AQShning sharqiy hududlarida bahor kelishi bilan 17 yillik uyqudan keyin yer ostidan chiqayotgan ko‘plab hasharotlar qayd etildi. Mazkur zararkunandalar baland va noxush tovush chiqaradi. Shuningdek, ular uzoq umr ko‘rishi (13—22 yil) bilan boshqa hasharotlardan ajralib turadi.
Ta’kidlanishicha, hasharotlarga Brood X deb nom berilgan. Hozirgi kunda ular Amerikaning 18 ta shtati bo‘ylab tarqalgan. Michigan va G‘arbiy Virjiniyada zararkunandalarning eng ko‘p soni qayd etilgan.
Mutaxassislar bir gektar yerda, taxminan, bir yarim million hasharotlar paydo bo‘lganini hisoblab chiqdi. Bundan kelib chiqadiki, AQShda bir necha o‘n milliard zararkunandalar mavjud.
Agar kelgusi bir necha hafta ichida hasharotlarning ko‘payishiga chek qo‘yilmasa, u holda mamlakat “sikad gilami” bilan qoplanadi.
So‘nggi kunlarda hasharotlar o‘rmon va bog‘larga quvib yuborilmoqda, bundan mahalliy aholi xursand.
.@JERutter and I finally got to see our first of the Brood X #cicadas this morning.

I captured this 4.5 hour time lapse of its transformation from nymph to adult.
SO. DANG. COOL. pic.twitter.com/tgA0vqP4IW
You might have seen the #cicadas already but did you stop for over an hour or 2 to see how the nymphs become adults?
