Annotatsiya. Ushbu maqolada moyli ekinlarda uchraydigan Meloidogyne
avlodiga mansub ildiz gall nematodalarining bioekologik xususiyatlari tahlil qilinadi.
Meloidogyne spp. polifag o‘simlik-parazit nematodalar bo‘lib, ular kungaboqar, soya,
yeryong‘oq, kunjut, raps va boshqa moyli ekinlarning ildiz tizimida g‘uddalar hosil
qiladi, suv va mineral moddalar o‘zlashtirilishini susaytiradi hamda hosildorlik va
mahsulot sifatining pasayishiga olib keladi. Maqolada nematodalarning morfologik
belgilari, rivojlanish sikli, tuproq-iqlim omillari bilan bog‘liqligi, ekin turi va
almashlab ekish tizimining ta’siri, zararlanish belgilari hamda ekologik xavfsiz
boshqarish yo‘llari yoritilgan. Surxondaryo viloyati sharoitida issiq iqlim,
sug‘oriladigan dehqonchilik, yengil va o‘rtacha mexanik tarkibli tuproqlar
Meloidogyne populyatsiyalarining rivojlanishida muhim omil bo‘lishi mumkin.
