Resumo
From 1800 ornamental trees sampled in Goiânia urban area, Paquira aquatica represented 62,7 %, Cesalpinia sp. 15,3 %, Bauhinia variegata 10 %, Sapthodea campanulata 6 %, Terminalia catappa 3,2 %, Acacia sp. 1,2%, Ponciana sp. 1,0 %, and other species 1 %. The most frequent insect species observed in P. aquatica were Psylla floccosa ( 92,3%), Steirastoma breve (76,7%), Palindia detracta (63,4%), Phelypera shuppeli (43,4%) and Euchroma gigantea (23,7%). The most severe injuries to plants are caused by S. breve, which desiccates trunk and stems, and E. gigantea. Its larvae destroy the whole root system and cause the fall of the tree. Orthezia praelonga was observed in 84,6 % of the sampled B. variegata; in 30 trees 20% died after three years and 40% at the of the fourth year; from 50 seedlings 36% were desiccated after one year and 58% 36 months later. O. praelonga was observed in 94,6% of S. campanulata; in 32 trees 8% were desiccated in one year, 18% in the second and the remaining at the end of the third year. Icerya purchasi was observed in 84,7% of Cesalpinia sp.; from 48 trees 5% were desiccated after six, 16 % two years later and 30% at the end of the fourth year; from 50 seedlings of this species, under intense attack, 78% were desiccated in 15 days. Quesadas gigas e Dorisiana sp. were observed in Acacia sp. In Ponciana sp. it was observed the presence of some species of Scolytidae, Platipodidae and Rhinotermitidae, and no injuries were observed in Terminalia catappa.
