    Description / Table of Contents: Zusammenfassung Nahrungswahlversuche bestätigen die Existenz einer induzierten Nahrungspräferenz beiCarausius und zwar sowohl in Doppel- als auch in Vielfachwahlversuchen. Die Präferenz wird offenbar im Alter von 10 bis 20 Tagen induziert und bleibt für den Rest des Lebens sehr ausgeprägt. Ein statistischer Uebereinstimmungstest weist darauf hin, dass ältere Tiere weniger flexibel in der Nahrungswahl sind. Präferenzen werden durch das Fressen an einer zweiten Nahrungspflanze rasch geändert. Während der ganzen Untersuchung waren altersbedingte Unterschiede feststellbar.
    Notes: Abstract Feeding preference tests confirm the existence of an induced food plant preference inCarausius morosus (Br.) in dual and multiple choice tests. The preference appears to be induced between the ages of 10 and 20 days and remains at a very high level for the remainder of the insect's life span. A statistical test of concordance indicates that there is less flexibility in the food plant choice of older animals. Preferences can be rapidly modified through feeding on a second food plant and age differences are apparent throughout the study.

    Description: Bottom line results were made of a three-phase study to determine the feasibility of designing, building, and operating, and maintaining an air-launched high performance aircraft capable of cruising at speeds up to Mach 8 for short durations. The results show that Lockalloy heat-sink structure affords the capability for a 'work-horse' vehicle which can serve as an excellent platform for this research. It was further concluded that the performance of a blended wing body configuration surpassed that of a lifting body design for typical X-24C missions. The cost of a two vehicle program, less engines, B-52 modification and contractor support after delivery, can be kept within $70M (in Jan. 1976 dollars).
