    Description

    The effect of starvation on the feeding rate of larval Chaoborus (Diptera. Chaoboridae) was investigated using Daphnia rosea as prey. The starvation period varied from 12 h to 22 days. The starved Chaoborus were individually incubated with 10 Daphnia under controlled light and temperature conditions. Observations were made on prey mortality every 2 h for the first 12 h and once after 24 h. Feeding rates gradually increased to a maximum between 7-11 days of starvation. After this period, feeding rates declined to previous low levels. Generally, feeding rates were significantly higher during the first 2 - 4 h of feeding. Thereafter, feeding rates were lower and exhibited no consistent patterns with length of feeding time.
