The transmission of deformed wing virus between honeybees (Apis mellifera L.) by the ectoparasitic mite varroa jacobsoni Oud
Under field conditions, Varroa jacobsoni were shown to be highly effective vectors of deformed wing virus (DWV) between bees. Adult female mites obtained from honeybee pupae naturally infected with DWV contained virus titers many times in excess of those found in their hosts and, beyond that, which might be expected from a concentration effect. It is therefore possible that DWV may be capable o...
متن کاملDevelopment of Varroa jacobsoni in colonies of Apis mellifera capensis and Apis mellifera carnica
Honey bee colonies (Apis mellifera carnical, infested with Varroa jacobsonl were de-queened and divided into 2 subunits. Each pair of subunits were requeened with an inseminated A m capensis and A m carnica queen. The development of the mite population was monitored by determining the number of mites in samples of brood, and worker bees, and lhe number of dead mites on the bottom board of the h...
متن کاملBehavioral defenses of honey bees against Varroa jacobsoni Oud . Otto
Two behaviors of honey bees, hygienic behavior and grooming, are mechanisms of defense against brood diseases and parasitic mites. Studies have shown that Apis mellifera colonies remove worker brood infested with Varroa jacobsoni mites from the nest (hygienic behavior), and groom the mites off other adult bees, but to a limited extent compared to the original host of V. jacobsoni, A. cerana. Re...
متن کاملSoftwarezuverlässigkeitsbewertung auf Basis von Betriebsprofiltreue und Schnittstellenüberdeckung
Zusammenfassung Dieser Artikel stellt einen neuen Ansatz zur Softwarezuverlässigkeitsbewertung vor, der über die Betriebstreue der auszuwertenden Testfälle hinaus auch eine hohe Überdeckung der Komponentenschnittstellen sicherstellt. Der Erfüllungsgrad der zugrunde liegenden Bedingungen hinsichtlich Profiltreue, Testdatenunabhängigkeit und Interaktionsüberdeckung wird durch geeignete Metriken e...
متن کاملA population model for the ectoparasitic mite Varroa jacobsoni in honey bee (Apis mellifera) colonies
The ectoparasitic mite Varroa jacobsoni Oud. presently poses one of the most serious problems faced by keepers of honeybees Apis mellifera L. To help understand why the mite has become such a serious problem a population dynamics model using recently published data has been constructed. The simulation model has been built by linking together various aspects of the mites’ biology using computer ...
