Abstract
Abstract The influence of four cruciferous host plants viz: Cabbage, cauliflower, turnip and radish on rate of development, mortality, weight of immatures, fecundity and number of annual generations of Trichoplusia ni was experimentally investigated. Host plants exerted no effect on the number of annual generations. Cabbage was the most favourable host plant. Larval development was accelerated when fed on cabbage leaves and somewhat retarded on radish. Larval diet also had enormous effect on pupal duration, generation period and adult longevity. Females fed as larvae on cabbage laid the highest number of fertile eggs. Weights of the different stages were the heaviest when their larvae were fed on cabbage or cauliflower leaves. Zusammenfassung Über den Einfluß der Wirtspflanzenart auf die Entwicklung und Genemtionszahl der Kohleule, Trichoplusia ni (Hb.) in Ägypten Es wurde der Einfluß von 4 Wirtspflanzenarten aus der Familie Cruciferae (Weißkohl, Blumenkohl, Rettich und Radieschen) auf Entwicklungsrate, Sterblichkeit, Larven‐ und Puppengewicht, Fekundität sowie Zahl jährlicher Generationen von Trichoplusia ni untersucht. Die Wirtspflanze zeigte keinen Einfluß auf die Generationszahl. Bevorzugte Pflanzenart war der Weißkohl. Die Raupenentwicklung wurde bei Fraß an Weißkohl beschleunigt, bei Fraß an Radieschen etwas verlangsamt. Die Raupennahrung zeigte starke Auswirkungen auf die Puppendauer, Generationsperiode und Falter‐Lebensdauer. Weibliche Falter, hervorgegangen aus Raupen, die an Weißkohl fraßen, legten die höchste Zahl befruchteter Eier ab. Die Gewichte der verschiedenen Stadien waren nach Fraß der Raupen an Weißkohl oder Blumenkohl am höchsten.
