The Impact of Nosema apis Z. Infestation of Honey Bee (Apis
mellifera L.) Colonies after Using Different Treatment Methods and their
Effects on the Population Levels of Workers and Honey Production on Consecutive
Years

The parasite, Nosema apis, was found to be widespread among feral populations of honey bees (Apis mellifera) in the south-west of Western Australia. The location, month of collection and whether the feral colony was enclosed in an object or exposed to the environment, all affected the presence and severity of infection. There was no significant difference in the probability of infection between managed and feral bees. However, when infected by N. apis, managed bees appeared to have a greater severity of the infection.

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.

Significant Difference

Present re search was formulated to find out how honey extraction frequencies influence colony growth and honey production of European honey bee Apis mellifera colonies. Colonies were equalized in terms of food and brood before starting experiment and were subjected to three types of honey extraction frequencies namely single, two and regular/ farmer’s practices. Observations were recorded fortnightly throughout the honey flow season for two consecutive years (2014-16). As per present findings single extraction frequency have maximum mean honey area of 668.4 inches2 followed by twice extracted colonies (568.6) with significant difference and regular extraction (449.0) gives least honey. Honey peaks were observed during mid February (837.8-916.8 inches2) which remains significantly higher than honey areas in January and in March. As far as colony growth was concerned colonies with two extractions have high total brood areas of 436.4 inches2 and similar trend was followed in case of larvae, pupae and egg. Effect on pollen stores gave a different picture in contrast of other parameters here colonies with regular extraction were observed with significantly high pollen stores (99.3 inches2) than single extracted colonies (83.7 inches2). For high honey production single extraction was recommended and if colony multiplication was also an aim than twice extraction is best option as per findings.

Different Parts

Nosema apis and Nosema ceranae are the two main microsporidian parasites causing nosematosis in the honey bee Apis mellifera. The aim of the present study is to investigate the presence of Nosema apis and Nosema ceranae in the area of Bulgaria. The 16S (SSU) rDNA gene region was chosen for analysis. A duplex PCR assay was performed on 108 honey bee samples from three different parts of the country (South, North and West Bulgaria). The results showed that the samples from the northern part of the country were with the highest prevalence (77.2%) for Nosema ceranae while those from the mountainous parts (the Rodopa Mountains, South Bulgaria) were with the lowest rate (13.9%). Infection with Nosema apis alone and co-infection N. apis/N. ceranae were not detected in any samples. These findings suggest that Nosema ceranae is the dominant species in the Bulgarian honey bee. It is not known when the introduction of Nosema ceranae in Bulgaria has occurred, but as in the rest of the world, this species has become the dominant one in Bulgarian Apis mellifera. In conclusion, this is the first report for molecular detection of Nosema infection of honey bee in Bulgaria. The results showed that N. ceranae is the main Nosema species in Bulgaria.

The Impact

AbstractForaging honey bees were offered various sucrose–herbicide solutions. Despite the visual attractiveness of the feeding dishes to foragers, six of seven herbicides significantly reduced the incidence of feeding and were judged to be olfactory and gustatory repellents. The most repellent herbicide was 2,4,5-T, which totally inhibited feeding at concentrations as tow as 1000 ppm. The next most repellent was 2,4-DB, followed by linuron, picloram, 2,4-D, and monuron. Paraquat was the only herbicide that did not exhibit marked repellency at concentrations up to 4000 ppm.The implications of these findings are discussed in terms of the impact of herbicide applications on honey bee foraging behaviour, brood development, pollination, and honey production.
