摘要: 为明确玉米象成虫的产卵节律,给综合治理玉米象提供理论支撑,采用传统的生物学测定方法,测定了玉米象成虫在5 种储粮中的产卵节律。结果表明:在(27±1)℃条件下,玉米象雌成虫在糯玉米、薏米、普通玉米、高粱和小麦中的产卵历期分别为137.14、122.86、85.71、80.00、51.43 天。玉米象单头雌成虫在糯玉米、薏米、普通玉米、高粱和小麦中的产卵量分别为45.65、45.34、21.34、49.20、33.97粒。玉米象雌虫无明显的产卵前期,羽化后当天即可产卵,但不同储粮中玉米象雌成虫的产卵节律不同。在高粱和小麦中,雌成虫的产卵高峰期出现在羽化后10~20 天,在普通玉米中出现在羽化后的20~30 天,而薏米组中的则出现在羽化后40~50 天,糯玉米组为羽化后70~80 天。综合试验结果认为:玉米象的繁殖力和产卵节律受储粮种类的影响。

Abstract: In order to provide theoretical support for the comprehensive control of Sitophilus zeamais Motschulsky, the oviposition rhythm of S. zeamais in waxy maize, coix seed, common corn, sorghum and wheat was studied by using the traditional biological method under the temperature of (27±1)℃. The results showed that the oviposition duration of S. zeamais in waxy maize, coix seed, common corn, sorghum and wheat was 137.14, 122.86, 85.71, 80.00 and 51.43 days, respectively. And a female adult could lay 45.65, 45.34, 21.34, 49.20 and 33.97 eggs in the above 5 kinds of grains, respectively. No obvious pre-oviposition period was found, the females could lay eggs on the same day of eclosion, but their oviposition rhythm showed differences in different kinds of grains. The oviposition peaks appeared in 10-20 days in sorghum and wheat, 20-30 days in common corn, 40-50 days in coix seed and 70-80 days in waxy maize after eclosion, respectively. In conclusion, the fertility and oviposition rhythm were affected by different kinds of grains.
