**3. Conclusion**

The presence of pests and diseases in the seedling stage was common. In the germination beds, Fusarium behaved recurrently in most of the germination beds, mainly in *C. odorata* and *R. regia*. The most specific pests *were Hypsiphylla grandella* for *cedrela odorata*, the fungus *Curvularia lanata* for T. rosea, as well as *Prospodium perornatum* for the same species.

Excess shade, continuous irrigation, residual moisture and evapotranspiration were key factors of importance for the development of fungi almost during the six months of monitoring of the plants in the nursery, although shade was removed from the nursery trees twice this year. it reappeared in a short time.

The pests entered the nursery in the area where the nursery adjoins herbaceous and shrubby vegetation, that is, the natural habitat of these organisms is that type of environment. It was recorded that the more the plants grow, the greater the possibility of shelter for pests.

The reason for including shrubby species such as Icaco, or herbaceous species such as lantana and Hamelia, is that in disturbed areas, herbaceous plants are the pioneers of secondary succession, and when reforestation or restoration areas are established, herbaceous species are very important for maintaining soil cover and protection. In addition, they are very important in attracting beneficial insects for Pollination.

Due to the abuse of agrochemicals for various uses, biological diversity (Flora and fauna) has been greatly reduced, so it is necessary to restore ecological conditions and habitats to generate a status of ecological balance at various scales in time. Hence, it is very important to know the pests or diseases that could affect the species used in habitat restoration.

In any environment that has been altered, pests settle in the islands of vegetation present, so their eradication is almost impossible due to their qualities of adaptation to the changing environment.

In this way, the species that are planted will have different functions over time in which the ecosystem normalizes and the insect pests adapt to that environment.
