title: [Effects of amino acids on the survival of heat-exposed Drosophila].
abstract: To investigate the effects of amino acids on the survival of heat-exposed Drosophila and to select the amino acids that can protect the Drosophila from heat exposure, Drosophila melanogaster were fed with basic culture in 25 degrees C. The male virgin Drosophilas were distinguished from female. Both male and female virgin Drosophilas were divided respectively to the trail groups and control group with randomization. The trail groups were fed with culture supplying different amino acids in 37.5 degrees C. After 10 hours, the dead insects were counted every two hours until all of them were dead. The mortality rates of heat-exposed Drosophilas that feed in the culture added with the glutamine, arginine, phenylalanine, tyrosine and glutamic acid were obviously higher than that of control. The glutamine, arginine, phenylalanine, tyrosine and glutamic acid might increase survival time of heat-exposed Drosophila, but a dose-response relationship was not observed.
