One of the rice producing regions in Indonesia is South Sulawesi. Wajo Regency is the second highest rice producing area in South Sulawesi, after Bone Regency. Based on the irrigation system, rice cultivation in Wajo Regency consists of technical irrigation, rainfed rice fields, and rice cultivation or dry land. Agriculture with various irrigation systems has an impact on pest population levels and the intensity of attacks. The decline in rice productivity is caused by many factors, one of which is the attack of rice rat pests that occur in several areas in Wajo Regency. There are several techniques and strategies for field rat management, ranging from sanitation, technical culture or plant cultivation, mechanical, biological, and chemical physical. All techniques and strategies of rice rat management must be applied integrated, continuously, and together in one stretch. This study aims to measure the potential presence of rice rats in several irrigation systems in Wajo Regency (irrigation, rainfed rice fields, and dryland rice), analyze the management of rice rats carried out by farmers, and the factors that affect it. The method used is observing rice planting patterns based on irrigation systems, estimating the population level of rice rats with single live traps and the level of attack on several rice planting irrigation systems. Likewise, rice rat population management in several rice planting irrigation systems, data analysis, and economic analysis. The result of this study is that the highest estimate of rats is in dryland rice plantations. The intensity of rat attacks was highest in dry land Pr>F 0.045 the area of attack was highest in rainfed land Pr>F was 0.0171, for intensity and area of attack in generative phase 1. The success of cultivation in dry land was 16.3% in generative phase 1 which was 16.48%. The presence of rats correlates both the intensity of the attack and the area of each addition of rats will increase the intensity of the attack by 0.155% and the area of attack by 0.308%.

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.

Cassava is one of the food commodities in Indonesia, but its productivity often decreases due to mealybug attacks (Hemiptera: Pseudococcidae). This study aims to determine the type and abundance of mealybugs and the ecological relationships between them and their natural enemies on cassava plants. The sampling method employed was purposive sampling, involving the selection of 100 sample plants per location, namely Benteng Village and Pasirlaya Village, in Bogor Regency. Mealybug and parasitoid samples were taken from three infested leaves, while predators were collected from the plant canopy. Identification was carried out morphologically to the species level, analyzed using the ecological index, and compared using the Mann-Whitney test (P = 0.05). The study’s results identified four species of mealybugs: Paracoccus marginatus Williams & Granara de Willink, Ferrisia virgata (Cockerell), Pseudococcus jackbeardsleyi (Gimpel & Miller), and Phenacoccus manihoti Matile-Ferrero. Natural enemies of mealybugs found from the predator group were Cryptolaemus montrouzieri Mulsant, Plesiochrysa ramburi (Schneider), Scymnus sp.1, Scymnus sp.2, Theridion sp., and from the parasitoid group, namely Anagyrus lopezi (De Santis), Acerophagus papayae Noyes & Schauff. The diversity, evenness, and richness indices of arthropod species were higher in Pasirlaya, while dominance was higher in Benteng. The parasitization rate of A. papayae and A. lopezi was more stable in Pasirlaya, although the arthropod population did not differ significantly between locations (P = 0,31). This study concluded that Pa. marginatus and Ph. manihoti were the dominant mealybug species, with predators Theridion sp. and C. montrouzieri as the most abundant natural enemies, The parasitoid A. lopezi was known to parasitize Ph. manihoti, and A. papayae parasitized Pa. marginatus.

Pests in the agricultural sector cause huge losses to farmers' production and income. Sustainable pest management, such as the utilization of natural predators, is important to maintain agricultural productivity. In Banyuwangi, East Java, Indonesia fruit-eating bats pose a threat to horticultural yields, although their ecological roles as pollinators and seed dispersers are recognized. Conflicts between bat conservation efforts and farmers' needs arise because most farmers view bats as pests. This study examines farmers' perceptions of bats and their participation in bat conservation in Banyuwangi, as well as the factors that influence their attitudes. Based on interviews and data analysis in three sub-districts, this study found that farmers' knowledge on the benefits of bats is not always directly proportional to their positive attitude towards them. To resolve this conflict, a management strategy that includes education, incentives and collaboration with farmers is suggested. Through this approach, a balance between bat conservation and agriculture sustainability is expected to be realized, providing long-term benefits for the ecosystem and agricultural productivity in the region.
