Family Curculionidae is a group of beetles (Order Coleoptera) that have an important role in different ecosystems, either as herbivores or pollinators. Land-use change, mainly from natural forest to agriculture area can have negative affect on population of curculionid beetles. The objective of this research was to study seasonal diversity, both in terms of species richness and abundance of curculionid beetles in different land-use types in Hutan Harapan landscape, Jambi. Curculionids were sampled using fogging methods. The study was conducted in four different land-use types i.e. forest, jungle rubber, rubber, and oil palm plantations in both dry (from May to September 2013) and rainy season (from November 2013 to February 2014). Four plot each of 50 m x 50 m were set up in the four land use types. We found 1762 individuals belonging to 12 subfamili and 118 species curculionid beetle. The most abundant species was found in forest (81 species) and the lowest was in the rubber plantations (20 species). The most common curculionid that were found in each land-use type were Curculioninae sp.21 (forest), Entiminae sp.06 (jungle rubber), Scolytinae sp.09 (rubber plantation) and Elaeidobius kamerunicus Faust (oil palm plantations). The highest abundance of curculionid was in oil palm plantations (853 individual) and the lowest was in rubber plantations (33 individual). Land-use type and vegetation diversity affect species richness but not abundant of curculionids. Analysis showed that different season significantly affect composition of curculionid in the forest but it has no effect in other land use types.

The objective of these studies were to observe efficiency material formulations of MsNPV and the influence to rice plantation on different locations (Indramayu (3 m above sea level), Sukabumi (400m above sea level) and Bogor (250 m above sea level) to larvae of rice army worm. This study used randomized block design with 4 treatments consisted of 3 formulation materials (talc, kaolin and gypsum) and control in five replications. Observations were done to life and death larvae on 5, 10, 15 days after inoculation and leaf damaged. Data were analysed with DMRT. Results from this study indicated that material talc formulation was more effective because all the material was dissolve as compare to material kaolin and gypsum formulations while the material were precipitated. Utilize these three material formulations on three different locations above sea level gave the same impact to the mortality army worm larvae and also to the plant damage.

Rice stem borer abundance are largely influenced by climate. This research aims to (i) develop a population dynamic model of yellow stem borer (YSB) and (ii) to assess the model's ability to predict abundance and population peak of YSB under climate change scenario SRES A1FI and B1. Modeling the YSB requires two major components: climate parameter and lower developmental threshold temperatures (To) to describe life cycle of YSB from the egg, larva, pupa, and adult stages. The research utilized DYMEX software to describe development, mortality, transfer of individuals from one to the next life stages, fecundity and reproduction of YSB. The coefficient of determination (R2) of calibration models between predictions and observations showed a strong positive correlation of 0.65. Model validation could well predict the peak population, with R2 = 0.42. The simulations showed that the trend of population peak occur at high rainfall i.e. in March to April, July to September, and November to December. The model predicted YSB population in the Sukamandi reaches 3 generations per year, while in Kuningan 2 generations per year. Simulation models under climate change scenarios SRES A1FI and B1 showed differences in the sensitivities. Trend of YSB population is increasing in the regions Kuningan and decreasing in region Sukamandi. Under changing climate, environment conditions in Kuningan become more suitable for the proliferation of YSB, allowing an increase in the number of generations per year.

The establishment of Neochetina spp. as biocontrol agent of waterhyacinth are related to the weevil’s ability to disperse and to increase their population sizes. The objective of this research was to study the distribution and abundance of Neochetina spp. at several areas in West Java and DKI Jakarta. The field research was done in several freshwater ecosystem infested by waterhyacinth, including Cibinong and Lido lakes in Bogor, irigation canal in Karawang, Muara Angke Sanctuary in North Jakarta, and Citarum Hulu river in Purwakarta, during April to August 2004. Coordinate and elevation of the research sites where N. eichhorniae and N. bruchi found were reported, while their abundances were observed by direct hand-collection technique. The results of the research showed that N. eichhorniae was widely distributed and established in most sampling sites, except in Karawang, whereas N. bruchi was not found in any sampling sites. Our observations also indicated that N. eichhorniae was distributed passively so that the weevil couldn’t colonize isolated habitats or locations.

The whitefly Bemisia tabaci (Gennadius) biotype B also known as Bemisia argentifolii (Gennadius) is a more malignant whitefly biotype in damaging plants compared to non-B biotype. Currently the whitefly B. tabaci biotype B has been reported to exist in Indonesia. Basic information such as life cycle, length of life, fecundity, and breeding ability of a whitefly is important information as a basis in preparing the whitefly control strategy. The aim of this research was to study the life cycle and demographic statistic of the B. tabaci biotype B and the non-B biotype on chili pepper. The study was conducted by observing the development of the whiteflies from eggs to adult in a growth chamber that the temperature and lighting were controlled. Observations were made on several aspects of biology and some parameters of demographic statistics. The results showed that the biotype B of B. tabaci has several different biological aspects with the non-B whitefly in chili pepper. The life cycle of the biotype B of B. tabaci and the non-B were different, 33.27 and 30.86 days respectively. The biotype B of B. tabaci had a net reproduction rate (R0) which was similar to that of the non-B biotype as well as the average of its generation. However, the intrinsic increase rate (r) of the biotype B B. tabaci was 2.5 times shorter than the non-B biotype. The biotype B of B. tabaci doubled its population (DT) 2 times faster than the non-B biotype. It is clear that the biotype B of B. tabaci potentially more dangerous than the non-B.

Polyculture system is one of techniques in pest management. In Indonesia, cotton is always intercropped with second food crops such as maize, soybean, mungbean or peanut. This research was aimed to evaluate the effect of culture system, i.e. cotton monoculture vs. cotton intercropped with soybean on the increase of species diversity of H. armigera egg parasitoids and the parasitoid contribution to mortality of H. armigera. The research was arranged in a split plot design with two main factors: three cotton varieties with three levels of trichome density (Tamcot SP 37, Kanesia 8 and LRA 5166) and the subplots were two cultivation systems (cotton monoculture and polyculture), with three replicates. Observations were made by collecting H. armigera eggs on population of first generation (45 days after planting) and second generation (75 DAP). The results showed that on cotton polyculture the egg parasitoid complex which consisted of Trichogramma spp. and Trichogrammatoidea spp. was higher than that in cotton monoculture and so was the egg parasitism level. The increase of egg parasitism was 24% in the first generation and 15% in the second generation. Parasitoid species found belonged to the genera Trichogramma and Trichogrammatoidea. In the parasitoid complex, Trichogrammatoidea armigera was dominant on the first generation and Trichogramma chilotraeae on the second. The domination succession could be as a result of the higher host-searching capacity of T. chilotraeae than that of T. armigera.

Asian corn borer, Ostrinia furnacalis Guenée, is known as an important pest of maize, Zea mays L., in both whorl and reproductive stages. Management decisions based on egg-mass density is useful because decision is made before damage occurs. Observation on O. furnacalis egg-mass distribution in maize-field was carried out in Agricultural Training, Research, and Development Station (ATRD) UGM, Yogyakarta. The number of egg-masses laid on each plant surface in maize-field was sampled in reproductive stage of corn at 52 – 58 days after planting. The spatial dispersion was analyzed using the ratio variance-to-mean (Ïƒ2/Î¼ = IÎ´), Morista's Index (IÎ³), and the negative binomial parameter (Îº-value). The results showed that horizontal and vertical distributions were aggregated distributions (Ïƒ2 > Î¼ or Ïƒ2/Î¼ > 1). In line with the increasing age of plant, the degree of clustering or aggregation likely tended to decline (the Îº-value increased, Morisita index decreased) indicating the possible departure from aggregation to randomness (Poison distribution) due to the heterogeneity of the environment, such as microclimate, preferred parts of the plants, and occurrence of natural enemies. The results concluded that the horizontal and vertical distributions of egg-masses of O. furnacalis on corn in generative phase were clustered with the degree of clustering tended to decrease by the increase of age of corn. These findings provide the bases for further study on the ecology and biology of O. furnacalis for management decision-making process.

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.
