    Hello, thank you very much for these notes. They are very useful. I think I have found a minor inconsistency in the numbers given for stages in the Varroa life-cycle .. it is not much, but makes a difference to the details of the number of mites that can mature on a worker brood: I’ve written up the details here: http://martinjuckes.blogspot.co.uk/2017/12/p-margin-bottom-0.html . It concerns the time taken for a Varroa mite to reach maturity.

      Martin,

      Thank you for your comment.

      I am not sure where you see the specific days in the notes.

      The notes reference the NBU Varroa document which are in line with your numbers.

      I will revisit the life cycle page and try and make it more specific using your references if that is OK.

      Regards

      Sean

        Sean, thanks. In the diagram reproduced on page 16 it says, in paragraph 5, mistakenly I think: “Time from egg to adult for males is 5-6 days, and for females 7-8 days”. I noticed that this is not consistent with the figure on page 15 which has the 2nd egg hatching at day 11.5 and producing a mature adult 6.5 days later. The main text is not explicit on these numbers, so I looked for other literature. Please use anything you find useful,

        regards,
        Martin

    Dear Sean,

    I’m afraid I’m having more problems with numbers in the module 3 study notes.

    I think there is a problem with the numbers given for the duration of different stages of the wax moth life cycle. The study notes say 5-8 days for the eggs, 6-7 weeks for he larvae, and 6 to 55 days as a pupa. Wikipedia says 7 to 22 days for eggs, 1 to 6 months for larvae, 1 to 9 weeks as pupae. For a third opinion I’ve looked at the Australian BeeAware site which gives 3 to 35 days for eggs, 20 days to 5 months for larvae, and 3 days to two months for pupae. Finally, Morse and Flotum (Honey Bee Pests, Predators and Diseases) give the total life cycle of the Greater Wax Moth as being from 4 weeks to 6 months in duration. There are quite a lot of different opinions here … but wikipedia, BeeAware and Morse and Flotum all suggest a somewhat longer total life time of 6 months or more when development is slow, and a significantly shorter larval stage when development is fast, of 3 to 4 weeks (or less for Morse and Flotum).

    I’m not sure what the best approach would be here, but I’m hoping that it will be acceptable to cite Morse and Flotum in the exam, along with some rough figures for individual stages of development,

    regards,
    Martin
