Abstract

The Eurasian tree sparrow (Passer montanus L.) known as both pest and predators; in the urban area, it is considered a pest because of its droppings, feathers, and nests around the house. Meanwhile, in rural areas, it is considered both pests and predators because their diets are small insects and small grains like a grain in the rice field. This study aimed to determine the daily consumption rate of sparrows on grain; their preferred food; identify the adaptability; and the role of sparrows in urban and rural areas. Feeding ability test using the no-choice baiting method. Food preference test using the choice baiting method. The adaptability and role of sparrow data are obtained through location determination and direct observation in the field. The results show that the consumption rate of individual sparrow is ten percent of body weight. The most preferred food for sparrow is yellow mealworm, followed by millet, cricket, foxtail millet, rice grain, and corn. The Eurasian tree sparrow is not considered a pest on rice fields. The presence of the sparrow in urban areas is less than in rural areas. Both in urban and rural areas, more sparrows were seen or found in the morning than in the afternoon. Sparrows can adapt well in rural and urban areas because the environment provides open area and house building. In urban areas, sparrow is considered urban pests; meanwhile in rural areas they potentially considered a pest on barley and millet, and predators on small insects.

Abstract

Environmentally friendly control using biological methods for rice field rats is currently being carried out, one of which is using the natural enemy of rice field rats, namely the owl predator which can control rice field rat pests without damaging rice and land or causing pollution. This research aims to evaluate the value of losses experienced by farmers caused by rice field rat pests in Karawang Regency, analyze farmers' perceptions and behavior towards controlling rice field rat pests using owls, implementation of rice field rat pest control in Karawang Regency, and policy priorities that can be implemented and taken to optimize the sustainable use of owls in the context of controlling rice field rat pests in Karawang Regency. The method used is a survey and field observation which includes observing the number of active rat nests, calculating the percentage of attacks, calculating the number of owls after introduction, calculating crop production, and farmers' perceptions of controlling field rats using owls, as well as data analysis. Results showed that the use of owls is effective in controlling rice field rat pests, this is shown by the correlation between the high number of owls and the reduced level of rat attacks in rice field areas. Keywords: Ricefield rat, Owl, Policy, Predator, Rice.

Abstract

The production of rice is closely related to the presence of pests, one of which is the rice field rat (Rattus argentiventer). The development of pests that attack plants is influenced by the dynamics of climate factors, both directly and indirectly. The climate in Karawang Regency is highly suitable for the growth of R. argentiventer. In the rice - rice - intercrop cropping pattern, climate factors have strong influence on the infestation of rice field rats during the intercrop season. Meanwhile, climate factors have low influence during the rice monocrop season. Based on CLIMEX output, the altitude difference in Karawang Regency does not have a significant effect on the environment suitability for the growth and development of rice field rats, allowing them to live in any rice field in Karawang Regency. Based on climate scenarios, the suitability of the climate in Karawang Regency for the potential growth and development of rice field rats is projected to decrease in the 2070s. Increasing temperatures and decreasing rainfall cause the rice field rats to experience dry stress.

Abstract

Termite, is one of the most damaging pest for wood product. One of the common fumigant use to control termite is sulfuryl fluoride. The objective of this study were to determine the dose-exposure and time for sulfuryl fluoride to kill dry wood termite Cryptotermes cynocephalus Kemner and evaluate the ability of fumigant to penetrate a rubber wood block. Application and penetration of the fumigant was tested on a 10 cm depth wood block, and conducted with 5 varied doses (10−30 g/m3) and 4 varied exposure time (6−24 hours). Application of the fumigant were tested on an 5 and 2.5 cm depth wood block. Doses were applied using 4 (four) different doses (2−15 g/m3) and 4 varied exposure time (1−9 hours). The study was conducted using randomize completely design with factorials. Results showed the application of sulfuryl fluoride was effective in penetrate 10 cm depth of wood block. The dose that was effective was of 30 g/m3 with 18 hours exposure time or a dose of 15 g/m3 with 24 hours exposure time. Application of depth penetration of 5 cm effectively done by using a dose of 10 g/m3 with 9 hours exposure and depth penetration of 2.5 cm using a dose of 15 g/m3 with 6 hours exposure time. Dose-time relationship for application of sulfuryl fluoride to penetrate of 10 cm showed dose variable is a slightly more important than exposure time, while to penetration of 5 and 2.5 cm showed exposure time variable is a slightly more important than dose of fumigant.
