Several factors make corn syrup good for bees, from p-coumaric acid, a plant-derived compound that revs up the bee’s defense system. High-fructose corn syrup, on the other hand, lacks p-coumaric acid. Beekeepers, who were using mite-killing chemicals in hives in the 1970s, have recently returned to this natural remedy.

Is corn syrup good for bees

High fructose corn syrup

The answer is no, unless you like the taste of high fructose corn syrup. HFCS contains up to 77% fructose, which is sweeter than glucose or sucrose, but lower in calories. Corn syrup is used to sweeten baked goods and maintain freshness. HFCS helps prevent crystallization of certain products. Honey that is high in fructose is slow to crystallize, while honey that is high in glucose crystallizes quickly. In addition to HFCS, you can also get granulated sugar, which contains a 50/50 mix of fructose and glucose. These two sugars are found naturally in many plants and their nectar.

While HFCS is generally safe for bees, it is not recommended for use in commercial operations. The chemical properties of HFCS (especially the low pH level) can lead to toxins, including hydroxymethylfurfural. HMF causes dark coloring in honey and is toxic to honey bees. That’s why HFCS for commercial bee operations should be stored in a temperature-controlled facility. Beekeepers should also avoid mixing it with old syrup or water.

Commercial bees are often fed high-fructose corn syrup instead of honey. This practice began in the 1970s, when scientific studies indicated it was safe for bees. Ultimately, the disappearance of bees in hives may be caused by high-fructose corn syrup. However, the good news is that high-fructose corn syrup is not toxic to bees and can help reduce exposure to pesticides.


Some beekeepers may have concerns about HFCS, or high fructose corn syrup. This sweetener contains a higher percentage of fructose than glucose. Even though it’s fine in highly purified form, HFCS can be converted to hydroxymethylfurfural, which is toxic to bees. At temperatures below 120F, HFCS becomes a caramel color, or yellow with a brown tint.

While HFCS is generally considered safe for use in honey bee feed, the chemical properties of fructose and low pH may compromise bee health. HFCS is thought to promote the formation of hydroxymethylfurfural, a bee toxin. Bees’ immune systems may have been compromised by exposure to HFCS, but HFCS doesn’t contain enough sugar to be toxic to be harmful.

To test whether HFCS is bad for bees, scientists fed 10 nucs of five-frame colonies with sucrose and high-fructose corn syrup. The sucrose-fed colonies produced significantly more wax than HFCS-fed colonies. Moreover, sucrose-fed colonies produced more honeycomb, with an average mass of 8.27 kg. Despite the potential negative effects of HFCS on bee health, it’s worth considering for beekeepers.

However, there are other problems with HFCS. Some researchers believe that HFCS may be responsible for the disappearance of bee colonies in the United States. This disease affects about one-third of the bee population. However, the causes are still not understood. Honey bees produce wax and pollen, which give them a chemical to break down pesticides. A recent study at the University of Illinois suggests that HFCS may be bad for bees.

Cane sugar syrup

In warmer weather, bees do not mind eating brown sugar solids. This is because they can store it for later use, and they can also eat it during periods of limited cleansing flight. However, feeding them sugars other than plain granulated white sugar is not recommended. Honey is plant-based, but it is not necessarily sweet. Sugars derived from other sources can cause nosema or bee sickness.

Bees prefer the liquid form of sugar water instead of solid granules. They prefer this because it closely resembles plant nectar. This is why most beekeepers feed their colonies with a liquid feeding supplement. This also prevents mold from growing in the hives. A few tips will help you prepare sugar water for your bees and feed them with it. These tips can help you increase the chances of successful honey production.

The main difference between pure sugar and cane sugar is the source of sugar. Bees ingest sugars from both plants. But cane sugar is better for bees because it contains more nutrients. If you have a bee-friendly diet, you can feed your honeybees with cane sugar syrup. This type of syrup also contains more than 80% sucrose, which is higher than sugar in honey.

Off-spec HFCS

High Fructose Corn Syrup is commonly fed to bees in the US and eastern Canada, but is it good for bees? In many areas, the answer is no, as HFCS is not as beneficial to bees as sucrose. In fact, some studies suggest that off-spec HFCS can be harmful to bees. Its hydroxymethylfurfural content is dangerous to bees, causing damage to the digestive tract and possibly killing the entire hive. However, many beekeepers report mixed results with HFCS and honey.

While the vast majority of HFCS is manufactured via enzymes, some is produced by acid hydrolysis. This acid hydrolysis method has proven harmful to bees, and in Canada, off-spec syrup is now banned. Research by Dr. Rob Currie shows that off-spec HFCS may be harmful to bees, though he hasn’t pinpointed why. Beekeepers should keep an eye out for two signs of off-spec syrup. First, if the syrup has a low pH and is colored, then the syrup may be off-spec.

Some researchers claim that off-spec HFCS is beneficial for bees. HFCS is not a good choice for wintering because it contains hydroxymethylfurfuraldehyde, a chemical that is toxic to honeybees. However, there are several studies to back up the benefits of HFCS for bees. Some studies even suggest that HFCS may play a role in the recent outbreak of Colony Collapse Disorder, which has destroyed more than one-third of the American honeybee population.

Effects of diet treatment

The authors analyzed gene expression in honey bees fed HFCS or sucrose and compared them to those fed a diet of sucrose. They found that the two groups of bees had remarkably different transcriptomic profiles. Additionally, the diets elicited distinct differences in gene expression among different age groups and viral loads. However, the effects of sucrose and HFCS on gene expression were modest.

The authors manipulated the diet of honey bees by providing them with homemade syrups. These syrups contained a mixture of 50 percent sucrose and 50 percent high fructose corn syrup. After observing the bees daily, the samples were flash frozen and stored at -80 degC. Among the effects observed, the highest levels of apoptosis were observed in the surviving honey bees.

The researchers used the same protocol as in previous experiments, feeding newly emerged bees three different types of syrups. One group received a 2:1 solution of sucrose with lemon, a mixture of lemon juice, and another group received L+25 degC with HCl. The last group received the same solution, but the acidity levels were different. Honey bees were highly sensitive to these sugar syrups, and this made the experiment difficult.

High-fructose corn syrup (HFCS) is an ideal alternative for sucrose. The same amount of HFCS is equivalent to honey, which is an ideal food source for colonies. It is also more cost-effective than sucrose and less labor-intensive to administer. Honey bee colonies in temperate climates consume 20-25 kilograms of syrup between November and April. HFCS has similar fructose-to-glucose ratio to honey. The fructose content of HFCS is similar to that of honey, and it is considered to be as sweetener than sucrose.

Effects of off-spec HFCS on bee populations

Several studies suggest that HMF may be contributing to the decline in honeybee populations, a condition known as colony collapse disorder. A 1966 study, led by Bailey, supported claims that HMF can cause dysentery-like symptoms and gut ulcerations in bees. Beekeepers give HFCS to their colonies to promote brood rearing and increase production of honey. HFCS would not be harmful to bees if it were properly stored and not used as a food additive.

Beekeepers often compare the effects of HFCS and cane sugar syrup on bee colonies. In one study, sucrose syrup was found to yield higher wax production, while high-fructose corn syrup led to less honeycomb formation. This study found that sucrose syrup resulted in a mean mass of 8.27 kg for colonies. The results of this study are encouraging, but more research is needed to determine whether or not HFCS is harmful to bee populations.

Off-spec HFCS is not a good alternative to sucrose, but many beekeepers are switching to it. HFCS is easier to handle than sucrose and is cheaper. Beekeepers also like HFCS because it is cheaper than sucrose and comes in liquid form. Honey produced from HFCS often contains hydroxymethylfurfural, which can harm bees’ digestive systems and even kill a hive.
