Abstract

Hymenoptera are vital for maintaining ecological balance in rice agroecosystems. These insects provide essential ecosystem services, particularly in biological pest control, reducing the reliance on chemical pesticides. Despite their importance, the impact of different agricultural practices on Hymenoptera diversity and their ecological roles in Indonesian rice fields remains underexplored. This systematic review aims to assess the diversity and ecological functions of Hymenoptera in Indonesian rice agroecosystems, evaluate their contributions to natural pest suppression, and examine how various management practices, including organic farming and Integrated Pest Management (IPM), affect Hymenoptera populations. A comprehensive search of peer-reviewed studies from Scopus, Web of Science, and Google Scholar was conducted. Inclusion criteria focused on studies reporting Hymenoptera species diversity, ecological roles, and the effects of different rice farming practices. Data on species composition, pest suppression rates, and management practices were synthesized and analyzed using statistical methods, including regression and ANOVA.The findings reveal significant variation in Hymenoptera diversity across regions, with organic and IPM practices supporting higher species richness than conventional methods. A strong positive correlation was found between Hymenoptera diversity and pest suppression rates, particularly during the reproductive stage of rice growth. Parasitoids and predators played dominant roles in controlling key rice pests.Conserving Hymenoptera diversity through sustainable farming practices is crucial for reducing chemical inputs, improving pest control, and enhancing the resilience of rice agroecosystems. Future agricultural strategies should integrate biodiversity-friendly practices to ensure long-term sustainability in rice production.

Abstract

Insect diversity in plantations is crucial for understanding the ecological roles of each species and managing pest-related issues. This study aimed to assess the diversity of insects in Siam citrus (Citrus nobilis Lour.) plantations in Sungkai, Padang City, Indonesia, focusing on the implications for pest management. A survey was conducted in the Siam citrus plantation, categorizing sampling sites into three groups based on the distance from the forest (20, 40, and 60 m from the forest). Insect samples were collected by spraying the plants with insecticides, hand-picking, and trapping insects on a white cloth. The results showed that the number of insect species found at the sites was 19, 18, and 12 at 20, 40, and 60 m from the forest, respectively. The species identified included Bractocera spp., Toxoptera sp., Aphis gossypii, Bothrogonia sp., Planococcus citri, Sanurus sp., Rhynchocoris humeralis, Conocephalus sp., and Valanga nigricornis as pests, and Blattella sp., Hemithyrsocera sp., Coccinella transversalis, Nylanderia sp., Polyrhachis sp., Dolichoderus sp., Anoplolepis gracilipes, Hierodula sp., and Hierodula sp1 as predators, with Lasioglossum sp. identified as a pollinator. The species diversity at each site was categorized as medium, with diversity index values of 2.10, 2.07, and 1.95, respectively. Species evenness was categorized as high, with index values of 0.71, 0.72, and 0.78, respectively. This study provides valuable data on the pest and predator populations in citrus plantations, which can inform sustainable pest management strategies to improve crop health and productivity.

Abstract

Termites are one of the organisms that have the potential to reduce oil palm productivity, so it is necessary to identify the species and map their distribution to support more effective and sustainable management. This study was conducted to identify termite species and map their distribution in oil palm plantations in Timpeh District, Dharmasraya Regency, Indonesia. This study used a survey method with purposive sampling based on several criteria, including the presence of plant attack symptoms, air humidity ≥ 60%, the presence of rotten wood, the presence of termite nests, and the sampling location was selected in oil palm plantation areas located on the edge of local roads at a distance of about 0-15 meters. The termite samples obtained were identified morphologically using a microscope and identification keys. Termite distribution mapping was performed using ArcGIS 10.8 software, while the relationship between termite presence and environmental factors (temperature, light intensity, and humidity) was analyzed using Redundancy Analysis (RDA). The results showed that there were six termite species in Timpeh Subdistrict, namely Macrotermes gilvus, Coptotermes curvignathus, Pericapritermes mohri, Dicuspiditermes nemorosus, Nasutitermes longinasus, and Termes propinquus. The species M. gilvus has the widest distribution throughout the subdistrict and is not significantly influenced by environmental factors, but rather by its high adaptability. Meanwhile, the other species have a more limited distribution and tend to be influenced by factors such as humidity, light intensity, and the availability of organic material. The mapping results provide a crucial basis for determining priority areas for control and termite management strategies in oil palm plantations, enabling more effective and efficient approaches to be implemented.

Abstract

An evaluation of the suitability of land for sugar palm cultivation was conducted to assess the land's ability to support maximum growth and production. Palm cultivation in Nagari Labuah Gunuang, Limapuluh Kota Regency, has not been optimal because the plants still grow wild without regard to land suitability. This study aims to determine the actual and potential land suitability classes and map land suitability for palm cultivation development. This study employed a field survey using the purposive sampling method on four land units, with sample point criteria selected based on overlay results and representing each land map unit. Additionally, soil sampling was conducted at a depth of 0–60 cm, followed by laboratory analysis. Land suitability was evaluated using a matching method that matched land characteristics with the requirements for palm tree growth. Spatial analysis was then performed using ArcGIS software to produce a land suitability map. The results showed that land suitability classes in Nagari Labuah Gunuang varied. Land units 1 and 4 were classified as unsuitable because they had a slope of more than 40%, while land units 2 and 3 were classified as marginally suitable with a slope of 15–25%. The main limiting factor on land units 2 and 3 is the risk of erosion. After improvement measures such as terrace construction and planting of ground cover crops, the potential suitability class of land units 2 and 3 can be upgraded to moderately suitable. The development of sugar palm cultivation in Nagari Labuah Gunuang can be carried out on land units 2 and 3.

Abstract

Pest attacks on rice plants can cause a detrimental decrease in production. Hymenoptera has many important roles in ecosystems, including as parasitoids and predators of pests. The purpose of this study was to determine the presence of Hymenoptera around tidal swamp rice in Indragiri Hilir Regency, Indonesia. Sampling used four traps, namely: 1) swing net; 2) yellow pan trap; 3) malaise trap; and 4) pitfall traps. The analysis was carried out by calculating the Shannon-Wiener diversity index (H'), the Margalef species richness index (D), the Pielou species evenness index (J). Hymenoptera found around tidal swamp rice areas of Indragiri Hilir Regency were 15.253 Hymenoptera insects consisting of 11 superfamilies, 37 families, and 304 morphospecies. Hymenoptera parasitoid had the highest diversity index value (4,80), followed by Hymenoptera pollinator (3,13) and Hymenoptera predator (3,11). The number of species of Hymenoptera parasitoid, pollinator, and predator obtained was 243; 31 and 76 species. The high diversity of Hymenoptera around tidal agricultural land optimizes its ecological role in the rice plantation ecosystem.
