Dengue fever is an arbo-viral infection, widespread all over the world. In 21th Century, there is no safe affordable and effective vaccine accessible yet; vector control is that most effective method for the control of the disease Objective: To determine the susceptibility status of wild and laboratory strains larvae and adults of Aedes aegypti against different group of insecticides in Lahore city. Method: From Lahore sites, larvae were collected where insecticides used for wild strain at high frequency and quantity. The Insectary of National Institute of Malaria Research and Training (NIMRT), Lahore, Pakistan, adults and larvae were collected for laboratory strain.The laboratory strains for larvae bioassays were used. The mosquitoes populations indoor and outdoor collected in 2009, hatched from larvae into adults insectary in Lahore, Pakistan. During this study, four major insecticides groups are used which include Pyrethroids (Deltamethrine 2.5% SC), Neonicotenoids (Imidacloprid 5% SC), Phenyl-pyrazoles (Fipronil 2.5% EC) and Organophosphates dichlorvos (DDVP 50% EC). For data analysis, Minitab statistical software (Version 13.20) used for data expressed as mean ± S.E.M from bioassays. By using EPA Probit, LC was estimated with 95% confidence. The 50 statistically significant p value was <= 0.05. For comparing the concentrations of insecticides, Duncan's multiple range tests was used with significant difference (5% level) using at New Costat. Results: Different location of Lahore samples, Imidacloprid the most toxic to Aedes aegypti's wild strains on the other hand while Fipronil was also active for wild larval samples. Deltamethrine showed least activity against both adults and larval strains. The susceptibility of the eld strains was lower than laboratory strains; resistant ratio varies from insecticide to insecticide. In reporting results, mosquitos' population was resistance because of infrequent and incomplete coverage. Conclusions: This study concluded that Pyrethroids and agriculture pest control play role in indirect growth of insecticides' classes.

Dengue is vector-borne diseases with 390 million infections per year extending over 120 countries of the world. Aedes aegypti (L.) (Diptera: Culicidae) is a primary vector for dengue viral infections for humans. Current focus on application of natural product against mosquito vectors has been the main priority for research due to its eco-safety. The extensive use of chemical insecticides has led to severe health problems, environmental pollution, toxic hazards to human and nontarget species, and development of insecticide resistance on mosquitoes. Azolla pinnata is an aquatic fern and predominantly used as feed in poultry industry and as fertilizer in agricultural field for enhancing the fertility of rice paddy soil. The present study was conducted to explore the larvicidal efficacy of A. pinnata using fresh and powdered form against late third-stage larvae (6 days, 5 mm in larvae body length) of Ae. aegypti (L.) (Diptera: Culicidae). The larvicidal bioassays were performed using World Health Organization standard larval susceptibility test method for different concentration for powdered and fresh A. pinnata. Powdered A. pinnata concentration used during larvicidal bioassay ranges from 500ppm to 2000ppm; meanwhile, fresh A. pinnata ranges from 500ppm to 9,000,000 ppm. The highest mortality was at 1853 ppm for powdered A. pinnata compared with fresh A. pinnata at 2,521,535 ppm, while the LC50 for both powdered and fresh A. pinnata recorded at 1262 ppm and 1853 ppm, respectively. Finally, the analysis of variance (ANOVA) showed significant difference on Ae. aegypti larval mortality (F=30.439, df=1, p≤0.001) and concentration (F=20.002, df=1, p≤0.001) compared to powdered and fresh A. pinnata at 24-hour bioassay test. In conclusion, the powdered A. pinnata serves as a good larvicidal agent against Ae. aegypti (L.) (Diptera: Culicidae) and this study provided information on the lethal concentration that may have potential for a more eco-friendly Aedes mosquito control program.

Diarrhea is defecation with a frequency more often than usual (three times or more) a day (10 mL/kg/day) with a soft or liquid consistency, even in the form of water alone. Pathogenic bacteria, such as Escherichia coli, Salmonella typhimurium, and Shigella sp., play a role in many cases, to which antibiotics are prescribed as the first-line therapy. However, since antibiotic resistance cases are often found, preventive therapies are needed, such as consuming yogurt, which is produced through a fermentation process by lactic acid bacteria (LAB). This research aimed to determine the activity of lactic acid bacteria (Liactobacillus bulgaricus and Streptococcus thermophilus) in yogurt in inhibiting the growth of the pathogenic bacteria E. coli, S. typhimurium, and Shigella sp. The research applied in vitro with the liquid dilution test method and the true experimental design research method with post-test-only and control group design. The design was used to see the inhibitory effect of yogurt LAB on the growth of E. coli, S. typhimurium, and Shigell sp. to compare the effect of several different yogurt concentrations, namely 20%, 40%, 60%, and 80%. The results of the Least Significance Different analysis showed that there was a significant difference between yogurt with a concentration of 0% and that with various concentrations in inhibiting the growth of E. coli, S. typhimurium, and Shigella sp. with a p-value of &lt;0.05.
