无刺蜂是蜜蜂总科蜜蜂亚科麦蜂族 (Meliponini)昆虫 ,是热带地区多种经济作物的重要传粉蜂。广泛分布于世界各热带地区 ,如南美洲、非洲及东南亚各国 ,我国的海南及云南西双版纳等地均有分布 ,并有人工饲养。由于无刺蜂没有功能刺 ,因而更适合在大棚中授粉。 1 992年 ,日本学者Maeta用一种无刺蜂 (Nannotrig onatestaceicornis)在温室中进行了草莓授粉试验 ,取得了成功。哥斯达黎加学者E .J .Slaa于 1 996年 4月在大棚中对两种无刺蜂和有刺蜂 (西方蜜蜂 )对薄荷科一种装饰用植物 (Salviafarinacea)的授粉效果进行了比较试验。试验在 4个… 相似文献

温室内果菜类蔬菜缺乏昆虫授粉，产量低。笔者曾多次利用蜜蜂为温室内单性能结实的黄瓜“长春蜜刺”品种，荷兰引种的西红柿品种以及苦瓜、冬瓜和辣椒授粉，试验结果表明其坐果率、产量和质量比无蜂对照区都有明显提高。温室内西红柿利用蜜蜂授粉可代替２．４—Ｄ生长素的效果 相似文献

随着我国农业现代化水平的不断提高,设施农业的逐渐普及,通过授粉以提高农作物的产量和品质已成为一个重要的研究方向。蜜蜂和熊蜂都是理想的授粉昆虫,但熊蜂比蜜蜂更适合为大棚温室蔬果授粉。目前,国外已广泛通过人工繁育熊蜂为设施农作物传粉,并且获得了很好的经济效益和生态效益。熊蜂以其独特形态特征和生物学特性成为温室作物的理想授粉昆虫,利用熊蜂为设施农作物授粉,不但可以提高产量,改善果实品质,减少畸形果率,还可以有效避免激素授粉产生的污染,极大提高了经济效益。本文就是从熊蜂的生物学特性、国内外的研究进展、熊蜂授粉的优越性以及授粉效果等方面进行综述,为我国设施作物熊蜂授粉应用及推广奠定基础。 相似文献

Lizards have been reported as important pollinators on several oceanic islands. Here we evaluate the potential role of Galápagos lava lizards (Microlophus spp.) as pollinators across their radiation. Over 3 years, we sampled pollen transport by 9 lava lizard species on the 10 islands where they are present, including 7 single‐island endemics. Overall, only 25 of 296 individuals sampled (8.4%) transported pollen of 10 plant species, the most common being Prosopis juliflora, Exodeconus miersii, Sesuvium sp. and Cordia leucophlyctis. At least 8 of these plant species were native, and none were confirmed as introduced to the archipelago. Despite the low overall proportion of individuals carrying pollen, this was observed in 7 of the nine lizard species, and on 8 of the ten main islands (Española, Fernandina, Floreana, Isabela, Marchena, Pinta, Santa Cruz and Santiago), suggesting that this is a widespread interaction. The results reported here support the potential role of lava lizards as pollinators across their radiation, although they may represent a relatively modest contribution when compared with birds and insects. However, we cannot discard that lizards may be ecologically significant for particular plant species and ecosystems given the specific climatic condition and functional diversity of each island. 相似文献

紫花苜蓿(简称苜蓿)是我国和世界种植面积最大最重要的豆科牧草。由镰刀菌引起的根腐病(称为镰刀菌根腐病)是苜蓿生产上的主要限制因素之一,严重影响该牧草的产量和品质,导致草地衰败和利用年限缩短。镰刀菌作为一类重要的土传病原真菌,一直是苜蓿根腐病研究的热点。由于镰刀菌能在土壤中长期存活,且苜蓿为多年生牧草,导致苜蓿根腐病的防治尤为困难。从苜蓿镰刀菌根腐病的分布与危害、病原种类与生物学特性、侵染源及发病规律、镰刀菌对苜蓿的致病性及致病机理、苜蓿品种对镰刀菌的抗病性以及防治方法等方面阐述苜蓿镰刀菌根腐病的研究进展,并对今后的研究方向进行了展望,以期为苜蓿镰刀菌根腐病后续研究及其防治新方法的开发利用提供理论依据。 相似文献

Honeybees are the most critical pollinators providing key ecosystem services that underpin crop production and sustainable agriculture. Amidst a backdrop of rapid global change, this eusocial insect encounters a succession of stressors during nesting, foraging, and pollination. Ectoparasitic mites, together with vectored viruses, have been recognized as central biotic threats to honeybee health, while the spread of invasive giant hornets and small hive beetles also increasingly threatens colonies worldwide. Cocktails of agrochemicals, including acaricides used for mite treatment, and other pollutants of the environment have been widely documented to affect bee health in various ways. Additionally, expanding urbanization, climate change, and agricultural intensification often result in the destruction or fragmentation of flower-rich bee habitats. The anthropogenic pressures exerted by beekeeping management practices affect the natural selection and evolution of honeybees, and colony translocations facilitate alien species invasion and disease transmission. In this review, the multiple biotic and abiotic threats and their interactions that potentially undermine bee colony health are discussed, while taking into consideration the sensitivity, large foraging area, dense network among related nestmates, and social behaviors of honeybees. 相似文献
