從測燈和田間調查結果看，稻(dao)(dao)飛(fei)(fei)(fei)虱遷入(ru)分布不均勻，區域間遷入(ru)量差異較大(da)，同(tong)時(shi)，褐(he)飛(fei)(fei)(fei)虱比例(li)和短翅(chi)型成蟲逐步上升。目前早稻(dao)(dao)處于齊穗至灌漿期，營(ying)養條(tiao)件和氣候條(tiao)件將有利于褐(he)飛(fei)(fei)(fei)虱的繁殖為(wei)害，預(yu)測早稻(dao)(dao)后期褐(he)飛(fei)(fei)(fei)虱將偏(pian)重發生，局部重發生。各地(di)要(yao)密切關注稻(dao)(dao)飛(fei)(fei)(fei)虱發生動態，準確預(yu)報，科學防控，確保水(shui)稻(dao)(dao)生產安全。
