| 本文利用引诱剂诱捕器，对香蕉假茎象甲Odoiporus longicollis (Oliver)成虫在蕉园中的活动高度、活动方向和活动节律进行研究，旨在明确该虫的田间活动规律，为其防控技术的研究与应用提供科学依据。结果表明，诱捕器的挂置高度对香蕉假茎象甲成虫的诱捕效果有一定影响，距地面160 cm的诱捕器所诱捕的成虫数量最大，而该高度是香蕉叶鞘及叶柄所处位置，说明成虫多在此处活动。而诱捕器的挂置方位对诱捕效果影响不大，挂设在东南西北四个方位的诱捕器的诱虫量差异不显著，说明香蕉假茎象甲成虫在蕉园活动时，对方向没有明显偏好。此外，在活动节律上，香蕉假茎象甲成虫多在傍晚至凌晨时分活动，16:00至翌日4:00的雌、雄虫诱虫量分别占全天雌、雄虫诱虫量的92%和96%。 |
| 英文摘要: |
| Adult activity of Odoiporus longicollis (Oliver)was determined to provide scientific basis for conducting research and application of its control measures For this, the flight height, flight direction and circadian rhythms of O longicollis adult was studied by using attractant and trapping method The results showed that the hanging height of traps had some influence on the trapping of O longicollis The number of insects trapped in the height of 160 cm traps were maximum This height was the location of the banana sheath and petioles, which illustrated O longicollis adults was mainly active here The hanging orientation of traps had little effect on the trapping effect of O longicollis and there was no significant difference in the numbers of adult trapping on east, west, south and north, which illustrated that O longicollis adults had not clear preference for the direction when flying in the banana field On circadian rhythms, O longicollis adults were observed mainly active from evening (16:00 pm)to early morning (4:00 am)where the number of trapped male (92%)and female (96%)insects accounted separately during the whole day |
