Resumo. Os besourosolanaceae é uma das famílias de plantas de maior interesse econômico mundial devido seu uso na alimentação, indústria farmacêutica, jardinagem e medicina tradicional (Lavie 1986;Roddick 1991;Hawkes 1999;samueLs 2009;Lim 2013). Considerando somente o cultivo de batatas, tomates, berinjelas e pimentões, as solanáceas correspondem a cerca de 28 milhões de hectares cultivados no mundo e mais de 600 milhões de toneladas produzidas ao ano (Fao 2014). Com distribuição cosmopolita, Solanaceae apresenta cerca de 2700 espécies em 98 gêneros, contudo, um único gênero -Solanum, concentra cerca de 50% (1330) O jiloeiro é originário da Nigéria, África, enquanto que a berinjeleira tem origem ainda controversa, sendo comumente sugerida a Índia, além da China e África (Lim 2013). Os frutos dessas solanáceas, jiló e berinjela respectivamente, possuem sabor amargo e são bastante apreciados na culinária, além disso, possuem alto valor nutricional e propriedades medicinais (matsuBaRa et al. 2005;Lim 2013). Devido as suas exigências climáticas, o jiló e a berinjela são tipicamente cultivados nas regiões tropicais da África, Ásia e América do Sul (Lim 2013). No Brasil, essas hortaliças foram introduzidas durante a colonização portuguesa: a berinjela no século XVI pelos portugueses e o jiló no século XVII pelos africanos (madeiRa 2008).

An infestation of Tetranychus gigas (Acari: Tetranychidae) was observed on Priva lappulacea plants in anthropized areas in the municipality of Paraíso do Tocantins, Tocantins state, Brazil. Mites were found in large colonies mainly on the underside of the leaves. This observation confirms P. lappulacea as a new host of T. gigas in Brazil, in addition to confirming the first records of P. lappulacea and T. gigas for Tocantins state.Priva lappulacea (L.) Pers. (Verbenaceae): New Host of Tetranychus gigas Pritchard & Baker (Acari: Tetranychidae) in BrazilResumo. Relata-se a infestação de Tetranychus gigas (Acari: Tetranychidae) em plantas de Priva lappulacea em área antropizada no município de Paraíso do Tocantins, Estado de Tocantins. Os ácaros foram observados em numerosas colônias, principalmente na face inferior das folhas. Após confirmação, registra-se, portanto uma nova planta hospedeira para T. gigas no Brasil, além do primeiro registro de P. lappulacea e de T. gigas para o Estado de Tocantins.

Resumo. A partir de coletas realizadas em área rural no município de Paraíso do Tocantins, TO, foram obtidos exemplares do percevejo-de-renda Gargaphia lunulata (Mayr). Os insetos estavam ocasionando danos em cultivos comerciais de feijão (Phaseolus vulgaris L.) (Fabales: Fabaceae), quiabo [Abelmoschus esculentus (L.) Moench] (Malvales: Malvaceae), maracujá (Passiflora edulis Sims) (Malpighiales: Passifloraceae) e também em plantas daninhas conhecidas como flor-do-guarujá (Turnera ulmifolia L.) (Malpighiales: Turneraceae) e fedegoso [Senna alata (L.) Roxb.] (Fabales: Fabaceae). A ocorrência de G. lunulata em feijão, quiabo, flor-do-guarujá e fedegoso é registrada pela primeira vez no Estado, sendo os percevejos-de-renda encontrados com maior densidade populacional em flor-do-guarujá, maracujá e feijão.Record of host plants of Gargaphia lunulata (Mayr) (Hemiptera: Tingidae) in rural area in the state of Tocantins, BrazilAbstract. From the samples made in rural areas in the municipality of Paraíso do Tocantins, Tocantins state, Brazil, specimens of the lace bug Gargaphia lunulata (Mayr) were obtained. The insects were causing damage to commercial of bean (Fabales: Fabaceae), okra [Abelmoschus esculentus (L.) Moench] (Malvales: Malvaceae), passion fruit (Passiflora edulis Sims) (Malpighiales: Passifloraceae) (Turnera ulmifolia L.) (Malpighiales:Turneraceae) and fedegoso [Senna alata (L.) Roxb.] (Fabales: Fabaceae). The occurrence of G. lunulata in cowpea, okra, “guarujá flower” and “fedegoso” is recorded for the first time in the state, with the lace bugs found with higher population density in “guarujá” flower, passion fruit and bean.

Eucalyptus represents a species with consolidated cultivation in the Cerrado and that has been cultivated in several states that cover this Biome. Thus, the objective was to evaluate the growth and development of Eucalyptus urophylla seedlings in response to soil and foliar zinc application in a Cerrado Red Latosol. Two experiments were set up in a completely randomized design, with five treatments and seven replications. The first experiment consisted of five doses of Zn, in the form of zinc sulfate for both experiments, 0; 2.5; 5; 10 and 20 mg/dm³ applied via soil and the second experiment consisted of five doses of Zn, 0; 2.5; 5; 10 and 20 mg/L applied via foliage plus an extra dose of 20 mg/dm³ of Zn applied via soil, this dose being necessary due to the low zinc content in the soil and which could compromise the initial development of seedlings that would receive applications via leaf. The experiments were carried out in a greenhouse and after 80 days of planting, the following were evaluated: stem diameter (neck), height, root length, number of leaves, shoot and root dry matter, total dry matter, of macro and micronutrients in leaves and gas exchange: internal carbon concentration, stomatal conductance, transpiration and net photosynthesis rate. Even though Eucalyptus urophylla seedlings did not show statistically significant differences, part of the evaluated variables showed a positive response to the application of zinc, analyzing the linear and quadratic regression graphs, mainly at doses of 10 and 20 mg/L and 10 and 20 g/dm³.

Leaf-cutting ants of the genus Atta, also known as leaf-cutting ants, are considered pests in forestry, in various agricultural crops, and also in pastures, causing great damage. Mineral elements are of great importance in increasing crop production and productivity and are involved in the defense mechanism and tolerance of plants to pest and disease attacks, when properly balanced in the soil. The objective of this study was to evaluate the cutting preference of leaf-cutting ants Atta sexdens for Eucalyptus urophylla seedlings submitted to different doses of zinc (Zn) cultivated in a dystrophic Cerrado Latosol. The doses of zinc provided were 0 (control) and 20 mg/dm³ plus 20 mg/L via foliar, in the form of zinc sulfate. The seedlings used were kept in a greenhouse for up to 80 days and then submitted to laboratory evaluation. The leaves of seedlings treated with different doses of zinc were offered in Petri dishes to three colonies of ants from artificial nests of A. sexdens in the laboratory with free choice between treatments. The percentage of leaf tissue cut and transported to the nests was evaluated for 20 minutes between different doses and colonies, and four sequential offers of leaves were made. Through the data obtained, it was observed that there was no preference for cutting the leaves of eucalyptus seedlings treated with different doses of zinc by the colonies of leaf-cutting ants Atta sexdens.
