After mosquitoes, genetically modified technology makes moth populations disappear.

For a long time, small vegetables have been considered a destructive agricultural pest.
years, the only way to solve the pests of small vegetables was through the use of pesticides and pesticides.
now, that may change.
may be the second population to disappear after gene-editing technology allowed all the world's mosquitoes to go extinct.
a genetic engineering technique recently proposed by Cornell University has been approved by the U.S. Department of Agriculture and is about to be tested in a small part of upstate New York.
that the technology could eventually disappear by genetically modified moths.
is understood to be responsible for the "production" of genetically modified moths by Oxitec, a subsidiary of British biotech group Intrexon.
the company designed the male cauliflower with a "self-limiting gene."
that when the male cauliflower mats with the female, the gene is passed on to the offspring.
this gene allows female and male cauliflowers to die before they reach adulthood, making it impossible to reproduce.
, scientists say, could reduce the number of moth populations in the area where genetically modified small vegetables are placed and further protect crops from damage.
addition, the cauliflower is labeled with fluorescent protein for easy tracking and monitoring.
, an entomologist at Cornell University, led the experiment.
said the field trials were aimed at getting more information about how these genetically modified insects could be used in pest management in the future.
shelton and his team are expected to release a batch of genetically modified courgets on a 10-acre site at Cornell University in Geneva, New York.
, with the permission of federal agencies, they can release up to 10,000 male moths at a time, or up to 30,000 pythons a week for a period of three to four months.
however, the GM technology used in the trial has caused public interest and anxiety between many people.
, more and more institutions are using GM technology more widely in agriculture.
, many academic and commercial researchers are beginning to expand genetic technology from the field of plants to the world of insects.
Hansen, a senior policy analyst at the Center for Food Safety in Washington, D.C., expressed concern between consumer advocacy groups that the use of genetically modified moths might not reduce pesticide and pesticide use.
" and other insects also eat these vegetables.
if we still have to spray chemicals to kill other pests, what's the use of just eliminating small vegetables? Oxitec has previously used the same technology to "produce" male Aedes aegypti mosquitoes to prevent certain mosquito-borne diseases, such as Zika, dengue and yellow fever.
last year, the company launched genetically modified mosquitoes in parts of Brazil, Grand Cayman and Panama, where it said the number of Aedes aegypti mosquitoes had declined.
and federal agencies gave the test a "green light" because they believed that small-scale farm tests were unlikely to pose a risk to the environment or human health.
'll see how it works.
