摘要: Aulacaspis yasumatsui Takagi continues to threaten the extinction of the endemic and endangered Cycas taitungensis in Taiwan. Failure to understand its population demographic parameters in detail will continue to hinder the success of pest management practices. An in-depth knowledge of the development, survival, and fecundity of A. yasumatsui under different environmental conditions is necessary to understand its’ population growth. The demography of A. yasumatsui was studied in the laboratory based on the age-stage, two-sex life table at 20, 23, 25, 28, and 31℃, 70% RH, and a photoperiod of 16:8 (L:D) h. The intrinsic rate of increase (r) under these temperatures was 0.0586, 0.0698, 0.0889, 0.1036, and 0.0783 d-1, respectively. The net reproductive rate (R0) was 46.27, 47.78, 69.50, 96.08, and 56.65 offsprings per individual and the mean generation time (T) was 65.60, 55.81, 47.82, 44.15, and 51.42 d, respectively. A. yasumatsui does well at warmer temperatures (25-28℃); however, its performance is disrupted at lower temperatures. This study provides insight on how to minimize growth and surpress the population of A. yasumatsui and conservation of Cy. taitungensis; new cycad reserves should be set up in cooler areas in Taiwan. In contrast to A. yasumatsui, Chilades pandava peripatria Hsu and its host plant Cycas taitungensis are both endemic species to Taiwan. Ch. pandava peripatria has a specific association with buds and soft leaves of cycad plants. The introduced species, Cy. revoluta, have prolonged budding periods and extensive auxiliary buds that extensively contribute to the outbreak of Ch. pandava peripatria. An in-depth knowledge of the development, survival and fecundity of Ch. pandava peripatria under different environmental conditions is necessary to understand the population growth of Ch. pandava peripatria. The demography of Ch. pandava peripatria was also studied based on the age-stage, two-sex life table at 20, 23, 25, 28, and 31℃, 70% RH, and a photoperiod of 16:8 (L:D) h under laboratory conditions. Ch. pandava peripatria completed its development under tested temperatures but did not produce offspring at 23℃. Due to the high egg mortality at 20℃, the data at this given temperature were excluded from this study. Under 25, 28 and 31℃ the intrinsic rate of increase (r) was 0.1846, 0.2919 and 0.1412 d-1, respectively. The net reproductive rate (R0) was 165.47, 262.32, and 56.68 offspring per individual and the mean generation time (T) was 27.72, 19.10, and 28.67 d, respectively. Our results indicated that Ch. pandava peripatria is highly adaptable to environments where temperature ranges from 25 to 31℃.
