软枣猕猴桃主要虫害和防治方法

Species and Control Methods of Main Pests of Actinidia arguta. P

软枣猕猴桃栽培过程中,会遭受多种害虫的取食,生产中了解害虫的发生规律,对于有效防治害虫,保证产量和品质至关重要。文章中介绍了刺吸式口器害虫(蝽象、叶蝉蜡蝉、介壳虫、叶螨)和咀嚼式口器害虫(金龟子、透翅蛾),其中,蝽象以成虫和若虫取食为害,以化学防治为主,采用拟除虫菊酯和新烟碱类广谱性杀虫剂防治;在叶蝉卵孵化期或若虫盛期,可喷施50%杀螟松乳油、20%害扑威乳油进行防治;蜡蝉类成虫和若虫善跳跃,在发生期用菊酯类杀虫剂防控效果好;介壳虫掌握在若虫孵化和移动期防治效果最好,可选用螺虫乙酯、噻嗪酮、噻虫嗪等;螨类主要有山楂叶螨、二斑叶螨等,药剂可选择噻螨酮、阿维菌素、乙唑螨腈等;防治金龟子可利用其趋光性,用黑光灯诱捕;防治软枣猕猴桃透翅蛾可以人工及时剪除虫枝及茂密枝,并集中烧毁,减少虫源,也可选用拟除虫菊酯类农药喷雾防治。

Actinidia arguta cultivation process,will suffer from a variety of pests to feed,production to understand the occurrence of pests,for effective pest control,ensure yield and quality is very important.In this paper,stinging and sucking mouthparts pests(bugs,leafhoppers,cerascicadas,scale insects,tetranychus mites)and chewing mouthparts pests(scarab beetles,hymenoptera)were introduced.Among them,the bugs were mainly affected by the feeding of adults and nymphs,and the chemical control was mainly used to control them by pyrethroids and neonicotinoids.In the leafhopper egg incubation period or nymphs peak,can spray 50%borer pine oil,20%benbubub oil for control;The adult and nymph of cicadas are good at jumping,and pyrethroid insecticides have good control effect in the occurrence stage.The control effect of scale insect is best in the nymphal incubation and migration period,and spiroworm ethyl ester,thiazinone,thiamethoxam and so on can be selected.The main mites are hawthorn tetranychus mites,two spot tetranychus mites,etc.,agents can choose thiacarone,avermectin,ethoxazole acaronil,etc.Control chafer can use its phototaxis,with black light lamp trapping;Prevention and control of soft date kiwifruit through the wing moth can be artificial timely cut off insect branches and thick branches,and centralized burning,reduce insect source,can also choose to control pyrethroid pesticide spray.
