Anagrus nilaparvatae Pang et Wang (Hymenoptera: Mymaridae) is a major egg parasitoid of brown planthopper, Nilaparvata lugens Stal (Hemiptera: Delphacidae). The purpose of this study was to examine the egg development type, the effect of host deprivation and feeding on the reproductive performance of parasitoid. Determination of the egg development type was done by dissecting females of A. nilaparvatae upon emerging. Adult females aged 0, 1, 2, 3, 4, 5, and 6 hours were killed in the freezer. Abdominal of wasp was dissected by micro pin. Mature egg of wasp were calculated and documented. Treatment of host deprivations were conducted by feeding 10% honey solution and depriving female parasitoids of host for 3, 6, 9, 12, and 18 hours consecutively. After treatments, female parasitoids were given hosts every day until the parasitoids died. Another group of parasitoids were given with water and treated with the same lenght of deprivation period. Results showed that the A. nilaparvatae egg development type is proovigenic. The egg maturation of parasitoid has been initiated since it first emerge with 75% mature eggs of potential fecundity. In the conditions provided 10% honey solution or water as feed, reproductive performance of A. nilaparvatae decreased with increasing duration of host deprivation period, include realized fecundity, parasitization rate, and longevity of female wasp. The decline in the reproductive performance was done by host deprivation for 9 to 18 hours. Longevity of female wasps varied from one to three days, with higher and lower values consecutively for 9 and 18 hours of host deprivation period.

Pengujian Ekstrak Tumbuhan Vitex trifolia L., Acorus colomus L., dan Andropogon nardus L. terhadap Hama Pasca Panen Araecerus fasciculatus De Geer (Coleoptera: Anthribidae) pada Biji Kakao SYLVIA SJAM; MELINA MELINA; SULAEHA THAMRIN

Araecerus fasciculatus (Coleoptera: Anthribidae) is a primary pest mostly found in cocoa bean storage. Controlling A. fascuculatus is highly necessary, as this action would also reduce infestation of secondary pests. Utilization of natural materials as bait or trap is one applicable method to lessen damage and loss during storage. Vitex trifolia L., Acorus colomus L., and Andropogon nardus L are plant species that posess insecticidal properties that can be used to control post harvest pests. Materials used in this experiment are leaves of V. trifolia, rhizome of A. colomus and leaves of A. nardus. The three types of materials are blended and sieved with 300 mesh until finely broken up for make powder formulation. As much as 1 g of powder extract was taken then mixed with additional substract (water + CMC + saw dusts). The mixtures were then shaped in the form of ellipse resembling cocoa beans with approximately similar weight of 0.6 g (± 20 beans). Results show that V. trifolia and A. nardus are highly repellent (90.5 % and 94.5%) to A. fasciculatus, and crhizome of A. colomus is attractant to A. fasciculatus.

Brown planthopper (Nilaparvata lugens Stal) population from Klaten and Yogyakarta may develop into new biotype, but research on the genetic aspect of these populations is limited. Random amplified polymorphic DNA (RAPD)-PCR technique was used to identify the genetic similarity of brown planthopper population from Klaten and Yogyakarta compared to the population of nearby region. Brown planthopper were collected from paddy field in Klaten, Yogyakarta, Sukoharjo, Boyolali, Karanganyar, Sragen, and Ngawi. Five random primers, namely OPB 01, OPB 07, OPC 04, OPC 08, and OPN 15 were used to amplify the brown planthopper. The present study revealed that five random primers produced DNA band patterns clearly and comparable. However, no primer produced DNA band that could differentiate the brown planthopper population from Klaten and Yogyakarta compare to the population from nearby region. Based on dendrogram, the population from Klaten and Yogyakarta showed a genetic similarity to the nearby population from Sukoharjo, Boyolali and Sragen, except from Karanganyar and Ngawi. Intra-population genetic studies of brown planthopper from Klaten and Yogyakarta may be needed to reveal more genetic characters.

Transformation two cry genes (cryIB-cryIAa) and transformation with a single the cry1B gene under the control of a wound-inducible maize proteinase inhibitor gene (mpi) promoter were two approaches that were used to get resistant rice to the rice stemborer which may be had a durable resistance. To obtain information on the effectiveness of seven transgenic rice lines to the rice yellow stemborer S. incertulas, a test was conducted in greenhouse. The seven lines were 1). line 4.2.3 and 2) line 4.2.4 both contain fusion of two cry genes (cryIB-cryIAa); 3) line 3R9 and 4) line 3R7 lines both contain of mpi-cryIB gene; and 5) line 6.11 contains of cryIAb gene by particle bombardment, 6) line DT-cry (Azygous) that do not contain cry gene (null), and 7) DT-cry line contains cryIAb gene by Agrobacterium, and as a negative control, we used three non transgenic rice varieties i.e., Rojolele, Cilosari, and Ciherang. The result showed that transgenic rice lines, except DT-cry and DT-cry (Azygous) lines were effective to suppress damage by the insect, and showed an inhibition effect on the growth of S. incertulas, and had a high level ofresistance than non transgenic rice varieties had. There were differences on resistance value/level among transgenic rice lines. Based on the resistance value, 6.11 line was the highest followed by 4.2.4 line and 3R7 line, these lines were categorized as high resistance. Transgenic rice-4.2.3 line and 3R9 line were categorized as moderat resistance. DT-cry and DT-cry (Azygous) lines were susceptible.

The Asian corn borer, Ostrinia furnacalis (Guenée) is an important economic pest of corn and is widely distributed in the Asia-Pacific region, including Indonesia. The objective of this research is to investigate the effect of infestation levels of O. furnacalis larvae per plant on corn grain yield reductions, and to determine economic injury levels (EIL) of O. furnacalis larvae at three growth stages (V10, R1, and R2) of corn. The experiment was designed in a split-plot randomized complete block with blocks replicated three times. Differences in grain weight between the uninfested and highest infestation levels (six larvae per plant) V10, R1, and R2 were 59.81; 58.76; and 49.20 g/plant, respectively. For each additional infestation by one larvae per plant at V10, R1, dan R2, there is reduction in grain weight of 4.94%, 4.56% and 3.76% respectively. The calculation of EILs was based on the proportion of yield loss per larvae per plant on three corn growth stages with the assumption that pesticide control reduced 67% of O. furnacalis population. The lowest EIL was 0.31 larvae per plant at V10 when the cost of control reaching Rp.125,000 per ha and crop value of Rp.12,000,000 per ha. The highest EIL of 1.24 larvae per plant was found at R2 with the cost of control of Rp.250,000 per ha and crop value of Rp.8,000,000 per ha.

Whiteflies (Hemiptera: Aleyrodidae) can cause direct and indirect damages on plants, especially vegetables. There is only limited information regarding taxonomy and population dynamic of whiteflies attacking vegetables in Indonesia. This research is conducted to identify species of whitefly collected from chili pepper, tomato, and soybean, and to study their population dynamic. The information gathered from these studies will be useful to support whitefly management in the field. Based on morphology identification of the puparium collected directly from the host plants, there were four species of whitefly identified from chili pepper, tomato, and soybean in Bogor, Cianjur, and Sukabumi, i.e. Bemisia tabaci, Aleurodicus dispersus, Trialeurodes vaporariorum, and Dialeurodes sp. The presence of B. tabaci on chili pepper and tomato was associated with virus infection that causes yellowing and leaf curl disease. This population of B. tabaci tended to increase along with plant growth and generally reached the highest population when the plant was 60-70 days after planting.

Anaxipha longipennis Serville (Orthoptera: Gryllidae) is one of the generalist predator in rice habitat that has a potential as a biological control agents of rice leaf folder eggs and small insects such as rice hoppers. Females insert their eggs in plant tissue. The female’s oviposition site is important for the subsequent distribution of the cricket. Oviposition preference on 17 weeds species from rice habitat were tested in a free choice experiment in the laboratory. There was strong evidence to conclude that the cricket preferred certain plant for laying eggs. In free choice experiment nine species of weeds were preferred by A. longipennis for laying their eggs instead of rice. The preferred species were ranked as follows: rice, Monochoria vaginalis, Cyperus rotundus, C. iria, Echinochloa colonum, E. crusgalli, Eleusine indica, Fimbristylis miliacea, Imperata cylindrica, and Limnocharis flava. Whereas Ageratum conyzoides, Alternanthera sessilis, Commelina diffusa, Leersia hexandra, Leptochloa chinensis, Ludwigia adscendens, Panicum repens, and Sonchus arvensis were not preferred in free-choice test.

Infestation of pest is a major problem in the seedling and field of Jabon (Neolamarckia cadamba [Roxb.] Bosser) in Indonesia, especially in South Sumatra. Arthroschista hilaralis Walk. (Lepidoptera: Pyralidae) is one defoliator pest attacked jabon stands. Some information about the infestation of A. hilaralis are required for pest control and prevent. The objective was to study the incidence level and intensity level of A. hilaralis on jabon stands at the planting age 2 and 4 years at the 2 seasons, and analyze the effect of weather (temperature and humidity) to foliar damage caused by A. hilaralis. This experiment was conducted in six locations in South Sumatra. The plots were delineated in three area that each plot was 0.03 ha in area and contain 20 jabon trees. Observations on the incidence and intensity level of A. hilaralis were conducted every month for 16 months representing two categories of time point observation of the rainy season and dry season. The results showed that infestation of A. hilaralis on jabon stands at the planting age 2 years and the rainy season was higher than planting age 4 years and another season. The incidence level and intensity level of A. hilaralis were 74.45% and 55.21% respectively. Weather factors (e.g. temperature and humidity) thought affected the incidence level and intensity level of A. hilaralis. Temperature has negative correlation to the incidence level of A. hilaralis (r = -0.629; p = 0.009) and to the intensity level of A. hilaralis (r = -0.546; p = 0.029). Humidity has positive correlation to the incidence level of A. hilaralis (r = 0.900; p < 0.0001) and to the intensity level of A. hilaralis (r = 0.768; p = 0.0005).

The study was conducted at the laboratory and cacao plantation in Kaliwining Jember, during August to November 2008. The objective of this research was to study the effect of B. bassiana on the mortality of larvae, pupae and adults of O. smaragdina. A factorial completly randomized design was used in the laboratory experiment. Two factors were tested in the experiment, the first factor was spore concentration; the second factor was the stadia of the ants (larva, pupa and adult). The experiment was replicated, 4 (four) times. The field research used a randomized block complete design with four treatments and four replications. Results of this study showed that B. bassiana was the mortality source of larva, pupa and adult stages of O. smaragdina. A concentration of 108 spores/ml B. bassiana was effective to control larvae and pupae of O. smaragdina.

Exploration of egg parasitoids was conducted by collecting host eggs from soybean, vegetable crops, peas, corn and rice fields in West Sumatra. We found six species Telenomus distributed throughout studied locations in West Sumatera. Four species have been identified, namely T. remus Nix., T. rowani Gah., T. dignus Gah., T. dignoides Nix., whereas two others have not been identified yet because there is no appropriate identification key. The results showed that the both T. rowani Gah. and T. dignus Gah were distributed in all studied locations with different individual number, but they could be potentially be used as biocontrol agents in the future. The highest numbers of species was found in Tanah Datar and Solok with different abundance, whereas the lowest number of species were in Agam and Lima Puluh Kota.
