An Inventory of Grasshoppers (Orthoptera: Acrididae) in the Plantation and Rice Field Ecosystems of Serdang Menang Village, Sirah Pulau Padang Sub-district, Ogan Komering Ilir District Ari Sugiarto Email: [email protected] Abstract Grasshoppers (Orthoptera: Acrididae) can be a threat to agricultural crops. Serdang Menang Village has a plantation and rice field ecosystems that has potential threats from grasshoppers. An inventory of grasshoppers (Orthoptera: Acrididae) is needed on plantation and rice field ecosystems in Serdang Menang Village as an effort to estimate the potential for contamination of grasshoppers in the plantation and rice field ecosystems. This research was carried out in the plantation and rice field ecosystems of Serdang Menang Village, Sirah Pulau Padang Sub- district, Ogan Komering Ilir District in October 2018. This research method used Sweep net and hand picking, as well as taking photos of grasshoppers with a camera. Species of grasshoppers (Orthoptera: Acrididae) found in the plantation and rice field ecosystems of Serdang Menang Village number 6 species (Gesonula mundata, Oxya Hyla, Phlaeoba fumosa, Valanga nigricornis, Xenocatantops humilis, and Xenocatantops sp.). Species of grasshoppers are more commonly found in the rice field ecosystems than in plantation ecosystems, this can indicate that the rice field ecosystems have a greater potential threat of grasshoppers than in plantation ecosystems. Keywords: Ecosystems, Grasshoppers (Orthoptera: Acrididae), Serdang Menang Village 1. Introduction Grasshoppers are included in the order Plantation, Rice Fields, River and of Orthoptera with an estimated number of Settlements. Seeing the role of species of 20,000 (Borror et al., 2005 in grasshoppers in ecosystems that tend to be Prakoso, 2017). Grasshoppers are not detrimental, it is necessary to do an randomly distributed in the different inventory of grasshoppers in the plantation environments in which they are located. and rice field ecosystems in Serdang Grasshoppers have a distribution pattern Menang Village in an effort to estimate the that is related primarily to the availability of potential of the grasshoppers in the food in various types of vegetation, plantation and rice field ecosystems. anthropic factors, light intensity and canopy (Almeida and Camara, 2008). 2. Research Methods One of family of the order Orthoptera is This the research was conducted in Acrididae. According to Seino et al. (2013), Serdang Menang Village, Sirah Pulau short horned grasshopper from the family Padang Sub-district, Ogan Komering Ilir of Acredidae is a pest on agricultural crops. District in October 2018. Sampling This is also supported by Prakoso (2017), locations were determined on the plantation grasshoppers from family of Acrididae act and rice field ecosystems. Based on the as herbivores in the ecosystems. research by Almeida and Camara (2008), Serdang Menang Village located in grasshoppers are found in various types of Sirah Pulau Padang Sub-district, Ogan vegetation. Grasshoppers sampling was Komering Ilir District consists of several carried out using Sweep net and hand ecosystems, namely the ecosystems of picking (Seino et al., 2013). Grasshoppers that have been identified are then released also carried out with a camera. Species again (Parches et al., 2010). In addition to identification of grasshoppers obtained was catching grasshoppers with Sweep net and carried out by matching the image of hand picking, photos of grasshoppers were grasshoppers that had been identified. 3. Results and Discussion Based on the research that has been done, it is obtained the species results of grasshopper in the plantation and rice field ecosystems of Serdang Menang Village, Sirah Pulau Padang Sub- district, Ogan Komering Ilir District, namely: Table 1.

Species of grasshoppers (Orthoptera: most commonly found in rice field Acrididae) found in the plantation and rice ecosystems that have a lot of shrub, grass field ecosystems of Serdang Menang and shrub vegetation. Species of Gesonula Village numbered 6 species (Gesonula mundata, Oxya Hyla, Xenocatantops mundata, Oxya Hyla, Phlaeoba fumosa, humilis can be easily found in the Valanga nigricornis, Xenocatantops ecosystems of this rice field ecosystems. humilis, and Xenocatantops sp.)

According to (Orthoptera: Acrididae) in the plantation Seino et al.

According to Seino et al. management. (2013), short horned grasshoppers from the Table 2.
