The occurrence of ants in agricultural habitat is related to the availability of food resources as well as environmental condition for its nesting site. As predator, ants play an important role on controlling pest population in agricultural habitat. The objective of this research was to study the diversity of ants in pepper plantation. The research outcome can be used as basic information for cultivation management of pepper. Ecological observation was conducted in four regencies in Lampung Province with two selected plots on each regency. On each plot, ants were sampled using pitfall traps. In total, 28 ant species were recorded from pepper field in four regencies. Two species i.e. Anoplolepis gracilipes and Solenopsis geminataare well-known as tramp and invasive species. There is significantly different of ant species composition among regencies. The occurrence of ants in pepper plantationis probably affected by habitat condition surrounding pepper plantation and precipitation.

Blood diseases caused by Ralstonia solancearum Phylotype IV is a major cause of production loss of banana in Indonesia, particularly for areas in West Sumatera. Currently there is a lack of information on blood diseases. The objective of this study was to obtain data of insect diversity and its potential as a dissemination agent of R. solanacearum Phylotype IV in West Sumatera. This research was conducted with a purposive sampling method in the Tabek Panjang highlands, District of Baso, Agam Regency and Pasar Usang lowland, district of Batang Anai, Pariaman Regency, West Sumatera. The results showed that banana plants infected by R. solanacearum Phylotype IV have a high diversity of flower-visiting insects. The diversity of insects in the lowlands is higher than that in highland and mainly are dominated by Trigona spp. (Hymenoptera: Apidae), Drosophila sp. (Diptera: Drosophilidae). To test the potential of both insect as vector of the blood diseases, isolated and identification of the bacteria using triphenyl tetrazolium medium chlorid (TTC) was used. Result showed that bacteria isolated from both insect are R. solanacearum hence providing evidence of the insect as vector of the blood diseases. Both insects have the potential to be vector of R. solanacearum Phylotype IV in West Sumatera. The identification of the bacteria that causes the disease. The identification of bacteria that is spread by flower visitors insects are R.solanacearum Phylotipe IV.

Pollination within syconium (figs) of the fig trees (Ficus spp.) depends on female fig wasps that belong to Family Agaonidae (Order Hymenoptera); on the other hand, the female wasps can only lay eggs inside the fig flowers in which the offspring later develop. Several species of non-pollinating wasps are also known to develop within the figs. A research to investigate the fig wasps community (pollinator and non-pollinator) and their impact on the figs has been conducted on fig tree species of Ficus racemosa L. in Aceh Province. Fig fruits of F. racemosa were sampled when they were on receptive stage (B-phase) and when the figs were almost mature (D-phase) on the same trees. The young figs were dissected to observe the pollinating wasps (foundresses), while the mature figs were incubated until the new generation of fig wasps emerged from the figs. The wasps then were identified and counted. Observations on B-phase figs showed that the pollinating wasps of F. racemosa was Ceratosolen fuscicep (Mayr) (Hymenoptera: Agaonidae) which entered the fig through ostiole. The fig wasps community that emerged from D-phase figs consisted of pollinating and non-pollinating fig wasps, Platyneura fusca dan P. agraensis (Hymenoptera: Agaonidaed) were the competitors of pollinating wasps in taking the ovules for their development, while Apocrypta sp. (Hymenoptera: Pteromalidae) was a parasitoid of the pollinator. However, in this research there was no evident that the presence of these non-pollinating wasps significantlyt affect the number of pollinating wasps and seeds of F. racemosa.

Cut flower of chrysanthemum has high aesthetic and economic values. Export volume of chrysanthemums from Indonesia are lower than other countries, due to the impact of insect pest. Insect pests, Aphis gossypii Glover and Macrosiphoniella sanborni Gillette are currently associated with cut flowers especially chrysanthemum. One control measures usually taken in quarantine is fumigation. Alternative fumigant, liquified phosphine formulations may potentially be applied for quarantine treatment. The objectives of this study were to determine the concentration and exposure time of liquified phosphine against these species and to evaluate the effect of fumigant on the physical quality of cut flowers. The experiment was conducted in four steps: (1) identification and mass rearing of A. gossypii and M. sanborni; (2) preliminary tests on adult and third instar nymphs; (3) determination of liquified phosphine with various concentration and exposure time against adult and third instar nymphs of A. gosspypii and M. sanborni and; (4) validation test of effective concentration of fumigant and exposure time and the effect on quality of cut flowers. The results of study showed concentration of fumigant causing 100% mortality A. gossypii and M. sanborni ere 500 ppm and 700 ppm, respectively with exposure time 12 hours. Concentrations of 700 ppm and exposure time up to 18 hours did not cause negative impact to the quality of chrysanthemum cut flowers.

The effectiveness of Neochetina eichhorniae as a biocontrol agent of waterhyacinth was evaluated in West Java and DKI Jakarta. The objective of this research was to study the implication of the existence of N. eichhorniae on waterhyacinth. Research was conducted in several freshwater ecosystem infested by waterhyacinth and N. eichhorniae, including Cibinong and Lido lakes (Bogor District), Muara Angke Sanctuary (North Jakarta), and Citarum Hulu river (Purwakarta District), conducted during April to August 2004. The impact of N. eichhorniae on waterhyacinth was evaluated by leaf damage intensity and growth parameter of the plant. Results showed that there was no correlation between waterhyacinth and the occurrence of the N. eichhorniae. The population of N. eichhorniae adults was significantly low in any locations studied. Thus, the existence of the biocontrol agent can not result in decreasing of waterhyacinth population.

Plants produce volatiles as communication cues intra- or inter- species. Infested plants by herbivores will produce volatiles as indirect defense mechanism that attracts natural enemies of herbivores. Analysis of volatiles compounds produced by rice plant as result of infested brown plant hopper (BPH), Nilaparvata lugens Stâl, was done to identify compounds in the volatiles that potentially can be used as attractant for egg parasitoids of BPH, Anagrus nilaparvatae (Pang et Wang) (Hymenoptera: Mymaridae). This research was an early stage to develop formulation of parasitoid attractant. The research activities include volatiles extraction of infested rice stem by BPH eggs using acetone, n-hexane as the extraction solvents; analyses of volatile compounds with GC-MS; and bioassay of parasitoid orientation behavior to the volatiles using olfactometer methods. Extraction methods applied were maceration and continuous extraction followed by concentration. Bioassay on the parasitoid orientation behavior was done by using Y-tube olfactometer and every lot of bioassay using 30 parasitoid females with 3 replicates. The results showed that the volatile compounds of extract of infested rice stem by BPH eggs comprise of 16 components. The highest proportion of the components extracted with acetone is 2-Pentanone, 4-hydroxy-4-methyl (19,9%), while those with n-hexane is Hexanedioic acid, dioctyl ester (65%). A. nilaparvatae showed positive response to the volatiles extracted from infested rice plant by N. lugens eggs. Therefore, the volatiles can be used as an attractant for the egg A. nilaparvatae to support rice pest management.

Predatory arthropods inhabiting paddy rice ecosystems in Cianjur District, West Java. Predatory arthropods were surveyed in Cianjur District, West Java from July to November 1997, with objectives to observe the species of predatory arthropods inhabiting the ecosystems. Canopy-inhabiting and soil-dwelling arthropods were sampled using D-vac and pitfall traps, respectively. Results indicated that insecta and Arachnida were the most abundant predators in the ecosystem, with the total of 142 species. Predatory insects were dominated by Carabidae (27 species), and Staphylinidae (13 species) and spiders were dominated by Therididae (9 species), and Lycosidae (8 species). Thus, predatory-arthropods inhabiting the sawah ecosystems were very diverse.

Black ants, Dolichoderus thoracicus (Smith) (Hymenoptera: Formicidae) is one of the biological agents that can be used to control the cocoa pod borer Conopomorpha cramerella and Helopeltis sp. To effectively prevent C. cramerella infestation, high population of black ants are required. Population growth of black ants in three types of permanent nests and non permanent nest were observed during 3 months. Every month, five nests of each type were taken at random and then all stadia were calculated. The permanent nests will support ant population for some years and the black ant population per nest is higher when compared to nest made of dried cocoa leaves only. Permanent nests are made of 75 pieces of dried cocoa leaves which are placed in plastic bags with ventilation holes. In the longer term permanent black ant nests are more cost effective then ant nests which have been made from only dried leaves because frequent replacement is not required. Permanent ant nests will also ensure a stable black ant population is maintained.

Cucumber is a monoceous plant and require pollinators for pollination process. Diversity and foraging activity of pollinators affect the effectiveness of pollination, which can improve the yields. The aim of this research were to study the diversity, foraging behavior, and effectiveness of insect pollinators on cucumber plants. Scan sampling was used as on of the methodology for observing pollinator diversity, while foraging behavior was observed using focal sampling. Pollination effectiveness were measured based on the number of fruit set of opened and caged plants. Fifteen species were found as pollinator of cucumber, i.e., Xylocopa confusa Pérez, Xylocopa latipes (Drury), Xylocopa caerulea Fabricius, Ceratina bryanti Cockerell, Amegilla burnensis Lieftinck, Nomia quadridentata Bingham, Nomia sp., Megachile unbripennis Smith, Megachile aff. disjuncta Fabricius, Megachile conjuncta Smith, Campsomeris javana Lepeletier, Syrphus sp., Parasyrphus sp., Eurema hecabe Linnaeus, and Vanessa cardui Linnaeus. The longest visit on cucumber flower pattern was by Syrphus sp. (50.71 seconds/flower), while the shortest visit was by X. confusa (4.78 seconds/flower). Pollination by insects increase 100% production as measured by healthy fruit per plant. Pollination also increase 77.61% of seeds number per fruit and 28.57% of seed weight.
