| 摘 要： | 通过实地调查,观察并分析了柑橘大实蝇Bactrocera(Tetradacus)minax(Enderlein)成虫在柑橘园及其附近杂树林的觅食产卵活动规律。结果表明:在柑橘大实蝇羽化开始到羽化盛期,以柑橘园与杂树林交界区域的成虫密度最大,并于6月11日达到高峰,在Z3监测带(杂树林与基准带相距5m)每个诱捕罐的诱捕虫数为(24.0±5.6)头,J1监测带(柑橘园与基准带相距5m)为(74.7±21.9)头,显著高于其他监测带;羽化盛期60%以上的柑橘大实蝇成虫在Z3监测带和J1监测带的交界带内活动;羽化盛期过后的产卵期,诱捕虫数明显下降,且柑橘大实蝇在柑橘园中的分布比较均匀,Z1监测带(杂树林与基准带相距100m)没有诱到成虫,其他不同监测带的诱捕虫数也没有显著差异;柑橘大实蝇产卵时对果实的不同部位具有明显的选择偏好性,其中果腰处的产卵痕数量分别是果蒂和果脐处的7倍和4倍,而且果实阴面的产卵痕数量显著高于阳面,是阳面的7倍;柑橘大实蝇对柑橘果实所处的空间位置没有明显偏好。 |

| Abstract: | The Chinese citrus fruit fly Bactrocera (Tetradacus) minax (Enderlein) is one of the most harmful pests for fruit crops. Few studies have been conducted to determine the ovipositing behavior of this species, and little is known about the movement rhythms of the adults after their emergence. In this study,the movement rhythms of B.minax adults was revealed after their emergence and the oviposition preference of females was observed through field investigations. The results indicated that the majority of B.minax adults flied around the junction zone of mixed woods and orchard in the period of over twenty days after the emergence. And it reached a peak on June 11th, we trapped (24.0±5.6) insects per pot in a 5 m zone of mixed woods in the peak period,while the date was (74.7±21.9) insects per pot in the 5 m zone of orchard, which was significantly higher than that in other trapping zones. In the peak period of emergence, more than sixty percent of the adult B.minax flied around the junction zone. After the emergence peak,the distribution of B.minax in orchard tended to be uniform. Except that no B.minax adults was trapped in the sampling zone designated as 100 m zone in mixed woods, the trapped numbers of B.minax in other sampling zones showed no significant difference. Additionally,the greatest number of oviposition marks of B.minax were found to be in the middle of an orange, which were significantly more than those in two other parts such as the stem end and the fruit navel. Furthermore, the number of oviposition marks in the dark side of orange was seven times higher than those in the sunny side. It suggested that B.minax females preferred to oviposit in the fruit night side. However,B.minax females showed no preferences to the oranges from different locations. |
