Green bugs on plants: Complete guide with photos

How are you gardeners? In today’s post, the protagonists will be the green bugs . Yes, only the greens … another day we will look at more colors. They usually camouflage themselves well, but we, who are on our way to being expert entomologists… We will be able to identify them all!

Green bugs on plants

Not all green bugs that we see on our plants are considered pests . A pest is those organisms that produce economic losses by reducing the availability, quality or value of some cultivated resource for food, fiber, pleasure or health. Also, it can be defined as any organism whose population density exceeds a previously established threshold.

Once we are clear about this concept, we can begin to identify the green bugs in our plants and know if we should apply a treatment or not.

Green aphids

The aphids are green bugs best known and one of the most common pests of orchards and gardens. They are small insects (1-3 mm in length) and can present different colors depending on the species to which they belong.

Damage from aphids

Most are polyphagous, that is, they do not have a preference for a specific plant species. They attack young shoots of crops with high sugar content.

The larvae cause damage by making galleries in the leaves of the plants . As for adults, they feed by sucking the sap from leaves, buds and young shoots using the stylet of their mouthparts. In addition, they excrete a sugary and sticky liquid called molasses that attracts ants (aphids are said to be herders of ants  because they protect them and drive towards food). They favor the appearance of a fungus known as bold and can also transmit viruses from one plant to another.

Aphid control

Eliminate weeds, good substrate preparation, color traps, pruning or natural enemies such as ladybugs, lacewings, earwigs or wasps.

Green bug

They are known as green bug or garden bug , among others. They are very common in hot countries. The eggs of these bugs are generally deposited on the underside of the leaves and are barrel-shaped, creamy yellow, which later evolves into pinkish-orange.

Nymphs, in their first stages, are orange in color and begin to be green in the fifth stage. The adults are green, although small yellow spots can be seen on the gusset. In addition, they have a chopping-sucking mouthpart.

Green bug damage

They can be a pest of all kinds of horticultural plants, fruit shoots, vineyards and ornamental plants such as gladiolus. These types of insects suck sap or juices from leaves, shoots and fruits, and inject saliva that causes tissue damage. For example, in tomato growth stops at the point of the bite, forming cracks, deformations or a whitish circle around it.

How to control the green bed bug

To control this type of bed bugs, good irrigation management is essential, avoiding excessive humidity. We can put light traps at night to attract adults. Some spiders and ants are predators of the green bug and will help control it in the garden. In addition, we can use trap plants such as beans to attract this type of insects to them.

Orthoptera (grasshoppers, crickets, …)

Grasshoppers, crickets or locusts belong to this group . Orthoptera are characterized by being good jumpers and some good fliers. They carry out the laying on the ground or on the plant. Normally they lead an isolated life, although they can present phenomena of gregariousness as in the case of lobsters.

There are various methods to control this group of insects. Highlight the biological control through predators, parasitoids and fungi. In the case of lobsters, there are special programs for their surveillance and control.

Beetles 

Cassida sp

From the family of chrysomelids. The larvae, usually flattened, are green with lateral spines and two appendages on the eighth segment. It is usually covered with exuvia and excrement. Both adults and larvae feed on the parenchyma and can defoliate (leave no leaves) the plant.

Mint beetle

Measures 7-11mm in length. They are bright green, with black legs and antennae. Both adults and larvae feed exclusively on mint, which can become a dangerous pest. They mainly attack the leaves and stems.

Other more peculiar green critters

Praying mantis

There are other green insects, such as the Praying Mantis, that are not a concern for the garden. The Praying Mantis is a predator of insects and, as a curiosity, there is a martial art inspired by its way of attacking prey.

Stick insects and leaf insects
