Consumption, digestion and utilization of various grasses by fifth-instar larvae and adults of the migratory locust
Entomologia Experimentalis et Applicata 19 (2), 130-138
Abstract: Food consumption, digestion and utilisation were estimated in 5th instar larvae and adults of Locusta migratoria by measuring the weight of food ingested, the weight of faeces produced, and the increase in body weight. Diets of either rye, perennial rye-grass, cocksfoot, water meadow-grass, or reed-grass were provided. Neither the general shape of the growth curve nor the length of the developmental period were influenced by these diets. Differences in the amounts of food consumed and digested according to the diet are discussed. A greater digestive capacity in the larvae was apparent. This digestive capacity remains constant within each developmental period, although its absolute value may differ, and it is dependent on the type of food offered. The efficiency of conversion of ingested food and digested food to body substance is greater for water meadow-grass and, especially, rye than for the other grasses.
