Melolontha and other parasites of roses

We continue to discuss the topic of the fight against pests of roses. Today we will discuss some roses parasites and how to get rid of them.

Bedbug, or meadow

Pretty large insect of flat form. It is gray, greenish or reddish brown. They are thrusting sucking insects, which means they also feed on the cell sap of plants. The bugs are damaged by leaves and buds and are not averse to biting the flowers themselves.

Methods of combating the bug

With a small presence of bedbugs, they can be collected manually. Also, hunters’ belts from cardboard, smeared with office glue and covered with a layer of glass wool in 1,5 cm, which you can do yourself or buy in garden centers, will help. However, they are not very aesthetic. Insecticides and pesticides of systemic action will help in the struggle, as well as folk methods. For example, household solution. soap – 300 g per 10 liters of water; onion infusion – 200 g of onion peel infuse in 10 liters of water for 5 days and spray the plants; 100 g of dried Sarept mustard and 10 liters of water.

Meadow froghopper

She lives inside the lumps of foam on the stems and leaves. These larvae feed on the juice of the plant. If the larvae are severely affected, the stems are deformed and the leaves partly fall.

Methods of treatment from Meadow froghopper

In case of damage to individual stems, it is sufficient to remove the foam. If there are many such cuckoo tears, it is necessary to wash the plant first with a water jet. After that, treat the bush, for example, with permethrin.

Aulacaspis rosae

Aulacaspis rosae is covered with a white “shield” and settles on the stems of plants. Usually on old stems, when it appears, it is possible to find small scales similar to dandruff. They spoil the appearance of the plant, and the insects under them weaken it.

How to treat an Aulacaspis rosae

With a small lesion, the pest shields can be smeared with methylated alcohol. If the rose is severely affected, it is necessary to sprinkle abundantly with preparations containing bifétrin.


The most famous pest is ants. They loosen the soil around the roots, as a result of which the plant begins to wilt and may die. Means of fighting against these insects are sold in every garden store.


Melolontha belongs to the family of lamellites. There are two types: western and eastern. The larva of the May bush is also a dangerous pest of roses. They feed on the roots of roses, and this greatly weakens the plants and can even lead to its death.

Treatment from the Melolontha

Larvae can be destroyed only by digging a site. Spillage of soil under bushes with solutions of insecticides, etc., will also help.

Rose bedeguar gall

Rose bedeguar gall is a multi-colored hairy growth that is formed on the leaf of the larvae of Hymenoptera insects of the walnut. He does not do much harm to roses. The leaf affected by them should be simply cut off and burned.

When a Diplolepis rosae is found, the plant can be sprayed with solutions of insecticides. Preventive spraying is carried out before the buds blossom. Removing and destroying galls before they dry and the wasps emerge may help to reduce the infestation.

The head gully is a very large brown outgrowth at the base of the stem. For a plant, it is not very dangerous. In autumn it should be carefully cut off, and place the cut grease with garden varnish. Such a gall is dangerous for a plant if it forms on the roots of a rose.

Not bad prevention from the galls will be planted next to roses marigolds or preventive watering of the whole plant infusion of them.

Thus, the fight against pests of roses implies a good knowledge of your enemy and effective methods of combating it.
