Native and imported pine guestsThere are a lot of animals that feel comfortable in the pines, and unfortunately new pests are being increasingly carried off their natural habitat to new regions. Such imports are even increasing worldwide as a result of the globalization of trade, which can lead to economic and ecological damage in the case of forest trees. So it is not wrong if you are interested in the small animals on your jaw.
To the pine visitors belong for example different longhorn beetles, of which especially the Pogonocherus fasciculatus, the pine twig, andof the Cortodera femorata, the pinetop deep-eye buck, for which pine is "responsible".
In addition, there are various bark beetles that have multiplied massively since the 1990s. The fact that these beetles can become a serious threat, especially in the Canadian province of British Columbia, where it is expected that by 2013, 80 percent of local pine trees by a bark beetle called Mountain Pine Beetle to be destroyed.
In addition, some butterflies like to populate pines, like the pine beauty, of the bordered white and the pine moth, Among the wasps species are the Pine sawfly and the Kiefer cultural pamphiliidae especially interested in the pines. Other pine visitors are the Jewel beetle and different Pine weevil.
Dangerous pine pestsWhile the butterflies, wasps and beetles also contain beneficial insects and even some specially protected species, the nuns, who are also more inclined to the pine trees (Lyrnantria monacha L.) no more to the microorganisms, which could be neglected as harmless.
The nun tends to proliferate massively and likes to grow strong, especially as a result of warm, dry summers. It eats especially spruces completely bald, which are often irreversibly damaged already by this Entnadelung. Pines can usually recover from a single nun infestation. Repeatedly heavy feeding is then deadly for them. For this reason, the forest authorities often combat nuns, even if a critical number of eggs has only been determined in parts of a stock. For this purpose, various pesticides are used, which are not available for private use; More environmentally friendly (biological or biotechnical) control methods are currently not apparent. In May 2012, z. For example, in Altmarkkreis Salzwedel (Saxony-Anhalt on the border with Lower Saxony) about 4,400 hectares of forest air are sprayed with pesticides to prevent the spread of nuns.
Even more dangerous is the pine wood, which currently does not seem to have reached us. Various plant protection services and forest administrations are also strengthening the monitoring of imported timber storage facilities from which the nematodes could be transferred to endemic stocks by longhorn beetles. If this dangerous pest of pines one day finds its way to us, he would, for. For example, Brandenburg may find favorable conditions where around 80 percent of the forests are made of pine trees.
Even so, the fast-track to lethal injection is the last thing you can do when sizing small animals on your pines. Because initially z. For example, if you have not said at all whether it is pests, perhaps beneficial organisms protected by the Federal Law on the Protection of the World have also found favor with your jaw. So there are a lot of other things to do before that:

So you can quickly find out if there is an alert in your area about imported or native pests. If this is not the case, first of all a detailed analysis of the condition of the trees and the recent changes has to be made: you should check the soil around your trees, the moisture supply and the nutrient supply, and also ask if weeds have been used in the environment under which your trees suffer. Most pests prefer to attack weakened and damaged trees.
Own control of pine pests: Better only with expert adviceIf everything is alright in the environment, it is still advisable to first get expert support, if you want to tackle the infestation of a pine tree. This has several good reasons:
In many cases, you do not need to do anything at all.If your jaw z. If, for example, you are visited by sawfly wasps in the spring, a healthy tree should be able to cope with it without you intervening.
Before spraying pesticides you first have to make sure that you are allowed to use them. Against the larvae of Gespindblatt waspe is z. As an agent with the active ingredients pyrethrum and rapeseed oil (Spruzit) allowed, but not for pines in the house and allotment area. In addition, you would have to hit each caterpillar directly when spraying - there is probably going to be faster collecting anyway.
Because among the visitors of your pine, there could be several species that are protected by the Federal Law on the Protection of the Bark:Coleoptera) are z. For example, with few exceptions, the weevils (buprestidae), the longhorn beetle (cerambycidae), the oil beetles (genus meloe), the Schröter (Lucanidae) and the ground beetles under special legal protection.
Therefore, before the use of any pesticides always the exact diagnosis, but in addition to the exact determination of the pest may bring as pleasing results as a complete all-clear: So a yellowing of the needles in the inner or lower part of the branches in pine trees is quite normal "So, you could not only get advice on how to fight it if you consult a specialist, but you could also learn that he is simply fine for your jaw.
