EVALUATION OF NIFA BIO-LARVICIDE IN NATURAL HABITATS OF Culex quinquefasciatus UNDER FIELD CONDITIONS AT DISTRICT MARDAN
ABSTRACT:

Mosquitoes transmit severe diseases in human beings, causing millions of deaths every year due to dengue fever. Indiscriminate use of synthetic chemicals in indoor and outdoor of mosquitoes breeding sites has caused physiological resistance and adverse environmental effects in addition to high operational cost. But due to environmental constraints, health hazards and resistance development in mosquitoes, other environment friendly vector control strategies are important. Previous researchers have been reported the bio pesticides as useful for the control of mosquitoes larvae. NIFA bio-larvicide was applied in selected breeding habitats of Aedes aegypti and Culex quinquefasciatus under the field conditions and reductions in the densities of 3rd and 4th instars larvae were compared with that of untreated matched as controls. Three different concentrations were used as 25, 50 and 100ppm. The present work discusses the potential of this product as potential larvicides for the control of mosquitoes. The results showed that an application of the formulation at the rate of 125ppm provided 19.67% reduction followed by 50 and 100 ppm as 94 and 98 % of larvae in different selected breeding sites on day 1; thereafter 100% reduction was recorded at after 4 and 5 days in all the tested concentrations. This product was found effective in suppressing mosquito larval population in different breeding sites under natural field conditions.

RESPONSE OF MARIGOLD (Tagetes erecta L.) TO DIFFERENT LEVELS OF NITROGEN
ABSTRACT:

An experiment on “Response of marigold to different levels of nitrogen” was carried out at Bagh-e-Naran Park Peshawar, during 2013. Seedling of Marigold cultivar “Pygmy” were raised and transplanted on flat beds on 10th October 2013 at 30 cm Plant to Plant distance, while row to row distance was kept 60 cm. The seedlings were subjected to four different levels of nitrogen i.e., 0 (control), 70 kg ha-1, 90kg ha-1 and 110 kg ha-1. Data were collected on plant height, number of branches, number of leaves, days to flowering, number of flowers and flower weight. Different level of nitrogen had significantly affected most of the studied attributes. It is concluded from the findings of the research that application of Nitrogen at110 kg ha-1 resulted in tallest plants (22.80 cm) with maximum number of branches plant-1 (15.47), early flowering (22.33), maximum number of flowers plant-1 (23.22) and highest flower weight (20.66gm) that was statistically at par with the application of nitrogen at 90 kg ha-1.

DIFFERENCE IN THE RHIZOSPHERE BACTERIA OF ZINC-DEFICIENCY TOLERANT AND SENSITIVE RICE GENOTYPES AS A CONTRIBUTING FACTOR TO ZINC EFFICIENCY AT THE MICROBIAL LEVEL
ABSTRACT:

In an attempt to explain zinc deficiency tolerance at the microbial level, DGGE using 16S rDNA was used to compare the bacterial diversity in the rhizosphere of zinc deficiency tolerant and sensitive rice genotypes. The DNA from the rhizosphere of A69-1 and K. Patong (KP) at seedling stage was extracted and amplified using universal primers for bacteria and archaea. The 16S rDNA PCR amplicons were subjected to DGGE using 35-55% denaturation gradient of urea-formamide. The prominent bands were excised, reamplified and sequenced. A total of 36 bands, each band representing a microbial population, were observed. Only 17 bands were successfully excised and matched with the NCBI database. The sequences have 83 to 96% matches to 11 prokaryotes namely Methylococcus capsulatus, Methylomonas lenta, M. rubra, Methylomagnum ishizawai, Methylocaldum marinum, Methylogaea oryzae, Methylovulum miyakonense, Pseudoalteromonas xiamenensis, Halochromatium roseum, Thermofilum uzonense and Thermogladius calderae. The presence of relatively greater number of microbial population consisting largely of methanotrophs in the rhizosphere of A69-1 might contribute to its tolerance to zinc-deficient soil. Conversely, the sensitivity of KP to zinc-deficiency might be attributed to the relatively reduced microbial population.

PRODUCER KNOWLEDGE AND PERCEPTIONS OF HEALTH AND ENVIRONMENTAL RISKS RELATED TO URBAN AND PERI-URBAN AGRICULTURE ON WASTE DISPOSAL: THE CASE OF THE CITY OF BOBODIOULASSO (BURKINA FASO)
ABSTRACT:

The use of urban waste as fertilizer is dangerous for human health and the environment because of contamination of soil, water sources, plants and air by undesirable elements (heavy metals, toxic gases, pathogenic organism, etc.). The study was conducted at four garbage disposal sites in the city of Bobo-Dioulasso (Burkina Faso). The main objective of this study was to assess the knowledge and perceptions of producers about the health and environmental risks of using garbage disposal sites for agricultural production. The data was collected in a semi-structured interview with a site and producer interview guide. The results show that the majority of producers are married men with an age range between 47 and 57 years. Most have a very low level of education, with 36.36% out of school and 45.45% who have reached primary school. 100% of the respondents are aware of the risk of injury but a large number of producers 60 to 80% ignore the other health risks namely the risks related to contaminated food and chemical and microbiological risks. 50% of producers recognize the negative effects of their activities on animal life. At the environmental level, the proportion of those with knowledge of the presence of toxic elements in the air is very high at 93.93%. Only 34.80% of producers are aware of the risks of accumulation of toxic elements in crops. The analysis of perceptions reveals that less than 40% of producers agree that they have not observed any evolution of these diseases in their families and employees. The percentage of people with no information on animal health-pathology and death of animals is 57.57% and 63.63% respectively.
