This community services activity was conducted together with a partner that is Benong II Farmers Group, in the Kalibuaya Village, Telaga Sari, Karawang. The problem that faced by partners is a lack of understanding of plant pest organisms (OPT), especially plant pests and diseases, as well as a lack of knowledge about the natural enemies. Knowledge and skills of the Benong II Farmers Group in the Kalibuaya Village, Telaga Sari, Karawang regarding the management and control of rice stem borer that environmentally friendly, especially biological control using parasitoid Trichogramma sp. needs to be improved. The evaluation results show that counselling and training on the breeding of natural enemies Trichogramma sp. resulting in the development and progress of the behavior, attitudes, and skills of farmers. There are four main results of the research. The results are (1) farmer more understand of the use of biological agents for IPM-based rice pest and disease control; (2) want to implement the control of rice stem borer Scirpophaga sp. by using Trichogramma sp.; (3) more skilled in monitoring the presence or absence of pests in rice plantations in the field; and (4) more active in finding out to community service teams, farmer group leaders, and POPT / field extension officers about how to mass culture theTrichogramma sp. and it’s release techniques in the field.

Sakir et al, 2018. Utilization of Refugia in Increasing Rice Production Based on Local Wisdom. JLSO 7(1): The use of refugia as a habitat for natural enemies of rice pest organisms has not been widely used by farmers on an ongoing basis in preserving the environment.  Therefore, this research aimed to observe  the effect of utilizing refugia on rice production. Based on observations for 18 weeks in 3 hectares rice field, field with refugia harbored an abundance of natural enemies or predators including dome beetles (Micraspis sp.), Tomcat (Paederus littoralis), needle dragonflies (Zygoptera sp), praying grasshoppers (Stagmomantis carolina), spiders hunters (Oxyopes javanus), nets making spider (Tetragnatha maxillosa), and wasps (Polistes sp.). Insect pest infestations of white pest/leaf roller (Nymphula depunctalis), fake white pest/leaf folding (Cnaphlacorosis medinalis), white rice stem borer (Tryporyza innotata), and walang sangit (Leptocorisa acuta) was low. The rice field with plant refugia in 2018 produced 8.13 tons compared to 5.4 tons of rice grain/ha of the preceding year (2017) of yield without refugia. Plant refugia can be applied to increase swamp rice yield.

Rice Stem Borer

Rice is the staple food of Indonesia's population. Various problems occur in an effort to increase production and productivity. One problem is the attack of yellow rice stem borer (PBPK) which may result in yield losses up to 90%. Utilization of parasitoid is an alternative to suppress the attack of Yellow Rice Stem Borer. The study was conducted in Tabanan, covering three locations with the altitudes of 50, 300, and 550 meters above sea leve, and at the Plant Pests and Diseases laboratory of the Faculty of Agriculture, University of Udayana. The study aimed to determine the effectiveness of parasitization of the best Yellow Rice Stem Borer as a natural control agent at different altitudes. The method used was survey by taking a sample group of Yellow Rice Stem Borer eggs with a purposive random sampling in the area of 2.5 hectares (one block in each location was an area of 0.5 hectares) at each location. Observations on parasitoid found in Yellow Rice Stem Borer eggs were done on parasitoid species diversity, equality, abundance, parasitation level, sex ratio, and the pattern of parasitoid invasion. The results showed three species of parasitoid eggs PBPK as biological control agents. Parasitation level of T. rowani and T. japonicum was the highest at the altitude of 50 meters above sea level, while T. schoenobii at the altitude of 300 and 500 meters above sea level.

ABSTRACT The purpose of this research is to know  the pest species in wetland rice crops at Makalonsow Village of East Tondano Distric in Minahasa Regency. The study used a descriptive obsevational method that is observing directly the pests found in rice paddy fields by means of sweeping with insect net and observing directly on paddy fields plaot and paddy fields clumps. The identified pests were identified and made in accordance with the results of identification for each species of pest.  The results showed that 11 species of pests and 4 spesies of natural enemies found in paddy fields of wetland rice at Makalonsow Village of East Tondano District in Minahasa Regency.  The pests are White Rice Stem Borer (Tryporyza innotata), Rice Cherry Stem Borer (Chilo suppressalis), Purple Rice Stem Borer (Sesamia inferens), White Pest (Nymphula depunctalis), Brown Planthopper (Nephotettix virescens), Green Planthopper (Nilaparvata lugens), Paddy Stink Bug (Leptocorisa acuta), Black Lady Bug (Pareaucosmetus sp.), Rice Weevil   (Sitophilus oryzae), Golden Snail (Pomacea caniculata), Hous and Tre Sparow (Passer spp.), and Rice-field Rat (Ratus argentiventer.).

Effects Of Radiation

Germ cells from the rice stem borer Chilo suppresalis, were examined by light and electron microscopy. Damages to organelles within the germ cells were observed. The mitochondria, which provide the cell with metabolic energy, were seen to disintegrate within the germ cell. Lysosomes within the germ cell were also seen to disintegrate. The subsequent release of hydrolytic enzymesmay be responsible for the destruction of organelles within the germ cell. Insect spermatozoa were seen to lose the ability to move because of radiation treatment. Damage to the centrioles, one of which is in contact with the tail, may be involved in causing sperm immobility.

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).
