Resumen

Survival and insect pests of forest and fruit species in Puerto Almendra, Lore‑ to, Peru were evaluated. Seedlings and cuttings of 15 forest species and 04 fruit species were obtained from natural populations and home gardens; these were installed in plots of 25 x 25 m, 25 individuals per species. Spondias pur‑ purea cuttings had the highest survival (84%), Spondias mombin and Spondias dulcis reached 36% and 24% respectively. Plants from botanical seeds with Very good survival (80‑100%) were Copaifera paupera, Dipteryx odorata, Ca‑ rapa guianensis, Swietenia macrophylla, Hura crepitans, Chorisia integrifolia, S. mombin, Guazuma ulmifolia, Pleurothyrium parviflorum and Amburana cearen‑ sis. With Good survival (60‑79%) are Cedrelinga cateniformis, Cedrela odorata, Genipa americana. In the category Regular (40‑59%) are Caryodendron orino‑ cense y Calycophyllum spruceanum. In the category Bad (< 40%) are Calophy‑ llum brasiliense and Aniba rosaeodora. Insect damage on plants was thoroughly checked, 04 pests were recorded: Hypsipyla grandella on S. macro‑ phylla, C. odorata and G. ulmifolia with incidences between 100 and 84%; Pa‑ rasaissetia nigra had incidence (88%) on G. ulmifolia; Apioscelis bulbosa was found on G. ulmifolia, C. integrifolia, S. purpurea and S. dulcis with incidences of 80, 56, 8 and 4%, respectively and Aphis gossypii was recorded on S. purpurea with 20% incidence. This research provides information oriented to the pro‑ pagation, management and conservation of forest and fruit species in the Pe‑ ruvian Amazon.
