Penggunaan mikrob untuk pengendalian penyakit dan pupuk hayati telah dikembangkan sebagai alternatif bagi pengembangan pertanian ramah lingkungan. Upaya mendapatkan mikrob tersebut terus dilakukan dengan eksplorasi mikrob dari berbagai tipe habitat ekologi untuk mendapatkan yang diinginkan. Lahan gambut diduga mengandung banyak jenis mikrob khususnya bakteri yang berpotensi sebagai agens antagonis sekaligus pupuk hayati yang bermanfaat bagi tanaman. Penelitian ini bertujuan mendapatkan galur bakteri yang berpotensi mengendalikan penyakit kresek atau hawar daun bakteri yang disebabkan oleh Xanthomonas oryzae pv. oryzae sekaligus sebagai pupuk hayati. Tahapan penelitian mencakup pengambilan sampel, isolasi bakteri asal lahan gambut serta uji potensinya sebagai agens hayati terhadap X. oryzae pv. oryzae, uji keamanan hayati, karakterisasi galur potensial, uji keefektifan bakteri sebagai agens antagonis sekaligus pupuk hayati in planta. Bakteri yang diisolasi dari tanah hutan gambut dan sawah bekas lahan gambut ialah sebanyak 134 isolat bakteri dan 40 di antaranya memiliki karakteristik morfologi yang berbeda. Sebanyak 14 galur bakteri asal tanah gambut mampu menekan perkembangan X. oryzae pv. oryzae. Karakterisasi 14 galur bakteri terhadap uji hypersensitive response, hemolisis agar-agar darah, kemampuan menambat nitrogen, siderofor yang dihasilkan, pelarut fosfat serta degradasi selulosa menghasilkan empat galur bakteri potensial. Keempat galur ini tidak berpotensi sebagai patogen terhadap tanaman maupun mamalia serta memiliki karakter sebagai pupuk hayati. Uji in planta empat galur bakteri ini menunjukkan bahwa bakteri tersebut mampu menekan keparahan penyakit hawar daun pada padi serta meningkatkan pertumbuhan padi pada fase vegetatif.

The study of host range and population dynamic of B. tabaci in red chili pepper fiel dswas conducted in Sub-district of Pakem, District of Sleman, Province of Daerah Istimewa Yogyakarta during dry season of May-October 2009. The study of host plants of B. tabaci from the red chili pepper fields revealed that there were 27 species of host plants belong to 22 genera of 13 families including crops and weeds. The host plants belong to families of Araceae, Amaranthaceae, Asteraceae, Brassicaceae, Capparidaceae, Convolvulaceae, Euphorbiaceae, Lamiaceae, Oxalidaceae, Papilionaceae, Rubiaceae, Solanaceae and Sterculiaceae. The host plant families of Asteraceae and Euphorbiaceae had the most abundant population of B. tabaci. Geminivirus-like symptoms were found in the weeds of A. conyzoides and A. boehmerioides. Population of B. tabaci adults correlated with abundance of host plant species found in the red chili pepper fields. The population of B. tabaci in red chili pepper fields was affected by natural enemy population. Population dynamic of the parasitoid Eretmocerus sp. correlated with population dynamic of the parasitized nymph of B. tabaci. Parasitoid Eretmocerus sp. was potentially good in controlling population of B. tabaci nymph in red chili pepper fields.

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.

The use of intensive and excessive insecticides on cabbage cultivations causes pest resistance, pest resurgence, environmental pollution, chemical residues, as well as decreasing the population of natural enemies and soil arthropods. Various pest control techniques have been developed to reduce the pest population, two of them are intercropping systems as part of cultural technique strategy and insecticide application. The aim of this research was to study the effect of three cabbage (Brassica oleracea) cultivation patterns and different criteria in insecticide application against soil arthropod diversity including the natural enemy population. The research was designed using split-plot experimental design. The three cultivation patterns consisted of intercropping cabbage with tomato, cabbage, and Ageratum sp. as refugia plant, and monoculture cabbage. Three criteria in insecticide application were economic threshold-based application, calendar system, and without insecticide application. In general, the results showed that cabbage monoculture cultivation and insecticide applications resulted in the lowest soil arthropod population among other treatments. Treatments of cabbage and Ageratum sp. and without insecticide application could increase the diversity of soil arthropods.

Kanzawa spider mite, Tetranychus kanzawai Kishida (Tetranychidae) is one of the most important pest mite in Indonesia. This mite is known as the pest of many crops, including cassava. Neoseiulus longispinosus Evans (Phytoseiidae) is a predatory mite commonly found on plant infested by kanzawa spider mite. This predatory mite has high potential to be developed as biological control agent of T. kanzawai. The aim of this research is to elucidate the effective density and release time of N. longispinosus to control T. kanzawai on cassava. The research was conducted in the greenhouse, using cassava of Mentega cultivar. T. kanzawai were introduced into the cassava plants two weeks after planting, with density 5 female adults/plants. N. longispinosus were introduced 1, 2, and 3 weeks after T. kanzawai introduction with predator:prey ratio of 0:5, 1:5, 2:5, dan 3:5, respectively. Population of T. kanzawai and N. longispinosus, and also plant damage were observed at 6 weeks after planting. N. longispinosus could suppress T. kanzawai population and the highest suppression occurred at the interaction between 3:5 ratio and the release time at one week after T. kanzawai infestation. There was no significant effect of N. longispinosus release at various release ratio and time on attack intensity of T. kanzawai.

Parasitoid A. lopezi dintroduksikan ke Indonesia pada 2014 untuk mengendalikan kutu putih asing invasif P. manihoti. A. lopezi berinteraksi dengan predator P. ramburi dan C. montrouzieri pada pertanaman singkong yang terserang kutu putih P. manihoti. Penelitian bertujuan untuk mengkaji pengaruh interferensi kedua predator terhadap keefektifan A. lopezi pada P. manihoti. Percobaan dilakukan di dalam laboratorium dengan menggunakan cawan petri dan kurungan serangga. Nimfa kutu putih instar-3 dipaparkan pada kedua predator selama 24 jam. Pengamatan dilakukan terhadap perilaku parasitoid dan tingkat pemangsaan predator. Kehadiran predator berpengaruh nyata terhadap penurunan masa kunjungan, masa penemuan inang, dan jumlah telur yang berhasil diletakkan oleh A. lopezi pada nimfa kutu putih. Kedua larva predator mampu memangsa kutu putih yang tidak terparasit dan yang terparasit umur 1-8 hari. Predator mampu mendikriminasi kutu putih yang terparasit umur 14 hari (mumi). Pemangsaan predator terjadi pada kutu putih yang terparasit umur 1-, 3-, dan 8- hari. Kombinasi parasitoid dengan kedua predator menunjukkan adanya interaksi antagonis. Kehadiran predator P. ramburi dan C. mountrouzieri menurunkan tingkat parasitisme A. lopezi pada P. manihoti.
