Correlation of Host Specificity, Environmental Factors and Oriental Rat Flea Abundance.
Fleas are the vectors of many communicable diseases that are normally found in oriental rats. Climate and environmental changes influence the habitat and migration patterns of vectors. In this study, the oriental rat flea abundance, represented as total flea index, was determined in correlation to host specificity and various environmental factors. The number of hosts and fleas calculated from ...
متن کاملInsights Into Flea Beetle (Coleoptera: Chrysomelidae: Galerucinae) Host Specificity From Concordant Mitochondrial and Nuclear DNA Phylogenies
Flea beetles in the genus Altica are herbivorous, urban agricultural pests that are morphologically difÞcult to distinguish. Host plant associations, therefore, have been used as an important species character in Þeld studies. Indigenous weeds in the Onagraceae, genus Oenothera, are known to serve as developmental hosts for the ßea beetle Altica litigata Fall. Although host plant speciÞcity in ...
متن کاملHost Specificity of Cuscuta reflexa Roxb. in the Manas Biosphere Reserve, Indo-Burma Hotspot
The dodder plant Cuscuta reflexa Roxb. is an angiospermic leafless parasitic plant belonging to the family Cuscutaceae is abundantly found colonizing certain plant species in the premises of Manas Biosphere Reserve (MBR) and nearby area. Ten (10) angiospermic host plants in total of the above parasite were recognized. Based on the field inspection most of the numbers of patches were recorded in...
متن کاملBeta-specificity: the turnover of host species in space and another way to measure host specificity.
Host specificity is often measured as the number of host species used by a parasite, or as their phylogenetic diversity; both of these measures ignore the larger scale component of host use by parasites. A parasite may exploit very few host species in one locality but these hosts may be substituted for completely different species elsewhere; in contrast, another parasite may exploit many host s...
متن کاملHost specificity of parasite manipulation
Recently we presented how Camponotus ants in Thailand infected with the fungus Ophiocordyceps unilateralis are behaviorally manipulated into dying where the conditions are optimal for fungal development. Death incurred in a very narrow zone of space and here we compare this highly specific manipulation with a related system in Brazil. We show that the behavioral manipulation is less fine-tuned ...
