The intake and utilization of dietary nitrogen by the cotton bollworm Heliothis armigera (Hubner)

, : The intake and utilization of dietary nitrogen by the cotton bollworm Heliothis armigera (Hubner). Acta Entomologica Sinica, 311: 1-7

The intake and utilization of dietary nitrogen by the noctuid cotton pest Heliothis armigera were studied by rearing larvae from the 2nd instar on either young cotton leaves or bolls or on lucerne-wheat germ artificial diet at 25 degrees C. Analysis of nitrogen in the faeces showed that larvae in the later stages had lower rates of nitrogen intake and utilization than 2nd- and 3rd-instar larvae.
