科普專欄–薯不揀單 - 三十秒科學–又食又拎的採花賊

不少花朵均依靠著各昆蟲的前來，使花粉黏貼在牠們的身體，從而往外繁殖。453Please respect copyright.ＰＥＮＡＮＡbWDBd8HaOQ

吸引昆蟲前來的技倆可謂千變萬化，囑目的顏色視覺效果、散發香氣或荷爾蒙吸引昆蟲，以及佈下蜜汁等等。453Please respect copyright.ＰＥＮＡＮＡVh52GL0AmV

這次將提及的技倆，就是花朵提供可讓昆蟲吃下肚的粉末。453Please respect copyright.ＰＥＮＡＮＡU3u6C547II

(圖2)這是中國本土蘭花的其中一品種，名為寬口杓蘭 (Cypripedium wardii)。453Please respect copyright.ＰＥＮＡＮＡdmJKhY1BvO
它既不會發出香氣，亦不會排出蜜汁給予蔡SIR，但它依舊有不少採花賊前來拜訪。453Please respect copyright.ＰＥＮＡＮＡeiIvQQFMIe

採花賊名單包括休班蜜蜂、食蚜蠅，甚至連蜘蛛也有份參與，究竟它有甚麼魅力呢?453Please respect copyright.ＰＥＮＡＮＡTVoaNaj3uH

難道牠能幫忙按摩，又或者能釋除昆蟲的腰痛?453Please respect copyright.ＰＥＮＡＮＡpG7UjpPLV3

(圖3)經科學家發現，原來這種蘭花(黑色箭嘴所指位置)佈滿類近粉末的物質，脂肪含量極高，而碳水化合物及蛋白質含量則非常之低。453Please respect copyright.ＰＥＮＡＮＡeXxY0RzWmQ

這些脂肪粉末且能在各採花昆蟲中的腸道中可找得到，證實牠們確實會吃掉這些粉末。453Please respect copyright.ＰＥＮＡＮＡpP3iBWi4OB
而當以人為的方式抹去這些粉末的話，某部份的昆蟲亦沒有到訪該蘭花，可見脂肪粉末確是吸引昆蟲前來幫忙散播花粉的一大誘因。453Please respect copyright.ＰＥＮＡＮＡIZW8WGZFHp
