“…Furthermore, no pupa was detected in mines on the adaxial surface. (Kessler & Baldwin 2002;Queiroz 2002;Leite et al 2011). Such patterns have been associated to a number of variables, such as predation risk, nutrient availability (Kessler & Baldwin 2002) and seasonality (Anstey et al 2002).…”

“…The Brazilian Savanna has been deforested for grain and cattle production (AGUIAR; CAMARGO, 2004), besides reforestation with eucalyptus (ZANUNCIO et al, 2002). However, the C. brasiliense tree is protected by federal laws and is left in deforested areas of the Brazilian Savanna (LEITE et al, 2006).…”

“…These fruits also represent the main source of income for many communities. However, uncontrolled harvesting has a strong effect on the propagation of communication from collectors of C. brasiliense fruits) and the chance that they will be attacked by insects (LOPES et al, 2003;LEITE et al, , 2009LEITE et al, , 2011a.…”

The mortality of Caryocar brasiliense in northern Minas Gerais State, Brazil

et al. 2012

ABSTRACT. The purpose of this work was to study the percentage of healthy trees, living trees and healthy branches and the renewal (natural propagation) of Caryocar brasiliense associated with the properties of soil, the floristic diversity and the canopy size of this plant. Lower proportions of live C. brasiliense trees and of healthy branches were found in the Savanna of Ibiracatu, where only 30% of the trees were healthy and without visible signs of attack by wood borers and by Phomopsis sp. We observed that C. brasiliense trees in areas where the soils contained higher levels of summed chemical bases and total sand (fine + gross) were less healthy. Moreover, the areas whose soils contained higher levels of aluminum and clay had a higher percentage of healthy C. brasiliense trees and branches. Smaller percentages of live and healthy trees and healthy branches were noted in areas with higher floristic diversity. Overall, the higher mortality of C. brasiliense trees may be associated with a higher pH and a lower content of aluminum, silt and clay, with competition with other tree species for nutrients, water and light, with the attack of Cossidae and particularly with the attack of fungi, Phomopsis sp.

Galhas são estruturas que exibem associações específicas entre o indutor e a planta hospedeira, onde são evidenciadas modificações morfológicas, anatômicas e químicas dos tecidos vegetais. Objetivou-se descrever a morfologia e a distribuição de galhas foliares de Anacardium occidentale L. (Anacardiaceae). Foram coletadas 294 folhas, da porção apical dos ramos, de indivíduos localizados na Universidade Federal do Tocantins -Campus Araguaína, TO. Foram realizadas análises morfológicas utilizando microscópio estereoscópico, paquímetro e bibliografia específica. Determinou-se o número de galhas no limbo foliar seguida da análise de regressão linear entre o número de galhas por limbo e o seu comprimento. Foram observadas galhas do tipo cônico atravessando a lâmina foliar, glabras, de coloração verde quando jovens e vermelho alaranjadas quando maduras, com distribuição isolada/agrupada e aderência total; internamente apresentou um lóculo e uma larva do indutor (Cecidomyiidae). A distribuição das galhas no limbo apresentou diferenças significativas (p<0,001), em ordem decrescente foi observado maior número de galhas entre as nervuras (57,1%), sobre a nervura secundária (35,7%), na margem (6,3%) e na nervura central (1,2%); a análise de regressão linear apresentou fracamente positiva (r 2 = 0,03; coeficiente de Pearson= 0,2025), o que sugere que a oviposição está associada, em parte, com o tamanho do limbo e que outras variáveis podem ser determinantes. Estes são os primeiros registros de galhas em A. occidentale no estado do Tocantins. ABSTRACT-Galls are structures that show specific associations between the inductor and the host plant, which morphological, anatomical and chemical changes of the plant tissues are highlighted. This paper aimed to describe the morphology and distribution of leaf galls in Anacardium occidentale L. (Anacardiaceae). 294 leafs were collected from the branches apical portion of individuals located in the Federal University of Tocantins -Araguaína Campus, TO. Morphological analyzes were performed using stereoscopic microscope, caliper and specific bibliography. It was determined the number of galls on the foliar limb followed by the number of galls per limb and its length linear regression analysis. Conical type galls were observed crossing the leaf blade, green-colored glabrous when young and orange-red when mature, with isolated/grouped distribution and full adherence; internally it presented a lobe and inducer's larvae (Cecidomyiidae). The distribution of galls in the limb showed significant differences (p <0.001), in descending order there was a higher number of galls between the veins (57.1%) on the secondary vein (35.7%) on the edge (6.3%) and the central vein (1.2%); Linear regression analysis showed weakly positive (r 2 = 0.03; Pearson's correlation coefficient = 0.2025), suggesting that oviposition is associated in part with the foliar limb size and that other variables can be decisive. These are the first records of galls in A. occidentale in the State of Tocantins.
