This study deals with the effect of five constant temperatures (20, 25, 30, 32.5 and 35°C) on development, longevity, fecundity and survival of Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae) infesting white soft wheat flour. Temperature showed profound effects on immature development, and adult longevity. Egg hatching at 20°C took 13.58 d that is decreased to 3.26 d at 35°C. Larval developmental time decreased by 40.47 d from 20 to 32.5°C with no significant difference between 32.5 and 35°C. Pupal developmental time was shortened from 17.18 d at 20°C to 4.48 d at 35°C, while no significant differences were observed in pupal development between 32.5 and 35°C. Female and male longevity increased by 164.12 and 156.42 d, respectively when temperature was increased from 20 to 25°C followed by a decrease in longevity for both sexes at 35°C. Female fecundity was lowest at 20°C (1.09 eggs/female) and highest at 25°C (64.82 eggs/female). Using the non-linear Briere model, the lower developmental threshold of O. surinamensis was estimated as 16.9°C, the upper threshold as 40.7°C, and the temperature for maximum developmental rate close to 31.3°C. Ikemoto & Takai linear model indicated that 313.3 degree-d above a threshold of 16.3°C were needed for the completion of immature development. Temperature-dependent egg to adult survival of O. surinamensis was described by an extreme value equation, indicating that survival decreased at both ends of the temperature range, but higher temperatures had more detrimental impact on immature survival than lower temperatures. According to the estimated parameters, the highest immature survival (93.6%) was estimated to occur at 28.3°C. The highest value of the net reproductive rate (20.10 females/female), was observed at 25°C. We expect these results to be useful for the prediction of the phenology and potential expansion of O. surinamensis, through the implementation of temperature-driven models, leading to accurate management strategies.

线性和非线性模型来解释温度对suryamus(L.)的生活史特征的影响

这项研究研究了五个恒温温度(20、25、30、32.5和35°C)对白色软质小麦面粉感染的Oryzaephilus surinamensis(L。)(鞘翅目:Silvanidae)的发育,寿命,繁殖力和存活的影响。温度对未成熟发育和成年寿命显示出深远的影响。鸡蛋在20°C孵化需要13.58 d,而在35°C则减少到3.26 d。从20℃到32.5℃,幼虫的发育时间减少了40.47 d,在32.5℃和35℃之间没有显着差异。pal的发育时间从20°C时的17.18 d缩短到35°C时的4.48 d,而3的发育在32.5和35°C之间没有观察到显着差异。当温度从20升高到25°C时,女性和男性的寿命分别增加了164.12和156.42 d,然后在35°C时男女的寿命都降低了。雌性繁殖力在20°C时最低(1.09个鸡蛋/雌性),在25°C时最高(64.82个鸡蛋/雌性)。使用非线性Briere模型,苏里南稻的最低发育阈值为16.9°C,最高阈值为40.7°C,最大发育温度约为31.3°C。Ikemoto&Takai线性模型表明,完成不成熟发育需要高于16.3°C的阈值313.3度。用极值方程描述了温度依赖的卵对苏里南稻成虫的存活,这表明在温度范围的两端存活率均下降,但较高的温度比较低的温度对未成熟的存活率具有更大的不利影响。根据估计的参数,最高的未成熟存活率(93.6%)估计在28.3°C发生。在25°C时观察到最高净生殖率(20.10雌性/雌性)。我们希望这些结果通过实施温度驱动的模型,从而导致精确的管理策略,对预测苏里南稻的物候和潜在的扩展有用。
