Pesky Treehoppers: Controlling Leafhopper Infestations

你的花园发芽、成长,如果你像me, you’re monitoring each little sprout, rejoicing in the possibilities. Unfortunately, there are bugs that are doing the same thing. Like those sneaky leafhoppers.

如果你进入自然害虫控制，看看这些提示!

多年来，我与叶蝉有一场长期的战斗。看起来这场战斗将在夏威夷继续在这里。叶蝉逐渐变化（有些是绿色的，有些是棕色，有些是Reddish），但他们生活在世界各地的每个地区。我也听说过他们planthoppers. These pests suck plant sap from the stems and can introduce pathogens as they do so.

What I have here seem to betreehoppers. Treehopper nymphs don’t move much at all. While adult treehoppers are fast, the nymphs don’t fly or move quickly. Identifying leafhoppers at this stage allows me to kill them easily, targeting them before they do more damage or reproduce.

Leafhoppers — damage to plants

Notice the brown stems in the photo above. That’s damage from treehoppers. This damage doesn’t kill the plants immediately, but it does weaken them. My aim is to reduce the population enough to prevent total devastation to the plants.

Sometimes gardeners don’t identify an infestation until it’s quite advanced. At that point, you’ll notice that disturbing a plant causes adult treehoppers to fly up in a cloud of little bugs, hopping from leaf to leaf. Upon closer inspection, you’ll see the beginning of damage on plants.

Those adults will spread out amongst your vegetable plants and procreate, so ideally you want to remove thembeforethat can happen. Which means finding leafhoppers at the egg or nymph stage.

Manual control of leaf hopper bugs

Adult leafhoppers or treehoppers are difficult to catch, but they are a signal that you’ve got trouble. If you see adult treehoppers, keep an eye on your vegetable plants for eggs and nymphs. Check the underside of leaves for eggs. The nymphs will be visible on thick plant stems. I find that nightshade plants are particularly desirable to the treehoppers we have here.

If you’ve got the time, you can reduce the risk of leafhopper damage by keeping an eye on the underside of your plants’ leaves for小白蛋.

How to Plant Food in Your Backyard for a Healthy Harvest

If you find them, carefully brush them off, making sure to smash them. I do this with my fingers; it’s too hard to be gentle while wearing gloves. I’ve eradicated a large number of eggs from young seedlings.

To kill leafhoppernymphs, I use gloved hands, smashing them between my thumb and forefinger. (Bare hands can work, but the nymphs are a bit thorny and can hurt tender fingers.) This method has been the most successful.

A good dusting of diatomaceous earth as soon as I suspect trouble is always my first line of defense fornatural pest control.Spraying the plants with water and insecticidal soapis another option.
