Abstract

This research aims to find out the oviposition ability of Aedes aegypti L. mosquitoes in various settlements wastewater including household waste, industrial laundry, and tofu home industry. The descriptive method was used to count the number of mosquito eggs on each wastewater and to calculate the percentage of survival rate of mosquito from egg to larvae and from larvae to mosquito. Fifty pairs of the Ae. aegypti were applied to modified cageusing three water sources namely household waste, laundry, and tofu industry.In this research, rainwaterwas used as a positive control. The result showed that Ae. aegypti from settlement in Samarinda are able to lay egg in all tested wastes. Laundry wastewater is the most preferred medium based on the number of eggs (6,290 eggs) with percentage of survival rate from egg to larvae is 75.0 % (cage contains one wastewater) and 48.4% (cage contains more than one wastewater) and the percentage of survival rate of larvae become adult mosquitoes phase is 92.8% (cage contains one wastewater) and 90.0% (cage contains more than one wastewater). Keywords: preference, oviposition, Aedes aegypti, wastewater

Abstract

Study of effectiveness of Beauveria bassiana Powder as Larvacide to Aedes aegypti larvae was conducted on September 2016 to May 2017 in Ecologi and Systematics Animal Laboratory, Faculty of Mathematics and Natural Sciences, University of Mulawarman. This study aimed to determine the effect of Beauveria bassiana powder with use flour rice media on differents concentration as larvacide to mortality of larvae Aedes aegypti. Stages of study include arranged experimental design (Completely Randomized Design) with concentration of 0%, 0.125%, 0.25%. 0.5% and 0.75%, taking sample, rearing third instar larvae of Aedes aegypti and application Beauveria bassiana powder in 48 hours observation. The mortality value of larvae willbe presented on percentage tabel and graph. The result showed, this product is capable of killing larvae for 48 hours with the percentage mortality 0%, 10%, 28%, 70% and 80% in each concentration. Mortality of larvae is influenced by concentration and period of exposure. Increased of product concentration that given and period of exposure can effected increased of mortality percentage. Keywords: mortality, Beauveria bassiana powder, Aedes aegypti larvae

Abstract

AbstractThis study aimed to determine the composition and structure of Semayang forest and the Importance Value Index (IVI) of riparian forest in its role of reducing the wave rate. The method used is multilevel plot method of 20x20 m for sampling of tree level, 5x5 m for sapling level and 2x2 m for seedling level. The result showed that the highest Importance Value Index at tree level was dominated by 3 species, they were L. javanicum (101,663), M. speciosa (76,201) and G. renghas (65,962). At sapling level dominated by P. indica (102,990). At seedling level dominated by M. pigra (95,004)andP. brevistipitata (70,109). In addition, Semayang riparian forest has an ecological function as a wave retaining. It can be seen based on the vegetation density and horizontal structure of species that make up the forest. Vegetation density is predicted to reduce the rate of Semayang lake waves that occur during flood season. Keywords: Composition and Structure, Riparian Forest, Semayang Lake.

Abstract

The purposes of this study was to find out the effectiveness of commercial insecticides to German cockroaches. Study was conducted from September to November 2013 in the Laboratory of Animal Physiology, Department of Biology, Andalas University. This study used the contact method (glass jar) with three strains of German cockroaches (VCRU–WHO, GFA-JKT and PLZ-PDG) and five kinds of insecticide (ByWS, HtWS, MtWS, RdWS, and VpWS). The average of knockdown time and lethal time were counted with a probit analysis. The effectiveness category divided into two groups, value of knockdown time and lethal time were needed to be achieved in a certain time. The results showed that based on the value of knockdown time 90% (KT90), effective aerosol insecticide to knockdown the German cockroach is aerosol insecticide ByWS, HtWS and VpWS. Aerosol insecticide MtWS was only effective to knockdown the German cockroach VCRU-WHO strain and ineffective for GFA-JKT and PLZ-PDG strains. Aerosol insecticide RdWS was only effective to knockdown the German cockroach VCRU-WHO and GFA-JKT strains, ineffective for PLZ-PDG strain. Based on the lethal time 90% (LT90)  there was no single insecticide effective to kill German cockroach.

Abstract

The aim of this research is to gain further understanding of how particular insect species respons to different host plants. This research isconsidered as preliminary research in integrated pest management for Spodoptera exigua. We report herein the consumption and utilizationof green onion (Allium fistulosum), caisin (Brassica rapa subsp. Parachinensis) and celery (Apium graveolens) by Spodoptera exigua. Theevaluation of indices of food consumption, growth and food utilization showed that caisin (Brassica rapa subsp. Parachinensis) was the bestfood for the last instar larvae of S. exigua as compared with celery or green onion. Growth rates and efficiency of conversion of ingestedfood to biomass (ECI) were significantly higher for larvae fed caisin (11.93%) than for those given green onion (8.06%) or celery (7.74%)Although the protein content of caisin (2.23%) was a bit lower than that of green onion (2.45%) but higher than celery (1.28%), we suspectthat the larvae performed best in caisin due to good balance between protein and carbohydrate as well as water content in caisin as comparedwith other host plants.

Abstract

We examined the effectiveness of some insecticide aerosols to German cockroaches. This experiment was conducted at the Laboratory of Animal Physiology Department of Biology, Andalas University from July to October 2013. Animal subjects were three strains of German cockroaches, namely GFA-JKT from Jakarta, PLZ-PDG from Padang and VCRU-WHO from School of Biological Sciences, University Sains Malaysia. Those subjects were treated using spray method of five brands of commercial insecticides found in the market, namely ByWS, HtWS, MtWS, RdWS and VpWS. We analyzed  knockdown and lethal times using probit analysis. The effectiveness were evaluated based on running time to achieve the knockdown and lethal. The results showed that knockdown time (KT90) of ByWS, HtWS, MtWS, RdWS and VpWS were effective for VCRU-WHO and GFA-JKT strains and the only HtWS and RdWS were effective for PLZ-PDG strain. Based on the the lethal time (LT90)  there was no single insecticide effective to kill cockroach.Kata kunci: Blattella germanica, commercial insecticide, Spray Method, Knockdown.

Abstract

House flies (Musca domestica Linnaeus) is one of the common urban pests causing health, economics, and aesthetics problems. Although intensive control by using inseticides are carried out, there are reports of control failures, which are probably due to insect resistance. Bioassay tests with topical application to study the status as well as resistance mechanism of house flies collected from the city of Jakarta (JKT), Bandung (BDG), Yogyakarta (YGY) and Surabaya (SBY) to pyrethroid (permethrin) and carbamate (propoxur) insecticides were carried out. The results show that, as compared to the most susceptible strain (YGY), we found that BDG strain is highly resistant to permethrin with resistance ratio (RR) of 133.7 fold. SBY strain was the most resistant to propoxur with RR of 38.36 fold, followed by Bandung strain with RR of 18.22 fold. The addition of piperonyl butoxide (PBO) to either permethrin or propoxur in most of the strains caused a decrease in  LD50 values and increasing the synergist ratio (SR) suggesting that the detoxifying enzyme mixed function oxidase (MFO) played an important role in the development of resistance to permethrin and propoxur. Our study is the first report of M. domestica resistance to permethrin and propoxur in Indonesia.
