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.

Green leafhopper-resistant variety is one of rice tungro virus disease control measure. Green leafhopper (GLH), Nephotettix virescens is the most efficient vector of tungro. Among 7 sources of resistant gene to GLH 4 genes have been employed to breed resistant variety. Efficiency variant of GLH as indicated by their efficiency to transfer tungro virus was identified by inoculation test. GLH colonies were collected from tungro endemic areas in Java, Bali, West Nusa and South Sulawesi. Efficiency variant of GLH colony was characterized by their ability to transfer tungro virus to GLH-resistant variety with various source of resistant genes. Sources of tungro inoculum were obtained in Bogor. The results of the test showed that there was a variation in the ability of GLH colonies to tranfer tungro to various GLH-resistant variety, thus indicate there was a variant in GLH colony. The ability of GLH colonies to transfer virus ranked from high to low, were West Nusa Tenggara, Bali, East Java , South Sulawesi, D.I. Yogyakarta, West Java and Central Java. On the other hand GLH-resistant variety ranked from resistant to susceptible were varieties with resistant genes group glh4, Glh6, Glh1 and Glh5. Five variants colonies of GLH were successfully identified which named as colony 0050, 0000, 1050, 1650 and 1654. Biotype 0000 has the lowest ability to transfer virus but biotype 1654 efficiently transfer virus to all of GLH-resistant variety groups.

Pink bollworm, P. gossypiella, is a main pest of cotton that causes boll damage up to 70%. Recommended IPM has not effectively control this pest. The use of parasitoids of this pest is one of strategy to manage this pest population as using chemical control is expensive and caused secondary pest. This research objective is to study some biological aspects of pink bollworm parasitoids by doing exploration of the parasitoids in cotton growing areas and testing the potential candidates as biocontrol agents. The activity was conducted from April - December 2001. The research was conducted in two steps: survey and laboratory tests. The survey was conducted in East Java (Asembagus and Lamongan), Central Java (Brebes) and South Sulawesi (Bone) by collecting pink bollworm eggs and identifying the emerged parasitoids. Laboratory tests were done in Biological Control Laboratory of ITFCRI, Malang, consists of reproductive performance aspects. We found two and five species of egg and larval parasitoids, respectively. Parasitism level of egg was 81% by Tichogrammatoidea spp. and that of larva was 24% by Apanteles sp. These two parasitoids are predominant and found in all cotton growing areas. Tichogrammatoidea spp. have opportunity to be used as biocontrol agent in release program, while Apanteles sp. would have valuable role in conservation approach.

Pengaruh biosin dan ekstrak cente terhadap perkembangan Aphis glycines (Homoptera : Aphididae) Harnoto Harnoto; Dodin Koswanudin; Asep Nugraha Ardiwinata

A study was conducted at Engineering of protein and Immunology. Division, Research Institute for Agricultural Biotechnology and Genetic Resources Bogor during 2000, to determine the effect of Biosin and Lantana camara seed extracts on development of Aphis glycines A. completely randomized design was used with four replications. Treatment consisted of three concentrations of Biosin and two concentrations of L camara seed extracts and untreated (control). Thirty days old soybean plant in plastic pots were applied according to its treatments. Biosin and L camara seed extracts were used as foliar spray. Volume of spray solution was 7.5 ml/pot. Half an hour after application, soybean plants were infested by 20 third instar A. glycines each pot. The result showed that Biosin and L. camara seed extracts decreased the development of A. glycines populations, especially Biosin and L camara seed extracts 0.4%.

Berry sucker insect pest, Dasynus piperis china (coreidae; Hemiptera) is one of the major insect pest on pepper. D. piperis to attack fruit of pepper with suck of fruit liquid and the final effect is empty to fruit and damaged. To find out of the level of damage and destruction caused by D. piperis have been done at 6 districts of Bangka Island namely Mendo Barat, Sungai Selan, Sungai Liat, Belinyu, Koba and Toboali since January to December 2002. For each district were observed 5 farmers field of estate crops. Every farmer field were observed tens plant of pepper in connection with fluctuation population and level of fruit damage. The observation have been done on the flower season of pepper, after flower season and after harvest. The result showed that fluctuation population and infested level of D. piperis at each observation almost the same, while among district were variated. The highest infestation was found in Sungai Selan, followed by Belinyu, and Mendo Barat namely 36.82;32.03 and 29.48 % respectively. The infestation level on Sungai Liat, Toboali and Koba were low namely 14;79.58 and 20.98 % respectively. The level of damage in Mendo Barat was highest than an other location namely 8.66; 8.07; 6.67; 5.71;4.89 and 3.09 % in Mendo Barat, Sungai Selan, Belinyu, Koba, Toboali and Sungai Liat respectively.

Field and laboratory studies were conducted on potatoes in pangalengan during April until October 2001, with the objectives to determine the daily activity pattern of the predatory fly Coenosia humilis Meigen (Diptera: Muscidae), to study the behavior of predator as well as level predation, and to evaluate effects of two cultural practices on population of flies. Our research revealed. that C. humilis were more active during morning and afternoon. Predatory flies attacked by capturing the flying preys, and then sucked preys body content. The preys were generally small insects. About 60% of the preys were found to be agromyzed files, Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae). In laboratory each predator consumed 23.5 leafminer flies per day. Insecticide application significantly suppressed the predator and at the same time promoted the leafminer population.

Karakteristik morfologi dan fisiologi beberapa isolat lokal bakteri simbiose nematoda entomopatogen kompleks serta uji virulensi pada larva Plutella xylostella Mardianto Harahap; Didik Sulistyanto

Local isolates of entomopathogenic nematodes are symbiotically associated with bacteria of the genus Xenorhabdus or Photorhabdus. Symbiont bacteria isolated from local isolates of entomopathogenic nematode (Pujon, Cemoro Lawang and X. nematophilus) were identical with Xenorhabdus spp and isolate of Ngadas was identical with Photorhabdus luminescens. Some isolates, such as Xenorhabdus (isolate of Pujon) and P. luminescens (isolate of Ngadas) has a high virulence when the bacteria was injected into insect haemocoel. High virulence was indicated by Xenorhabdus nematophilus when it was applied orally.
