Abstract: O uso de mudas do tipo peda o de rizoma, vem, a cada dia, sendo procurado intensivamente como material de propaga o de bananeiras. Porém, ao se trabalhar com esse tipo de mudas há necessidades de se conhecer o efeito do peso do rizoma em rela o ao seu enraizamento inicial, pois quanto maior o peso das raízes, melhores ser o as mudas. De acordo com a análise estatística concluiu-se que há um maior enraizamento em peda os de rizomas de maior peso. Pieces of rootstalk are being used more and more intensively as a means of reproducing banana plants. However, in order to work effectively with this means of reproduction, it is necessary to know the effect of the rootstalk’s weight when it is first planted, because the greater the weight of the rootstalk, the better the shoots will be. On the basis of statistical analysis, it was concluded that the heavier pieces of rootstalk root better.

Abstract: O pequizeiro (Caryocar brasiliense Camb.) é uma espécie de grande potencial econ mico do cerrado. O objetivo deste trabalho foi caracterizar vinte áreas de cerrado com alta densidade natural de pequizeiros na regi o Sudeste de Goiás, sendo cada área de 1,0 ha. Chegou-se às seguintes conclus es: o pequizeiro ocorre em solos considerados de fertilidade baixa para a maioria das plantas cultivadas; os cambissolos e o litossolo apresentam maior densidade de plantas de pequizeiro quando comparados com os latossolos; a densidade de plantas de pequizeiro correlaciona-se positivamente, entre as áreas, com os teores de P e Zn e com a CTC total do solo; a área basal média dos pequizeiros correlaciona-se positivamente com o teor de K e a satura o por bases, e negativamente com os teores de H+Al e a CTC total; a altura média e a produ o dos pequizeiros correlacionam-se positivamente com o teor de K no solo e com a satura o por bases; a produ o de frutos por planta, em média, é baixa e proporcional à altura e ao diametro médio da copa; o número de plantas com frutos foi maior que o de plantas sem frutos a partir do diametro de 10 cm, sendo esta uma rela o que aumenta com o diametro. PALAVRAS-CHAVE: Frutíferas do cerrado; pequi; Caryocaraceae; fertilidade do solo. "Pequizeiro" (Caryocar brasiliense Camb.) is a species with great economic potential in the Brazilian savannah (cerrado). The objective of this study was to characterize 20 cerrado areas with natural high density of pequizeiros in the southeast of Goiás, which area comprise 1 ha. The study showed that the "pequizeiro" is present in soils which would be considered of low fertility for most cultivated crops. A larger amount of this species is present in Inceptisol and Entisol than in Oxisol. Tree density is positively correlated with P and Zn soil content and total CTC. Average basal tree area is positively correlated to K and base saturation, and negatively correlated to H+Al and total CTC. Average height and yield are positively correlated to soil potassium content and base saturation. Fruit yield per plant is low and is directly related to tree height and canopy diameter. The number of trees with fruit is larger than that of trees without fruit in those trees with a diameter larger than 10 cm. This ratio increased as the diameter increased. KEY WORDS: Cerrado fruit tree, pequi, Caryocaraceae, soil fertility.

Abstract: A grande procura atual de mudas de bananeiras do cultivar Nanic o (Musa acuminata AAA) em Goiás, principalmente na regi o do Mato Grosso Goiano, tem for ado o transporte de mudas a grandes distancias. A maioria destas mudas s o transportadas sob a forma de peda os de rizoma com aproximadamente 1 Kg. Tem-se observado uma falha acima do previsto quando se utiliza este tipo de muda. O presente trabalho foi realizado para determinar o efeito do período de armazenamento sobre a brota o deste cultivar. Com base nos resultados concluiu-se que no período de armazenamento estudado (45 dias) praticamente n o houve diferen a na brota o das mudas. Somente aquelas armazenadas por 5 (cinco) semanas apresentaram inexplicavelmente um índice baixo de pegamento. Because of the tremendous current demand for Nanic o (Musa acuminata AAA) banana shoots in the state of Goiás, notably in the “Mato Grosso Goiano” area, shoots have had to be imported from far away. The greater part of these shoots are transported in rootstalk form. Each rootstalk weighs approximately 1 Kg. A larger portion of these shoots than been anticipated, are defective. The present study was made to determine the effect of storage time on the budding of this particular banana rootstalk. The results of the experiment show that during the period of storage, forty-two (42) days, that was studied, there was almost no difference in budding among the rootstalks. Only those which were stored for five (5) weeks showed, unexplainably, a low budding index.
ESTUDO COMPARATIVO DE INSETICIDAS CLORADOS E FOSFORADOS NA ATRATIVIDADE DE ISCAS PELO “MOLEQUE DA BANANEIRA” (Cosmopolites sordidus Germar, 1824) COMPARATIVE STUDY OF CHLORATED AND PHOSPHORATED INSECTICIDES IN BAIT ATTRACTIVENESS BY “BANANA BORER” (Cosmopolites sordidus GERMAR, 1824)

Abstract: A broca-da-bananeira ou “moleque” (Cosmopolites sordidus Germar) é urna das pragas mais importantes da bananeira. A revis o de literatura mostra que os produtos clorados s o os mais utilizados e recomendados no combate a essa praga, principalmente, Aldrin. O presente trabalho visou a testar inseticidas fosforados e também verificar o tipo de isca mais atrativa. A análise estatística dos dados obtidos demonstrou haver diferen a significativa entre os tratamentos, entre os dois tipos de iscas, e na intera o iscas x tratamento. Com base nos resultados e observa es feitas durante a fase experimental, podemos tirar as seguintes conclus es: a) As iscas do tipo sanduíche, feitas com peda os de rizoma s o mais atrativas do que as do tipo telha, feita de peda os de pseudo-caule, cortados longitudinalmente; b) O inseticida que apresentou melhores resultados foi o RHODIATOX (Parathion). The efficiency of several insecticides for the control of the banana borer were tested in two kinds of traps. The cloride insecticides are most widely used but they are probably repellent to the weevil. DDT, Aldrin, Diazinon and Parathion were compared in two kinds of traps: slices of rhizome and pieces of pseudostem. The best results were obtained with Parathion in rhizome slices.

Abstract: O bacupari, Salacia crassifolia (Mart.) Peyr, (Hippocrateaceae) é uma frutífera nativa da regi o dos cerrados, utilizada pela fauna e também pela popula o da regi o, embora seus frutos sejam muito atacados pelas moscas-das-frutas, e por isso seu consumo fica limitado. De polpa branca à alaranjada, de sabor levemente ácido e muito agradável os frutos dessa espécie podem ser consumidos ao natural ou na forma de sucos. Neste trabalho apresenta-se um levantamento da entomofauna associada aos frutos do bacupari, coletados em 11 municípios da regi o dos cerrados no Estado de Goiás, no período de setembro de 1995 a dezembro de 1999. No Laboratório de Entomologia da Escola de Agronomia da Universidade Federal de Goiás, esses frutos foram, inicialmente, contados e pesados e, posteriormente, acondicionados em caixas de polipropileno com areia úmida para obten o de pupários e insetos adultos. Tephritidae foi a família mais freqüente nos frutos do bacupari, com 54,22% dos insetos coletados. Nessa família foram registradas as espécies Anastrepha sp. (espécie nova em fase de descri o), A. zenildae, A. obliqua, A. fraterculus, A. sororcula e A. serpentina. Na família Lonchaeidae foi coletada Neosilba sp., em Muscidae, Atherigona orientalis e espécimes da família Oititidae. Dessas moscas foram obtidos os parasitóides Doryctobracon sp. (espécie nova), D. areolatus, Dicerataspis flavipes, Lopheucoila anastrephae, Aganaspis nordlanderi e A. pelleranoi. Foram coletados isoladamente no mesmo fruto exemplares de Anastrepha sp. e Lonchaeidae e Anastrepha sp. e A. zenildae comprovando a sobreposi o dessas espécies por fruto. PALAVRAS-CHAVE: Insecta; frutífera nativa; levantamento populacional. The bacupari (Salacia crassifolia ) is a native fruit plant of the Brazilian cerrado areas. Although a high fruit fly infestation limits its utilization, it is eaten by animals and humans. Fruits present orange colored pulp, with slightly acid flavour and can be apreciated in natura or juices. The objective of this study was to assay bacupari plant features in Goiás State cerrado and to verify insects associated to bacupari, to determine infestation index and to verify this plant as a natural reservoir of fruit flies for adjacent orchards. Samples were collected during the frutification stage from September to December from 1995 to 1999 on 11 counties in Goiás State. The insects found more often were from Tephritidae (54.22%) as Anastrepha sp. (new species), A. zenildae, A. obliqua, A. fraterculus, A. sororcula, A. serpentina. Insects from other families were also identified: Lonchaei

Abstract: A produ o de mudas de espécies frutíferas nativas é de grande interesse para o Estado de Goiás, principalmente visando à recomposi o dos cerrados e à produ o comercial dessas espécies. Com o objetivo de proporcionar melhor emergência e crescimento das plantas de cagaita (Eugenia dysenterica DC) foram testadas três capacidades volumétricas de substratos em tubetes (50 cm3, 120 cm3 e 228 cm3) e três tipos de substratos: solo + terri o de mata + vermiculita (1:1:2 em volume); solo + terri o de mata + vermiculita (1:1:2 em volume) + adubo químico (Termofosfato Yoorin – 1g/L de substrato) e composto organico industrial – Plantmax. O delineamento experimental adotado foi em blocos completos casualizados com parcelas subdivididas, utilizando-se oito repeti es e 16 tubetes por subparcela. A composi o solo + terri o de mata + vermiculita mostrou ser um substrato adequado para o crescimento das plantas de cagaita, e esta espécie apresentou boa resposta à adi o de adubo químico. Para a produ o de massa de matéria fresca e seca da parte aérea e do sistema radicular, este substrato superou os demais, embora as plantas, aos 160 dias, n o tenham apresentado diametro do caule ideal para a realiza o da enxertia. Os tubetes com maiores capacidades volumétricas propiciaram maior crescimento às plantas. PALAVRAS-CHAVE: Frutífera do cerrado; Myrtaceae; propaga o. The production of transplants of native fruit trees is of great interest for the state of Goiás aiming at the commercial production of these species and the recomposition of the Cerrado (tropical savannas) vegetation. With special interest on high emergence rate and fast growth of Cagaita (Eugenia dysenterica DC) transplants, there were tested three volumes of substract in tube-like plastic containers with 50 cm3, 120 cm3 and 228 cm3, and three types of rooting media such as soil + forest humus + vermiculite (1:1:2), the same with 1 gram of Yoorin (thermophosphate) per liter, and industrial organic compound Plantmax. The experiment was arranged in randomized complete block design with eight replications and split plots with 16 containers each. The rooting medium soil + forest humus + vermiculite showed to be favorable for fresh and dry matter production of over ground parts and underground parts of the plants. A good response was also obtained with the fertilizer treatment. The best growth of plants was observed in the bigger containers. Nevertheless, 160 days after seeding the transplants had not reached the stem diameter sufficient for grafting. KEY-WORDS: Cerrado fruit tree; Myrtaceae; propagation.
