| population interactions between culex vishnui mosquitoes and their natural enemies in pondicherry, india. | population interactions among mosquitoes in the culex vishnui subgroup, which are vectors of japanese encephalitis, and their natural enemies were studied in pondicherry, india. we tested the hypothesis that the breakdown of interactions between the larvae and their natural enemies due to drought followed by rain was responsible for the sudden increase in the vector population above the threshold for disease transmission during the heavy rainy period. we randomly sampled mosquito larvae and thei ... | 2006 | 16859094 |
| assessment of heavy metals (cd and pb) and micronutrients (cu, mn, and zn) of paddy (oryza sativa l.) field surface soil and water in a predominantly paddy-cultivated area at puducherry (pondicherry, india), and effects of the agricultural runoff on the elemental concentrations of a receiving rivulet. | the concentrations of toxic heavy metals-cd and pb and micronutrients-cu, mn, and zn were assessed in the surface soil and water of three different stages of paddy (oryza sativa l.) fields, the stage i-the first stage in the field soon after transplantation of the paddy seedlings, holding adequate amount of water on soil surface, stage ii-the middle stage with paddy plants of stem of about 40 cm length, with sufficient amount of water on the soil surface, and stage iii-the final stage with fully ... | 2013 | 23435848 |
