New Study Sheds Light on How CO2 Affects Bee Reproduction.
The team of researchers, led by an entomologist from Penn State’s College of Agricultural Sciences, set out to figure out how carbon dioxide appears to bypass diapause, a phase similar to hibernation in which bees sleep during the winter, to trigger the reproductive process in bumblebee queens.
Carbon dioxide, the researchers discovered, first caused a change in metabolism, which then caused secondary effects on reproduction.
The findings, published recently in Insect Biochemistry and Molecular Biology, contradicted previous hypotheses.
“Previously, it was thought that CO2 directly affected reproduction, but this study provides some of the first evidence that this is unlikely,” Etya Amsalem, associate professor of entomology, said.
“We discovered that CO2 alters how macronutrients are stored and redistributed in the body.
The fact that the reproductive process is initiated is simply a byproduct of these processes.”

Addition to inducing a calming effect Carbon dioxide can also cause a variety Of other physiological responses while Bumblebee Queens typically enter Diapause during the winter months before Beginning a new colony in the spring bee Farmers and researchers may use carbon Dioxide to trigger the Queen's Reproductive process earlier than Naturally occurring amsulum stated that She and the other researchers wanted to Conduct the study for various reasons First because carbon dioxide is so Widely used she believes it is critical To understand its mode of action in Insects particularly bumblebees where Commercial Apiaries use it to produce Colonies for year-round pollination the Second goal was to understand better how Using CO2 could influence research Results we know the carbon dioxide has a Variety of effects including behavioral Effects insulin explained so if you're Studying the effects of a specific Manipulation on B Behavior well also Using CO2 as an aesthetic are you Studying the effect of the manipulation Or the effect of the CO2 the researchers Connected two phases of experiments a City the researchers first wanted there To understand carbon dioxide Physiological effects on bumblebee Queens the researchers suffered at the Base into two groups those that were not
Treated and those that were the bees Were then examined three times Immediately after the treatment three Days later and 10 days later the Researchers examine the ovaries and Measured macronutrient concentrations in Several tissues at each time point which Provided information about changes in Metabolic function over time the CO2 Treated Queens had higher levels of Ovarian at the ocean pencils where Treated Queens also had a shift in Macronutrient allegation with fewer Lipids in the fat body and more like it In a stored form of glucose and protein And ovaries the researchers determine How carbon dioxide affected metabolism And reproduction with this Foundation What was they use carbon dioxide to Treat two more groups of Queens one of Their ovaries removed in another with a Juvenile hormone antagonist according to Researchers this antagonist reduces the Levels of juvenile hormone and Bumblebees which regulates reproduction And accelerates metabolism the Scion is Suspected that this hormone is important And how carbon dioxide affects the Facility of insects this time they Discovered that bees were their ovaries Removed experience a similar change in Macronutrients of bees in a control Group within that ovaries the Researchers concluded a carbon dioxide
Effects metabolism first because bees Without reproductive organs experience The same effect furthermore be treated With the juvenile hormone inhibitor did Not exhibit these metabolic effects Confirming the role of this hormone in Mediating the effects of carbon dioxide Aborting the researchers according to Amsolum the findings are critical for Understanding how carbon dioxide affects Bumblebees and all insects as scientists We're trying to find an effect they all Have in common so we can find the Precise process or mechanism that is Creating these effects she explained for Example it promotes bee reproduction but May inhibit reproduction and other Insects it has an inconsistent effect on Reproduction however we believe it is Consistent in how it affects metabolism Foreign [Music]
