稻瘿蚊(Orseoliaoryzae(Wood-Madon)是江西赣南稻区1种重要水稻害虫,受害田一般减产10%~20%,严重田块基本无收。研究表明:田间稻瘿蚊标葱消长,一季稻早熟类型田呈单峰型,中、迟熟类型田均呈双峰型;二季晚稻也为双峰型。药剂防治适期为秧苗移栽结束后,即蚊卵盛孵期。药剂防治策略为轻发年不治秧田,挑治本田;中发年挑治秧田,普治本田;重发年秧田本田普遍治,重点治秧田,保大田。
Orseolia oryzae (Wood-Madon) is one of the most important rice pests in southern Jiangxi Province. The affected fields generally reduce the yield by 10% ~ 20%, and there is no yield in serious fields. The results show that: The type of early rice in one season was single peak, middle and late type showed bimodal type, the second season late rice was also double peak type, and the suitable period of medicament control was after the transplanting of seedling, that is, the incubation period of mosquito and eggs. Strategy for light years without treatment of seedling, pick and cure Honda; in the hair pick pick seedling, Purcell Honda; re-year seedling Honda universal rule, focusing on seedling control, security Dae Tian.
