Why Are Bees Important for Agriculture and Farming

Bees pollinate at least 87 major food crops grown across 200 countries, and in the United States alone, honeybee pollination accounts for $15 billion worth of agricultural production each year. Without bees, many of the fruits, nuts, and vegetables that fill grocery stores would either disappear entirely or become far more expensive. Their role goes well beyond simply helping plants reproduce: bees directly influence the size, shape, nutritional content, and shelf life of the food we eat.

Which Crops Depend on Bees

Honeybees pollinate more than 130 types of fruits, nuts, and vegetables in the U.S. Globally, crops like cocoa, kiwi, passion fruit, watermelon, almonds, coffee, and soybeans all rely heavily on bee pollination. Some of these crops, particularly almonds, would produce almost nothing without bees visiting their flowers to move pollen between blossoms.

Cash crops illustrate the scale of this dependency. In just one Brazilian state (Pará), the pollination service value of four crop groups totaled nearly $950 million: açaí palm alone accounted for $635 million, cocoa for $187 million, soybeans for $98 million, and watermelon for $26 million. Across the 36 crops grown in that region, 55% depend on animal pollinators, the vast majority of which are bees. These numbers repeat in agricultural regions worldwide.

How Pollination Improves Crop Quality

Bees don’t just determine whether a crop produces fruit. They determine how good that fruit is. When bees thoroughly pollinate a strawberry flower, the resulting berry is heavier, more symmetrical, redder, and firmer than one that received poor pollination. That firmness is commercially significant because it extends shelf life, reducing fruit loss by at least 11%. Poorly pollinated strawberries tend to be misshapen, lighter in color, and softer, making them more vulnerable to fungal infections and less likely to meet commercial grading standards.

These quality improvements happen because pollen triggers the production of hormonal growth regulators inside the developing fruit. The more completely a flower is pollinated, the more evenly the fruit develops. This mechanism isn’t unique to strawberries. It applies across many pollination-dependent crops, influencing everything from apple symmetry to blueberry size.

Bees and Global Nutrition

The connection between bees and human nutrition runs deeper than most people realize. Many of the most pollinator-dependent crops are also among the richest in essential vitamins and minerals. In parts of Southeast Asia, as much as 50% of plant-derived vitamin A production depends on pollination. Iron and folate have lower but still meaningful dependencies, reaching 12 to 15% in parts of China, Africa, Mexico, and Brazil.

This overlap between pollinator dependence and nutrition creates a vulnerability. Regions where vitamin A production relies most heavily on pollination are nearly three times more likely to have vitamin A deficiency in the population. Iron deficiency anemia in pregnant women is more than three times higher in areas where at least 15% of plant-derived iron depends on pollinators. If bee populations decline in these regions, the nutritional consequences could be severe for communities already at risk of malnutrition.

Wild Bees vs. Managed Honeybees

Most people picture honeybees when they think about agricultural pollination, but wild bees, particularly bumblebees, are often more efficient pollinators on a per-visit basis. In direct comparisons, bumblebees deposited roughly 2.5 times more pollen grains per flower visit than honeybees (about 77 grains versus 30). They also removed significantly more pollen per visit and visited flowers more frequently, while spending less time on each flower, roughly 8 seconds compared to 19 seconds for honeybees.

Studies on tomatoes and blueberries confirm this pattern: bumblebees transfer more pollen and increase fruit set more effectively than honeybees. This doesn’t make honeybees unimportant. Managed honeybee colonies can be transported to fields in huge numbers during bloom periods, which is why crops like almonds rely on them so heavily. But it does mean that wild bee diversity is a critical piece of agricultural pollination, not a backup system. Farms benefit most when both managed and wild bee populations are healthy.

Colony Losses Are at Record Highs

The most recent national beekeeping survey found that 55.6% of managed honeybee colonies in the U.S. were lost between April 2024 and April 2025. That is the highest loss rate since the annual survey began in 2010. State-level losses ranged from 34.3% to 90.5%, a wider and more severe range than any previous year.

Winter losses were especially elevated at 40.2%, exceeding all historical averages and surpassing the previous record of 37.7%. Beekeepers can replace lost colonies by splitting surviving hives or purchasing new packages of bees, which is why total colony numbers haven’t collapsed despite these loss rates. But the cost and effort of constant replacement is unsustainable, and it doesn’t address the underlying pressures: pesticide exposure, habitat loss, parasites, and disease.

Farming Practices That Help Bees

The way a farm manages pests has a direct, measurable impact on bee health. Fields using integrated pest management, which reduces reliance on chemical pesticides and uses targeted alternatives, showed dramatically better outcomes for pollinators compared to conventionally managed fields. Managed bees placed near these fields had higher growth and lower mortality. Wild pollinator abundance increased by 147%, and species richness jumped by 128%.

One reason for the improvement: lower concentrations of neonicotinoids (a class of insecticides particularly harmful to bees) in hive material near integrated pest management fields. Notably, these pollinator gains showed up within a single growing season, unlike strategies such as planting wildflower strips, which can take several years to generate measurable effects. Even so, non-crop flowers like agricultural weeds serve as important food sources for pollinators. In pesticide-heavy landscapes, those weeds can also become a secondary route of insecticide exposure, which means reducing chemical use across the farm matters more than creating isolated patches of habitat.

For farmers, the takeaway is practical: pollinator-friendly pest management doesn’t just protect bees. It attracts a wider community of wild pollinators to the farm, which can improve pollination coverage and, ultimately, crop yields and quality.
