甜菜夜蛾Spodoptera exigua（Hubner）在15 - 38 ℃的8个恒温条件下以人工饲料、平滑的苋（Amaranthus hybridus）或棉花（Gossypium hirsutum L.）饲养。发育率，存活率，蛹的重量，和不同的饮食之间的视距数。针对每种饲料中甜菜夜蛾卵、每个虫期以及整个幼虫和蛹期的发育速率开发了线性和非线性模型。估计卵的发育阈值为12.42 +/- 1.58 ℃。幼虫发育率下降，在38摄氏度的所有饮食。蛹的发育率下降，在36摄氏度的所有饮食。所有饲料中所有发育类别的发育阈值相似，平均为13.6 +/- 0.46 ℃。在高温和低温下，所有饮食的视距的数量增加。幼虫需要更长的时间来发展，达到一个较低的蛹重量，并需要更大数量的视距棉花比人工饲料或猪草。
The beet armyworm, Spodoptera exigua (Hubner), was reared at eight constant temperatures ranging from 15 to 38-degrees-C on an artificial diet, smooth pigweed, Amaranthus hybridus, or cotton, Gossypium hirsutum L. Developmental rates, survival, pupal weights, and number of stadia varied among diets. Both linear and nonlinear models were developed for the developmental rate of beet armyworm eggs, each stadium, and the entire larval and pupal stages on each diet. A developmental threshold of 12.42 +/- 1.58-degrees-C was estimated for eggs. Larval developmental rates declined at 38-degrees-C on all diets. Pupal developmental rates declined at 36-degrees-C on all diets. Developmental thresholds were similar for all developmental categories on all diets and averaged 13.6 +/- 0.46-degrees-C. The number of stadia increased at both high and low temperatures on all diets. Larvae took longer to develop, attained a lower pupal weight, and required a greater number of stadia on cotton than on artificial diet or pigweed.
