柑橘大实蝇Bactrocera minax(Enderlein)是主要分布于我国的柑橘类重要害虫,本文通过对在室外养虫笼、室外无橘树网室和有橘树网室中初羽化柑橘大实蝇成虫的起飞活动日节律和降落位置观察试验研究,为应用谐波雷达技术跟踪该成虫运动行为试验提供合适释放时间点和选择跟踪的方位。本研究结果表明,初羽化的柑橘大实蝇雌雄成虫起飞活动高峰上午在9∶00-10∶00,下午在16∶00-17∶00时。在室外养虫笼、室外无橘树网室和有橘树网室中,初羽化成虫降落的在东南、东北、西南、西北4个方位网上和在东、西2个方位网上的数量均没有偏向性。在空间相对较小的室外养虫笼中,初羽化成虫喜欢向上飞行停留在上部网上,而在空间相对较大的室外无橘树网室和有橘树网室中,大多数时间段,初羽化成虫没有这种明显偏向性。在有橘树网室中,初羽化成虫降落在橘树上的东南、东北、西南、西北4个方位面上成虫数量均没有明显偏向性,但85.5%成虫喜欢停留在橘树上部位置;有52.2%成虫喜欢停留在橘树上。结果还表明,在室外养虫笼中,太阳光照射强度与初羽化成虫起飞频率之间直线线性相关性不明显。在有橘树网室中,太阳光照射强度与初羽化成虫起飞虫数之间存在明显直线线性相关性,而在室外养虫笼和无橘树网室中,它们之间的这种相关性不明显。这可能与成虫在橘树上避光行为有关。
Bactrocera minax (Enderlein) is the most important citrus pest mainly distributed in China. In this paper, the citrus fruit fly adults are newly emerged in outdoor rearing cages, Takeoff Day rhythm and landing observation observation test study for the application of harmonic radar technology to track the adult kinematic behavior test to provide a suitable release time point and select the tracking position. The results of this study showed that the male-male adults of the newly emerged Citrus Dicata fly peaked at 9:00 to 10:00 am in the morning and from 16:00 to 17:00 in the afternoon. In outdoor rearing cages, outdoor orange treetops and orange treetops, the number of newly emerged adult worms landed in the four southeastern, northeast, southwest and northwest orientations online and in the east and west two directions online Bias. In the relatively small outdoor rearing cages, the first feathered adults prefer to fly upward in the upper part of the net, whereas in the relatively large outdoor orange-treetops and orange groves, most of the time, Eclosion adults do not have this obvious bias. There are orange trees in the network room, landing in the number of early adult emergence southeast, northeast, southwest, northwest azimuth plane four adult orange trees were no obvious bias, but 85.5% of adults prefer to stay in the orange tree position; there 52.2% of adults prefer to stay on orange trees. The results also showed that there was no linear linear correlation between sunlight intensity and take-off frequency of newly emerged adult worms in outdoor rearing cages. There was a significant linear linear correlation between the intensity of sunlight exposure and the number of first-fecundity adult worms in an orange house, while in the outdoor rearing cages and orange-free tree nests, the correlation between them Not obvious. This may be related to adults in orange trees on the dark behavior.
