摘要
为了明确冀北地区大豆田害虫发生规律和提高害虫防治水平,综合多地区大豆田害虫调查结果,分析了河北省春播区大豆害虫的发生规律,结果表明,害虫种类多,在大豆全生育期共发生害虫30种,分属6目17科;为害严重,大豆蚜、点蜂缘蝽等害虫均可造成大豆严重减产甚至绝产;防治难度大,棉铃虫等一些害虫为害具有暴发性,需短时间内作出防治反应,点蜂缘蝽等一些害虫为害时间长,需进行多次防治。根据害虫发生规律和为害程度,进一步将害虫分为3个等级并提出了相应的防治措施。同时针对春播大豆害虫防治中存在的一些问题提出了建议。
To clarify the occurrence pattern of pests in soybean fields in Northern Hebei and improve pests control,this paper analyzed the occurrence of pests in soybean fields in the spring sowing area of Hebei based on the results of multi-areas survey.The results showed that many species of pests,a total of 30 species of pests belonging to 6 orders and 17 families,occurred throughout the whole growth period of soybean.Some pests such as Aphis glycines,Riptortus pedestris could cause serious yield reduction or even extinction of soybeans.It was difficult to control because some pests such as Helicoverpa armigera need to be controlled in time and some pests such as R.pedestris with long damage time need to be controlled several times.According to the pest occurrence pattern and degree of damage,the pests were further divided into three classes and corresponding control measures were proposed.Meanwhile,suggestions were made for some problems in the control of spring soybean pests.
