“…This downward trend may be attributed to the modernization; rapid urbanization and use of pesticides in the agriculture sector. A rapid survey done by Kumar et al (1996) in and around Delhi in September 1994 at the time of plague outbreak in Surat does indicate the range of absolute flea index from 0.08 to 4.0. It was further stressed that it varies from place to place and the number of factors were responsible for this.…”

Rodent fleas have been considered as the main vector for plague transmission in the rodent population and human plague outbreak usually occur due to the close association of infected rodent fleas with the human being. A total of 910 fleas were retrieved from the 2128 rodents collected from the different areas like Kolar, Palamner, Pune, Surat, Rohru and Chennai. Mainly two types of rodent fleas i.e. Xenopsyalla astia and X. cheopis were found in these areas except the Dodra Kawar area of H.P. state. In Dodra Kawar area Neopsylla kawar species were found and it was very sensitive to the temperature variation. Dodra kawar area usually remains under snow for about nine months and even in the rest of period the maximum temperature does not go more than 20 o C. The distribution of X. astia and X. cheopis were found uneven. In surat of Gujarat state X. cheopis was predominantly high, whereas in rest of the area X. astia were found more. In Chennai the main species found was X. astia only. The female percent of rodent flea may be considered as a good indicator for the fast propagation of rodent flea. The breading season for the fleas mostly depends on the climatic condition like temperature below 22 o C-25 o C, humidity more than 70% even if the outside temperature is more still the shady area the favorable and do help in the survival of fleas. The rapid urbanization and mass use of pesticide in agriculture sector has got significant impact on the rodent flea population and development of resistance to pesticides.

Studies carried out on entomological and rodent surveillance in agroclimatic and feral biotopes of five districts of Maharashtra and two districts of Gujarat revealed that the terrain features of the seven districts surveyed were conducive to wild rodent species, Ta tera indica, a natural reservoir of plague and vector flea species, Xenopsylla cheopis. A total of 214 Tatera indica and three Bandicoota bengalensis were collected from burrows by the digging method and 89 rat fleas were retrieved. The flea index calculated ranged from 0.26 to 1.0 in different districts. The examination of blood serum samples, contact tissue impression smears and tissue organs (heart, lung, liver and spleen) of these wild rodents did not reveal any evidence of plague activity. The natural harbourages of Ta tera indica were found to be elevated land or raised margins of agricultural fields or barren land with thorny bushes/xerophytic plants and parthenium grass. Agricultural fields having wet soil were found to be the preferred harbourages of Bandicoota bengalensis. Movement of wild rodents toward human settlement was observed to be the common phenomenon during the harvesting season which may lead to the creation of favorable conditions for plague outbreaks.
