Produção de frutos e caracterização de ambientes de ocorrência de plantas nativas de araticum no cerrado de Goiás

This study had the objective to evaluate the production of araticum fruits in the Cerrado of the Goias State. Fourteen areas with high natural occurrences of araticum in the whole state were selected from January 2000 to July 2002. In each area, thirty to forty mother trees were selected. The experimental research corresponds to the hierarchical model for the fruit production, and that means that the original data was submitted to an analysis of variance. The spatial phenotypic structure variation among populations was investigated through dendrograms by the UPGMA linking criterion. The results demonstrated that the production of araticum fruits is low and changeable in areas and years, and the average corresponds to 2.97 usable fruits and 1.37 not usable fruits per plant. The phenotypic variation of morphologic characters between populations of araticum of the Goias state does not present a standard of space arrangement. The production of fruits per plant is very changeable, since some plants present productive and apparent quality characteristics of fruits that make them potential plants matrix. The main pests that attack the fruits of araticum are: Spermologus funereus, Cerconota anonella and Bephratelloides pomorum. The anthropic pressure on natural environments of production of araticum has reduced the current production and can make the future productions impracticable.

Caracterização taxonômica, novos registros de distribuição e de hospedeiros de Anastrepha turpiniae Stone (Diptera: Tephritidae), no Brasil

The aculeus tip of Anastrepha turpiniae Stone resembles those of A. fraterculus (Wied.) and A. zenildae Zucchi. Therefore, A. turpiniae can be confused with these two species. However, A. turpiniae differs from A. fraterculus and from A. zenildae by having aculeus tip more slender. Additionally, its aculeus tip is longer than in A. fraterculus and the serrate portion is shorter than in A. zenildae. Anastrepha turpiniae had been previously recorded in Brazil, in the State of Minas Gerais (unknown host). New distribution and host records, based on this paper, are: State of Amazonas (from Terminalia catappa), State of Goias (from T. catappa and Andira humilis) and State of Sao Paulo (from Eugenia dodoneifolia, Psidium guajava, Prunus persica and Syzygium jambos).
