了解这种害虫的主要特征以及如何防治。

布拉格

黑煤油 ( Saissetia oleae Olivier ).

特点

这是一种蛤蚧,体长3-5毫米,颜色为深棕色/黑色,形状为椭圆形(雌性),身体凸起,背面似乎写有字母H。 卵长约0.3毫米,呈椭圆形,开始时为粉红色,结束时略呈黄色。

生物周期

这种昆虫每年有两代(柑橘),在橄榄树上有一代。 每只雌虫通过孤雌生殖,可以产下大约1000-2500个卵,聚集在一个盾牌(母体)下,这个过程在6月份大约需要15-30天。 由于我们的气候条件,死亡率可以达到80%。 存活的扁平、椭圆形、黄褐色的幼虫会附着在橄榄树上。它们附着在组织上,一直发育到春天,当它们达到成年时(初夏)。

第二代在秋季开始繁殖,以未成熟的雌性身份度过冬季。 大气中的低湿度和高日照会增加这种害虫的死亡率。

更加敏感的植物

橄榄树、橘子树、月桂树和一些观赏性树木。

损害

它们出现在枝叶上。 蛤蚧沿着中脉附着在下页,然后移动到枝条上,吸食植物的汁液,这可能导致果实产量降低。 被攻击的枝条会干枯和倒下,削弱植物。 产生的蜜露会呼唤蚂蚁,蚂蚁会刺激蛤蚧产生更多蜜露,随之出现更多的蜜露。富马酸会加剧对树木(呼吸功能和光合作用)的损害,并影响其生产。

生物控制

预防/农业方面

修剪,以便有利于树冠内的光照和空气流通;(在冬季)剪掉害虫大量存在的枝叶;减少氮肥。

生物化学战

应该在7月至10月(橄榄树)和2月至3月(柑橘)进行,喷洒夏季油--它可以阻止产卵--应该在秋季开始时对整棵树进行;应用 "楝树"(一种天然来源的物质),对这种害虫有驱赶作用;用钾肥皂和酒精制成溶液,喷洒在蛤蚧身上,并将其清除。你应该从5月起进行这些治疗。
