Grasshoppers Are Painful Citrus Pests
There are few more well-known heralds of spring than the grasshopper. Heading out into the yard and seeing these massive insects hopping from place to place is sure to bring a smile to your face unless they're chomping down on your citrus trees.
Grasshoppers start by chewing the leaf edges and move inward until only the primary vein is left. A few can be an annoyance, but grasshoppers can be prevalent by the thousands. They can strip entire small trees bare and have been the bane of many farmers.
Caterpillars are Not Just Butterflies
Caterpillars are even more beautiful than grasshoppers and they turn into moths and butterflies. What can be better than that? Many species of caterpillars eat citrus trees. They eat the leaves and shoots of young trees. The leaves can also be rolled and webbed.
The transformation into a butterfly may be attractive, but the damage done in preparation can be a nightmare for citrus growers. They feed on the leaves before entering their cocoon or web.
Citrus Leafminer Digs Into Leaves
The citrus leafminer isn’t looking for gold in the leaves like traditional miners and that’s bad news for citrus growers.
Just like miners, they dig tunnels under the surface of leaves that are either pale or black. Black tunnels are filled with excrement. You’ll notice the tunnels and leaves can be galled, rolled or distorted.
Citrus Whitefly Attracts Other Insects
Many citrus insects are easily spotted because they leave their marks on top of the leaves or chew the entire leaf. The citrus whitefly is sneakier and only eats the bottom of the leaves. They also lay their eggs and the larvae suck the sap from the leaves.
They excrete a substance called honeydew, unmetabolized sugar from the sap that sticks to the leaves and attracts other insects such as ants.
If you want to know if you’ve got a citrus whitefly infestation, just shake a few branches. The small white insects will detach and flutter around the tree.
Citrus Thrips Attack Leaves and Fruit
These yellow or orange insects do more than just damage leaves, they also attack young fruit. They want the tree sap and also lay their eggs. The larvae eat the leaves and fruit, especially during periods of hot weather with little moisture.
You’ll notice a citrus thrip infestation if you see silvery or scabbed fruit and silver-grey leaves that are curled or distorted.
Bounce Back From Tree Pests
These are only a few of the many citrus pests that can plague an orchard. Small young citrus fruit trees are the most vulnerable and those stressed by drought or disease. Learn the signs of these pests and protect your trees from citrus tree diseases.
