Сирдарё вилояти шароитида подура Podura aquatic ҳашаротининг биологияси тўғрисида

Подурада қанотлар ривожланмаган. Улар оёқлари ёрдамида ҳаракатланади, орқа оёқлари ёрдамида сакраб харакат қилади. Подураларнинг 1-3 ёшдаги личинкалари ўрмалаб ҳаракатланади. Личинкаларнинг 4-5 ёшдаги формалари орқа оёқлари билан ҳам ҳаракатланади. Личинкаларининг терисида жуда кўп туклар жойлашган. Узоқ вақт нам бўлган шароитда тарқалган. Шунинг учун уларнинг личинкалари намлиги юқори  бўлган тупроқларда фаол бўлади. Личинкалар тупроқнинг 5 см дан 30 см гача бўлган чуқурликдаги юмшоқ қатламларида учрайди. Тухум қўйиш билан кўпаяди. Тухумини 3 см чуқурликка қўйиб, самкаси тухумини ёпиб қўяди. Тухумидан майда личинкалар чиқади. Личинкалар тупроқдаги лишайник, бактериялар колонияси, ўсимликларнинг органик қолдиқлари ва замбуруғ споралари билан озиқланади. Подуралар ва уларнинг личинкалари -5, -15 C0 хароратда ҳам харакатда бўлади. Совуққа чидамли. личинкалари тупроқдаги бактерия ва замбуруғ колониялари билан озиқланиши билан бирга қишлоқ ҳўжалик ўсимликлари орасида замбуруғли ва бактериал касалликларни тарқатади. Натижада, ўсимлик ер устки қисмининг зарарланган жойига микроорганизмлар спораси ёпишиб, ўсимликни зарарлайди.
