This algae has been recognized as a very important commercial product in the world today and as one of the most promising ones among the other microscopic algae due to its richness in polyunsaturated fatty acids, as well as in gamma-linolenic acid （GLA）, and in pigments including phycocyanin, myxoxanthophyll and zeaxanthin. Both immature and adult development stages ofS. tenuicosta have been studied under the temperature of 15±2℃. The development times for eggs, larval stages, including first, second, and third one, and for pupae as well as for adults were found to be 1.4, 1.0, 1.1, 1.1, 3.0 and 8.7 respectively. Some pest control practices ofS. tenuicosta on S. platensis have been also examined in this study.展开更多
