Biomass and population structure of Constrictotermes cyphergaster (Silvestri) (Isoptera: termitidae) in the dry forest of caatinga, northeastern Brazil Neotropical Entomology
Vasconcellos,Alexandre; Araújo,Virgínia F.P.; Moura,Flávia M.S.; Bandeira,Adelmar G..
Biomass and population structure of Constrictotermes cyphergaster (Silvestri) were studied in an area of dry forest of caatinga in the State of Paraiba, northeastern Brazil. Twelve nests of different sizes were randomly collected, being six during the dry season (November 2004 and 2005) and six during the wet season (March 2004). Soldier and worker populations varied between 4880 and 118800 individuals per nest. The ratio between soldiers and workers did not significantly vary between seasons. Biomass (measured as fresh weight) of individuals varied between 13.9 and 408.8 g per nest, and soldiers and workers had significantly greater biomass during the wet season. The estimated density of nests of C. cyphergaster was 59.0 ± 22.53 active nests/ha....

The chiggerflea Hectopsylla pulex (Siphonaptera: Tungidae): infestation on Molossus molossus (Chiroptera: Molossidae) in the Central Andes of Colombia Rev. Bras. Zool.
Ramírez-Chaves,Héctor E.; Tamayo-Zuluaga,Andrés Fernando; Henao-Osorio,Jose J.; Cardona-Giraldo,Alexandra; Ossa-López,Paula A.; Rivera-Páez,Fredy A..
ABSTRACT Some species of mastiff bats, Molossus Geoffroy, 1805, inhabit human shelters such as houses and barns. Among them, the Pallas’s mastiff bat, Molossus molossus Pallas, 1766, is the most common species in South America. There are a few studies on this bat in Colombia, mostly on colony size, diet, ectoparasite records, and activity patterns in the Andean and Caribbean regions. Here, we provide information on the prevalence of chiggerfleas, Hectopsylla pulex (Haller, 1880), on M. molossus, along with molecular data on the flea, and its distribution in Colombia. In addition, we describe the size and sex ratio of the infested bat colony, located in the central Andes of Colombia. The bat colony was represented by ca. 45 individuals, of which 33 were...
