Impact of integrated Pest management (IPM) for cacao pod borer attack (Conopomorpha cramella (Sn.)) (Lepidoptera: Gracillariidae) dan Helopeltis sp.(Hemiptera : Miridae). Research on impact of integrated Pest management (IPM) for cacao pod borer attack (Conopomorpha cramella (Sn.)) and Helopeltis sp. had been conducted at Tumbik Melayu Village, Teluk bayur District, Berau Regency, in East Kalimantan, starting from May to September 2002. It used nested classification design. IPM practices applied in this research were pruning, balanced fertilization, weeding, field sanitation (leaf mulch), light pruning, fregment harvesting (every week), burrying of pod shell, and wrapping of young pod in week 15th. Result of the research revealed that IPM application could reduce the cacao pod borer attack reaching: a) light category before treatments from 41.29 to 15.00%; b) heavy category before treatments from 20.56 to 0 and 23.37%, compare to farmer plot. IPM implementation were able to increase percentage of healthy pod up to 18.66% compared to farmer plot. Beside it could suppers development of Helopeltis sp. population up to 24%. The dominant natural enemies were spider as many as 1.34 individuals per plant on IPM plot and 0.6 spider per plant on farmer plot (non IPM). Application of IPM practices were able to increase agronomic character: a) number of flower up to 37.22% when compare to farmer plot, and b) number of fruits until 5.56%, whereas number of young fruits decrease up 13.25%.

Cnaphalocrosis medinalis (Guenee) is a potential rice pest. The research was conducted at Subang district, used randomized block design. The big plot with 80 m x 100 m is planed by Ciherang rice variety. The big plot is divided to two plots with each size 40 m x 100 m. The first plot controlled by fipronil insecticides, but another one do not controlled us untreated plots. The untreated plot is divided to 160 small plots with size 5 m x 5 m. Observation on 30 hills per plot of randomize three plots every weeks. The result of this research show that abundance of larvae and pupae of leap folder on Ciherang variety was bimodel with two peaks. These curve indicated that leaf folder development reach two generation in one season. The relationship curve between rice plant old and leaf damage was linear curve with correlated value was 87%, but relationship curve with correlated value was 95%. The leaf folder more develop on the vegetative phase than on generative phase. The existent of larvae parasitoid, Elasmus sp is very late and abundance began of 70 days rice old with 14.8 % larvae parasitism. In the nearest harvest the larvae parasitism up to 94.4%. Amount of parasitoid is very high to reach 225 parasitoid per larvae on 70 days rice old. Analog rice growth on dry season 2002 a leaf damage level was 5-50% and effect to yield losses was 833.3 kg/ha grain dry harvested or loosing income was Rp. 1,085,550.

Parasitoids of Leafminer Fly on Potato Fields and Non-Crop Vegetation in Pangalengan Area. The damage leaves of potato and non-crop vegetation caused by leafminer fly Liriomyza huidobrensis (Blanchard) (Diptera: Agromzidae) were collected during August-October 2000 in Pangalengan area to evaluate the role of non-crop vegetation on the abundance of leafminer fly and its parasitoids. The leaves were placed into the bowls. The fly and parasitoid that emerged from the leaves were noted afterwards. The result of this survey showed that six families of plant were the host of L. huidobrensis on non-crop vegetation around the potato plantation. Those families are, Amaranthaceae, Asteraceae, Chenopodiaceae, Convolvulaceae, Malvaceae, and Solanaceae. The most abundant of non-crop vegetation found in the field was galinggang (Galinsoga Parviflora). The parasitoids that emerge from non-crop vegetation were Hemiptarsenus varicornis (Girault) (Hymenoptera: Eulophidae) and Opius sp. (Hymenoptera: Braconidae). The proportion of emerged fly were 68.5% from non-crop vegetation and 58.8% from potato, while those of parasitoids were 31.5% from non-crop vegetation and 41.2% from potato. Generally, non-crop vegetation in Pangalengan more potent as reservoar of pest than parasitoids.

Association of Arthropod on Pepper Plant Ecosystem. Ecosystem management of pepper between cover crops, Arachis pintoii, cropping system with corn, soybean and limited weeding. The objectives of this research was to find out biodiversity of arthropod on the paper ecosystem. This experiment was conducted in Lampung since May to September 2002. They are divided 5 treatments they are paper with A. pintoii, pepper with corn, pepper with soybean, pepper with limited weeding and control. The randomize blok design was used 44 kind of arthropods. The status of arthropod are: fitofag (47.73%), omnivorus (6.82%), natural enemies (34.09%) and pollination (11.36%). Distribution of each species was various at each treatment, between 26-34 species. The lowest population was found on pepper with corn, while on the highest population were occurred on the pepper with A. pintoii and control. The insect population of Acrididae, Tetrigidae, Grylidae (Orthroptera), Blattidae, Drosophillidae and Farmicidae always higher than an other insect. In this research were found 10 ordo of arthropod. Hymenoptera (Formicidae) and Araneida are dominant of arthropod and distributed at all treatment. Arthropod at pepper plant was the most abundant at pepper plan with A. pintoii. In the pepper standing plant it were only found three other, they are Hymenoptera, Araneida and Hemiptera. Beside at pepper plant and pepper standing plant, some of arthropod was found associated with A. pintoii, corn, soybean weed. Other of Orthoptera mainly grasshopper was dominating at all of plant.

Biological Activity of Six Plan Extract from Asteraceae on Spodoptera litura Fabricius (lipedoptera : Noctuidae) Larvae. Asteraceae is one of plant family that is known to have insecticidal activity to several insect pests, such as Parthenium argentatum, Crysanthemum cineariaefolium, and Agerantum houstoneanum. The aim of this study is to explore other asteraceae species in other to search for insecticidal activity to Spodoptera litura Fabricius (Lepidoptera: Noctuidae). Six species, Blumea balsamifera (leaf), Elephantopus scaber (leaf), Gynura procumbens (leaf) Artemisia vulgaris (leaf) Soncbus arvensis (leaf) and Helianthus annus (seed) were use in this study. Plant extract were obtained by meseration method using menthanol. The extract were bioassayed to the second instar larvae of S. litura to evaluate the mortality, antifeedant and growth regulation activity. Extract of B. balsamifera and E. scaber have high antifeedant activity at 5 % by reducing larval feeding 87.7% and 81.8% in no choice test, and 94.1% and 86.1% in choice test method, respectively Extract of H. annus, A. vulgaris, and E. scaber prolonged the development of larvae by 4.9, 4.1, 3.9 days, respectively. While extract of H. annus caused mortality of larvae by 86% at 5%.

Connection between Zea mays L., Ostrinia furnacalis (Lep.:Pyralidae) and Beauveria bassiana Vuill. The entomopatogen fungus, Beauveria bassiana (Balsamo), is obtained in the tissue of corn plant through submersion of seed in cinidia 1010/ml. Tissue observation showed that hifa B. bassiana appears when the plant attain the age of three weeks and when it reaches six weeks B bassiana appears in all sample plants. Hifa obtained in parenchyma tissue passively without causing illness the mother plant. The appearance of B. bassiana is remained until the 12th weeks of plant. Bio test of plan which contain the endofit of B. bassiana showed the percentage of tested insect mortality is 64%. The observation showed that the corn plant can still produce the toxin of beauverisin.

The surveys of larval parasitiod Plutella xylostella, which have been done in cabbage plantations area in Batu and Poncokusumo, Malang east Java, found other larval parasitoid biside the commonly larval parasitiod Diagdema semiclausum. The parasitoid was Teratichus howardi (Hyminoptera: Eulophidae). The percentage of parasitism was dependent of the altitude of cabbage plantation and developmental stage of crop. The percent of parasitism could reach 82% when parasitized larvae sampled in cabbage plant and the crop stage. Parasitism was also higher at the medium lowland rather than it was that the upland. T. howardi is a gregrarious larval-pupa endoparasitoid. The life cycle of T. howardi was 14-16 days. The longevity of male and female was influenced by the availability of hosts or the change of mating. The longevity of mated female which was offered some host is 14-21 days, but the longevity of mated female without hosts was 38-56 days. The mated male parasitoid lived from 1 to 4 days, but they lived 12-16 days when they were not mated. One female could lay some cluster of egg varied from 35-60 eggs cluster or from 142 to 235 eggs during the lifespan. One eggs cluster consist of ±4 eggs. The parasitoid laid one or two clusters of egg per host. Parasitoid laid eggs soon after mating at day one from eclosion until day 19th. Four to 28 Parasitoids could emerge from one host. One parasitoid was able to parasitize 17-30 larvae of P. xylostella.
