Abstract
A comparative study was made of the consumption, digestion and utilization of cabbage by the 3rd‐, 4th‐ and 5th‐instar hoppers of Schistocerca gregaria and Locusta migratoria. The rate of consumption (C.L.) and the digestibility (except in 3rd instar) of cabbage by Locusta hoppers were greater than by Schistocerca hoppers. However, weight increase, growth rate (except in 4th instar), gross and net efficiency of food utilization were found to be significantly higher in Schistocerca hoppers than in Locusta hoppers. The total live weight gain of Schistocerca hoppers for a period of 18 days was about twice that in Locusta hoppers. Slower growth rate and lesser efficiency of food utilization by Locusta hoppers were considered to be due to nutrient imbalance of cabbage for Locusta. ZUSAMMENFASSUNG AUFNAHME, VERDAUUNG UND AUSNUTZUNG DER NAHRUNG DURCH HEUSCHRECKEN Es wurde eine vergleichende Untersuchung des Verbrauchs, der Verdauung und der Ausnutzung von Kohl durch das 3., 4. und 5. Larvenstadium von Schistocerca gregaria und Locusta migratoria durchgeführt. Die Verbrauchsrate (C.I.) und die Verdaulichkeit von Kohl war (mit Ausnahme des 3. Larvenstadiums) bei Locusta ‐Larven grüßer als bei Schistocerca ‐Larven. Jedoch erwiesen sich Gewichtszunahme, Wachstumsrate (mit Ausnahme des 4. Larvenstadiums), Brutto‐ und Netto‐Wirkungsgrad der Nahrungsverwertung bei Schistocerca ‐Larven als signifikant höher als bei denen von Locusta. Die gesamte Lebendgewichtszunahme von Schistocerca ‐Larven war über einen Zeitraum von 18 Tagen etwa zweimal so groß wie bei Locusta ‐Larven. Die langsamere Wachstumsrate und der geringere Wirkungsgrad der Nahrungsausnutzung durch die Locusta ‐Larven werden als Folge der nutritiven Unausgeglichenheit von Kohl für Locusta angesehen.
