CHE SIGNIFICA NECTARY IN INGLESE
Nettare
Il nettare è un liquido ricco di zucchero prodotto da piante nelle ghiandole chiamate nettari, sia all'interno dei fiori con cui attira animali impollinanti, che da nettariferi extraflorali, che forniscono una fonte nutritiva agli mutualisti animali, che a sua volta garantiscono protezione antiherbivora. Impollinatori comuni che consumano nettare includono api, farfalle e falene, colibrì e pipistrelli. Il nettare svolge un ruolo importante nell'economia foraggiante e nell'evoluzione globale delle specie che mangiano il nettare; Per esempio, il nettare e le sue proprietà sono responsabili dell'evoluzione differenziale dell'ape africana, A. m. Scutellata e la miele araba occidentale. Il nettare è un elemento ecologicamente importante, la fonte di zucchero per il miele. È utile anche per l'agricoltura e l'orticoltura perché le fasi adulte di alcuni insetti predatori, come quasi tutte le vespe solitarie, si nutrono di nettare. A loro volta queste vespe cercano insetti di polvere agricola come cibo per i loro giovani. Per esempio, le vespe a filo di vita sono note per la caccia di bruchi che sono distruttivi alle colture. La secrezione del nettare aumenta mentre il fiore viene visitato dagli impollinatori.
