Trevor wrote: Can you give a reference for this statement to show that larger bees (read larvae) have a different JGH production than smaller bees (read larvae). Dee responds with: "These researchers were able to show that mite reproduction hinges on the physiological condition of the infested honey bee larvae. Thus, the juvenile hormone titer in the blood of the honey bee prepupa dictates whether the female mite initiates egg laying after the first blood meal." Pardon me, but physiological condition does not equal size. Your reference does not address the question that Trevor asked. pb -- Visit www.honeybeeworld.com/bee-l for rules, FAQ and other info ---
