Hymenoptera parasitoids have an important role in agroecosystem because of their ability in suppressing pest population. Their presences in the field are seen as the key to agricultural ecosystem. Their presence can be influenced by the availability of non-crop vegetation. Some adult Hymenoptera parasitoids require food in the form of pollen and nectar of wild flowers to ensure effective reproduction and longevity. The objective of this research is to study Hymenoptera parasitoid communities in vegetable field and non-crop vegetation at Alahan Panjang and Kayu tanduak agricultural landscapes. Insects were sampled by two trapping techniques (farmcop and sweep net) in one lines of transect for each landscape. Total of 62species from 19 families of Hymenoptera parasitoid were collected invegetable field and non-crop vegetation at Alahan Panjang and Kayu Tanduak landscape. Landscape structure affected the species richness, diversity and evenness of Hymenoptera parasitoid invegetable field and non-crop vegetation.

Biological parameters of insect pests is very important in testing the resistance of rice plants against brown plant hopper. This research aims to study the amount and duration of stage egg, nymph, imago, and the life cycle of brown plant hopper on four varieties of rice. The methods used in research was Complete Random Design with four treatments (variety of IR 64, Batang Piaman, Cisokan, and IR 42) and eight replications. Research data were analyzed using variance analysis and continued with List Significant Different (LSD) at 5% level. The results of research showed that the number and duration of stage egg, nymph, imago, and cycle time of brown plant hopper in four rice varieties were different. Number of egg, nymph, and imago were lowest in 64 IR varieties, while the highest was IR 42 variety. Stage of eggs and nymphs were the shortest in IR 42 varieties, while the longest were IR variety 64. Imago stage was the shortest in IR 64 variety, while longest was the variety IR 42. The life cycle of brown plant hopper were shortest in IR 42 varieties, while longest was the variety IR 64. The results of this study can be concluded that the IR 64 varieties more resistant than the varieties IR 42, Cisokan, and Batang Piaman based on stage of egg, nymph, and imago.

Penyakit utama tanaman tomat yaitu busuk pangkal batang yang disebabkan oleh Sclerotium rolfsii dapat menimbulkan kerugian mencapai 80-100%. Tujuan penelitian yaitu untuk mendapatkan formula padat Bacillus cereus strain TLE1.1 yang efektif untuk pengendalian penyakit busuk pangkal batang pada tanaman tomat. Penelitian bersifat eksperimen dengan mengamati kemampuan formula padat B.cereus strain TLE1.1 dalam pengendalian penyakit busuk pangkal batang dengan Rancangan Acak Lengkap yang terdiri atas 9 perlakuan dan 3 ulangan. Perlakuan terdiri atas kombinasi bahan pembawa formula padat yang terdiri atas limbah padat ampas tebu, ampas tahu dan tongkol jagung, fungisida serta kontrol. Masing-masing formula padat B. cereus strain TLE1.1 diintroduksi pada benih dan bibit tomat. Hasil penelitian menunjukkan bahwa hampir semua formula mampu menekan penyakit busuk pangkal batang tanaman tomat. Formula terbaik dalam menurunkan penyakit busuk pangkal batang pada tanaman yaitu formula ampas tahu dan ampas tahu + tongkol jagung. Main disease of tomato plant, namely stem rot caused by Sclerotium rolfsii which can cause losses up to 80-100%. The aim of the study was to obtain a solid formula of Bacillus cereus strain TLE1.1 which was effective for controlling stem rot disease in tomato plant. This research was an experimental study to know the ability of the solid formula of B. cereus strain TLE1.1 in controlling stem rot disease which was carried out in a completely randomized design consisting of 9 treatments and 3 replications. The treatment consisted of a combination of solid formula carriers consisting of sugarcane solid waste, tofu dreg and corncob, fungicides and controls. Each solid formula of B. cereus strain TLE1.1 was introduced into tomato seeds and seedlings. The results showed that almost all of the formulas were able to suppress stem base disease of tomato plants. The best formula that reduced stem rot in plants were the tofu dreg and tofu dreg + corncob formula.
