(Bursaphelenchus xylophilus): It is a plague caused by a nematode, 1mm long) that develops inside the wood of pine trees and other coniferous species. Attracted by wounds in trees (pruning, felling), the vector insect Monochamus galloprovincialis oviposits, feeding on the larva of the woody tissue of the tree. It is at this stage that the larva can be infected by the nematode present. When mature, the insect infected with the nematode will be able to move to other trees, on which it will feed and to which it will be able to transmit the nematode. Beginning its attack in the resin canals, its seriousness lies in the fact that the pines die inevitably a few months after the inoculation of the nematode.

With several very similar species (Bemisia tabaci, Trialeurodes vaporariorum) the aleuródidos are small insects (1mm) that suck a large amount of sap from the leaves of multiple species of ornamental and agricultural plants. From the underside of the leaves, hundreds of eggs per female hatch in moderate temperature conditions, to later feed as nymphs (N1-N4), secreting honeydew, which causes the formation of bold, reducing transpiration and photosynthesis. They grow to adults, with great capacity for flight, which, together with their multiple annual generations (one every 15-25 days), makes them spread very quickly, making their control very complex. In addition, they inject enzymes into the leaf that paralyze the physiological processes of the plant, stopping the development and normal growth of the plant. They are potential vectors of other diseases.

With a size of 3-4mm, it is polyphagous, although it mainly attacks the genus Platanus. They hibernate as adults, to begin to suck sap and oviposit with the first spring buds, on the underside of the leaves. When feeding, the nymphs secrete honeydew, which favors the sooty mold. They pass into adulthood, thus completing the life cycle, which is repeated 3-5 times per season. The leaves become dispigmented, taking on a leaden gray coloration, ending up drying up and falling prematurely, and causing a lack of vigor in the plant.
