Abstract

This is the first record of the beetles attack (Curculionidae, Scolitinae) in neem plantations located in Brejinho de Nazaré, Tocantins, Brazil. The insects were observed on plants between 7 and 10 years old and were identified as Xylosandrus compactus (Eichhoff), Cryptocarenus diadematus Eggers, 1937 and Hypothenemus sp. Westwood, 1836. The attacked plants showed a growth rate considered low for the region, had a low seed production, high defoliation and branch sprouting, followed by the death of many young shoots and/or the tip of the branch. The insects caused intense gum exudation in the holes caused by them. This problem has similarities with the syndrome called "decline of neem", reported in Africa.
