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.

AbstractThe Wagner Natural Area, located 8 km west of Edmonton, Alberta (53°34′N 113°47′W), contains a boreal spring fen estimated to be 4700 years old. The site was selected in 1985 for a survey of its arthropod fauna. A transect of the site from marl pools through fen, edge effect, and treed swamp was sampled for arthropods using pan and Malaise traps. Specialized microhabitats outside the transect were identified and sampled using pan traps. The Wagner fen samples contain 2181 species of arthropods contributing to a total known biota of 2905 species in the peatland. Of those, 1410 are Hymenoptera. Although seven other peatland studies are known, the inability of systematists to name most species prevents direct comparisons among peatlands. Data obtained from the Hymenoptera collections at Wagner demonstrate a progression in species richness as one approaches the forest–fen edge from either fen or forest. A large proportion [30% (382 species)] of Hymenoptera species, termed the aerial component, is active both in the forest–fen edge and in the fen. The aerial component is a highly mobile, at least locally transient, but often uncollected component of peatland ecosystems. Presence of the aerial component is probably associated with habitat structure. Those peatlands possessing more complex vegetation architecture have greater proportions of aerial species. About 80% of Hymenoptera at Wagner are parasitoids, most of which attack larva of holometabolous hosts. Based on the host groups sought by parasitoids and the ratio of parasitoid species per host species, the fen is estimated to contain about 6000 species of arthropods.

AbstractThe influence of various aspects of Malaise trap design on efficiency in collecting various groups of Hymenoptera was compared using commercially available traps. The influence of fine and coarse mesh sizes and the importance of the incorporation of pan traps into the design were evaluated in two sampling periods in an old dune community at Pinery Provincial Park in southern Ontario. Numbers of individuals collected in Malaise trap heads and pan traps were presented for each paired comparison of mesh size (fine and coarse) and location (top and bottom of a hill) for various families of Hymenoptera. A graphical analysis of the normalized catch data for more inclusive groupings, viz. Symphyta, Aculeata, Ichneumonoidea, and microhymenoptera, was presented. The major results of these comparisons were as follows: (1) pan traps were an important component of efficient Malaise traps, especially for Aculeata and microhymenoptera; (2) coarse mesh was more effective in collecting Aculeata; (3) coarse and fine mesh were both effective in collecting Ichneumonoidea; and (4) fine mesh was more effective in collecting microhymenoptera. There was an interaction effect between the type of trap used and groups collected and it was not possible to maximize simultaneously the collection of all groups of Hymenoptera. The use of various mesh types and a trap design that incorporates pan traps was recommended.

Diversity of parasitic Hymenoptera in different ecosystem types in Central Bangka, Bangka-Belitung Islands.Hymenoptera richness is dominated by parasitic species. More than 80% of Hymenoptera play a role as parasitoid on arthropods that are mostly insects. Diversity of parasitic Hymenoptera is widely studied in various types of terrestrial ecosystems including agro-ecosystem and non-agro-ecosystem. This study aimed to invent and compare the diversity of parasitic Hymenoptera in three different ecosystems, i.e., forest, oil palm plantation, and ex-tin mining. The location was located in Central Bangka Regency, Bangka Island. The study was conducted in Juli 2014 until October 2015. Parasitic Hymenoptera was collected with insect sweep net and yellow pan trap on one transect line with 1000 m length. Parasitic Hymenoptera were found on forest as much as 732 morphospecies, 326 morphospecies on oil palm plantations, and 293 morphospecies on ex-tin mining. Diversity and abundance of parasitic Hymenoptera on forest was higher than oil palm plantation and ex-tin mining area. Braconidae family was found dominant on forest, however on oil palm plantation and extin mining area the dominant family was Scelionidae.

AbstractA survey of muscid flies from Churchill, Manitoba, Canada, in 2007 yielded 155 species. Some components of species richness and composition of this contemporary assemblage were compared with those of a historical (pre-1965) assemblage, and the contribution of the three collecting methods used in the 2007 survey protocol was evaluated. Estimates of species richness indicated that Malaise traps yielded more species than did pan traps or sweep netting, and that species composition did not differ significantly between Malaise trap and pan trap catches. These results suggest that Malaise traps and sweep netting are adequate methods to survey northern Muscidae. We report little difference in estimated species richness and composition between time periods for material collected by sweep netting. When all material from the 2007 survey was pooled, 87% of the pre-1965 species were collected again in 2007. Most nonoverlapping species between time periods were rare in samples and (or) collected by different methods, suggesting a failure to detect as the most likely explanation for their absence in one assemblage. Nevertheless, the proportion of aquatic and semiaquatic species of Spilogona Schnabl was more than twice as high in the list of species not recovered in 2007 than in the pre-1965 assemblage.

Malaise Traps

The Southernmost region of Australia, the island of Tasmania, is also the most mountainous, with large areas of rugged alpine environments. This entomological frontier offers a distinct suite of insects for study including many endemic taxa. However, harsh weather, remote locations and rough terrain represent an environment too extreme for many existing insect trap designs. We report here on the design and efficacy of a new Alpine Malaise Trap (AMT), which can be readily hybridised with several other common insect trapping techniques. Advantages of the design include its light weight and portability, low cost, robustness, rapid deployment and long autonomous sampling period. The AMT was field tested in the Tasmanian highlands (AUST) in 2017. A total of 16 orders were collected. As expected, samples are dominated by Diptera. However, the trap also collected a range of flightless taxa including endemic and apterous species, Apteropanorpatasmanica – closest relative of the boreal, snow scorpionflies (Boreidae). Combined and compared with other trap types the Alpine Malaise Traps captured less specimens but of a greater diversity than passive sticky traps, while drop traps captured less specimens but a greater diversity than AMT. The statistical potential of the catch is discussed.

Abstract. Ikhsan Z, Hidrayani, Yaherwandi, Hamid H. 2020. The diversity and abundance of Hymenoptera insects on tidal swamp rice field in Indragiri Hilir District, Indonesia. Biodiversitas 21: 1020-1026. Hymenoptera is one of the four largest insect orders and it plays a vital role in human life as pollinators, parasitoids, and predators. Hymenoptera parasitoids are particularly important as agents of biological control of pest. The objective of this research was to study the diversity and abundance of Hymenoptera on tidal swamp rice field in Indragiri Hilir District, Riau Province, Indonesia. Samplings were conducted in 3 sub-districts of rice production centers, namely Batang Tuaka, Keritang and Reteh, using four trapping techniques (i.e. insect net, malaise trap, pitfall trap, and yellow pan trap). Shannon diversity index (H '), Krebs evenness index (E), and Jaccard similarity index (Is) were calculated. We found 4,701 individuals consisting of 39 families and 319 species of Hymenoptera at the three studied areas. Tidal swamp rice in Indragiri Hilir District had a high species diversity of Hymenoptera parasitoids and Hymenoptera predators, but a moderate species diversity of Hymenoptera pollinators. Species diversity and evenness of Hymenoptera parasitoids and predators were higher in Keritang than in Batang Tuaka and Reteh. The families of Formicidae, Braconidae, Ichneumonidae, and Scelionidae had the highest number of species, while Formicidae, Scelionidae, Diapriidae, and Braconidae had the highest number of individuals. Based on these findings, the abundance and diversity of Hymenoptera insects in Indragiri Hilir District have the potentials to be developed as biological agents to control pests on tidal swamp rice in this area.

AbstractThe Malaise trap has gained popularity for assessing diverse terrestrial arthropod communities because it collects large samples with modest effort. A number of factors that influence collection efficiency, placement being one of them. For instance, when designing larger biotic surveys using arrays of Malaise traps we need to know the optimal distance between individual traps that maximises observable species richness and community composition. We examined the influence of spacing between Malaise traps by metabarcoding samples from two field experiments at a site in Waterloo, Ontario, Canada. For one experiment, we used two trap pairs deployed at weekly increasing distance (3m increments from 3 to 27 m). The second experiment involved a total of 10 traps set up in a row at 3m distance intervals for three consecutive weeks.Results show that community similarity of samples decreases over distance between traps. The amount of species shared between trap pairs shows drops considerably at about 15m trap-to-trap distance. This change can be observed across all major taxonomic groups and for two different habitat types (grassland and forest). Large numbers of OTUs found only once within samples cause rather large dissimilarity between distance pairs even at close proximity. This could be caused by a large number of transient species from adjacent habitat which arrive at the trap through passive transport, as well as capture of rare taxa, which end up in different traps by chance.

Abstract Insecticide application and augmentative parasitoid releases are often considered incompatible. However, pesticide applications and parasitoid releases can be integrated into a pest management scheme if there is careful time scheduling of these interventions. In this study, we assessed the influence of commonly used insecticides (chlorpyrifos-methyl, deltamethrin, pyriproxyfen, thiamethoxam) in olive agroecosystems to two currently present Trichogramma parasitoids in the Mediterranean basin. Exposure to insecticides in relation to parasitoid's development was also tested. Both, insecticide type and application time influenced parasitism and the emergence rates of the two parasitoid species. Chlorpyrifos-methyl had the strongest impact on parasitoids resulting in low numbers of emerged adults followed by deltamethrin. The two parasitoids also exhibited different levels of susceptibility to the insecticides used. Potential integration of insecticides to integrated pest management using Trichogramma parasitoids is discussed.

AbstractEcological investigations of long-legged flies (Dolichopodidae) were carried out in wet meadow wetlands near České Budějovice, Czech Republic. Sampling was performed during the adult flies’ seasonal activity (March–October) in 2002, 2003 and 2004 using yellow pan traps, Malaise traps, emergence traps, and by sweeping. Altogether 5,697 specimens of 78 species of Dolichopodidae were collected, identified and analysed. The study examined community structure, species abundance, and diversity (Shannon-Weaver’s index - H’; Sheldon’s equitability index - E). Chrysotus cilipes, C. gramineus and Dolichopus ungulatus were the most abundant species in all three years. Species richness and diversity seem strongly affected by soil moisture.

Several invertebrate surveys in Croatia conducted between 2005 and 2014 and including; e.g., Plitvice Lakes, produced 123 bycatch samples of Dolichopodidae (Diptera) from 68 sampling sites collected at 36 localities in seven counties. Seventy-seven were retrieved from emergence traps, six from pan traps and 40 were collected with sweep net and/or aspirator. They contained 420 dolichopodid flies that belonged to 64 species in 22 genera. Four species, Campsicnemus umbripennis, Hercostomus chetifer, Liancalus virens and Syntormon pallipes, accounted for over half of the yields. Contrary to most species that were found in largest numbers in rivers, and their beds in particular, S. pallipes and Hercostomus gracilis were considerably more abundant at springs. Fifty-five species could be added to the national checklist which raises the total number to 94 species. All species records are given, the habitat of each species is described, if possible, and taxonomic notes are provided for some dubious species. Finally, elements are presented to support the assumption that the extant dolichopodid species richness of Croatia is at least three- to fourfold of the current number.
