看起来那么美丽的夜合花也不是没有烦恼的，危害植物的虫害也会发生在夜合花的身上，下面，小编就教一下大家，如何防治夜合花的常见虫害！

夜合花的蚜虫防治

1.家里应该都会有些辣椒之类的吧，有的话可以用鲜辣椒或干红辣椒50克，加水30至50克，煮半小时左右，用煮完过滤后的滤液喷洒受害植物，效果很不错哦！

2.如果没有辣椒的话，那么就可以用家里常用的洗衣粉3至4克，加水100克，搅拌成溶液，连续喷撒植株2至3次，防治效果甚至可以达100%！

3.夏天到了，风油精也渐渐的出现在人们的视线里，用“风油精”加水到600至800倍溶液，用喷雾器对害虫仔细喷洒，让害虫的身体沾上药水。杀灭蚜虫及介壳虫等害虫的效果都在95%以上，并且对植株不会产生药害，很好用的哦~

4.将洗衣粉、尿素、水按1：4：100的比例，搅拌成混合液后，用其喷洒植株，可以灭虫、施肥，这可是一个一举两得的好方法哦！

夜合花的介壳虫防治

1.用家中的白酒兑上水，比例为1：2。治虫的时候要记得浇透盆土的表层。介壳虫在春季室温7℃时，便开始活动，我们可以瞅准了时机，在4月中旬的时候浇一次药水，之后每隔半个月左右就浇一次，连续浇上四次之后就能够见到效果。

2.用食醋，最好是米醋，50毫升，将小棉球或者是棉签放进去浸湿后，用湿棉球或棉签在受到了虫害的夜合花茎、叶上轻轻地擦拭，就可以将介壳虫擦掉杀灭。这个方法比较安全，既能达到除虫的目的，又可使被害的叶片重新变得绿意盎然，只是如果夜合花大面积的遭受介壳虫的话，可就有些费力气了。

3.用酒精轻轻地反复擦病株，不但能把介壳虫除掉，就是肉眼看不清楚的幼虫，也都可以彻底杀灭掉，而且第二年很少发现有介壳虫的危害。不过和第二个方法一样，如果是大面积的遭受侵害的话，这个方法就会有些费力气。

4.也可以用柴油、洗衣粉、水按10：0.6：6的比例调成杀虫液，最后调成的杀虫液呈牛奶状，用水稀释后，对夜合花身上的介壳虫仔细喷洒。大概一周的时间，介壳虫中的大部分就会变得干瘪死去。

夜合花的其他虫害防治

对于其他的比如叶甲等，可以使用50%杀螟松乳油1000倍液喷杀。

其他的诸如蚜虫和介壳虫也可以用这个方法来灭杀。

不过，如果有条件的话，还是建议大家用以上的那些高效安全的灭虫方法哦！
