“…Artificial defoliation was performed by Nickele et al . (2012) in an area of newly planted P. taeda (planting in August 2007) in São Mateus do Sul (25°58′S, 50°23′W), state of Paraná, Brazil.…”

“…Ant attacks on pine plants are more frequent in the first months after planting, particularly during the first 30 days. The percentage of attacked plants diminishes in the following months, while the level of defoliation in attacked plants drops below 50% (Nickele et al ., 2012).…”

“…To facilitate comparisons, damage of leaf‐cutting ants in recently planted Pinus taeda plants can be categorized into four intensity levels: level 1: 1–50%; level 2: 51–75%; level 3: 76–100% without severing the apical meristem; and level 4: 100%, including the cut of the apical meristem (Reis Filho et al ., 2007). Until now, losses for each defoliation level have only been evaluated in young plants up to 3 years of age (Nickele et al ., 2012). However, assessments comprising longer time periods are necessary to allow for the calculation of losses in the final wood volume.…”

Acromyrmex species primarily attack Pinus taeda plantations during the first months after planting, with more intense damage in the first 30 days. 2 We evaluated potential damage by Acromyrmex crassispinus and Acromyrmex subterraneus in 30-day-old P. taeda plantations in southern Brazil by assessing the number of attacked plants and the distance reached by each colony, along with the losses in plant development resulting from different levels of defoliation. 3 Both species were significant pests in newly established pine plantations. A single colony can attack a substantial number of seedlings (up to 453 seedlings). Colonies with larger nests attacked more plants and ranged farther; A. crassispinus reached 59 m and A. subterraneus 87 m. 4 After 10 years, no significant losses in plant development were seen in seedlings defoliated less than 50% at 30 days after planting. But when defoliation of the young plants attained 75%, 100%, and 100%, including the cut of the apical meristem, volume losses reached 32%, 37%, and 43%, respectively. 5 Leaf-cutting ant controls should be carried out in plantations of P. taeda within 30 days of planting to avoid attacks. When seedlings are defoliated more than 75%, they should be replanted to avoid future losses in final wood volume.

“…So, ants preferred foraging in plants derived from natural regeneration and they did not attack the plants of commercial interest, which is exotic. Nickele et al (2012b) found that higher percentages of Acromyrmex attack in P. taeda plants occurs in the first months after planting, with larger impact in the first 30 days, in reform areas where earlier planting suffered pruning and thinning. In this case, A. crassispinus nests have been observed since the beginning of planting and the first months after planting, ants had no options of native plant resources for foraging due to soil preparation for planting (Nickele et al, 2009).…”

This work aimed to study the population dynamics of Acromyrmex crassispinus (Forel) in Pinus taeda L. plantations, evaluating the density and spatial distribution of nests over time, inferring about the period of the first nuptial flight of A. crassispinus colonies, and evaluating the levels of attack of this leaf-cutting ant on P. taeda plants. Assessments were performed monthly in the first year after planting, every three months until the third year and every six months until the plantation was six years old. The presence of nests was observed only after 15 months after planting. The nest density gradually increased until the planting completed 30 months, and decreased when the forest canopy began to close (after 54 months). Spatial distribution of A. crassispinus nests was random. Probably, the first nuptial flight of an A. crassispinus colony occurs after the third year of the colony foundation. Pinus taeda plants were not attacked by A. crassispinus throughout the evaluation period. Then, when dealing with a replanting area of Pinus plantation, where the previous forest has not been subject to pruning nor thinning, the problem with A. crassispinus is almost null if the clearcutting and the new planting occur during the winter. In this case, leaf-cutting ants control can be alleviated and it is not necessary to carry out systematic control of ants where A. crassispinus is the predominant leaf cutting ant species. Acromyrmex crassispinus control should be done only if nests are located or if attacked plants by ants are detected.

“…Segundo Buratto et al (2012), com a utilização de iscas formicidas os danos totais médios ocasionados por formigas cortadeiras em mudas de P. taeda no município de Anita Garibaldi, SC, foi no máximo de 5,38% no 63º dia de avaliação. Importante ressaltar que a forma de controle testada, diferentemente do controle com iscas formicidas, não elimina a colônia, permitindo que elas permaneçam ativas, uma vez que, de acordo com Nickele et al (2012), a espécie Acromyrmex crassispinus causa perdas em indivíduos de P. taeda somente nos primeiros meses de idade do plantio, com maior concentração nos primeiros 30 dias em áreas do planalto norte do estado de Santa Catarina. Não foram previamente contados os formigueiros presentes na área, mas o experimento só foi instalado após a confirmação de que havia formiga cortadeira no entorno.…”

ResumoEste trabalho teve o objetivo de avaliar a utilização do ingrediente ativo imidacloprid, aplicado em diferentes dosagens, por meio de gel condicionador de solo, em mudas de Pinus taeda L. (Pinaceae) recém-plantadas. O experimento foi instalado em uma das áreas da Empresa Celulose Irani S.A., no município de Vargem Bonita, SC, com desenho experimental em blocos ao acaso com 5 tratamentos e 8 repetições. As avaliações foram realizadas aos 25, 56 e 81 dias após a instalação do experimento. A análise estatística mostrou não haver diferença significativa entre os tratamentos. A presença da APP próxima ao experimento influenciou significativamente nos resultados. A intensidade de dano após três avaliações (81 dias) foi de 4,06%, resultado este promissor para o controle de quenquéns (Acromyrmex spp.) com a metodologia proposta. Palavras-chave: Controle químico; formigas cortadeiras; avaliação de dano. Abstract Evaluation of imidacloprid usage in control of Acromyrmex spp. in Pinus taeda planting.This research aimed to evaluate usage of active ingredient imidacloprid in different dosages, applied as gel soil conditioner in seedlings of Pinus taeda L. (Pinaceae) newly planted. The experiment was installed in one area of the company Celulose Irani S. A., at Vargem Bonita city, Santa Catarina State. The experimental design was randomized blocks with five treatments and 8 replicates. Evaluations were performed at 25, 56 and 81 days after the experiment beginning. The presence of Permanent Preservation Areas (APP) near the experimental area significantly influenced the outcome. The intensity of damage after three assessments (81 days) was 4.06%, a promising result for control leafcutting ants (Acromyrmex spp.) with the proposed methodology. Keywords: Chemical control; leaf-cutting ants; damage assessment. INTRODUÇÃOCaracterísticas como rápido crescimento e boa adaptação às condições edafoclimáticas fizeram das espécies Eucalyptus spp. e Pinus spp. as mais utilizadas em programas de reflorestamento no Brasil. Essas espécies, inicialmente, foram pouco atacadas por insetos-pragas quando introduzidas, principalmente por esses insetos ainda não estarem adaptados às mesmas (RIBEIRO;MENDONÇA, 2004). Entre os insetos considerados pragas em silvicultura, as formigas cortadeiras são apontadas como as mais importantes nos reflorestamentos de eucalipto e pínus, em razão dos prejuízos que causam e de sua vasta ocorrência (ANTUNES; DELLA LUCIA, 1999). No caso das mudas de Pinus taeda L., o
