GENETICS AND BIOLOGY OF THE SAWFLY, ATHALIA-ROSAE (HYMENOPTERA) - REVIEW

Hymenopteran insects are a unique group of animals in which arrhenotok ous reproduction (haploid males develop from unfertilized eggs) is a r ule. Males produce sperm through a non-reductional maturation division . A sawfly species, Athalia rosae ruficornis Jakovlev (Tenthredinidae, Symphyta, Hymenoptera), has been introduced as a new experimental mat erial for studies on genetics and developmental biology. Basic feature s relating to the potential usefulness of the species in elucidating s ome of the important genetic and developmental biological problems are described.
