* Oestrus detection is important, for although the queen is an '''induced ovulator''' (thus [[The_Ovary_-_Ovulation_- Anatomy & Physiology|'''ovulation''']] will not be missed), the LH response to mating decreases with each day of oestrus and [[The_Ovary_-_Follicles_- Anatomy & Physiology|'''follicles''']] ultimately regress.
