220.127.116.11. Sex determination of pupae
The sex of pupal SHBs can be determined visually without the need to manipulate the individual (Fig. 10).
- Observe the ventral side of the distal section of the abdomen.
- Look for two bulbous projections on this location.
(Fig. 10a), it is a female pupa. These projections are absent in male pupae
Fig. 10. Sexing pupal small hive beetles. A. and C. show the tip of the ventral side of the abdomen of a female small hive beetle. The two bulbous protrusions are circled. B. and D. show the tip of the ventral abdomen of a male small hive beetle. The bulbous protrusions are absent from the circled area. A. and B. are shown with enhanced contrast to highlight the genital area. Sketches: Kay Weigel (University of Florida; photos Lyle Buss.
