According to scientists, the transgenic technology may soon prove obsolete. Until a decade ago, scholars had no doubts: the extension of Bt-corn fields in the U.S. led not only to an increase in <strong>crop yields<\/strong>, but also to a marked reduction in the need to use <strong>pesticides-even<\/strong> on neighboring land used for other crops-with an obvious saving in resources. But the new study, signed by 20 scientists from 18 global institutions, seems to dampen enthusiasm somewhat. Led by Ziwei Ye, a professor at <strong>Renmin University of China<\/strong>, the scholars examined data from 12 years of field trials in 10 Midwestern states of the so-called <strong>Corn<\/strong> Belt (&#8220;corn belt&#8221;). Their research shows that farmers are using too much Bt corn seed (engineered with insecticidal substances obtained from <strong>Bacillus thuringiensis<\/strong> to protect plants from pest attacks), resulting in the corn <strong>rootworm be<\/strong> etle<em>(Diabrotica virgifera virgifera<\/em>) to be combated <strong>developing resistance<\/strong>, undermining the effectiveness of the transgenic technology.     <\/p>\n\n<div style=\"height:43px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-fe48e5de wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/www.ilfattoquotidiano.it\/2025\/03\/19\/ogm-science-mais-transgenico-ha-rafforzato-coleottero\/7903239\/\" target=\"_blank\" rel=\"noreferrer noopener\">read the full article<\/a><\/div>\n<\/div>\n\n<div style=\"height:43px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"637\" src=\"https:\/\/org.wwoof.it\/wp-content\/uploads\/2024\/02\/mais-ogm-1024x637.jpg\" alt=\"corn-ogm\" class=\"wp-image-17271\" style=\"width:648px;height:auto\" srcset=\"https:\/\/org.wwoof.it\/wp-content\/uploads\/2024\/02\/mais-ogm-980x610.jpg 980w, https:\/\/org.wwoof.it\/wp-content\/uploads\/2024\/02\/mais-ogm-480x299.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1024px, 100vw\" \/><\/figure>\n\n<div style=\"height:43px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n","protected":false},"excerpt":{"rendered":"<p>farmers are often uninformed about the long-term implications of using such hybrids<\/p>\n","protected":false},"author":3,"featured_media":21652,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_et_pb_use_builder":"off","_et_pb_old_content":"","_et_gb_content_width":"","wds_primary_category":0,"footnotes":""},"categories":[1450,1720],"tags":[1569,4498,5584,4801],"class_list":["post-22051","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-from-our-networks","category-news-en","tag-corn","tag-ogm-en","tag-pests","tag-resistance"],"_links":{"self":[{"href":"https:\/\/org.wwoof.it\/en\/wp-json\/wp\/v2\/posts\/22051","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/org.wwoof.it\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/org.wwoof.it\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/org.wwoof.it\/en\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/org.wwoof.it\/en\/wp-json\/wp\/v2\/comments?post=22051"}],"version-history":[{"count":3,"href":"https:\/\/org.wwoof.it\/en\/wp-json\/wp\/v2\/posts\/22051\/revisions"}],"predecessor-version":[{"id":22054,"href":"https:\/\/org.wwoof.it\/en\/wp-json\/wp\/v2\/posts\/22051\/revisions\/22054"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/org.wwoof.it\/en\/wp-json\/wp\/v2\/media\/21652"}],"wp:attachment":[{"href":"https:\/\/org.wwoof.it\/en\/wp-json\/wp\/v2\/media?parent=22051"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/org.wwoof.it\/en\/wp-json\/wp\/v2\/categories?post=22051"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/org.wwoof.it\/en\/wp-json\/wp\/v2\/tags?post=22051"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
