If the number of bees continues to decline, plant population and diversity will be affected and the threat will extend up the food chain to birds and mammals, as well as to humans who rely on the fruits and berries of insect-pollinated
plants for 40 per cent of all food and beverages we consume.
Dr Richard Comont atThe Bumble Bee Conversationhas said: "Without any bees at all the main thing that would suffer is the recruitment rate of insect-pollinated
plants (ie the number of new plants of each species that started growing each year).
Tomatoes, on the other hand, are insect-pollinated
, so the cultivars need to be kept separate from each other.
Go for insect-pollinated
plants, whose flowers enclose the pollen, so insects have to climb inside - foxgloves, honeysuckle, penstemon and snapdragon.
Most of our fruit crops are insect-pollinated
, as are the vast majority of our wild plants
Flowers are insect-pollinated
(they are brightly coloured to attract bees) and so don't cause hay fever unless you have a lot of contact with them; for example, if you're a florist.

We often don't need to be quite as careful with our smaller plants, the annuals and perennials, and actually it is beneficial on several levels to use many that are strictly insect-pollinated
. It is good for our immune systems to be exposed to some pollen; this makes our bodies stronger.
The pollen grains of insect-pollinated
crops are sticky for easy transport, and many plants advertise for pollinator services with colorful flowers--visual billboards promising a sweet drink of nectar, some nutritious pollen and occasionally a safe place to sleep.
Approximately one third of the total human diet is derived directly or indirectly from insect-pollinated
Plantains exhibit the transition from the insect-pollinated
to wind-pollinated flowers (Preston et al., 2011) and unusually fast evolution (Ronsted et al., 2002; Cho et al., 2004): for 5.5 million years, this group produce hundreds of species and colonized of all continents including Antarctic.
