Why don't bees pollinate tomato plants?
They don't have that behavior, and there's no reason for them to visit the flowers because the pollen is enclosed inside the anthers, unavailable for collection, and there is no nectar reward. Native bees like bumblebees (Bombus spp.) and mud bees (Anthophora urbana) buzz-pollinate tomato flowers.

Although bumble bees are native, they like non-native and native plants. Large groupings of diverse blooming plants provide consistent bumble bee food throughout their season.
Do bees need to pollinate tomato plants?
There is no need to encourage bees into the greenhouse to pollinate tomatoes. According to Prof Dave Goulson in 'Bumblebee Behaviour And Ecology', tomatoes are self-fertile, and capable of self pollination, but insect visits are needed to move pollen from the anthers to the stigma of the flower.
Do bees eat tomatoes?
Nothing epitomizes summer as eating a warm, vine-ripened tomato right after picking it late in the afternoon. Tomato flowers do depend upon pollination to develop into fruits, but because of its structure, honey bees are unable to access the pollen.

Why have the bees disappeared from my garden?
Plants and shrubs vary in the amount of nectar and pollen they offer as they grow. Quite simply, the bees may no longer be attracted to – e.g. my manuka shrub, despite being all over it previously, because it is no longer producing so much nectar. So they forage elsewhere, and leave and leftover for the hoverflies.

Where do yellow tomato flowers come from?
Yellow tomato flowers hang down from the stem of the plant. The petals extend backward from the central reproductive structure, which consists of a cone made from five fused-together stamens that produce pollen from their anthers. The pollen comes out from pores at the tips of the anthers when the flower vibrates.
How do bees land on a flower?
Bumblebees and mud bees land on the bottom of the downward-pointing flower, grasping the anther cone with their legs. The pointed end of the cone rests against the underside of their abdomen. They then vibrate their wing muscles, and you can hear an audible buzz when they do this. This shakes the pollen down the anther tube, releasing it to land on the flower's own stigma and the bee. If it is a short-styled flower, it becomes self-pollinated. If it is a long-styled flower, the stigma presses against the bee's body and can be cross-pollinated with pollen on the bee's body from other plants.
What do bumblebees do?
Some species have a red color on their abdomens. The queen bumblebee overwinters in a protected area and finds a nesting site in spring, usually an old mouse nest or a burrow, and begins the nest herself. Once she has worker bees, she stays home and lays eggs. The nest increases in size and toward summer's end, new queen bees and male bees emerge and mate. The inseminated queen then overwinters to repeat the cycle. Bumblebee colonies, usually containing the impatient bumblebee (Bombus impatiens), are often used to pollinate greenhouse tomatoes, with one hive able to work about half an acre of tomatoes. Workers are sometimes paid to use electric toothbrushes to pollinate flowers.
How do mud bees make their nests?
The female bee constructs cells at the ends of branching burrows. She puts pollen and nectar in each cell, lays an egg on the food and closes the cell, with the bee larva receiving no other maternal care. In favorable locations, hundreds of females make aggregate nests. Mud bees have a higher-pitched vibrating buzz than bumblebees. They are faster fliers than bumblebees or honeybees, and it's often hard to get a good look at them.
What is the buzz pollination of flowers?
The flower is built for a particular kind of bee pollination called buzz pollination, or sonication, where a strong-winged bee lands on the flower and vibrates its wings to dislodge the pollen from the anthers. Most modern cultivars grown outdoors also get pollinated by the wind shaking the plant to free the pollen.
Where do mud bees land?
Bumblebees and mud bees land on the bottom of the downward-pointing flower, grasping the anther cone with their legs. The pointed end of the cone rests against the underside of their abdomen. They then vibrate their wing muscles, and you can hear an audible buzz when they do this.

Corn is a very low-value pollen ( though the be es don't really know that ); they usually hit it only during a real dearth. Wind-pollinated plants in general, with their tiny pollen grains, are emergency rations only.
What kind of bee pollinates tomatoes?
When it comes to pollinating tomato plants, one kind of bee stands out from all the rest. The native bumble bee pollinates tomatoes with such efficiency that greenhouse tomato growers put that bee to work on their crops. Tomato farmers whose plants receive regular visits from bumble bees may have 50 percent of their tomatoes grow twice as large as normal, according to a University of California website article. Bumble bees pollinate tomatoes by vibrating their bodies in a way that causes all the pollen to flow. This "buzz pollination" is done by only certain kinds of bees.
How to keep bumble bees healthy?
They even pollinate during light rain. Keep bumble bees healthy by avoiding the use of pesticides whenever possible. If pesticides must be used, restrict their applications to times such as sundown, when bumble bees are inactive. Try to keep all pesticides away from blossoms, and be aware of all kinds of pollinators that may be active at the time use use pesticides. Bumble bees can be attracted by a water source and a muddy puddle in a shallow dish or soil. Keep such a water sources full and pesticide-free.

Do wasps collect pollen?
Wasps do not collect pollen, but do visit blooms to feed. Unlike honey bees, wasps don’t have body hair or pollen baskets to trap pollen. Bees use both of these to transport pollen from plant to plant, and in the process, pollinate plants. (See: 5 Amazing Facts About Honey Bees)

How did honey bees affect the ecosystem?
Bringing in honey bees reduced the connectedness of the plant-pollinator networks. Nestedness and modularity, two indicators of ecosystem resilience, also declined. While some plant species enjoyed higher fruit set, fruits sampled nearest the apiaries contained only aborted seeds. “The impact of the beehives is so dramatic,” says Valido, “You can detect disruption between plants and pollinators just the day after beehive installation.”
What is the role of honey bees in the ecosystem?
Honey bees are extreme generalist foragers and monopolize floral resources, thus leading to exploitative competition—that is, where one species uses up a resource, not leaving enough to go around. But determining honey bees' influence on natural ecosystems requires empirical testing.
Why are honey bees important?
To many people, honey bees symbolize prosperity, sustainability and environmentalism. But as a honey bee researcher, I have to tell you that only the first item on that list is defensible. Although they are important for agriculture, honey bees also destabilize natural ecosystems by competing with native bees—some of which are species at risk.
What did Colla and her colleagues find about pollinators?

What are some invasive plants?
Many of those weedy species are also invasive, including Scotch broom, dandelions, Himalayan blackberry and Japanese knotweed, among others. And beekeepers secretly love invasive plants.

Do honey bees benefit native bees?
And while honey bee–centric businesses often support initiatives that benefit native bees, such as developing bee-friendly habitat, the financial contributions pale in comparison to what could be achieved if funds were applied to these initiatives directly. “Beekeeping companies and various non-science-based initiatives have financially benefitted from the decline of native pollinators,” Colla explains. “These resources thus were not allocated to the actual issue people are concerned about.”
Did the colonies produce honey?
And the colonies did not produce a crop of honey. Colony densities in some locations have become too high, facilitating the spread of disease and exacerbating problems with poor nutrition. If it was this hard to keep my honey bees healthy, I’m not sure I can bear to think about the wild bees.
