大斑啄木鸟 Dendrocopos major(L.)是河西防护林重要蛀干害虫——十斑吉丁虫的优势天敌鸟类。本项试验在搞清该鸟生活习性的基础上进行了人工招引试验,取得了成功的经验,为今后在河西地区开展鸟类生态研究及利用展示了前景。 相似文献

近年来,我县由于栽植的多是杨树纯林,林木病虫害特别是蛀干害虫天牛局部区域发生较重。据调查,虫株率达50%。常造成2-3年生幼树被风折断。传统的防治方法对环境有污染,甚至人畜受到危害。利用啄木鸟防治就是采取生物的手段控制天牛种群数量。作者在人工招引啄木鸟防治天牛方面做了一些试验,于2005年2月1、2日在本县的刘集镇挂啄木鸟巢100个,并于2005年4月15、21、22日进行了调查,5月中旬对试验林分天牛的危害情况进行了调查。现将结果报告如下。 相似文献

The Great Spotted Woodpecker Dendrocopos major (L.), one of the natural predators of Anoplophora glabripennis (Motsch.) (Coleoptera: Cerambycidae), is resident to Wulate Qianqi County of the Inner Mongolia and widely found in shelter plantations. In August 2005 and 2006, 174 and 153 nest-cavities of Great Spotted Woodpeckers were found respectively in Wulate Qianqi County and 22 breeding nest-cavities were investigated in 2007. The results showed that mostly willow species were selected for nesting by the Great Spotted Woodpecker, but mature poplar trees also could be chosen. Nest cavities were often found with a protuberance above the cavity entrance or with a downward sloping gradient, or both. The selection of the height of the nest-cavity height was not significant. The vertical diameter of the nest-cavity entrance (VDE) and the horizontal diameter of the nest-cavity entrance (HDE) ranged from 5.0 to 5.8 cm. The results also indicated that the compass orientation of more than 60% of nest-cavities were towards the north, northeast and east. This study suggests a convergence of some nest-cavity characteristics of the Great Spotted Woodpecker in shelter plantations and will help us to make artificial nest for conserving the woodpecker and, as well, use the bird for controlling pests. 相似文献

指出了白腰鹊鸲是广泛分布于南亚和东南亚的雀形目鸣禽,其鸣声清脆悦耳,但目前中国还没有关于白腰鹊鸲的繁殖生态学研究。白腰鹊鸲繁殖期间是利用已有洞资源来筑巢的次级洞巢鸟,通过放置人工竹筒巢及繁殖期的观察,对白腰鹊鸲的巢址选择、窝卵数、卵情况、繁殖失败因素等进行了调查研究。结果表明:白腰鹊鸲的繁殖季为每年的3月下旬到7月下旬,繁殖高峰期为4~6月份;白腰鹊鸲窝卵数一般为4枚,单枚卵重3.18±0.27g;白腰鹊鸲一个完整的育雏周期为26±2 d,其中孵化周期为15±1 d,育雏周期为11±3 d。巢材的植物包括14科18属20种,主要营巢材料包括羽叶金合欢(Acacia pennata)、托叶黄檀(Dalbergia stipulacea)、铁刀木(Senna siamea)。巢址距道路最近距离为20.72±16.34 m,距离房屋最近距离为31.29±19.11 m,巢高为1.27±0.4 m。白腰鹊鸲巢失败的主要因素为巢被捕食。 相似文献

2011年3~5月使用直接观察法对微山湖新薛河湿地内的鸟类巢穴进行调查,共发现鸟类巢穴90个,其中喜鹊Pi-ca pica巢36个,池鹭Ardeola bacchus巢54个,其他鸟类的巢穴2个。对影响鸟类巢址选择的因素进行了分析,结果显示距水源的距离、营巢树高和营巢树是影响喜鹊巢址选择的主导因子,次要因子是巢距地面高度、距公路的距离和人为干扰状况,再次是巢分支数;距公路的距离、巢距地面的高度、营巢树胸径和营巢树高是影响池鹭巢址选择的主导因子,次要因子是距水源的距离、人为干扰状况和巢分支数。 相似文献

Predation hazard is one of the most important factors that affect foraging behavior. Light intensity is an indirect measure
of a predation hazard for nocturnal rodents. In 1988 and 1989, I conducted laboratory experiments to reveal the effects of
the predation hazard on foraging behavior of two species of field mice,Apodemus speciosus Temminck andA. argenteus Temminck (Rodentia: Muridae), which co-exist in many areas in Japan. I released a mouse into the experimental arena, where
I set one nest box and two food stations (one near and the other far from the nest box), and recorded the foraging behavior
for sixA. speciosus and sixA. argenteus mice. I planned to illuminate the experimental arena when the mouse left the nest box to mimic a predation hazard during
excursion. The light treatment decreased the time the mouse spend outside the nest box, the duration of an excursion, the
number of visits to the food station far from the nest box, and the number of peanuts handled at the food station far away.
Mice handled food more intensely at the food station near to the nest box and tended to carry more foods back to the nest
box and eat them there during the light treatment period than the control period. These behavioral changes, which seemed to
be adaptive to avoid the predation hazard in the field, were more apparent in smaller mice,A. argenteus, than larger mice,A. speciosus. 相似文献
