Abstract

Bioinsecticide is an alternative to overcome larva resistence to insecticide and reduce environtment contamination. This research is to analyze the effect of areca seed extract to An. vagus larva. The research is taken time in 2017. The research design is laboratory experiment with post test only control group design. The areca seed and An. vagus larva are collected from Kabupaten Sumba Barat Daya, then the seeds were extracted with ultrasonic method. The effect of the extract is evaluated based on LC50 and LC90 value. The sample from 25 An. vagus larva instar III are released into areca seed extract on 500, 1250, 2000, 2750, 3500, 4250 and 5000 ppm and observed within 6, 12, 18 and 24 hours and 6 repetition. The data then analyzed with probit analysis and ANOVA. The areca seed extract eliminates An. vagus larva as much as 61.33% under 6 hours exposure with 5000 ppm, 52% larva mortality on 12 hours with 4250 ppm, 56% larva mortality on 18 hours with 3500 ppm, and 55% larva mortality on 24 hours with 2750 ppm. The value of LC50 and LC90 on 6, 12, 18 and 24 hours are 4654.374 and 6320,732; 3717.286 and 5127.489 ppm; 3201,473 and 4775,206 ppm; 2385,297 and 4496,708 ppm. There is variation of larva mortality percentage average on every concentration and exposure time, the higher the concentration and exposure time the higher An. vagus larva mortality.

Abstract

Malaria in Indonesia remains a significant health problem. Trenggalek District is one of the receptive malaria areas in East Java Province, Indonesia, with mainly imported malaria from outside Java Island. The people of this district accustomed to traveling to outside Java where malaria is endemic for temporary working purposes. Usually, they have acquired malaria infection in the areas where they worked and brought to their homeland during their return to the district. The number of imported malaria cases depend on the returning season of the workers. When no workers return from outside Java malaria case is zero. During the year of 2012-2016 microscopic examination of Microscopic examination of Giemsa-stained thick blood films of the workers have been done in the working activity of Pandean Primary Health Center on their arrival from Kalimantan Island either by active or passive case detection. Microscopically positive data were reported herein to describe the trend of imported malaria in the studied areas. A total number of malaria-infected workers were 118 cases. The trend towards increasing case number yearly between 2012 and 2013 being 1.35%, then decreasing between 2013 and 2016 to only 4 cases in 2016. Different patterns of imported malaria by month were seen in each year but no specific pattern throughout the year. The Plasmodium vivax infection was predominant every year and followed by Plasmodium falciparum and mixed infection of those two species. Trends of imported malaria cases in Trenggalek district were decreased and increased irregularly in each month yearly. However, the number of cases declined annually during 2013 – 2016. Antimalarial prophylaxis and insecticides prevent the workers from malaria infection.

Abstract

This research was aimed to describe the density pattern and the fluctuation of Aedes aegypti larval based on the season in dengue haemorrhagic fever (DHF) endemic area in Surabaya city. The population of the research was the house of people together with its breeding sites either inside and outside the house. The 55 houses were randomly chosen in 11 RWs in Nginden Subdistrict. The sample of this research was Aedes aegypti larva obtained from its breeding sites. The sample sizes were all of the larval in the containers existed in the chosen houses. The samples of the larval were taken and carried for identification and documentation of the species. This research was applied in the same houses in January, March, and May 2008 in rainy season. The results indicated that the highest larval index occurred in January with House Index (HI) 76.8%, Container Index (CI) 40.5%, and Breteau Index (BI) 137.5%. There was a decrease in March with HI 63.3%, CI 31.3%, and BI 92.7%. It continued to decrease in May with HI 42.6%, CI 21.1%, and BI 57.4%. All of those larval indices in the three observed months showed a high percentage of larval which was much higher than the safe limit or the critical threshold (5%) as defined by WHO. It implied that people in Nginden Subdistrict were threaten by the infection of DHF. The three indices achieved the peak in January, which was also the peak of the rainy season. It gradually decreased in March and May as the rainy season decreased its intensity of rain. Larval Density Index (LDI) also showed a high value. There were 173 larval/house in January, 187 larval/house in March, and 84.8 larval/house in May. The containers or breeding sites of Aedes were mostly found in January then their existences gradually decreased in March and May. Traditional bath tub was the most productive container inside the house, while drum and bucket were the most productive containers outside the house. Other containers which contributed abundance of larval were refrigerator, flower pot, well, and PDAM meter box.

Abstract

Dengue Hemorrhagic Fever (DHF) is caused by dengue virus and transmitted by Aedes aegypti mosquito. There are several fish species known to be used as a biological predator of Aedes aegypti larvae, such as Betta splendens. The purpose of this study was to examine Betta splendens as a biological predator of Aedes aegypti larvae. The larvae used were in the fourth stage. The Betta splendens consisted of four replicate groups, 3 and 6 months male age group, and 3 and 6 months female age group. The effectiveness rate of predation was only counted based on the speed of eating of 25 larvae in the aquarium containing 3 liters of water. Statistical test was performed with Annova with the parameters fish body weight and time to prey. The longest mean of preying time was found in 3 months aged male fish group (mean body weight = 1.474 grams), with a mean time of prey = 153.80 seconds. The shortest mean preying time was found ini 6 months aged female fish group (mean body weight = 2.566 grams), with a mean time of prey = 142.41 seconds. In conclusion, female 6 month-aged fish with highest mean body weight is most effective againts Aedes aegypti larvae. The body weight can affect the speed of preying, but body weight is only one of some variables that affect the speed and effectiveness beside gender and age of Betta splendens.

Abstract

Streptomyces sp. is a bacterium that can live in many kind of habitations e.i. marine, sea sponge, coastal area, soil, desert soil, river bank etc. Many antibiotics and secondary metabolites are produced by this bacterium. Several secondary metabolites of the bacterium can be used as an insecticide against insects including mosquito larva.The purpose of this study was to search and isolate until species of Streptomyces sp. from Sidoarjo Lapindo mud soil in East Java province that can be used as a larvicide against Aedes aegypti larva, the dengue haemorrhagic fever vector.The method of study was to collect several mud soil samples from Sidoarjo Lapindo. The collected samples were cultured in ISP-4 media for producing mix-cultures. Then, to isolate the suspected colony of Streptomyces sp. by culturing again in several replications on ISP-4 media in petri-dish. The pure isolates were cultured in ISP-4 slant media. There were could be obtained eight pure isolates of Streptomyces sp.The characterization of 16S rRNA of Streptomyces sp. was done in order to determine the species. DNA isolation was done and followed by DNA sequencing, then compared to Gene Bank with BLAST program. The results showed that the sequence nucleotide bases of Streptomyces Sp-D6 had high similarity to Streptomyces sp. 171524, beside the sequence nucleotide bases of Streptomyces Sp-D7 and Sp-D9 had high similarity to Strepto-myces sp. ACT-01578 and ACT-175695. These three species can be used as larvicide candidate against Ae. aegypti.
