| 摘 要： | 作者对复苏后玉米螟的饮水作用研究表明，玉米螟幼虫摄取水分的过程是通过口器主动饮水，饮水后促进虫体重量增加、死亡率降低和提高化蛹率。在一定范围内，饮水量取决于饮水时间的长短。死亡率（Ｄ）和化蛹率（Ｐ）与饮水时间（ｔ）的关系为：Ｄ＝７０．５１８０ｔ＾－０．３５７６（ｒ＝０．９１８８＾＊＊）和Ｐ＝３．５８９９＋１．０５１０ｌｇｔ（ｒ＝０．９５３５＾＊＊）。饮水量（Ｘ）与化蛹率的关系：Ｐ＝０．８４０８Ｘ＾

| Abstract: | The results of indoor investigations on the water intake behavior of Asian corn borer (ACB) Ostrinia furnacalis (Guenee) showed that the resuscitative larvae of overwintering generation sucked water by mouth. After water sucking, the larval body weight was increased, the larval mortality was decreased and the pupation rate was enhanced. In a certain range, the water intake of larva depended on the time it spended to drink. The simulation equations of the relationships between larval mortality (D) and drinking time (t), pupation rate (P) and drinking time, and pupation rate and water intake (X) were: D= 70. 5180 t-0.3576 (r = 3. 9188**);P = 3. 5899 1. 0510 lg t (r = 0. 9535* * ); and P = 0. 8408 X1.'042(r = 0. 8836* ); respectively. Generally, the water intake of larva was nearly a half of its body weight. Under 26 C condition, the water intake occurred within 20 - 30 days since the resuscitation of ACB larvae was most beneficial to their pupation. |
