RT, 最近发现总有一种绿色虫子啃食花坛中植物的叶子, 叶子上留下很多窟窿, 这种绿虫叫什么名字? 如何消灭? 谢谢!

Protect your flower gardens, roses and trees from Aphids with live Lady Bugs. This package includes 1000 live Lady Bugs to cover up to 10 sq. meters. When released into your garden -preferably at night - the adult Lady Bugs feed and reproduce by laying eggs. Once these eggs hatch, hungry Lady Bug larvae keep your pests at bay!

An excellent general predator! Praying mantis consumes aphids, beetles, flies, mosquitos, moths, caterpillars and any insect they can catch. Praying mantis, an insect with an innate killer attitude, is a great garden predator. One egg case hatches many tiny babies that quickly disperse throughout your garden. Your egg case contains approximately 40 to 400 eggs.

Mating occurs in early fall and another egg case will be laid that will hatch the following summer. The egg case is laid as a foam that hardens into a spongy almost indestructible mass, usually laid attached to a shrub, weed, grass, etc., a few feet off the ground. The egg mass survives freezing, thawing, rain and all the elements to hatch in the early summer to start the cycle again.
 
谢谢胖嫂子,我不太明白的是要用这两种活物来杀虫子吗?这两种东西将来会不会搞得到处都是呢?

七星瓢虫和螳螂都是杀虫高手,不污染环境(环保),七星瓢虫可活3-4个月,你的garden吃完,就飞到其它garden。我想活不过冬天的。但我发现它cover很大一片,garden小,值不值得买。

谢谢,谢谢! garden着实不大,不知还有其他办法没有。。。花种在盆里的时候没发现虫子,种到garden以后我怀疑是mulch里有虫蛹吧,放了mulch没几天就被虫咬了。
 
不客气,去HD和lows问一下,他们经验丰富,也许能帮上忙。
 
用很稀的洗碗液(Ivory or Dove dish soap, not dish detergent)喷到菜叶上。

七星瓢虫最喜欢吃 lily的叶子. 如果有Lili, 每天要案检查一下, 不然叶子很快就吃光了.
 
种花也真不容易,要了解不少东西。

这个一定要很稀很稀,多稀要专家解释。去年不够稀,喷死一株芍药:mad:
