Eradicating rice pests in South Kualuh is difficult to do optimally, because most farmers do not understand the types of pests that attack their rice plants. The objective of this study was to obtain information about the type of pest insects in rice plants and to find out the diversity index of insect pests in rice plants. This research was conducted using trap method and collection of insects was done using a insect net. Observation data was analised using Shanon Wiener (H) diversity / diversity index. The result showed 13 types of pest insects which belongs to 10 families. That is Tettigonia sp.(Linnaeus, 1758), Sogatella furcifera (Horváth, 1899), Nephotettix virescens (Distant, 1908), Cofana spectra (Distant, 1908), Atractomorpha crenulata (Fabricius, 1793), Erotides sp.(Laporte, 1836), Leptocorisa acuta (Thunberg, 1783), Aulacophora indica (Gmelin, 1790), Chrysochus cobaltinus (LeConte, 1857), Silba capsicarum (McAlpine, 1956), Hercostomus germanus (Wiedemann, 1817), Cnaphalocrosis medinalis (Guenée, 1854), Scirpophaga incertulas (Walker, 1863). The diversity index of rice pest insects was categorized as moderate with a value of 2,35 and a dominance index of 0,108. This value indicates that the distribution of species is evenly distributed so that no insect species dominates in the area.

<p>Brown planthopper (<em>Nilaparvata lugens</em> (Stål)) is one of the major rice insect pests that is known to cause high loss of rice production. One of the strategies to control this pest is by using resistant rice varieties. The aim of this research was to study the resistance of IPB 3S variety to BPH by measuring BPH fecundity, sex ratio, feeding activity as well as population increase compared to Ciherang variety against brown planthopper (<em>N. lugens</em>). Fecundity test used a pair of BPH adult infested on 21 days after planting (DAP) of rice plants. Eggs laid in rice stalks and the rest of eggs in the ovary were counted. In order to know the change of sex ratio, a pair of BPH adults was infested on 30 DAP rice plants and allowed to lay eggs. The calculation of sex ratio was conducted at adult stage of BPH by segregation between male and female adults. Feeding activity of BPH was evaluated using ninhydrin and analyzed qualitatively using spectrophotometer. Ten fourth instar nymphs of BPH was infested on 30 DAP old of rice seedlings. Honeydew secreted by BPH was collected to filter paper sprayed with ninhydrin. Population increased test was conducted by infesting five pairs of BPH adults on 35 DAP old rice plants. Observations was conducted on nymph and adult stages. Each test was replicated 10 times. In general, IPB 3S is slightly resistant to BPH, compared to Ciherang variety. The feeding activity of BPH is higher in Ciherang compared to IPB3S. However, the fecundity and population increased of BPH in Ciherang is similar to IPB3S.</p>

Baduy people have local wisdom about the use of plants, among others, as ingredients to prevent the presence of rice pests (Oryza sativa L.). the importance of these pest-preventing plants to produce allelopathy in order to prevent rice pests (Oryza sativa L.). To find out what plants are used by Baduy people, this research is necessary. Exploration of pest control plants is carried out using the PEA (Participatory Ethnobotanical Appraisal) approach, besides that it also uses survey methods and open interview techniques. The results of the survey were 21 non-key informants and 5 key-informants from the Outer Baduy community and 12 non-key informants and 1 key informant from the Inner Baduy community, 35 species from 22 plant families were used in all rituals to prevent the presence of rice pests. . Plants that have similarities in usage by the Outer Baduy and Inner Baduy are Bamboo Wuluh leaves (Schyzostachyum iraten), Noni leaves (Morinda citrifolia), Bemban (Donax canniformis), Walang leaves (Achasma walang Val.) And Langge leaves (Homalomena cordata) . The percentages of plant organs used to prevent the presence of rice pests are leaves (77%), stems (17%) and fruit (6%). The method of processing plants as raw material for rice pest prevention ingredients is to cut them in small volumes / chop (39.74%), pound (52.56%), ferment (3.85%) and burn (3.85%). Baduy rituals in preventing the presence of rice pests include 5 types namely Ngubaran Samara Pungpuhunan ("Treatment" of Main Plants), Ngubaran Cangkudu ("Treatment" of Noni), Ngubaran Bangban ("Treatment" of Bemban / Donax canniformis), Fumigation, and Leuit Susumpingan (Lumbung offerings)

Nilaparvata Lugens Stål

Rice (Oryza sativa L.) is the most important staple food in the world including Asia and Pacific. Millions of people around the world depend on rice due to the high calories and economic returns it provides. More than 100 species of insects including 20 economic pests are capable of causing notable damage to rice plants. Insect pests continue to pose threat to rice farming since rice plants serve as their host plants. Pests are major constraints to rice production and coexist with rice growth. Information on pest economic importance, description, biology, distribution, economic threshold level, population dynamics, monitoring and forecasting is a prerequisite. This review is focused on brown planthopper (Nilaparvata lugens Stål) which is an important economic rice pest that are prevalent in tropical rice growing regions. Brown planthopper (BPH) is a serious pest of rice and has tremendous impact especially in Asia-Pacific region. Understanding the biology and ecology of this pest will enhance the designing, formulation and utilization of effective control measures. The control strategies as stipulated by integrated pest management (IPM) should be eco-friendly with minimum use of synthetic pesticides while boosting the activities of natural enemies and other biological control agents. The control measures discussed in this paper are oriented towards the cultural and biological aspects of managing the pest.

Experiments were carried out to assess some insecticide modules against major insect pests of rice. Each module consists of a basal application of carbofuran 3G @ 1 kg a.i ha-1 at 20 DAT and Rynaxypyr 20 SC @ 30 g a.i ha-1 at 45 DAT except untreated control. All modules differ with each other only in third treatment which was applied in 65 DAT. The third treatment includes: Imidacloprid 17.8 SL @ 27 g a.i ha-1, Pymetrozine 50 WG @ 150 g a.i ha-1, Triflumezopyrim 106 SC @ 27 g a.i ha-1, Buprofezin 25 SC @ 250 g a.i ha-1; Glamore (Imidacloprid 40+Ethiprole 40% w/w) 80 WG @ 100 g a.i. ha-1, Thiacloprid 24 SC @ 60 g a.i ha-1, Azadirachtin 0.03 EC @ 8 g a.i ha-1, Dinotefuran 20 SG@ 40 g a.i ha-1 and untreated control. All the treated plots recorded significantly lower percent of dead heart, white ear- head caused by stem borer and silver shoot caused by gall midge. Module with Pymetrozine 50 WG @ 150 g a.i ha-1 treated plot recorded significantly higher per cent reduction of plant hoppers (>80% over untreated control) and produced higher grain yield (50.75 qha-1) than the other modules. Among the different treated modules the maximum number of spiders was found in Azadirachtin 0.03 EC @ 8 g a.i ha-1 treated module plot followed by other treatments.

The insect problem is accentuated in intensive rice cropping where the insects occur throughout the year in overlapping generations. Over 800 insect species damaging rice in one way or another, although the majority of them do very little damage. In India, about a dozen of insect species are of major importance but the economic damage caused by these species varies greatly from field to field and from year to year. Insect pests cause about 10-15 per cent yield losses. Farmers lose an estimated average of 37% of their rice crop to insect pests and diseases every year. This review focuses on precision farming tools being used in rice pest and diseases management viz., forecasting model for real-time pest-advisory services, hyper-spectral remote sensing in pest damage assessment, computer-based decision support system, disruptive technologies (mobile apps).

Kemampuan Indonesia dalam memenuhi kebutuhan beras nasional sangat penting. Akan tetapi, usaha pemenuhan kebutuhan beras ini tidak selamanya berjalan dengan lancar karena terganggunya produktivitas padi. Salah satu penyebab turunnya produktivitas padi di Indonesia karena adanya serangan serangga hama. Beberapa kendala yang menyebabkan gagalnya petani dalam mengendalikan serangga hama karena petani masih belum melakukan identifikasi serangga hama dan gejala serangan dengan baik. Penelitian yang dilaksanakan akhir tahun 2012 ini yang berlokasi di Lahan Persawahan Padi Dataran Tinggi Desa Sukawening, Kecamatan Ciwidey, Kabupaten Bandung, Jawa Barat bertujuan meng inventarisasi dan mendapatkan nilai keragaman jenis serangga hama pada tanaman padi. Penangkapan serangga hama yang dilakukan dengan menggunakan perangkap kuning, perangkap jaring dan perangkap cahaya. Hasil penangkapan serangga diidentifikasi di laboratorium. Indeks keragaman serangga dianalisis dengan menggunakan perhitungan Shannon- Weinner. Serangga hama yang dominan diperoleh pada fase vegetative yaitu Scirpophaga incertulas, Thaia oryzivora, dan Orselia oryzae. Serangga hama minor diperoleh yaitu Dicladispa armigera, Leptispa pygmaea, dan Melanitis ledaismene. Serangga hama yang dominan diperoleh pada fase generative yaitu Leptocorisa acuta, Scirpophaga incertulas, dan Thaiaoryzivora. Serangga hama minor diperoleh yaitu Nilaparvata lugens, Sogatella furcifera, dan Cofana spectra. Indeks keragaman serangga hama yang diperoleh pada ketiga lahan percobaan ada diantara sedang hingga tinggi.Pada fase vegetatif indeks keragaman tertinggi sebesar 4,74 pada pengamatan ke 6 dan terendah pada pengamatan ke 1 sebesar 2,22. Pada fase generatif indeks keragaman tertinggi pada pengamatan ke 9 sebesar 4,86 dan terendah pada pengamatan ke 12 sebesar 1,37.   Kata kunci :indeks keragaman, serangga hama, padi, Kabupaten Bandung.
