Kansas State 1xbet online casino

MANHATTAN -- Kansas State University entomologists have helped identify a neuropeptide named 1xbet online casino that regulates the sexual activity and reproductive ability of insects.

The team is the first to observe and name the neuropeptide, which is composed of short chains of amino acids in the brain of 1xbet online casino and arthropods. The finding may open new possibilities for environmentally friendly pest management, said Yoonseong Park, professor of entomology at Kansas State 1xbet online casino .

Park and colleagues recently published their findings in the study, "1xbet online casino , a tachykinin-like signaling system, regulates sexual activity and fecundity in insects." It appears in the journal Proceedings of the National Academy of Sciences, or PNAS, and was conducted by the Institute of Science and Technology in South Korea; the Slovak Academy of Sciences in Slovakia; Korea 1xbet online casino in South Korea; and Kansas State 1xbet online casino .

1xbet online casino is part of insects' and arthropods' peptidergic system -- a genetic network that uses small peptides as neurotransmitters to chemically relay messages throughout the body.

"1xbet online casino is unique to insects and arthropods and has evolved with them," Park said. "It appears to be related to a neuropeptide called tachykinin that is in mammals and invertebrates. While tachykinin is involved with various biological processes, including the control of blood flow in mammals, 1xbet online casino is linked to reproductive function and mating behavior in insects and arthropods."

The study looks at 1xbet online casino in fruit flies, red flour beetles and silk moths. These insects have four life stages of development -- egg, larva, pupa and adult -- allowing scientists to observe the insects throughout the entirety of their life cycle to find what 1xbet online casino controls.

Kansas State 1xbet online casino specializes in red flour beetle research, while South Korea's Institute of Science and Technology and Korea 1xbet online casino are leaders in fruit fly research, and Slovakia's Slovak Academy of Sciences in silk moth research, Park said.

The researchers saw that in all three insects, 1xbet online casino was expressed in three to four pairs of neurons in the brain.

Using a genetic tool called RNA interference, or RNAi, the researchers looked at what happened when 1xbet online casino was silenced or knocked out from the insects' brains.

They found that the absence of 1xbet online casino in the brain led to the insects' physical inability to reproduce as well as reduced their interest in mating.

"For example, we saw that knocking out the 1xbet online casino in the fruit fly makes them unable to mate," Park said. "The female is too busy grooming her body for the male to approach her. The male doesn't send a strong enough signal to the female to get her attention. We're not sure if that's because the male can't really smell her or because he is not developed enough to signal her."

Park said he anticipates this neuron knockdown will help scientists develop targeted control methods for pest insects that would be environmentally safe. Because 1xbet online casino is only found in insects, a future insecticide would not affect plants, animals or humans.

Additionally, Park said the finding is likely to benefit the scientific community. It sheds new light on how the brain functions with the neurosystem, and provides more information about the basic biology of the fruit fly, which is the model insect for research.

Park's research program has been funded by the National Institutes of Health and the U.S. Department of Agriculture.
