An exploratory insect survey of tropical soda apple in Brazil and Paraguay

An exploratory survey was conducted in Brazil and Paraguay to record insects feeding on Solanum viarum Dunal (Solanaceae). A list of insects collected is included. The survey indicated that a diverse group of phytophagous insects is associated with S. viarum, and some of them may have potential as biocontrol agents of S. viarum in Florida.

A new species of megastigmus (hymenoptera: Torymidae: Megastigminae) from Brazil

In this paper a new parasitoid Megastigmus Dalman, 1820 (Hymenoptera: Chalcidoidea: Torymidae: Megastigminae) species was described in the subgenus Torymus, associated with the gall-forming Leptocybe invasa Fisher & La Salle (Hymenoptera: Eulophidae) in eucalypt plantations in Brazil.

Frugivorous flies (diptera: Tephritidae and lonchaeidae) and native parasitoids (hymenoptera) associated with pouteria caimito (sapotaceae) in Brazil

This study presents new reports on frugivorous flies and their parasitoids associated with the fruits of Pouteria caimito Radlk. (Sapotaceae), a plant native to the Amazon region. In addition to the new reports, this study also presents the infestation and parasitism rates, for dipterous and hymenopteran parasitoids, respectively.

Belvosia sp (diptera: tachinidae) parasitizing halysidota sp (lepidoptera: arctiidae) caterpillars on ficus benjamina (moraceae) in Brazil

Ficus benjamina L. (Moraceae) is an exotic ornamental plant in Brazil. The aim of this study was to identify a defoliator and its parasitoid on F. benjamina plants in Vicosa, Minas Gerais, Brazil and to determine the number of pupae and the emergence of lepidopteran and a dipteran. Four Halysidota sp. (Lepidoptera: Arctiidae) groups, with 158, 144, 137 and 129 last-instar caterpillars aggregated on the trunks of 4 F. benjamina trees. These caterpillars were collected, held in plastic containers with ficus leaves until development and emergence were completed. Adults of 1 undescribed lepidopteran species (Halysidota) and 1 dipteran species [Belvosia (Tachinidae)] emerged from the Halysidota pupae. An average of 118 viable Halysidota pupae per group were formed, and an average of 62.5 Belvosia individuals emerged from these host pupae per Halysidota group. From a grand total of 472 Halysidota pupae only one adult emerged. Halysidota sp. damaged F. benjamina plants in Vicosa, Minas Gerais, Brazil, but this defoliator was parasitized by Belvosia sp. The findings reported here indicate that Belvosia sp. appears to have the potential to reduce populations of Halysidota sp. and possibly protect F. benjamina in ornamental plantings.

Periphoba hircia (lepidoptera: saturniidae) defoliating plants of acacia mangium in the state of roraima, Brazil

Larvae of Periphoba hircia (Cramer) (Lepidoptera: Saturniidae) defoliated Acacia mangium in the state of Roraima, Brazil. This is the first report of this species defoliating A. mangium in Brazil. The damage to the foliage was substantial and P. hircia should be monitored to ascertain its significance as pest of this plant. The larval stage of this species had 6 instars. Its cocoons were woven either on A. mangium leaves or in the soil. The pupal period of P. hiricia reared on A. mangium lasted 6 months. Its adults were dimorphic with females larger and having more prominent abdomens than males.

The plants by Daniel Rolander (c. 1723-1793) in Diarium Surinamicum (1754-1765) and herbaria

The manuscripts of Diarium Surinamicum by Daniel Rolander practically remained ignored and unpublished for over 240 years, till the recent publication of its translation into English, which occurred in 2008. In this, the names of species described and/or cited by Rolander were faithfully retained, hence preserving the indication of them without authorship, for the vast majority. In the present work, all the names of plants that were treated by Rolander in his journal, about 664, including by tradition the fungi and algae, are contextualised in relation to the authorship, reference to the publication of the protologue, pagination of citations/descriptions in the manuscripts and in the published translation, indication of probable misidentifications with possible alternative names, vernacular names, and related literature. Additionally, we searched for the vouchers collected by Rolander, scattered in several herbaria, which have been linked to the probable names and descriptions in the diary. Given the considerable time till the publication of these names, and by the lack of indication of their nomenclatural types in the English version, the great majority of the new species described by Rolander, which would have priority if published in due time, became invalid names according to the ICN. Nevertheless, the list of Rolandrian species here presented, from his work that has finally taken a place in the history of natural sciences, shows that he was also a competent botanist, besides being a skilled entomologist, having recognised and detailedly described many of the Surinamese plants hitherto unknown to science.
