Impact Of Pesticides

Honey bee populations are declining as occurs with other pollinators. One suggested cause of this decline is the impact of pesticides. To improve bees’ health, pesticides and food sources may be monitored using sentinel hives, given that bees forage in a 2.5 km radius around the hive. We extracted 20 (twenty) bees, as well as samples of wax, honey and pollen from a sentinel hive. Six pesticides were detected in the samples, except for the honey. All detected pesticides in the sentinel hive are pro- hibited in Argentina. Eight different plant families and genera were detected in the honey and pollen samples. Our work suggests that monitoring pesticides with sentinel beehives will be useful to improve agricultural practices in the region.

The Impact

So far, larval rearing in vitro has been an important method in the assessment of bee toxicology, particularly in pesticide risk assessment. However, natural products are increasingly used to control honey bee pathogens or to enhance bee immunity, but their effects on honey bee larvae are mostly unknown. In this study, laboratory studies were conducted to determine the effects of including selected aqueous plant infusions in the diet of honey bee (Apis mellifera L.) larvae in vitro. The toxicity of infusions from three different plant species considered to be medicinal plants was evaluated: tansy (Tanacetum vulgare L.), greater celandine (Chelidonium majus L.), and coriander (Coriandrum sativum L.). The impact of each on the survival of the larvae of honey bees was also evaluated. One-day-old larvae were fed a basal diet consisting of distilled water, sugars (glucose and fructose), yeast extract, and freeze-dried royal jelly or test diets in which distilled water was replaced by plant infusions. The proportion of the diet components was adjusted to the age of the larvae. The larvae were fed twice a day. The experiment lasted seven days. Significant statistical differences in survival rates were found between groups of larvae (exposed or not to the infusions of tansy, greater celandine, and coriander). A significant decrease (p < 0.05) in the survival rate was observed in the group with the addition of a coriander herb infusion compared to the control. These results indicate that plant extracts intended to be used in beekeeping should be tested on all development stages of honey bees.

The Impact

This chapter considers VhaVenda indigenous knowledge about foods, its production, and its consumption as a way of exploring indigenous-based solutions to food insecurity. External and internal factors contributing to food insecurity are discussed, beginning with an overview of the current state of food insecurity globally and then locally. Subsequently, the chapter discusses the impact of the COVID-19 pandemic on food security levels in both urban and rural settings within a single population. Specific attention is given to the rural setting of Thohoyandou Venda, drawing attention to its challenges and solution-possibilities with particular focus on subsistence farming and home gardening as aspects in VhaVenda culture. Finally, the authors provide a catalogue of indigenous food sources and agricultural practices thereby exploring local knowledge as a possible mechanism to combat food insecurity in the contemporary period.

Honey Yield

The main objective of this study was to determine the impact of Lactobacillus salivarius A3iob, a honey bee gut-associated strain (GenBank code access KX198010), on honey yield. Independent assays were conducted from May to September 2014 and 2015, in three commercial apiaries: Tilquiza, El Carmen and Yala, all located in north-western Argentina. Local Apis mellifera L. bees were kept in standard Langstroth hives; treated hives were fed once a month with 1×105 cfu/ml viable Lactobacillus cells, administered to the bees through a Doolittle-type feeder in 125 g/l sucrose syrup. Control hives were only given the syrup mixed with MRS sterile broth. The main honey harvest was done in December in all groups and we found that there was an overall increase in honey yield from the treated hives. In 2014, all treated hives produced between 2.3 to 6.5 times more honey than the controls. However, in 2015, higher honey average yields in the treated hives at El Carmen and Yala were obtained, yet not at Tilquiza, because of a slight mishap. They experienced the swarming of several bee colonies due to a higher number of bees without appropriate management, which caused the control group to yield more honey compared to the hives fed with Lactobacillus. Interestingly, at El Carmen, two honey harvests were recorded: one in winter and another in summer (July and December 2015, respectively). This unexpected result arose from the particular flora of the region, mainly Tithonia tubaeformis, which blooms in winter. L. salivarius A3iob cells prove to be a natural alternative that will positively impact the beekeepers’ economy by providing a higher honey yield.

Paralysis Virus

Recent declines in honey bee (Apis mellifera L., 1758) populations worldwide have spurred significant research into the impact of pathogens on colony health. The role of the Israeli acute paralysis virus (IAPV) on hive mortality has become of particular concern since being correlated with colony losses. However, the molecular interactions between IAPV and its host remain largely unknown. To investigate changes in host protein expression during IAPV infection, mass-spectrometry-based quantitative proteomics was used to compare IAPV-infected and healthy pupae. Proteins whose expression levels changed significantly during infection were identified and functional analysis was performed to determine host systems and pathways perturbed by IAPV infection. Among the A. mellifera proteins most affected by IAPV, those involving translation and the ubiquitin–proteasome pathway were most highly enriched and future investigation of these pathways will be useful in identifying host proteins required for infection. This analysis represents an important first step towards understanding the honey bee host response to IAPV infection through the systems-level analysis of protein expression.
