Abstract

The objectives of this study were to examine the characteristics of the landscape at each research site to examine the diversity, abundance, and composition of beetles; to examine the effect of management practices and habitat conditions, and to examine the relationship between landscape composition and beetle diversity and abundance at 14 research sites. The research was conducted from January 2022 to March 2022 in 14 rice farming locations spread across West Sumatra, Central Java, and East Java. Sampling was done by installing light traps at each location, mapping the landscape condition, and characterizing the landscape by conducting a ground survey at a radius of 500 m from the observation plot by recording various types of land use and then digitizing it with the QGIS application version 3.24.1. This study used analysis of variance and regression analysis. The results showed that plantations, agriculture, forests, and settlements dominated the land use types. The total number of beetles was 12,653, consisting of 10 families and 24 morphospecies. The cultivation method that influences the diversity of beetles is the application of fertilizer, while the landscape composition that affects species diversity is natural habitat and class area plantation.

Abstract

Complex rice systems are a type of farming system that provides shelter for various insects, thereby reducing pests and plant diseases while enhancing farmer's economies. Plants and other components integrated with rice enhance beetle diversity and abundance in complex rice systems. This study aimed to determine the diversity and abundance of beetles in a complex rice system and the factors that can influence them. The study was conducted on a complex rice system farm in Sukorejo Village, Gondanglegi District, Malang Regency. Observations were made five, seven, and nine weeks after planting the rice. Beetles were sampled using pitfall traps and farmcop traps. The results showed differences in the diversity and abundance of beetles between farms with monoculture systems and those with complex rice systems. However, plant age, temperature, and humidity did not correlate with beetle diversity and abundance. This research concludes that complex rice systems are better than monoculture systems.

Abstract

Cabbage (Brassica oleracea var. capitata) is a vegetable with significant potential for cultivation due to its high economic value. However, cabbage production experiences fluctuations each year primarily due to pest factors. To control these pests, natural enemies such as ants can be utilized. Ants are highly sensitive to changes in their habitat, making them known as environmental bioindicators. Additionally, landscape structure can influence the presence of insects, including predators and parasitoids. This study aims to determine the effects of cultivation methods, habitat conditions, and landscape composition on ant diversity and abundance. The research was conducted from November 2022 to May 2023 across 12 fields in four different sub-districts: Pujon, Tumpang, Poncokusumo, and Purwodadi. The research process included landscape mapping and characterization, determination of observation plots, trap installation and sampling, species identification, collection of supporting data, and data analysis. The study yielded a total of 4,053 individuals representing 26 genera and 52 morphospecies. The ant species with the highest abundance was Lophomyrmex sp.3, while the greatest diversity was observed within the genus Tetramorium. Insecticide application and plant age did not significantly affect ant diversity and abundance; however, elevation did influence ant abundance. Additionally, landscape composition, particularly the class area (CA) of natural habitats, correlated positively with both ant diversity and abundance.

Abstract

Cabbage (Brassica oleracea) is a vegetable crop with high commercial value in Indonesia. However, cabbage production still fails to meet consumer demand, with one of the causes being pest damage. Plant pest can be suppressed and controlled using natural enemies from various orders, including Coleoptera or beetles. Cultivation practices and landscape composition influence the presence of beetles. This study aims to investigate the characteristics of the landscape, the role of beetles, and the relationship between cultivation methods and landscape composition on the diversity, abundance, and composition of beetles. The research methods include determining the location and observation plots, mapping the landscape and characterizing the composition of the landscape, and setting traps for sampling, identification, and documentation. Data analysis used analysis of variance, analysis of similarity, and Generalized Linear Models (GLM). All data analyses were performed using RStudio software and the vegan package. Based on the research results, the dominant land use types are agriculture and natural habitats; beetles consist of predatory, herbivorous, decomposer, and scavenger beetles. Cultivation methods did not correlate with beetle diversity, abundance, and composition, whereas habitat conditions and landscape composition did correlate with beetle diversity, abundance, and composition.

Abstract

The existence of Hymenoptera parasitoids can be influenced by the landscape structure of agricultural land. Optimization of pest control using natural enemies can be done on a landscape scale. This study aimed to examine the characteristics of the rice cultivation landscape at each research location, examine the diversity of Hymenoptera parasitoids and their role in rice cultivation. In addition, this study aims to examine the factors that influence the diversity and abundance of Hymenoptera parasitoids, as well as examine the effect of landscape composition on the diversity and abundance of Hymenoptera parasitoids in rice cultivation in Malang Regency, East Java. The research was conducted at various designated rice planting locations. The research locations were in 4 sub-districts, namely Karangploso, Lawang, Kepanjen, and Tumpang sub-districts with three sampling points in each of these sub-districts. The research began with determining the location or ground survey. Insects were sampled using yellow pan traps,  with two traps installed in each subplot. Samples preserved in vials containing 70% alcohol were then sorted into microtubes according to sampling order, and specimens were examined morphologically to determine morphospecies. Supporting data were obtained from interviews with farmers or land owners. All data were entered into a database in Microsoft Excel and spreadsheets and analyzed using RStudio. The results indicated that the 12 study sites varied widely and were classified as complex landscapes, comprising eight land-use types dominated by natural habitats, paddy fields, and settlements. Hymenoptera parasitoids were found consisting of 8 families and 21 morphospecies. The parasitoids found act as parasitoids of eggs, larvae, eggs-larvae, and larvae-pupae. Altitude and age factors correlated with the diversity of Hymenoptera parasitoids. Landscape composition metrics, including Number of Patches (NP) and Class Area (CA) of rice fields, were correlated with the diversity and abundance of individual parasitoids.
