不同温度下黄粉虫的实验种群生命表
Experimental Population Life Table of Tenebrio molitor at Different Temperatures
摘要
Abstract
In order to explore the effect of temperature on the population growth of Tenebrio molitor,the life table of laboratory population of T. Molitor was constructed at the following five temperatures (20 °C ,23 °C ,26 °C ,29 "C ,32 t). The result showed that the insect developmental rate increased with the temperature increasing. The longest duration of the generation was 97. 0 d at 20 °C ,and the shortest was 59. 9 d at 32 °C. The threshold temperatures required for egg,1 -13th instars and pupa were 5. 67, 5.49,4.04,4.74,5.15,4.79,4.74,5.03,4.85,4.44,4.39,5.13,4.56,4.41 and 7.44 °C,and the effective accumulated temperatures were 108. 16, 84. 79, 93. 29, 86. 43, 93. 10, 91. 34, 93. 52, 79. 88, 83. 08, 81. 39,94. 40,90. 88,91. 12,94. 02 and 128. 19 day-degrees,respectively. The life span of adult insect reduced with the temperature increasing. The longest life span was 51 d at 20 °C , while the shortest was 36 d at 32 "C. The maximum number of eggs laid per female was 237. 1 at 29 °C , while the least was 178. 2 at 20 °C. According to the experimental population life table of T. Molitor,its population trend index was high at 26 -29 °C ,and at 27. 8 °C ,it reached the theoretical maximum value of 86. 7. The results indicated that the appropriate temperature was 26 - 29 °C for T. Molitor propagation, and 27. 8 °C was more suitable for its growth and development.关键词
