Held every April, Sugar Shake Month aims to:
Varroa mites (Varroa destructor and V. jacobsoni) infest honey bees (Apis mellifera) in every major beekeeping area of the world, except Australia. The mites are tiny reddish brown external parasites of honey bees. They mainly feed and reproduce on larvae and pupae in the brood. Mites also feed off adult bees, transmitting viruses, weakening the colony and resulting in death of the hive.
Braula fly or bee lice (Braula coeca) live in honeybee colonies. The larval stage burrows under the cappings of honey comb, reducing its commercial value. Brauly fly is present in Tasmania and has not been detected on mainland Australia.
The tropilaelaps mite (Tropilaelaps clareae and T. mercedesae) is a parasite of honey bees. They are reddish in colour and about half the size of varroa mites. They mostly reproduce in the brood but some are found on adult bees. Symptoms include deformed pupae and adults (stunting, damaged wings/legs/ abdomens) and colony decline.
Hives can be inspected using the sugar shake test. This method relies on the sugar particles separating the mites from the bee. This technique does not kill the bees.
Early reporting of an exotic bee pest like varroa as is one of the most important factors in eradicating any incursion. Negative test results are also important in proving that Australia remains free of pests like varroa mite.
During Sugar Shake Month, all test results reported to DPI will go into a draw for a prize. Don’t miss your chance to win!
Sugar shake test results will be used to support Australia’s export trade of queen and packaged bees.
If you think you have found an exotic pest like varroa mite, you must notify NSW DPI immediately. You can report suspected exotic pests by calling the Exotic Plant Pest Hotline 1800 084 881
