title: [Effects of temperature on Brontispa longissima population growth].
abstract: The study on the development, survival and reproduction of Brontispa longissima at 5 different temperature (16, 20, 24, 28, 32 degrees C) showed that the threshold temperature and effective accumulative temperature for the whole generations of Brontispa longissima were 11.08 degrees C and 966.22 degrees C, respectively, and 4-5 generations could occur in a year in Danzhou, Hainan Province. One generation had the highest survival rate (92.5%) at 28 degrees C, but failed to survive at 32 degrees C. Brontispa longissimna reared at 28 degrees C had the greatest intrinsic increasing rate (r(m) = 0.0260), finite increasing capacity (lamda = 1.0263), and population trend index (I = 50.8). The shortest mean generation time (123.1 d) and population doubling time (26.7 d) were obtained at 20 degrees C and 28 degrees C, respectively. The temperature from 24 degrees C to 28 degrees C was suitable for the development and reproduction of Brontispa longissima.
