These insects, which do not sting or bite, also act as a food source for birds. <\/p>\n<p class=\"font-body-baseline-regular text-primary\" data-testid=\"article-paragraph-annotation-test-id\">However, male cicadas are one of the loudest insects in the world when they mature into adults.<\/p>\n<p class=\"font-body-baseline-regular text-primary\" data-testid=\"article-paragraph-annotation-test-id\">Said entomologist Foo Maosheng, insect curator of NUS\u2019 Lee Kong Chian Natural History Museum: \u201cIf you imagine the trees as a dating scene, the males are trying to outcompete with each other in order to attract mates. <\/p>\n<p class=\"font-body-baseline-regular text-primary\" data-testid=\"article-paragraph-annotation-test-id\">\u201cBecause there are so many of them competing with each other, they tend to find quieter spaces, inevitably winding up in residents\u2019 homes as they use lights to navigate.\u201d<\/p>\n<p class=\"font-body-baseline-regular text-primary\" data-testid=\"article-paragraph-annotation-test-id\">To control the cicadas\u2019 numbers in an environmentally sensitive manner, the five-month trial will disrupt their life cycle at hot spots. <\/p>\n<p class=\"font-body-baseline-regular text-primary\" data-testid=\"article-paragraph-annotation-test-id\">This was planned with the support of the National Parks Board and <!-- -->Mr<!-- --> Foo<!-- -->, who is helping to study the cicadas<!-- -->.<\/p>\n<p class=\"font-body-baseline-regular text-primary\" data-testid=\"article-paragraph-annotation-test-id\">The plan is to encircle 120 trees with mats to prevent the cicadas \u2013 which spend their time as nymphs underground \u2013 from entering or emerging from the soil, as well as to cover the tree trunks with aluminium foil to prevent nymphs from climbing onto them.<\/p>\n<p class=\"font-body-baseline-regular text-primary\" data-testid=\"article-paragraph-annotation-test-id\">This<!-- --> will be completed by mid-March, when the current season is slated to start, said Mr Choo.<\/p>\n<figure class=\"landscape inline-media-wrapper\" data-testid=\"inline-media-test-id\">\n<div class=\"flex flex-col items-start relative w-fit\"><picture><source media=\"(max-width:

data-testid=\"article-paragraph-annotation-test-id\">While the other 10 species of cicadas found in Singapore are known to live for up to six years, spending most of their life underground, it is

CHNG<\/p>\n<\/figcaption><\/figure>\n<p class=\"font-body-baseline-regular text-primary\" data-testid=\"article-paragraph-annotation-test-id\">Another key part of the study will look at how the cicadas arrived in Tampines Changkat, seemingly out of the blue, by analysing how usage of the land has evolved over the years.<\/p>\n<p class=\"font-body-baseline-regular text-primary\" data-testid=\"article-paragraph-annotation-test-id\">While the species is native to South-east Asia, the only other country it has been confirmed to inhabit is the Philippines. <\/p>\n<p class=\"font-body-baseline-regular text-primary\" data-testid=\"article-paragraph-annotation-test-id\">One theory for the swarms\u2019 sudden emergence is an imbalance in the ecosystem, said Mr Foo, noting that long-time residents reported issues in recent years. <\/p>\n<p class=\"font-body-baseline-regular text-primary\" data-testid=\"article-paragraph-annotation-test-id\">Also driving the initiative is a new Nature Kakis chapter for Tampines Changkat \u2013 comprising grassroots leaders and residents \u2013 to help in the research, monitoring and implementation of measures to control the cicada population.<\/p>\n<p class=\"font-body-baseline-regular text-primary\" data-testid=\"article-paragraph-annotation-test-id\">Among the pioneering Nature Kakis team members is Ms Khalisah Shari, 23, who <!-- -->has lived in the estate all her life and <!-- -->has had her sleep disturbed by cicadas repeatedly pelting themselves against her windows. <\/p>\n<p class=\"font-body-baseline-regular text-primary\" data-testid=\"article-paragraph-annotation-test-id\">The National University of Singapore <!-- -->student<!-- --> said: \u201cIt can be quite a disturbance \u2013 the high-frequency noises they make, and how they fly around the lights. <\/p>\n<p class=\"font-body-baseline-regular text-primary\" data-testid=\"article-paragraph-annotation-test-id\">\u201cBut I also don\u2019t want the solutions (to curb them) to be invasive for the environment, so I wanted to be part of the effort to make the estate a better place.\u201d<\/p>\n<p>A reading taken by The Straits Times with a sound level meter found that combined noise levels from the expressway and cicada calls before the insects\u2019 peak season reached 72.5 decibels on the highest floor of one of the affected blocks. The volume fell to 62.3 decibels on the ground floor.<\/p>\n<p>This was in contrast to the calm of 48 decibels outside the open-air multipurpose hall, where the March 1 town hall was conducted, which is a minute\u2019s walk away from the block.<\/p>\n<\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/www.straitstimes.com\/singapore\/environment\/multi-year-study-launched-to-crack-tampines-changkats-mysterious-cicada-woes\" target=\"_blank\" rel=\"noopener\">Read Full Article At Source <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>SINGAPORE \u2013 A years-long study to understand and control the mysterious emergence of hundreds of cicadas near HDB blocks in Tampines Changkat is under way&#8230;.<\/p>\n","protected":false},"author":1,"featured_media":32809,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"","fifu_image_alt":"","footnotes":""},"categories":[2611],"tags":[],"class_list":["post-32808","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-buzz-headlines","wpcat-2611-id"],"_links":{"self":[{"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/posts\/32808","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=32808"}],"version-history":[{"count":0,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/posts\/32808\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/media\/32809"}],"wp:attachment":[{"href":"https:\/\/sgbuzz.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=32808"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=32808"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=32808"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
