Keanekaragaman dan Kelimpahan Musuh Alami Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) pada Pertanaman Cabai Merah di Kecamatan Pakem, Kabupaten Sleman, Daerah Istimewa Yogyakarta Hendrival Hendrival; Purnama Hidayat; Ali Nurmansyah

Research on natural enemies of Bemisia tabaci was conducted in the chili pepper fields in Sub-district of Pakem, District of Sleman, The Special Province of Yogyakarta during the dry season of May-October 2009. The aims of this research were to study the diversity and abundance of parasitoid and predator species associated with B. tabaci. Samplings of insect species were done using yellow pan trap, sweep net, direct observation of insects colonized young leaves, and collection of nymphs for B. tabaci. Measurement of insect diversity was calculated using Shannon’s index diversity and Evenness index. Nine species of insect predator were identified, i.e. Harmonia octomaculata (Fabricius), Menochilus sexmaculata (Fabricius), Scymnus sp., Micraspis inops Mulsant, Coccinella sp. (Coleoptera: Coccinellidae), Paederus fuscipes Curtis (Coleoptera: Staphylinidae), Orius sp. (Hemiptera: Anthocoridae), Linyphiidae sp.1 (Araneae), and Syrphidae sp.1 (Diptera). Eretmocerus sp. (Hymenoptera: Aphelinidae) was the only parasitoid found in the nymphs B. tabaci collected and has the potential to control B. tabaci in the red pepper fields.

Two generalist predators of brown planthopper,Metioche vittaticollis and Anaxipha longipennis (Gryllidae) have not been much studied in Indonesia. This research was conducted to study and compare the predatory ability of M. vittaticollis, A. longipennis (Gryllidae) and three coleopterans, Paederus fuscipes (Staphylinidae), Ophionea sp. (Carabidae),and Micraspis sp. (Coccinellidae) against brown planthopper (fourth and fifth instars) under laboratory condition. In total, 20 nymphs of N. lugens were exposed for 2 hour to each predator for 5 consecutive days. Prey consumptions by the predatory crickets, M. vittaticollis and A. longipennis were greater than the other predators and followed by A. longipennis, Micraspis sp., P. fuscipes, and Ophionea sp. respectively. Consumption rates of M. vittaticolis and A. longipenis were also higher than other predators. Micraspis sp was more active on predation in the morning,while M. vittaticollis, A. longipennis, P. fuscipes, and Ophionea sp. were more active both in the morning and the night but not in the afternoon. However, all five species of predators were not so active in preying during the afternoon. In conclusion, a major effort should be extended to conserve these predatory crickets especially M. vittaticollis and A. longipennis.

On early development of intensive cotton program, insect pests were considered as an important aspect in cotton cultivation, so that it needed to be scheduled sprays. The frequency of sprays was 7 times used 12L of chemical insecticides per hectare per season. Development of cotton IPM was emphasized on non-chemical control methods through optimally utilize natural enemies of the cotton main pests (Amrasca biguttulla (Ishida)Helicoverpa armigera (Hübner)). Conservation of parasitoids and predators by providing the environment that support their population development is an act of supporting the natural enemies as an effective biotic mortality factor of the insect pests. The conservation could be done by improving the plant matter and cultivation techniques that include the use of resistant variety to leafhopper, intercropping cotton with secondary food plants, mulch utilization, using action threshold that considered the presence of natural enemies, and application of botanical insecticides, if needed. Conservation of parasitoids and predators in cotton IPM could control the insect pests without any insecticide spray in obtaining the production of cotton seed. As such, the use of IPM method would increase farmers’ income.

Control of whitefly (Bemisia tabaci (Gennadius)) is the starting point in suppressing the CMMV disease (cowpea mild mottle virus). This study aims to determine the influence of applications BPMC (500 g a.i./l) against B. tabaci populations and disease incidence of CMMV on soybean plants. Research was conducted in the field with randomized complete block design consisting of 5 treatments i.e. five concentration levels: 0.75, 1.50,2.25, and 3.00 ml/l including control (untreated) with 5 replications. The results showed that BPMC is effective in suppressing the adult population of B. tabaci and disease incidence of CMMV.

Preferensi dan Kecocokan Inang Pentalonia nigronervosa Coquerel (Hemiptera: Aphididae) terhadap Berbagai Varietas Pisang Suparman Suparman; Nurhayati Nurhayati; Anita Setyawaty

Pentalonia nigronervosa Coquerel (Hemiptera: Aphididae) is the only known vector of banana bunchy top virus (BBTV). The objective of this research was to study the preference and suitability of banana aphid P. nigronervosa to various banana genotypes. Survey conducted at Talang Betutu, South Sumatra indicates the existence of different preferences of the P. nigronervosa toward different varieties in the field. Host suitability test was conducted using 13 banana varieties that were invested with P. nigronervosa from taro plants. Preference test was conducted using a 200 cm x 200 cm x 150 cm mesh cage that were used to house 13 banana genotypes that were invested with P. nigronerosa. The numbers of aphids on different banana genotypes were observed. Result of the study showed that “kepok” genotype was more suitable for the growth of P. nigronervosa compared to other genotypes. The suitability was shown by higher population, faster population growth, lower mortality and the higher proportion of alate adults. Banana kepok infested with 20 aphids at the beginning of the test reached 324 individuals within 24 days with population growth rate of 8.27% per day, and produced 1.9% of alate imagoes appeared 6 days after infestation. Host preference test using the same genotypes suggested that the aphid prefer banana kepok more than to any other genotypes.

Thrips parvispinus Karny (Thysanoptera: Thripidae) pada Tanaman Cabai: Perbedaan Karakter Morfologi pada Tiga Ketinggian Tempat Dewi Sartiami; Magdalena Magdalena; Ali Nurmansyah

One of the important pests on chilli plants is Thrips parvispinus Karny (Thysanoptera: Thripidae). The presence of the pest is detected ranging from lowlands to highlands. This study was aimed to find out the morphological diversity of T. parvispinus at three different altitudes which include Cirebon (< 30 m asl), Bogor (300 - 400 m asl), and Cianjur (> 1200 m asl). At each level of altitude, it was collected 60 female adults of the thrips and then they were preserved into microscope preparations using Hoyer medium. The observed morphological characters of T. parvispinus were the length of body, the width of head, the width of thorax, the length of wing, and the color of body. The difference in morphological characters of the thrips in all three levels of altitude were analyzed using analysis of variance and Duncan's multiple range test. The correlation between altitude and body color was analyzed using chi- square test. Results showed that the body length, thoracic width, and wing length of the highland thrips were longer than those of the mid and lowland thrips. The three morphological characters showed significant differences between the mid and lowlands and the highlands, except for the character of head width. Changes in the color of the head, thorax, and abdomen were correlated to the level of the altitude.
