1961-1962 - American Museum of Natural History

dition, the newly appointed director of the planetarium now under
construction in St. Louis, Missouri, spent two weeks here on
an orientation visit.
All members of the staff took active parts in the work of the
professional societies in which they have memberships. The
influence of the staff was also expressed through numerous
outside lectures, appearances on television and radio, and by
participation in panels and workshops for the National Science
Foundation, the American Association for the Advancement
of Science, and several other agencies of the museum, planetarium,
and astronomy professions.
DEPARTMENT OF ENTOMOLOGY
Jerome G. Rozen, Jr., Chairman
The new direction that the Department of Entomology is
gradually taking was evidenced this year by considerably increased
activity in three areas-research productivity, curatorial
accomplishments, aiid exhibition.
Dr. Rozen, working under a National Science Foundation
grant, continued the biosystematic study of the parasitic bees
in the genus Oreopasites. All species in this genus are obligatory
parasites in the nests of the non-social bee genus Nomadopsis.
Having previously completed the initial taxonomic
work, Dr. Rozen devoted his attention this year to a study of
the behavior and biology of the various species. During three
field trips to the western and southwestern United States (in
spring, summer, and early fall), he worked out comparative
life histories and host associations, performed nutritional
experiments in order to determine the nature of the intraspecific
variation in these bees, and made extensive collections which
included over-winter immature stages of eight different forms.
In addition, Dr. Rozen brought to completion an anatomical
and systematic study of the larvae of the beetle family Nitidulidae,
an investigation that was initiated by the late Dr.
