Diversity of grasshopper in Lingsar Vegetable Field, West Lombok

Abstract

Vegetables are one of the commodities that support the economic sector. Many factors affect the success rate of vegetable production, including pests. Grasshoppers are herbivorous insects that have the potential as pests that will affect crop yields, especially vegetables. This study aims to determine the diversity of grasshoppers in the vegetable field of Bug-Bug Village, Lingsar District, West Lombok. Sampling was carried out on vegetables with differences in plant age, namely 1, 2, and 3 months using the sweeping net method in the morning (07.00-10.30) around the edge and middle of the vegetable field. It is found that there are eight types of grasshoppers in 2 sub-orders and three families (Acrididae (6 species), Pyrgomorphidae (1 species), Tettigoniidae (1 species)). Atractomorpha crenulata and Oxya japonica were grasshopper species with the highest relative abundances of 42% and 29%, respectively. The analysis showed that the diversity index (H') of grasshoppers found in the research location was 1.5445.

Study of species richness of grasshopper (ordo orthoptera) in Beriri Jarak, Lombok Island, Indonesia

“…Middle, namely, nine species [11]. The species richness of locusts found in Beriri Jarak is also greater than that found in the vegetable fields in Suranadi [12]. However, these species are less than those found in Malang, East Java, which totaled 30 species [13].…”

“…Likewise with plants that are in the field path, for example, sitting (Melastoma sp. ), Mimosa (Mimosa pudica L.), weeds (Imperata cylindrica L), fern (Stenochama polushis L) in plain sight [19][20].…”

Diversity of Grasshopper (Hexapoda: Orthoptera) in the Conservation Area of Kerandangan Natur Park, Senggigi, West Lombok

“…Each specimen is identified to the species taxon. We used the identification book from Tan and Iorio [15][16][17] and several articles published in journals such as Suranadi and Dompu [11][12][13]. In addition to species data, we recorded the number of each species identified.…”

“…The ecological variables analyzed include relative abundance, richness index, diversity index, and species evenness index. Relative abundance refers to the equation used by Ilhamdi [11]. .…”

“…On Lombok Island, only 2 studies have explored information about these animals. These two studies were conducted in vegetable fields in the Lingsar area, West Lombok [11],…”
