| 中文摘要: |
| 为探明毛健夜蛾昼夜行为节律，在光周期L∥D=12 h∥12 h、恒温28 ℃下，较系统地观察了其化蛹、羽化、交配、产卵及卵孵化行为。结果表明：（1）化蛹主要发生在光期，但无明显的化蛹高峰期；（2）羽化也主要发生在光期，主高〖JP2〗峰期在10:00-11:00；（3）交配主要发生在暗期，两个明显的主要交配高峰期分别为19:00-20:00和0:00-1:00；（4）产卵也主要发生在暗期，在熄灯后的4 h内和光开启前的4 h内产卵数最多；（5）卵孵化主要发生在0:00-〖JP〗12:00，孵化的高峰期为8:00-10:00。这些结果表明，毛健夜蛾的化蛹、羽化、交配、产卵和孵化具有明显的昼夜节律性。 |
| 英文摘要: |
| To understand the circadian rhythm in Brithys crini (Fabricius), the pupation, eclosion, mating, egg laying and hatching were systematically observed under the photoperiod of L∥D=12∥12 at 28 ℃. The results showed that (1) pupation generally occurred in photophase, but there was no obvious pupation peak in females and males; (2) eclosion generally occurred in photophase and eclosion peak occurred at 10:00-11:00; (3) mating generally occurred in scotophase. Two distinct mating peaks occurred at 19:00-20:00 and 0:00-1:00, respectively; (4) eggs were laid within 4 h after lights out and 4 h before lights on; (5) hatching occurred in 0:00-12:00, and hatching peaks occurred at 8:00-10:00. These results suggested that pupation, eclosion, mating, egg laying, and hatching in B. crini had a distinct circadian rhythm. |
