Rice stem borer (RSB ) is a major pest for rice in Central Java in the past ten years as well as previous years . The presence of RSB occurs during the rice growing season with a high intensity , especially in the rainy season . RSB which is the main type, yellow RSB Scirpophaga incertulas Walker  and white S. innonata. Walker . Other types are pink  Sesamia inferens Walker , striped Chilo suppressalis Walker, headed black C. polychrysus Meyrick , and shiny C. auricilius Dudgeon. Organic farming in Central Java is still not widely applied so it is still very less information available, including information on the fluctuations in species diversity and population abundance of RSB. In this study examined the types and abundance fluctuations keenekaragaman RSB populations in rice field ecosystem organic and inorganic. Research will be conducted for one year (3 times transplanting rice) paddy ecosystems in organic and inorganic  Bakalrejo Village, District Susukan, Semarang regency. The results showed that the dominant RSB is yellow S. incertulas. Yellow RSB found in every season paddy rice planting in both organic and inorganic rice. While the pink, shiny and white RSB, occasionally encountered. The RSB encountered seem to prefer the ecosystem tend rice paddy organic than inorganic . Keywords : rice stem borer ( RSB ) , organic rice ecosystem, inorganic rice ecosystem.

Three species of parasitoids viz., Telenomus dignus Gahan, Trichogramma japonicum, Ishii and Tetrastichus schoenobii Ferriere were recorded from the egg masses of rice yellow stem borer, Scirpophaga incertulas (Walker) in a field study. The extent of parasitism was high during Rabi (43.33 – 93.33 %) and low during Kharif (0 - 40.00 %). Parasitism by T. dignus was maximum in October (50.00 %), T. japonicum, in November (23.08 %) and T. schoenobii in February (55.55 %). dignus and T. schoenobii in combination parasitized maximum number of egg masses (41.82 %). Multiple parasitism by the three species was high in December (8.33 %) and January (7.14%). Parasitic potential was maximum, when T. schoenobii alone parasitised the egg masses followed by T. dignus and T. schoenobii in combination. Host density in the field influenced the extent of parasitism.

Efficacy Tests of Entomopathogenic Nematodes (Rhabditida:  Steinernema dan Heterorhabditis) as Non-endemic Natural Enemies of Yellow Rice stem Borer (Scirpophaga incertulas). Yellow rice stem borer (Scirpophaga incertulas) is a chronic insect pests of irrigated rice and difficult to control.  Entomopathogenic nematodes from the genus Steinernema and Heterorhabditis are promising biological control agents for this pest as their infective juveniles (IJs) are capable of seeking and infecting insect living in moist, cryptic habitat such as galleries created by stem borer larvae. Thirteen indigenous and exotic Steinernema and Heterorhabditis sprayed to rice seedlings in laboratory with nematodes at concentrations of 0.5 or 2.0×104 IJs ml-1 water caused larval mortality between 7–93%.  Further test in greenhouse on nematodes that had >50%  efficacy showed that an indigenous isolate, H. indicus INA H17, was the most effective among the tested nematodes in killing larvae or pupae (78%).  Reduction in plant damage caused by the insects could not be demonstrated as the trials was limited to potted plants. The survival ability of nematodes on rice plants was evaluated by using INA H4 as an example. A low percentage of INA H4 IJs (0.5%) persisted in inner leaf sheath until 7 days post application, while IJs on leaf surface and outer leaf sheath survived only until 2 and 48 hours post application, respectively. Improvement of application strategies including repeated spray, addition of antidessicant and adjusment of spray volume and application at damage threshold or plant critical period are deemed necessary to enhance nematode efficacy and reduce plant damage in the field.

Abstract The present investigation was based on the management of Yellow stem borer which is a major pest of Basmati rice crop in India. All the treatments were applied to control this pest when it reached on its ETL level. The data recorded one day before of first spray and 3, 7, 10 days after of each spray. The observation revealed that all the treatments were found significantly superior over untreated control. Among the all treatments Fipronil 5 SC was found most effective followed by Imidacloprid 17.8 SC, Cartap hydrochlorid 4 G. Among the bio-pesticides B. bassiana was most effective after the chemical pesticides followed by M. anisopliae and V. lacani. The field treated with fipronil 5 SC produced the highest grain yield (38.35 q/ha) and Imidacloprid 17.8 SC was placed on second place with 37.26 q/ha grain yield followed by Thiamethoxam 25 WG (36.05q/ha) and Cartap hydrochloride 4G (33.87 q/ha).

Major Pest

Rice yellow stem borer, Scirpophaga incertulas (Walker) (Pyralidae: Lepidoptera) is the major pest of rice that causes extensive damage to the crop and its infestation is more severe in summer rice. Field experiment for two consecutive seasons (summer 2014 and 2015) at Bhadrak, Odisha (India) was carried out to assess the relative efficacy of some modules pest management against yellow stem borer and leaf folder in rice. The pest management module comprising of nursery treatment with fipronil 03 G @ 100 g/ cent nursery area at 7 days before transplanting, clipping of leaf tips at transplanting, installation of pheromone traps for mass trapping @ 50/ ha, soil application of chlorantraniliprole 0.4 G @ 10 kg/ ha at 30 DAT and foliar spray of indoxacarb 14.5 SC @500 ml/ ha at 60 DAT minimised the stem borer damage substantially (76.40 and 76.15 % reduction of dead heart and white ear head, respectively over control) and contributed to the highest grain yield ( 42.86 % increase over control) with maximum net return (Rs. 19899.05 per hectare) and B :C ratio (1.46). The current pest management module also reduced the infestation level of leaf folder in rice (60.72 % reduction over the untreated control).

Stem borer is the second important rice pest after rats in Indonesia. A field trial was conducted in Karawang, West Java in dry season of 2003 to study the effect of planting time on the stem borer infestation on seven rice cultivars. The rice cultivars tested were Fatmawati (new plant type cultivar), Gilirang (semi-new plant type cultivar), Maro and Intani 3 (hybrid rice cultivars), and IR72, Cilosari and IR62 (inbreed rice cultivars). The three planting times (PT) were: (1) the early PT, 14 days before farmer’s PT, (2) the common PT, simultaneously with farmer’s PT, and (3) the late PT, 14 days after farmer’s PT. The trial was arranged in a split plot design with four replications. Planting time is the main plot and rice cultivar is the subplot. Fourteen-day old rice seedlings were transplanted at 25 cm x 25 cm planting distance in a 5 m x 6 m plot size. Species and fluctuation of rice stem borer were determined by using water traps containing four synthetic sex pheromone lures of rice stem borer species as attractant. Results showed that the dominant species of stem borer was yellow stem borer (Scirpophaga incertulas Wlk.). Degree of stem borer infestation depended upon the planting time. Stem borer infestation at the first planting time was higher (average 37.90%) compared to those found at the second and third planting time, i.e. 0.65% and 0.54%, respectively. Rice yields of Fatmawati, Gilirang, Maro, Intani-3, and Cilosari cultivars correlated with the degree of stem borer infestation, but did not correlate with planting time. Cilosari cultivar showed the most tolerant under heavily stem borer infestation. The present study implies that adjustment of planting time is the most feasible effort to reduce stem borer infestation because none of the seven rice cultivars tested were able to minimize damage under heavily infestation of yellow stem borer.

Rice stem borer is a main pest of paddy rice in Central Java. The main rice stem borer are yellow rice borer, Scirpophaga incertulas Walker, and white rice borer, S. innonata Walker. Other species are pink borer Sesamia inferens Walker, striped rice borer Chilo suppressalis Walker, dark-headed rice borer, C. polychrysus Meyrick, and glossy rice borer, C. auricilius Dudgeon. Besides rice stem borer, there are many other insect which are potential as rice pest, i.e., grasshopper, rice ear bug, brown planthopper, etc. Organic agriculture in Central Java have not been applied yet, hence there is still lack of information, including species diversity information and abundance of rice stem borer population and other potential insect pest on rice. Species diversity and population abundance of rice stem borer and other potential insect in organic rice ecosystem differ with the inorganic one. The objective of this research is to study species diversity and abundance of rice stem borer population and other potential pest in organic rice ecosystem. The study was conducted in organic rice of Bakalrejo Village, Susukan Sub district, District of Semarang. Species diversity and population abundance was analyzed using Shanon-Wiener’s species diversity index (H’), population abundance index (Di), and population evenness index (e). Pattern of  species diversity, population abundance, population evenness were temporally analyzed using population dynamic curve. Sampling of species diversity and population abundance was performed during a crop planting season with twice of sampling frequency. The result shows that rice stem borer found  were yellow rice borer with its population fluctuated temporally and pink rice borer with  its population were few and scarce. The highest diversity found during rice generative phase until ripen and decline in line with the age of rice. Species diversity index in vegetative phase was below 2, while during generative phase until ripen increased above 2. Insect population abundance declined in the end vegetative phase and increased in the beginning of reproductive phase until ripen phase. Population evenness index in all growth phase of rice were relatively high and similar. Keywords : organic rice, rice stem borer, insect pest of rice.
