Field trial of the effectiveness of indoor-spraying with pirimiphos-methyl emulsion for malaria control in a tribal area of Phulbani district, Orissa State, India

A field trial of malaria vector control was conducted in Phulbani district, Orissa, during 1984 and 1985. Indoor-spraying of pirimiphos-methyl emulsion formulation was undertaken at an application rate of 2 g/m2 in two sections (population 14,692) of Nuagaon Primary Health Centre. Houses in two adjacent sections (population 21,450) were sprayed with DDT a water dispersible powder (wdp) formulation at 1 g/m2 for comparison purposes. Operational problems in this area come from the tendency of tribal people to re-plaster over wdp applications. Pre-spray malariological indices in the trial area were 38% slide positivity rate, 37% slide falciparum rate and 12.1% annual parasite incidence. Densities of Anopheles annularis Van der Wulp, An. culicifacies Giles, An. fluviatilis Theobald and other potential malaria vectors were reduced in the pirimiphos-methyl trial area 2-35-fold more than in the area sprayed with DDT. Malariological indices were reduced by 65-68% in the pirimiphos-methyl sprayed area compared with only 26-35% reduction in the DDT sprayed area. Spraymen and villagers experienced no adverse side-effects from residual house-spraying with pirimiphos-methyl emulsion and it is concluded that this organophosphate product has advantages for malaria vector control, especially in operationally difficult situations.     

Paleoclimatic Analysis of Paleogene Flora in Yilan County,Heilongjiang

Plant fossils were collected from the sand-shale above the lower coal seam and the upper oil shale above the upper coal seam in the Yilan coal mine, Heilongjiang. The floras contained 2 species of pteridophytes, 10 species of gymnosperms and over 58 species of angiosperms assigned to 46 genera and 34 families. The fossils were divided into two floras, one of which was in lower sand-shale beds, with the age assigned to the Eocene, and the other was in the upper part of oil shales considered to belong to the Oligocene. The floras were complicated in composition and rich in species, and were studied by means of floristic analysis, foliar architectural and physiognomical analysis. The Eocene flora consisted of many evergreen broad-leaved species, which indicated that the flora belonged to north subtropical evergreen broad-leaved forest or subtropical coniferous and broad-leaved mixed forest. The foliar physiognomical analysis of the floristic composition showed that the species with entire leaf margines made up 38.3 percent of the total. The climate in the Eocene was estimated by means of climatic nomogram as follow: The mean annual temperature was 13.2 ℃ and annual temperature deviancy was 20℃. In the Oligocene flora, deciduous broadleaved trees were dominant, which indicated that the vegetation was of temperate deciduous broad-leaved forest or warm temperate coniferous and deciduous broad-leaved mixed forest. The species with entire leaf margines were 30. 8 percent with an estimated mean annual temperature of 11 ℃ and mean annual temperature deviancy of 25 ℃. The floristic aspect and climate in the Paleogene of Yilan region were very different from the present ones.     

The delineation of fertility strategies in a tribal population of India: the Koyas of Koraput District,Orissa

Demographic data collected for a tribal population of India, the Koyas of Koraput District, Orissa, were examined in light of 2 models of reproductive behavior associated with the economic value of children: the replacement effect and son survivorship motivation. Both models are united in the concept that infant/child mortality affects subsequent fertility. The database consists of retrospective fertility histories of Koya women who had completed their reproductive period. The total number was 260, with the total offspring numbering 1407. 2 distinct cohorts of women were formed for the purpose of analysis, separated only by the criterion of offspring survival: women who had experienced infant child mortality (129 women with 739 children); and women who completed their reproductive period without suffering offspring loss of this nature (132 women with 668 children). The cohort without child loss had a mean parity of 5.10, lower than the average parity of 5.73 recorded for the cohort whose reproductive histories included at least 1 infant/child death. Age specific marital fertility and birth interval analyses indicated that this differential was because of biological, not behavioral, factors. The age pattern of fertility of females suffering offspring mortality failed to demonstrate a high rate of childbearing in the later age intervals of the reproductive period, a characteristic pattern of couples attempting to "replace" lost offspring. Birth interval analysis pointed to biological "interval effect," whereby infant/child mortality caused a cessation of lactation and hence a shortening of postpartum amenorrhea. Computer simulation further indicated that the higher fertility differential of the cohort experiencing offspring loss still did not result in high son survivorship values. The findings agree with earlier studies indicating that for predemographic transitional populations, economically motivated fertility strategies are ineffectual.     

Ex-Situ Cultivation of Medicinal Plant Species in High Altitudes at Swat,Pakistan

An ex-situ experiment was conducted to evaluate the growth performance of six medicinal species (Bergenia ciliata, Valeriana jatamansi, Dioscorea deltoidea, Paeonia emodi, Polygonum amplexicaule and Viola serpense) from upper Swat , Pakistan . Experiments were conducted at four different locations in the upper Swat valley at altitudes ranging from1200 to 1900 m. a. s. l . The objectives were : 1) to determine the suitability of ex-situ cultivation of different medicinal species, and; 2) to assess the economic geasibility of growing medicinal plants in the area . A highest mean survival of 80.7% across all locations was observed for Viola serpense, followed by 58.7% for Valeriana jatamansi. The remaining four species exhibited very poor survival rates , although Polygonum amplexicaule, did show encouraging signs of growth and flowered , before experiencing high mortality rates late in the trial . Altitude generally seemed to enhance the degree of sprouting for all species except Viola serpense. However, the productive yield of V. serpense was certainly not reduced, but rather slightly enhanced in the higher altitude sites. Overall, cultivation of only two of the investigated species, Valeriana jatamansi and Viola serpense, appearedsuccessful and potentially economically viable under farmland conditions at upper Swat .     

Disappearance of malaria vector Anopheles sundaicus from Chilika Lake area of Orissa State in India

Malaria has declined around Chilika Lake (85°20′ E, 19°40′ N) in Orissa State, India, from hyperendemicity in the 1930s to hypoendemicity during recent decades. Six decades ago, 21 spp. of Anopheles mosquitoes (Diptera: Culicidae) were recorded from this area, including the well known Indian malaria vectors An. culicifacies Giles, An. fluviatilis James, An. maculatus Theobald, An. stephensi Liston and An. sundaicus (Rodenwaldt), the last formerly regarded as the main vector locally. Surveys of Chilika area during 1995–96 found 8 spp. of culicine plus 14 spp. of anopheline mosquitoes, the latter comprising An. subpictus Grassi sensu lato, An. hyrcanus (Pallas) s.l., An. vagus Dönitz, An. annularis van der Wulp s.l., An. culicifacies Giles s.l., An. aconitus Dönitz, An. varuna Iyengar, An. barbirostris van der Wulp s.l., An. philippinensis Ludlow, An. ramsayi Covell, An. jeyporiensis James, An. pallidus Theobald, An. tessellatus Theobald and An. karwari James in decreasing order of abundance. Among indoor‐resting female mosquitoes, the anthropophilic index was 4–7% and some species (An. culicifacies, An. subpictus, An. vagus) tended to enter houses for resting after blood‐feeding outside. Females of potentially infective age (three‐parous) were obtained for An. culicifacies (11%) and An. annularis (< 2%), the more abundant established vector in this coastal area, but not for small samples of An. subpictus and An. vagus. Anophelines reported previously but not found in our survey were An. fluviatilis, An. jamesii Theobald, A. maculatus, An. splendidus Koidzumi, An. stephensi, An. theobaldi Giles and the former main vector An. sundaicus.     

AM Fungal Diversity in Selected Medicinal Plants of Kanyakumari District,Tamil Nadu,India

The association of Arbuscular Mycorrhizal Fungi (AMF) with three medicinally important plants viz., Eclipta prostrata, Indigofera aspalathoides, I. tinctoria collected from three different localities of Kanyakumari District, South India was examined. The study reports the colonization percentage, diversity and species richness of different AM fungi in the rhizosphere of the three medicinal plants and discusses the impact of soil physicochemical characteristics such as soil texture, pH and available macro- and micro nutrient content on AM fungal communities. A total 21 AM fungal species were identified in field conditions of the three plants from three sites. AM fungal species richness, colorization percentage and Shannon index were found to be high in the two Indigofera sp. growing in the hilly areas of Kanyakumari District and were low in E. prostrata collected from the damp regions in the foothills of the three study sites. Five species registered 100% frequency in all the study sites of the three medicinally important plants with Glomus as the dominant genera. The study states that the mean colonization and diversity patterns were dependant on edaphic factors and type of vegetation.
