 蚜虫:如何防治蚜虫

蚜虫危害。

许多物种组成了巨大的蚜虫群体,也被称为蚜虫,当树木和灌木的叶子萌发幼芽时,它们就开始觅食活动,对宿主物种造成损害。

有关的昆虫种类包括:绿玫瑰蚜虫( 罗汉果 );夹竹桃蚜虫( Aphis nerii); 柑橘蚜虫( 柑橘蚜虫 );柏树蚜虫( Cinara cupressii );苹果树蚜虫( Dysaphis plantaginea );桃绿蚜(Peach green aphid) Myzus persicae );蜜蜂蚜虫( 蚜虫 ),以及其他许多人。

主持人

蚜虫是一类昆虫,其特点是宿主范围广,包括:冷杉树;李子树;樱桃树;柏树;柑橘树;栒子树;榉树;阔叶树;落叶松树;苹果树;金银花树;梨树;桃树;松树;玫瑰树;郁金香树;椴树等。

诊断

  • 成年昆虫

成虫攻击的特点是在树干和/或树枝上、叶子的背面或一般的针叶上出现虫群。 它们的颜色和形状有不同的色调。 早衰 叶子是一种症状,可以在春季、夏季和秋季观察到。

  • 分泌物

这些害虫的消化,即在消化道层面对植物的浆汁进行加工,导致春、夏、秋三季出现典型的蜜露分泌物(与之相关的烟雾)。 这些含糖的蜜露是蚂蚁的高度追求。

  • 形态学上的改变

叶子的变形,即边缘卷曲,是这些害虫攻击的典型症状,发生在春天、夏天和秋天。

  • 生命周期

这些昆虫每年有几个世代,并聚集在一起形成群落,通常在叶子、茎、花等的背面。

从4月起,在温和的天气中,昆虫通过孤雌生殖繁殖,出现幼虫。 在夏末/秋初,发生有性受精,产卵,该物种以这种形式度过冬季。

一年中最有利于该害虫发展的时期是春季、初夏和秋季。

损害

  • 观赏性

在这些害虫造成的损害中,以下几点比较突出:它们是病毒病的载体;降低光合作用;使芽和叶子变形;导致叶片过早脱落;推迟芽和胚胎的生长;减少开花;降低植物的观赏价值。

  • 生产

就果树生产而言,蚜虫通过使叶子变形并导致它们过早脱落,首先影响了植物的光合速率和能量平衡,从而降低了它们的产量。 请注意,最显著的损害发生在幼苗和/或嫩叶上。

预防

为了防止这些害虫的出现,应该避免严重的修剪;避免夸张的氮肥;选择各种物种进行种植,并为辅助动物,即瓢虫创造条件,因为瓢虫是蚜虫的强大天敌。

监测

监测这些害虫是及时控制它们的一个基本方面。 因此,应注意识别昆虫群落,识别蜜露分泌物和识别全年的蚂蚁攻击。

请注意,属于玫瑰科的植物物种(玫瑰树;李子树;樱桃树;覆盆子树;苹果树;梨树;桃树)更容易受到这些害虫的影响。

控制

如果蚜虫袭击,用洗涤剂和水喷洒(中低强度)。 在袭击强烈的情况下,最好使用经批准的杀虫剂,特别是基于夏季油的杀虫剂。

另一方面,在观赏物种中,现在可以通过微注射技术每年使用杀虫剂。

这些都是非常有利的,首先是在环境层面和对人类的毒性方面,因为所有应用的杀虫剂都保留在植物内部,不与外界有任何接触,因此对气候条件没有影响。

奇闻趣事

蚜虫的攻击特别是在温度高、湿度大的时候。 瓢虫是这种害虫的主要捕食者。
