On the developmental stages of the beet fly, Pegomyia hyoscyami Panz. in Egypt (Diptera: Anthomyidae). [link]Paper  abstract   bibtex   
In this account of further studies on Pegomya mixta Villen. (hyoscyami auct.) on sugar-beet in Egypt [see preceding abstract], the authors describe the egg, larva and pupa of the Anthomyiid and give details of the duration of the immature stages in the laboratory. The egg stage averaged about two days in June and 6.3 days in January. When the fly was reared at constant temperatures, maximum numbers of eggs hatched (100%) at 20 deg C. The three larval instars together lasted for averages of about 19.6 days at 16 deg C and 10.6 days at 20 deg C. None of the larvae kept at 30 deg C completed their development. The larvae mine in the leaves, and the nature of the mines and the tissues eaten by the larvae are described. Red beet was preferred to sugar-beet, and sugar-beet to spinach. The full-fed larvae leave their mines and pupate in the soil. The pupal stage averaged about 12.8 days in June and 24 days in January. Under controlled temperatures it averaged about 12.2 days at 30 deg C and 100.5 days at 8 deg C. Pupae kept at 35 deg C died without giving rise to adults.
