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.

Collembola is one of the dominant microarthopods in almost all soils types. They have important function in food webs soil ecosystem. This research was done at Cikasungka oil palm plantation for six months (April until September 2014). The aim of the research was to collect the information of diversity abundance and population fluctuations of Collembola, and their linkages between environmental factors. Collembolans were collected based on four points of soil sample from five trees of oil palm which has similar criteria. Distance of 0, 120, 240 cm from the trees, and compost lane were used to collect the samples. Results showed 37 species from 10.438 individuals with a density of 544 individu/m2. The species belongs to 4 orders and 13 families. Result also showed that are fluctuations in the abundance at the sample sites. The highest abundance of Collembolans was found in base tree zone (920 individu/m2) and compost lane (763 individu/m2). During six months, total populations of Isotomid sp. 5 (Isotomidae) was higher than the others species of Collembolans. Based on the correlation analysis, various species of Collembolans are positively correlated with rainfall and soil pH.

Intervillage variation of malaria endemicity in the same sub-district is probably related to infectivity variation of Anopheles sp. The purpose of this research was to examine the proportion of sporozoite positive species, or species infectivity (SI), and the proportion of sporozoite positive samples, or total sporozoite index (TSI), of a high endemic village (HEV) and a low endemic village (LEV) in the Kokap Sub-District, Kulon Progro District, Central Java. Four Anopheline species were examined - Anopheles vagus Donitz, Anopheles maculatus (Theobald), Anopheles balabacensis Baisan, and Anopheles aconitus Donitz. Anopheles mosquitoes were concurrently collected in the two villages, five times each during October–December 2013, at two-week intervals, using the resting collection method. The mosquito collection was conducted every hour (50 minutes each) at three houses by two collectors each (one inside and one outside), from 18:00 PM to 06:00 AM. Female parous mosquitoes were examined using the Multiplex-PCR method to detect the presence of sporozoites. The examination of 77 DNA samples showed that the SI and TSI of the two villages (49 HEV and 28 LEV) were significantly different: a SI ratio of 66,7% : 33,3% and a TSI ratio of 20,41% : 3,57% (OR = 6,9; CI95% = 0.87 to 57.29; p = 0.021). This finding indicates that a high intensity malaria transmission could occur in the HEV and that a specific vector control measure is necessary.

Evaluasi pelepasan Trichogramma spp. untuk pengendalian penggerek pucuk dan batang tebu Nurindah Nurindah; Dwi Adi Sunarto; Sujak Sujak

The success and effectiveness evaluation of Trichogramma releases for controlling sugarcane top borer (Scirpophaga excerptalis (Walker)) and stalk borers (Chilo spp.) have not been intensively evaluated. This research was aimed to evaluate the control technique of sugarcane borer complex by releasing Trichogramma spp. The evaluation approach was performance tests of the parasitoid fitness through determination of reproductive rate and parasitism capacity of the parasitoids. Field observations were also done to obtain the borers’ egg parasitism level in Trichogramma released and unreleased sugarcane fields. The observation was done by collecting the borers’ eggs in such fields and egg parasitism level was recorded. Results showed that releases of Trichogramma chilonis Ishii or Trichogramma japonicum Ashmead were not effectively caused egg parasitism on S. excerptalis or Chilo spp. A hundred % parasitism of S. excerptalis eggs and 77% parasitism of Chilo spp. were caused by Telenomus sp. T. chilonis parasitized only Chilo spp. Reproductive performance of T. japonicum indicated a low reproduction capacity. Mass releases of Trichogramma spp. for controlling the sugarcane borers’ complex in Indonesia has to be reconsidered by taking into account the species and release technique to obtain a successful biocontrol of sugarcane borers’ complex.

Chrysanthemum (Chrysanthemum indicum) as one of horticultural commodities has a good prospect to be developed as source of country revenue. The export of cut flowers of chrysanthemum from Indonesia tends to increase year by year. However, Thrips parvispinus Karny (Thysanoptera: Thripidae) which is major insect pest of chrysanthemum often attacks this flower in the field until postharvest causing the decrease of quality of flowers. The poor quality of cut flowers of chrysanthemum including the presence of T. parvispinus will be rejected by foreign businesses. Therefore, control measures of this insect pest by quarantine officers are important. Treatment can be done using liquified formulation phosphine fumigant. The objectives of this study were to determine the concentration of liquified formulation phosphine and exposure time which will were effectively kill T. parvispinus and to evaluate the quality of cut flowers of chrysanthemums treated with phosphine fumigant. T. parvispinus was exposed to liquied formulation phosphine at 9 concentrations (0, 25, 50, 75, 100, 125, 150, 175 and 200 ppm) with 3 exposure times (1, 3, and 6 hours). Moreover, validation test of concentration nd exposure time of liquified formulation phosphine on cut flowers of chrysanthemum was conducted to evaluate the quality of chrysanthemum cut flowers of treated with phosphine fumigant. Results showed that liquified formulation of phosphine at concentration of 200 ppm and on 1 hour of exposure time completely killed T. parvispinus by 100% mortality. At 200 ppm and exposure time until 6 hours did not affect the quality of cut flowers of chrysanthemum.

Staphylinid beetle (Coleoptera) is characterized by short elytra with orange, brown, or black body color. The objective of this research was to analyse diversity of staphylinid beetles in paddy and sweet potato fields and distribution of the species in sweet potato field. Collections of beetle were done by using road sampling method in two types of agricultural fields. Distribution of beetle population were observed in the plots (1 m x 1 m) placed systematically. Seven species of staphylinids were found in this research. Five species (Paederus fuscipes Curtis, Stenus sp., Astenus sp., Hypostenus sp., and Cryptobium abdominale Motsch.) were found in paddy fields. We also found five species of staphylinid beetles (P. fuscipes, Medon sp., Stenus sp., Hypostenus prahoeensis Benick, and Philonthus sp.) in sweet potato fileds. In paddy and sweet potato fileds were dominated by P. fuscipes. Diversity of staphylinid in paddy and sweet potato fields were low. In sweet potato fields, P. fuscipes showed highest important value index (115.98%), followed by Stenus sp. (69.35%), and H. prahoeensis (5.65%). and Population distribution of P. fuscipes, Medon sp., Stenus sp., dan Philonthus sp. were uniform, while H. prahoeensis was clump.
