摘要

玉米象鼻虫玉米象(Sitophilus zeamais, Motschulsky)是一种严重的害虫,影响多种谷类作物,如玉米、水稻、豆类和其他储存的干燥谷物。由于玉米象鼻虫雌虫通过咀嚼进入谷粒后可以在其一生中长时间产卵,因此玉米象鼻虫的大部分发育阶段,如卵、幼虫和蛹,都可以在储存的玉米谷粒中找到。玉米象鼻虫在长粒稻上的实验表明,玉米象鼻虫雌虫在羽化交配后10天开始产卵,产卵期为145天。平均每只玉米螟产卵38.67枚,其中62.81%产于前7 ~ 8周,其余37.19%产于145 d后半期,55.07%产于55 ~ 95天。利用三次多项式对玉米玉米玉米的产蛋模式进行建模,描述了第15、35、75、95和105天的最大产蛋率。

Analysis of reproductive traits and laying egg rhythm of maize weevil sitophilus zeamais (motschulsky)
The maize weevil, Sitophilus zeamais (Motschulsky), is a serious pest affecting a wide range of cereal crops, such as maize, rice, beans and other stored dried grains. As a S. zeamais female can keep laying eggs for a long time throughout its life after chewing its way into the grains, most development stages of the maize weevil, such as eggs, larvae and pupae, can always be found in stored maize grains. Our experiment with S.  zeamais on long grain rice showed that 10 days after eclosion and mating, maize weevil females started laying eggs for a period of 145 days. On average, a S.  zeamais female laid 38.67 eggs, of which, up to 62.81% were laid in the first 7–8 weeks (with the remaining 37.19% in the latter half of the 145 day period), and 55.07%  were laid within day 55–95. The egg laying pattern of S. zeamais was modeled using cubic polynomials, which described the maximum percentages of eggs laid at day 15, 35, 75, 95 and 105.
