24-Hour Varroa Heat Study — Le Conte, Arnold and Desenfant (1990)

Reviewed notes and corrections

The cited 1990 work concerns temperature and humidity experiments with parasitized brood. The table in the sheet refers to sampled mother mites and brood under those experimental conditions; it does not demonstrate colony-wide mite elimination or queen safety. Observed brood losses must be reported alongside mite mortality. Refer to the original paper for its table values, methods and statistical interpretation.
