摘  要：
【目的】明确劳氏粘虫Leucania loreyi (Duponchel)各虫态的发育起点温度和有效积温。【方法】本研究在光照培养箱中,测定劳氏粘虫分别在18、21、24、27、30℃下各虫态的发育历期,并运用有效积温法则计算出劳氏粘虫各虫态的发育起点温度和有效积温;采用Logisitic模型建立各虫态发育速率与温度的关系,进而求出各虫态的发育最适温度及适宜温区。【结果】劳氏粘虫各龄幼虫在18-30℃之间均能正常生长发育,发育历期随温度的升高而缩短。卵、幼虫、蛹、产卵前期和全世代的发育起点温度分别为11.83、13.89、14.20、﹣1.86和12.24℃,有效积温分别为52.55、254.53、118.15、121.89和542.26日·度。全世代的发育最适温度为20.71℃,发育适温区为12.65-28.78℃。【结论】根据广西代表地区气象资料,推算出劳氏粘虫在广西一年理论发生5.8-7.8代,与田间调查情况相符。

摘  要：
[Objectives] To study the developmental duration, developmental threshold temperature and effective accumulative temperature of Leucania loreyi(Duponchel)(Lepidoptera: Noctuidae). [Methods] The developmental duration of L. loreyi was determined under five constant temperatures(18, 21, 24, 27 and 30 ℃) in an incubator. The developmental threshold temperature(C) and effective accumulative temperature(K) of L. loreyi were determined using the effective accumulated temperature law. A logistic model was used to establish the relationship between temperature and developmental rates, and the optimum temperature, and optimum temperature range, calculated. [Results] L. loreyi developed normally within a temperature range of 18 to 30 ℃, and developmental duration decreased with increasing temperature. The threshold temperatures of eggs, larvae, pupae, and pre-oviposition stages, and that of an entire generation, were estimated to be 11.83, 13.89, 14.20,-1.86 and 12.24 ℃, respectively, and the corresponding effective accumulated temperatures were 52.55, 254.53, 118.15, 121.89 and 542.26 degree-days. The optimal temperature of an entire generation was 20.71 ℃, with a suitable temperature range of 12.65 to 28.78 ℃. [Conclusion] Based on meteorological data from representative areas in Guangxi, L. loreyi is estimated to have 5.8 to 7.8 generations annually in Guangxi. This is in accordance with field observations.
