1. CHARACTERIZATION OF INJURY CAUSED BY Coptotermes testaceus IN Tectona grandis PLANTATIONS IN BRAZIL
ABSTRACT Coptotermes testaceus (Linnaeus, 1758) is the most important species of heartwood termite of adult trees in forests planted in Brazil. This study aimed to characterize the injuries promoted by the heartwood termite C. testaceus in Tectona grandis commercial stands. Tree bark with extend carton material on the outside, forming external galleries and

2. Constrictotermes cyphergaster (Blattaria, Termitidae) termite nests as substrates for lichen fixation in the semiarid region of northeastern Brazil
RESUMO Sementes de sabiá (Mimosa caesalpiniifolia Benth.) apresentam dormência tegumentar, dificultando a absorção de água e oxigênio, consequentemente retardando a germinação. Dessa forma, objetivou-se avaliar métodos para superação de dormência associados ao condicionamento fisiológico sobre germinação e vigor de sementes de sabiá, consider

3. Trade-off in plant-ant interactions: seasonal variations
Resumo Este trabalho avaliou o efeito da sazonalidade sobre a interação planta-formiga em uma Floresta Tropical Sazonal Seca, utilizando como modelo ecológico a espécie Ipomoea carnea subs. fistulosa (Convolvulaceae). Realizamos coleta sistemática de formigas, herbívoros e folhas em plantas marcadas, avaliamos a eficiência de captura de herbívoros pe

5. Population Fluctuation of Termitofauna (Blattodea: Isoptera) in Six Forest Fragments of the Mata Atlântica
ABSTRACT The objective of this work was to evaluate the forest restoration of the basin of Guapiaçu river in Cachoeiras de Macacu, Rio de Janeiro state, using the families of Termites as tools for environmental assessment. We analyzed the population fluctuation and feeding guilds of the families of Termites: Kalotermitidae, Rhinotermitidae and Termitidae. S

6. Gut anatomy of the worker caste of Neotropical genera Cylindrotermes Holmgren and Hoplotermes Light (Infraorder Isoptera, Termitidae)
ABSTRACT Studies over the last six decades have shown that the gut anatomy of the termite worker caste provides a valuable set of taxonomic characters. However, the gut anatomy of most American termitine taxa is still little known. This study investigated the anatomy of the worker gut of the Neotropical termitine genera Cylindrotermes Holmgren and Hoploterme

7. Biological Resistance of Two Reforestation Woods to Dry Wood Termites
ABSTRACT This work aimed to evaluate the biological resistance of Australian red cedar (Toona ciliata) and Eucalyptus woods to the Cryptotermes brevis (Kalotermitidae) dry wood termite species. The species used to evaluate natural resistance to insect attacks were Australian red cedar from 6 and 12-year-old plantations installed in the mountainous region of

8. First Report of Heterotermes longiceps (Blattodea: Rhinotermitidae) Termite in Teak Plantations
ABSTRACT Heterotermes longiceps termites was observed causing injuries in Tectona grandis plants in a forest plantation in Cáceres, Mato Grosso, Brazil. H. longiceps caused galleries below the bark, at the heartwood-sapwood interface, from the beginning of the root until approximately 1 m height tall and very infested plants has died. This is the first repo

9. Occurrence of Tectona grandis Stem Injury Caused by Cornitermes cumulans Termite
ABSTRACT Termites of the species Cornitermes cumulans (Kollar, 1832) were observed causing injuries in the stem of Tectona grandis in commercial forest plantations in Cáceres, Mato Grosso state, Brazil. C. cumulans forms galleries below the bark, at the heartwood/sap-wood interface of 1.8 years-old trees. This is the first occurrence of this type of injury

10. Sharing of termites (Blattodea: Isoptera) between sugarcane matrices and Atlantic Forest fragments in Northeast Brazil
Abstract The Atlantic Forest of South America is one of the most degraded tropical forests and the cultivation of sugarcane is considered one of the main causes. In humid forests termites stand out with regard to their abundance and functional importance. The present study aimed to compare termite assemblages of fragments of the Atlantic Forest with that of

11. State of knowledge of viviparity in Staphylinidae and the evolutionary significance of this phenomenon in Corotoca Schiødte, 1853
Abstract Viviparity is characterized by the retention of fertilized eggs in reproductive tract of the female. This condition is very common in vertebrates, but relatively rare in invertebrates, including insects. The present work presents a review on viviparity in Staphylinidae, with special attention on genus Corotoca Schiødte, 1853. The genus is composed

12. Efficiency of Vegetable Oils in Wood Resistance to Cryptotermes brevis Termites
ABSTRACT Natural products have been studied in order to ensure environmental sustainability, human health, and diminish the use of traditional products. The objective of this study was to evaluate the efficiency of pure andiroba (Carapa guianensis), copaiba (Copaifera langsdorffii) and jatropha (Jatropha curcas) oils and enriched with iodine (I2) on the biol
