Borecznik rudy (Neodiprion sertifer)
Borecznik ore - pest description
Symptoms of feeding on the red rhinoceros(Neodiprion sertifer) can be seen in the period from May to June, when its larvae (gray-green caterpillars) gnaw pine needles with enthusiasm, sometimes completely stripping pine branches from needles.They most often attack young pines growing on poor soils and in highly sunny places.The caterpillars of the redbug appearon the mountain pine, the norway pine, the black pine, the white pine, the white pine and other pines. A similar pest may also appear on the common pine -pine woodworm(Diprion pini), causing identical damage.
Caterpillars of the red lionare gray-green with black heads and reach 2.5 cm in length, andthe caterpillars of the pine forestare yellow-green with orange heads .Larvae of the larvae feed in groupsof several or even a dozen or so, biting the older needles and leaving the young shoots intact. Fortunately, this gives the tree a chance to regenerate. At the end of June, the larvae descend into the soil, where they spin cocoons and pupate by September. Adult insects lay eggs by placing them in rows along the edges of the needles. Next spring the larvae will hatch again in the form ofcaterpillars eating pine needles

Borecznik rudy - fighting and spraying
With a small number of trees in the garden, it is worth looking after the pines from the beginning of May, andafter the caterpillars appear, remove them manuallybefore they damage them. If we are unable to remove the caterpillars, immediately after spotting the pest, sprayon the red mushroomusing contact preparations to combat caterpillars and biting-sucking pests. Among the resources available for amateur use in gardens, Karate Zeon 050 CS, Karate Gold Tuje and Iglaki and Decis 2.5 EC will be useful. For full effectiveness, spraying should be repeated after 7-10 days.
The boron ore causes a lot of damage in forests.Fortunately, foresters have a much wider set of measures for professional use at their disposal. Here ,preparations such as: Acetamip 20 SP, Ceta 20 SP and Dimilin 480 SC are used for spraying the red mushroom.
Finally, it is worth adding that the boron larvae are not the only caterpillars on a pine tree that we can encounter. For comparison, it is worth getting acquainted with the descriptions of the feeding symptoms of the pine rotunda and the nun moth. However, the methods of combating all these pests and recommended spraying agents are quite similar.
