The study aims to determine the presence of pests and natural enemies on soybean plants and to study the effect of insecticides on the diversity. Methods for observation of insects was done by using different type of traps i.e. yellow pan trap, pitfall trap, light trap, sweeping net and direct observation (visual). The presence of pests and natural enemies of soybean plants on plots without insecticide was lower than on the plots that was treated with insecticide. Composition of the population of pests found in soybean plots that were not treated with insecticide were dominated by Aphis sp. followed by Phaedonia inclusa, Riptortus linearis, Nezara viridula and Ophiomyia phaseoli. Composition of the population of natural enemies (predators) found in soybean cropps that were not treated with insecticide was family Coccinellidae followed by Syrphidae, Chrysopidae, Mantidae and Oxyopidae. The highest composition of natural enemies (parasites) found in treated and untreated soybean plots were family Braconidae then followed by family Ichneumonidae.

Aphids (Hemiptera: Aphididae) are considered as one the most important pest in the world. Some species of aphids were reported as serious pests and plant virus vectors, especially on horticultural crops. Weeds in the agricultural area can serve as an alternative hosts for some aphids which are plant pests or plant virus vectors. The objective of this research was to identify aphid species of weeds in the agricultural production area in West Java and to provide the identification key. Aphids collection was done on the weeds in the agricultural fields in 9 districts of West Java. Aphids were collected from 13 species (5 families) of weeds. The identification of aphid was peformed based on the adult specimens. The research manased to come up with 12 species of aphid on weeds. Three of the 12 collected species were Epameibaphis frigidae (Oestlund), Metopolophium dirhodum (Walker), and Pseudaphis sijui (Eastop) has never been reported in West Java. Six species were known as vectors of plant viruses in agricultural crops. The most commonly found aphid species was Schizaphis graminum (Rondani) in the yard grass (Eleusine indica).

The research was conducted at Laboratory of Insect Physiology and Toxicology of Plant Protection Department of Bogor Agricultural University from May to July 2008. Leaves, twigs, barks, and roots of Eurycoma longifolia (Pasak bumi) were extracted with hexane, ethyl acetate, and methanol solvens. The extraction was used single method and level method. Insecticidal activity of each extract has been examined in laboratory to major cabbage pests Crocidolomia pavonana using leaf residual method. Methanol root extract from single method and level method caused 100 and 75.5% mortality of insect test respectively. Hexane and ethyl acetate extracts of leaves, twigs, and barks have low insecticidal activity. The antifeedant effect worked at insect test and varied depends on concentration level. Antifeedant effect also contributed to mortality of larvae along with toxicity of each extract.

Bemisia tabaci (Gennadius) is an important pest on horticultural crops that can also become a vector of Geminivirus that transmit the yellow curl disease. B. tabaci can also attack weeds that grow around the field such as Ageratum conyzoides or goatweed. The objective of this research was to study the life cycle, life time, fecundity, and reproduction rate of B. tabaci on chili pepper and goatweed. The experiment was conducted by observing the development of 50 eggs into adulthood. All 50 eggs were put on one plant and repeated 3 times. The plants were grown at temperatures 25 °C and 29 °C inside growth chamber (L : D = 12 : 12). The result of this experiments showed that at both temperatures of 25 °C and 29 °C, reproductive rate (R0), intrinsic rate of increase (r) and fecundity of B. tabaci were higher on goatweed than chili pepper. This implies that the existence of goatweed around chili pepper in the field can serve as a good alternative host for B. tabaci, hereby supporting the pest population even further.

The objective of study was to investigate the effectiveness of Beauveria bassiana isolate cultured in half-ripe rice media against third-instar larvae of Plutella xylostella. The research used 10 isolates consisted of 4 isolates that were originnally collected from Pagaralam i.e. PD1 (isolated from P. xylostella cadaver), PD2, PD8, PD9B (from Crysodeixis chalcites cadaver), and 6 isolates from other areas as comparison, i.e. CCW3 (from Crysodeixis chalcites cadaver), BBL (from Hypothenemus hampei cadaver), CH (from Conomorpha cramerella cadaver), CPJW (from H. hampei cadavi), WC (from Nilaparvata lugens cadaver), and WSJT (from Leptocorixa acuta cadaver). The parameters that were measured were mortality of larvae, time of death and behaviour of larvae after application. Result of the test showed that B. bassiana isolated from L. acuta (WSJT isolate) caused the highest mortality i.e. 73.34 %, with the highest spore density 5.6x107 spore ml-1 (in half-rice media) and 3.0x107 spore ml-1 (GYA media). The lowest LT50 was 19.27 hours, and was obtained from the application of PD9B. After application of B. bassiana, the behaviour of larvae was slightly change from a healthy one to less in consuming of food and then die.

Research on the effect of host larval stage on survivorship of the parasitoid E. argenteopilosus was conducted under laboratory conditions. Survivorship was studied by using S. litura larval with different stage (1st, 2nd, 3rd, and 4th instars). Result of the research indicated that development rate of the parasitoid E. argenteopilosus is faster when reared on 3rd instar larvae. The higher the level of host-instar larvae, shorter time was needed to complete the parasitoid’s life cycle. Only 4.67% of the larvae completed its development to pupal stage, and only 1% reached adulthood, with males being the dominant of the emerging adults.

Presence of insects in agricultural habitat is affected by several factors such as natural habitat. The objective of this research was to study the effect of natural habitat on diversity and abundance of flower-visiting insects in cucumber fields. Ecological observation was conducted in 12 cucumbers fields located in regencies of Bogor, Cianjur, and Sukabumi, West Java. Cucumber fields were categorized in two different distant form natural habitat i.e. near natural habitat (less than 200 m) and far from natural habitats (more than 1000 m). The observations of flower-visiting insects in cucumber fields were conducted by counting the number of flower-visiting insects that perched within 100 flowers in four different transects. The result showed that the presence of natural habitat affected species richness but not the abundance of flower-visiting insects in cucumber field. The dominant species of flower-visiting insects in cucumber fields were Aphis sp., Tapinoma sp. and Thrips parvispinus Karny, while the most dominant pollinator was Apis cerana Fabricius. The distance of natural habitat from farmland affected the presence of flower-visiting insects especially pollinator insects that provide important services on enhancing crop yield.

Cylas formicarius (Fabricus) (Coleoptera: Curculionidae) is one of the major pest on sweetpotato which can cause yield lost up to 100%. The objective of this study was to obtain the effective and efficiency control technique of sweetpotato weevils. The research was conducted on June–October 2014 at Muneng Research Station, Probolinggo, East Java, using randomized block design, five treatments and three replicates. The treatments consisted of immersion of sweetpotato cuttings in the suspension of conidia Beauveria bassiana (Bals.) Vuill. for 30 minutes before planting; application of suspension of conidia B. bassiana on soil at 2, 4, 6, 8, 10, and 12 weeks after sowing (WAS); immersion of sweetpotato cuttings in the suspension of conidia B. bassiana for 30 minutes before planting combined with application of suspension of conidia B. bassiana on soil at 2, 4, 6, 8, 10, and 12 WAS; application of chemical insecticide every week; and control. Analysis of variance showed that the application of various control technique significantly lowered the population of larvae and imago of C. formicarius and the level of tuber damage. The population level found on all treatments ranged from 1–4 eggs/plant, 1–19 larvae/plant, 0–0.2 pupae/plant and 0–4 imago/plant. The weight of tuber was 571–700 g/plant with the level of damage 6–53%. Low level of damage was found in the aplication of suspension of conidia B. bassiana on soil at 2, 4, 6, 8, 10, and 12 WAS which were 6%. Application of suspension of conidia B. bassiana on soil at 2, 4, 6, 8, 10, and 12 WAS can suppress the population of C. formicarius on tuber and reduce the level of damage up to 48%.

Stalk eye flies (Diptera: Diopsidae) is an insect family which has unique eye morphology. Their eyes are in the distal end of a long stalk. The information of species and their habitats is still very limited in Indonesia. Therefore, the objectives of this research were studying species diversity, habitat, and distribution areas of stalk eye flies in soroundings in Bogor. The sample sites are classified into three areas; lowland, middle, and upland. The flies ware taken with two methods: net sweeping and direct capture, then parts of the body were measured. The observation of stalk eye flies activity and behavior was done in the morning, midday, and afternoon. The result of observation indicated that stalk eye flies were found almost in all areas, from lowland to upland. On 15 survey locations, stalk eye flies were found in 10 locations with the same habitat. The species are Cyrtodiopsis dalmanni and Teleopsis sp.. C. dalmanni was found in 5 locations, and Teleopsis sp. in 9 locations. The observation result of stalk eye flies activity and behavior indicated that the number of stalk eye flies which captured in three period of time were not obviously different. Result from measuring stalk eye flies bodyparts indicated that the average size of male and female flies was not obviously different, except the male stalk is longer than female. In addition, C. dalmanni stalks are longer than Teleopsis sp. stalks.

Aphis craccivora is one of the important pests on yard long bean. It causes direct damage and also has an indirect effect as insect vector of the Bean common mosaic virus (BCMV). The research was done to test the effectiveness of chitosan in suppressing aphid population growth, feeding preference and its ability in transmiting BCMV. Chitosan with concentration ranging of 0.1–1.0% were applied on leaves using spraying method at 1 day before BCMV transmission. BCMV was transmitted by using 3 individuals of viruliferous aphids on each plant. Results show that chitosan treatments on leaves or plants significantly suppressed the population and feeding preferences of A. craccivora. Further, treated plants showed lower disease incidence, severity and BCMV titre significantly compared with untreated control plants. The positive effects of chitosan in suppressing population growth as feeding preferences and BCMV transmission might be due to the anti-feedant effect of chitosan on A. craccivora. Based on the result, chitosan at concentration 0.9% is the most effective concentration in suppressing BCMV and its vector A. craccivora.
