Most of thrips from Thripidae family are pests on horticultural crops. To date, there are no records in the species richness of thrips in horticultural crops. The aim of the research is to conduct inventory on thrips spp diversity that are associated with horticultural crops in West Java. Sampling were done in several horticultural crops areas in Bogor, Cianjur, and Lembang (West Bandung). The identification process began with sample slide preparations along with the documentation of the character from each species. The identification was done mainly by using the identification program Oztrips and some other published identification keys. Identification key was built based on diagnosis characters of each species. The results found there were 15 species, that are Ceratothripoides brunneus, C. revelatus, Frankliniella intonsa, Megalurothrips typicus, M. usitatus, Scirtothrips dorsalis, Thrips aspinus, T. coloratus, T. hawaiiensis, T. javanicus, T. malloti, T. palmi, T. parvispinus, T. sumatrensis, and T. unispinus. T. aspinus and C. revelatus were new record for Indonesia.

Studies on soil-dwelling predatory arthropods were carried out in lowland areas of South Sumatra, with objectives to analyze the species diversity and abundance of the predatoryarthropods inhabiting fields applied by synthetic insecticide, bioinsecticide, and without insecticide application. The predatory arthropods were sampled using pitfall traps. Indices of diversity and community similarities were applied to analyze the data. Results indicated that the arthropods inhabiting field without insecticide application had the highest diversity and abundance compared to other treatments. Predatory community similarities between those on the field without insecticide application and applied by bioinsecticide were higher compared to the fields applied by synthetic insecticide.

The effect of Bacillus thuringiensis to the mortality of corn stemborer Ostrinia furnacalis (Lep. Pyralidae). The study was conducted at the laboratory of Bogor Research Institute for Agricultural Biotechnology and Genetic Resources during 2005. The objective of this study was to evaluate the effect of the dosages of Bacillus. thuringiensis var. aizawai and var. Kurstaki on the mortalities of larvae of corn stemborer Ostrinia furnacalis. Completely randomize design was used with seven treatments. Each treatment was repeated four time with ten larvae per replication. The treatments were three formulation dosages of B. thuringiensis var. aizawai, i.e. 0,5; 1,0; and 2,0 g/l, thee formulation dosages of B. thuringiensis var. Kurstaki, i.e. 0,5; 1,0; and 2,0 g/l, and untreated control. Second instar larvae of O. furnacalis was used in this study. B. thuringiensis was contaminated to the surface of artificial diet with a small paint brush. The result showed that B. thuringiensis var. kurstaki at the dose rate of 1,0 g/l was toxic to the test insect while B. thuringiensis var. aizawai at the dose rate of 2,0 g/l was toxic to the test insect B. thuringiensis var. kurstaki was more toxic than B. thuringiensis var. aizawai to the corn stemborer.

Sibling species identification is very important in the understanding of malaria epidemiology. Morphological criteria are usually used in the identification of anopheline species, but this fails when sibling or cryptic species occur. Analysis by PCR-RFLP of rDNA ITS2 is currently the most reliable and sensitive method for distinguishing between members of the Anopheles punctulatus group. The objective of this study was to investigate the effect of DMSO concentration on ITS2 amplification of An. farauti from the colony maintained at BATAN Jakarta using PCR-RFLP based on the rDNA ITS2. The results showed that the addition of 6 % and 7 % DMSO produced ITS2 amplification products in the size 750 bp. DMSO could be used in PCR to relieve secondary structures when amplifying high GC templates. Molecular identification of An. farauti is found to be Anopheles farauti sensu stricto.

We studied the distribution of the Yellow Crazy Ant (Anoplolepis gracilipes) Smith (Hymenoptera: Formicidae) in Bogor Botanical Garden (BBG). Biological invasions by A. gracilipes can negatively impact other species. Individual nests of this ant can form supercolonies within which aggression is absent, intraspecific aggression occurs between workers from different supercolonies. The aim of this research was to study aggression between and resource discovery of different A. gracilipes supercolonies in BBG. Intraspecific aggression was calculated as three different aggression indices obtained by performing intercolonial arena encounters. Resource discovery was measured as time until honey baits in known distances to colony entrances were discovered. In 2013, we encountered five spatially distinct nest clusters of A. gracilipes in BBG, which cover ca. 25% of its area. Aggression tests showed that workers from KRB 1 were significantly more aggressive towards each other. The absence of intercolonial aggression between three of five nest clusters suggested that they actually belong to the same supercolony. On average, A. gracilipes needed less than 1 hour to find the food on bait plate in 20 m distance. We found 3 supercolonies of A. gracilipes which derived from 5 spatially distinct cluster of nests in BBG.

The research was conducted in the field of Taro village Gianyar regency and Katung village Bangli regency and at the Laboratory of Biotechnology Faculty of Agricultural Udayana University. The purpose of the research were to investigate population dynamic of Diaphorina citri Kuwayama and other insects that were assosiated with citrus cv. siam; and molecular detection of CVPD patogen in its vector, other phytophagous insects on citrus cv.siam and kemuning [Murraya paniculata (L.) Jack.] The result of this study showed that in six month period there was one peak of D. citri population which was associated with the flushing period of citrus at Taro as well Katung villages. The peak of D. citri population of Taro village was higher than that of Katung village. Two species of parasitoids and four spesies of predators were found in the field and may contribute in the suppression of D. citri population. The parasitoids identified were Tamarixia radiata Wat. and Diaphorencyrtus alligharensi Shaffe, whereas the predators were Curinus coeruleus Mulsant, Phiddipus sp., Menochilus sexmaculatus Fabricius and Oxyopes javanus Thorell. T. radiata has been proven to be an effective nymph parasitoid that could suppress the population development of D. citri in citrus orchads. The research revealed that kemuning could serve as a source of infection because it is also a host of CVPD disease as well as of D. citri. Toxoptera citricidus Kirkaldy and Maleuterpes dentipes Hell. were not proven to contain CVPD disease.

Datura metel L. is a type of shrub that has a wooden stem, hard, and thick. Datura leaves contain chemical compounds alkaloids, saponins, flavonoids, and phenols. Based on the chemical content, datura leaves potentially as an alternative insecticide that can replace the use of synthetic insecticides. The use of synthetic insecticides in controlling the Aedes aegypti L. population has had a negative impact, such as environmental pollution, public health problems, and vector resistance. The purpose of this study was to study the effect datura leaf extract as a biochemical insecticide on inhibiting egg hatching and life cycles of Ae. aegypti. The research was conducted at Entomology Laboratory, Public Health Faculty, Universitas Diponegoro. This type of research was a true experiment with four replications and with concentration treatment i.e. 125, 250, 500, 750, 1000, and 1250 ppm. The subjects of this study were egg fertile of Ae. aegypti which were 25 eggs in each container and the total number of samples was 800 eggs. The used method for extraction was maceration. The result of probit analysis showed the activity of amethyst extract insecticide with LC50 = 199.34 ppm and LC90 = 749.08 ppm. The result of ANOVA showed a difference in the average number of non-hatching eggs due to exposure of datura leaf extract (P = 0,001). The percentage of Ae. aegypti egg hatching failure was lowest at concentration 125 ppm (41%) and the highest was at concentration 1250 ppm (98%). The survival of larvae, pupa, and mosquitoes was highest at concentration 125 ppm (49.18%, 55.17%, and 43.75% respectively). In conclusion, the datura leaf extracts potentially as a biochemical insecticide that inhibits eggs hatching and life cycles of Ae. aegypti.

In the last three decades, there has been a four fold increase of dengue incidence globally. The control of the disease depends heavily on controlling the vector. Therefore, it is necessary to develop an ecological data of vector to identify the population density of the mosquitoes. One method to study the density and presence of the mosquitoes is through the use of ovitrap. The aim of this research is to identify the effect of two different types of ovitraps. One hundred and eighty ovitrap consist of coconut shell and glass ovitrap were placed in three different subdistricts which was selected based on the Incidence Rate of DHF in the district of Purwokerto City. The container indices and eggs density were compared between two types of ovitrap. Research was conducted using experimental quasy and the data were analyzed with the Mann-Whitney test. The total amount of eggs from coconut shell ovitrap were 9328 of eggs were obtain from 51.33 of ovitrap while the total amount of eggs from glass ovitrap only 1858 of eggs were obtain from 29 ovitrap. Statistical test showed significant difference between the amount of eggs of coconut shell higher than the glass. Mosquitoes prefer natural coconut shell ovitrap compared with artificial ovitrap so we recommended that to eradicate the mosquitoes nest, should not only artificial containers but also natural container to be managed in order to control the dengue vector.

There are approximately 1.4 million hectares of swampy area in South Sumatera, but only 12% of those are being used as farm and plantation. The purpose of this research was to investigate the similarity of arthropod community inhabiting swampy rice field and its surrounding area. This research was conducted in South Sumatera Province covering regency of Musi Banyuasin and Palembang. Four types of swampy area were selected from each location, i.e. rice field, thicket, bush, and swampy land inhabited by broad-leaf weeds. Pitfall trap used to collect arthropod and it installed at five different times. i.e. 15 days before rice planting, one month, two months, and three months after planting, and 15 days after harvest time. The result showed that relative abundance of predatory arthropod dwelling soil in rice field was 95.03%, and habitat surrounding rice field was 95.12–97.21%. The level of similarity of arthropod species between rice field ecosystem and its surrounding area ranged from 0.73 to 0.84. Thus, the surrounding area of rice field probably can be used as catchment area of predatory arthropod and other pests during planting season.

A field study was conducted at paddy fields in Petarukan and Pekalongan regencies of Central Java province during wet season crop 1989/90 and 1990/91 to elucidate population dynamic of whitebacked planthopper, Sogatella furcifera Stí¥l. Seven and three observation fields were set up in 1989/90 and the 1990/91, respectively. Cisadane rice cultivar was transplanted following the usual farmer's parctices except that no pesticide was applied. The population of the whitebacked planthopper and the brown planthopper, (Nilaparvata lugens Stí¥l) were sampled by using an insect suction catcher, a farmcop. Identification of generation was based on thermal constant required by the whitebacked planthopper to complete one generation and mean population density was calculated by graphical method. Two distinct seasonal population growth patterns were identified. The population with short population growth pattern completed four generations in one crop season in which their population density increased consecutively in two generations since immigrant generation, and thereafter decreased. The population with long population growth completed five generations in one crop season in which their population density increased consecutively in three generations, and thereafter decreased. The density of brachiptera adults determined 90% of the total population density. The proportion of brachiptera adults were not correlated with large nymphal density in both vegetative and generative stages of rice. The proportion of brachiptera adults showed significant negative linear regression with population density of the brown planthopper. Therefore, interspesific competition determined the proportion of wingform and population dynamics of the whitebacked planthopper.
