TL;DR: Africanized honey bees were first detected in California in October 1994 and since then, they have established a foothold in the Imperial Valley and have spread toward San Diego and into Palm Springs, however, their spread has been much slower than originally expected.
Abstract: Africanized honey bees were first detected in California in October 1994. Since then, they have established a foothold in the Imperial Valley and have spread toward San Diego and into Palm Springs. However, their spread has been much slower than originally expected. What has slowed them? The best guess is Varroa jacobsoni, an exotic ectoparasite of honey bees recently introduced into North America. The effects of varroa on Africanized honey bees may be both a blessing and a curse; the latter is especially true if Africanized bees become resistant to varroa and commercial honey bees do not.

TL;DR: In this paper, it is shown that the larvae of the Varroa mite (Varroatose) can hatch at the same time as the bees and the larvae can be treated by biotechnological means without damaging residues in honey and wax.
Abstract: The bees require 35@C in order for their nest to hatch. Since, however, the bees faithfully pursue tasks in order to preserve their species, this primarily also means consumption of food and great activity. On the other hand, the bee is being done great harm by the worldwide occurrence of the Varroa mite (Varroatose). This parasite lays its offspring-bearing eggs in the brood cells of the bees and develops with the bee in the concealed nest so that when the young bee hatches the Varroa parasite also hatches at the same time. The bees have no opportunity to get rid of the parasite themselves so that without external aid whole bee populations die. Elimination would be possible if there were no honey and wax which become toxic and are hence unsuitable for human consumption. By virtue of the device of this invention it is possible to allow concealed brood combs of the bees to hatch in the breeding and treatment system by keeping to rational technology, observing a good latent period and taking into consideration the nascent life and the division of labour between nature, bee and development. As the Varroa mite hatches at the same time as the bees hatch it is possible to use techniques in order to carry out treatment in the system according to the invention by biotechnological means - thermally and naturally, without obtaining damaging residues in the honey and wax. So that the bees are not born into a technical world... Original abstract incomplete.

TL;DR: There is a need for constant monitoring of bee pests and diseases in honeybee colonies in the country for early detection and to provide data on the status of bee health, and all stakeholders in the beekeeping value chain should be enlightened on their role in pest and disease transmission.
Abstract: Varroa mite (Varroa destructor Anderson and Trueman) is a major global threat to the western honey bee (Apis mellifera L.). The ectoparasite has been implicated in the spread of honeybee viruses. Beekeeping plays a major role in transmission of the mite. The study aimed at assessing levels of Varroa infestation, bee viruses and bacteria incidences in domesticated honeybee colonies. Samples of adult honey bees, bee brood and Varroa mites were collected from Baringo, Narok, Kwale, Magarini, Voi, Ijara, Busia and Siaya in Kenya. Ten hives in each site were inspected for the presence of Varroa mites on adult bees using the icing sugar technique and forceps in sealed brood cells. The number of mites observed were recorded per site. Ribonucleic acid was extracted from the mites, brood and adult bees and a polymerase chain reaction was performed to detect the black queen cell virus. Pooled RNA samples of brood and adult bees were used in next generation sequencing on a 454 GS FLX platform to detect bee v...
