柑橘大实蝇交配和产卵习性的研究

Mating and Oviposition Behaviours of Bactrocera(Tetradacus) minax

本文在室内研究了柑橘大实蝇Bactrocera（Tetradacus）minax的交配和产卵习性。观察结果表明,该虫的交配前期17~25 d,平均19.33±3.54 d;交配期12~47 d,平均34.00±13.40 d;交配持续时间最短7 min,最长为95 min,平均时长为44.42±22.56 min。该虫的产卵前期28~37 d,平均33.13±7.43 d;产卵期19~41 d,平均24.80±9.58 d;产卵行为中的定位、穿刺、排卵的持续时间分别为：17.45±9.62 min、6.42±2.64 min、23.29±11.94 min。

Currently,the mating and oviposition behaviors of Bactrocera（ Tetradacus） minax were investigated in laboratory. The results showed that the pre- copulation period ranged from 17 to 25 days,with an average of 19. 33 ± 3. 54 days. The whole period of mating lasted for 12- 47 days,with an average of 34. 00 ± 13. 40 days. The process of mating behavior lasted for 7- 95 minutes,with an average of 44. 42 ± 22. 56 minutes.The pre- oviposition period lasted for 28- 37 days,with an average of 33. 13 ± 7. 43 days. The whole period of oviposition lasted for 19- 41 days,with an average of 24. 80 ± 9. 58 days. During the oviposition period,three behaviors including host searching,puncturing and ovipositing lasted for 17. 45 ± 9. 62 minutes,6. 42± 2. 64 minutes and 23. 29 ± 11. 94 minutes,respectively.
