Abstract
The presence of the parasitic Hymenoptera plays a vital role in pest management for sustainable agriculture. So, it is crucial to know the parasitoid species that exist in an agroecosystem. Sweep Net, Yellow Pan Trap, and Malaise Trap are often used to study the diversity of Hymenoptera parasitic in agroecosystems. This study aims to see the effectiveness of Sweep Net, Yellow Pan Trap, and Malaise Trap in trapping Parasitic Hymenoptera. The study was carried out at four sub-districts, namely are Batang Tuaka, Keritang, Reteh, and Tembilahan Hulu sub-district. The research was carried out by sampling with the transect line method. Sweep net, Yellow pan trap, and Malaise trap have trapped 5,732 individuals of Parasitic Hymenoptera on tidal swamp rice in Indragiri Hilir Regency. The Parasitic Hymenoptera consists of 10 superfamilies, 30 families, and 320 morphospecies. Malaise traps are the best for trapping parasitic Hymenoptera on tidal swamp rice. Malaise traps have been able to trap up to 62% of morphospecies and 81% of the abundance of individual Parasitic Hymenoptera on tidal swamp rice. Yellow pan traps trap 28% of morphospecies and 15% of the abundance of individual Parasitic Hymenoptera. The sweep net can trap 10% of morphospecies and 4% of the abundance of individual Parasitic Hymenoptera.Keywords: Parasitic Hymenoptera; trap; tidal swamp rice.

Summary
The use of natural enemies is necessary to support sustainable agriculture. Sustainable agriculture approaches take advantage of natural enemies such as predators, parasitic insects, and pathogens to manage pests in agroecosystems. An extensive evolutionary group of Hymenoptera insects, are well-known as biological control agents for arthropod pests in agricultural ecosystems. Hymenoptera has many important roles in ecosystems, namely as a pollinator, bioindicator, predator, and parasitoid (Triplehorn and Johnson, 2004; Anderson et al, 2011). About 80% of the Hymenoptera group is dominated by parasitoid species (Quicke, 1997; Saputra et al, 2017). Parasitic Hymenoptera is a natural control agent for insects, mainly in the agroecosystem. It is crucial to know the parasitoid species that exist in an agroecosystem
