack of investigations and treatments, the use of traditional medicines and poor communication by clinicians. Barriers to transition of rheumatology care to the UK were: poor understanding of rheumatological conditions by the public and primary care providers, lack of understanding of NHS entitlements by migrants, fear of data sharing with immigration services and delayed referral to specialist care. Patient, doctor and public education were identified by participants as important ways to improve access to healthcare.Conclusion:This study has described, for the first time, patients’ perspectives of rheumatology health care in Sub-Saharan Africa and the transition of their care to the UK. These initial findings allow healthcare providers in the UK to tailor management for this migrant population and suggests that migrants need more information about their NHS entitlements and specific explanations on what non-clinical data will be shared with immigration services. To increase access to appropriate care, a concerted effort by clinicians and public health authorities is necessary to raise awareness and provide better education to patients and migrant populations about rheumatological conditions.References:[1]G.

The latest HIV data for 2007 has recently been published for the United Kingdom (UK). During the year, an estimated 6,840 (95% confidence intervals 6,600-7,050) persons (adjusted for reporting delays) were newly diagnosed with HIV in the UK. This represents a 12% decline from a peak of new HIV diagnoses reported in 2005 (7,800). Almost all this decline in new HIV diagnoses was in HIV-infected heterosexuals from sub-Saharan Africa who were probably infected in their country of origin.
