Insects attack a beautiful plant, and soon it dies.
The firefighter beetle belongs to the leaf beetle family and carries a greater threat to the leaves of the flower. Today there are often two types of pests: an onion rattle and a lily rattle. Insects very much eat the foliage, sometimes you can find a plant with a bare stem.
Important! If you ignore the invasion of "firefighters", their larvae are able to eat the plant completely in 4 weeks! As soon as the pests were discovered, it is necessary to begin an active struggle with them.
- Onion cracker. This pest is a representative of leaf beetles, having a bright red body and head. Thanks to the powerful jaws, the pest can eat not only the leaves - its prey becomes the buds, flowers and stem of the plant. The main purpose of leaf beetles are lilies of the valley and lilies. That is why they have another name: "lily beetle".
- Lilium ratchet. Another pest of lilies, the so-called red bugs. They have a rather attractive appearance, they have hard wings. In the people of these pests are called "firefighters" because of their colors. They have an oblong red body and a black head.
Harm in the garden
The leaf beetles moved to the dacha plots relatively recently: back in the 90s, they lived exclusively in the forests. Today, the lily beetle is found in the garden quite often, and you need to know how to fight it.
Did you know? The larvae envelop themselves with mucus from their own excrement. Thus, they protect themselves from birds, ignoring young individuals, which they take for their stool. Undoubtedly, adults are capable of causing damage to plants in the spring, but it is not so large and cannot cause the death of a flower. It is necessary to beware of the larvae: they appear on the lower part of the leaves a little later, have an orange color. During one season, one leaf beetle lays about 450 eggs, from which several generations can hatch.
About a week after the eggs have been laid, pink larvae appear. They are located under the sheet, so they are quite difficult to notice right away. The larvae are very voracious and can eat all the leaves on the flower, leaving only the stem. After 2-3 weeks, they move to the ground, where their transformation into orange pupae begins. After 3 weeks, the red pests go hunting. For the winter, they hide in the ground or fallen leaves.
Important! When planting lilies, it is worth laying a garden film between the rows - this will prevent the beetles from digging into the ground, and you can quickly destroy them. The leaf beetles very quickly attack the plants, and sometimes you can not have time to enjoy the beauty of the flowers.
How to deal with the "leaf eaters"
If the red beetle began to appear on the lilies, you need to know how to get rid of it. There are several methods of pest control. Consider them.
The easiest and safest way to kill beetles is mechanical. They can be collected by hand or shaken into a container. The can must be closed with a lid, since the beetles are well kept on the surface of the water and, gathering in one heap, can easily get out of the tank.
If you have a small area, this method will help to cope with the invasion of "firefighters". Collect beetles need several times per season. Despite the fact that insects do not irritate the skin and do not have poison, such an event should be carried out in gloves.
If the mechanical method of fighting with beetles did not bring results, it is necessary to use more severe methods. We are talking about chemical preparations that adversely affect insects. However, they are used only when lilies do not bloom.
Did you know? Fire beetles are very tricky: when a person approaches them, they fall to the ground with a black belly up and become invisible. After the danger has passed, they take off and again are accepted for eating flowers.
The drug aimed at the destruction of this type of pest, no. It is advisable to use solutions and tools, the purpose of which is to destroy leaf-eating pests. Often to fight the "firefighters" use the same drugs as for the destruction of the Colorado potato beetle.
Over time, the ratchets become resistant to chemicals. If red bugs began to appear on the lilies, you need to know how to treat the plant. The following drugs will have the best effect: "Inta-Vira", "Talstar", "Detsis". For effective pest control, the following drugs are used: Nemabakt, Medvetoks, Aktofit, Kinmiks, Brunka, Calypso, Anteater, Abiga-Peak, Iskra Golda and Bitoxibacillin.
If the flower garden has large sizes, and you also found a lot of larvae, it is recommended to spray a special solution prepared according to the instructions. Do not deviate from the recommended proportions, as this can lead to plant burns, while the beetles will remain intact.
One of the effective ways to combat red bugs is the use of parasitoids. These insects settle on rattle bodies and gradually destroy them.
To date, 6 parasitoids have been derived. This number includes 5 wasps and one fly. Thanks to them, reproduction of pests is restrained and damage caused to flowers is reduced. According to the results of the research, thanks to the wasps, 100% of the larvae of beetles, swiftly eating lily leaves, are destroyed.
If you want beautiful and healthy lilies to always grow in the garden, you need to prepare in advance for their protection. In specialized stores it is necessary to purchase the necessary chemicals, sprayers, and always be ready to join the fight with firefighters.
Beetle Pussy or lily beetle
Sometimes on green leaves of lilies it is possible to notice red bugs.
They have a very pretty look. Red torso, black belly and legs. If you take them in hand and hold them in a fist, then you can hear a quiet rumbling. It seems as if the beetle is asking for freedom and trying to explain that he didn’t think of doing anything wrong with your flowers. Do not believe him. The beetle itself can, and will not cause much damage to flowers, but its larvae can spoil the flowers fairly. The larvae are similar to the larvae of the Colorado potato beetle. They are just as nasty and just as voracious as they are.
If they are not removed in time, they can completely gnaw the entire above-ground part of the flower.
So, if beetles are noticed on lilies - handsome, they should be eliminated immediately. You can do it manually, and you can sprinkle the plants with one of their preparations that are used to process potatoes from the Colorado potato beetle. In the case when the moment is missed, and the lilies are already devoured by the voracious larvae, manual assembly will be completely ineffective. Only chemical products will help here. Plants will look ugly, but they can be saved for future seasons. And, of course, next time not to admire the beautiful red bugs, but to destroy them in a timely manner.
Rodents - the main danger to the bulbs
If beetles and larvae can be seen on plants and quickly carry out operations to neutralize them, then it is very difficult to notice the pests that attack the bulbs. It so happens that only a memory remains of the plant. Mice or some other rodents in winter completely eat the bulb. And where the sprout should appear, there is an empty space. It is good if several scales remain from the large bulb - after some time the plant can recover. But often the mouse does not leave anything. After all, winter is so long, and the onion in lily is so tasty.
I have several times a mouse ate the most valuable bulbs. After that, I began to look for a means of protecting the bulbs from rodents.
Once I came across a wonderful book on the floriculture of the Czech edition. This book has shown how to protect the bulb. She seemed to be wrapped in a metal grid with small cells. I did not use the grid - I just could not find it. But I still found a way out. I started planting the most valuable and expensive bulbs in plastic five-liter bottles.
Container method of growing lilies
Of course, this method is rather laborious, but the most reliable. The plastic balloon will not let the mouse or the other rodents to the bulb.
I do it like this.
From a plastic bottle with a capacity of 5 or 6 liters, I cut off the conical part, in the resulting “glass” I make holes in the bottom.
Why such containers? But why. Lilies grow in one place for 3-4 years, or even more. During this time, a single nest is produced from one bulb. In containers of smaller in size, the lilies will be cramped, and they will have to be replanted more often so that they do not suffer and develop normally. And for this, time is not always there, and it is troublesome. Well, with larger tanks it’s just hard work.
There may be another question. Why not cut the bottom of the bottle? Then the holes will not have to be done. Just unscrew the cork - that's all. I tried to do so, and I did not like it. The bottle tumbles, the contents spill out of it. In general, work is very inconvenient. Therefore, I stopped on such containers.
At the bottom of the bottle must be laid drainage. This may be gravel, for example. Then I fall asleep a layer of fertile soil and make a small mound of sand. I put a lily on this mound and sprinkle it with sand, and only then fall asleep the fertile garden soil.
At the same time it is necessary that the bulb is at the optimum depth for it (three onions of diameter). When filling the soil, it is necessary to carefully monitor that the larvae of the May beetle do not fall into the tank.
Now you can bury the capacity.
It must be buried in such a way that the edges are at ground level. Neither should the container be buried or inadequately immersed.
In the first case, a hole can form where water will collect, and lilies do not like soaking, and in the second case, the bulb can freeze in winter or suffer from heat in summer.
Here is such a laborious, but very effective way to protect lily bulbs from rodents.
