>Varroa mites are everywhere, Tropilaelaps are not. Obviously there is a reason for this.
It's just a matter of time until the industry imports Tropilaelaps to Europe and North America. Their leap from the giants in Asia to A. mellifera was a pivotal migratory step. Tropilaelaps can co-exist with varroa in the same colony, and their biology doesn't restrict their survival in our climate. Tropilaelaps is also surviving in colder Chinese climates.
The emerald ash borer and spotted lantern fly took their time getting here, as did bees from Africa -until we brought them here. In our state, the pest and parasite strategy is already in place. It will involve an initial attempt at containment, which in time will fail, followed by observation and a treatment protocol.
> Tropilaelaps mites present a greater threat than the infamous Varroa destructor to A. mellifera. Until now, there is no report concerning the Tropilaelaps mites found in European apiculture industry. With the frequent transfer of commercial bee colonies, the bee trade globalization, the natural proliferation of bees, and the gradual warming of the global climate, it may be only a matter of time until Tropilaelaps spread outside of Asia to cause devastating effects on apiculture industry in Europe and North America [6].
