Abstract: This is the first report of two ectoparasitoid wasps, Elachertus inunctus (Nees, 1834) in Iran and Elachertus pulcher (Erdös, 1961) (Hym.: Eulophidae) in the world, that parasitize larvae of the tomato leaf miner, Tuta absoluta (Meyrick, 1917) (Lep.: Gelechiidae). The specimens were collected from tomato fields and greenhouses in Ahwaz, Khouzestan province (south west of Iran). Both species are new records for fauna of Iran. The knowledge about these parasitoids is still scanty. The potential of these parasitoids for biological control of T. absoluta in tomato fields and greenhouses should be investigated.

  • A Review of Sampling and Monitoring Methods for Beneficial Arthropods
    insects Review A Review of Sampling and Monitoring Methods for Beneficial Arthropods in Agroecosystems Kenneth W. McCravy Department of Biological Sciences, Western Illinois University, 1 University Circle, Macomb, IL 61455, USA; [email protected]; Tel.: +1-309-298-2160 Received: 12 September 2018; Accepted: 19 November 2018; Published: 23 November 2018 Abstract: Beneficial arthropods provide many important ecosystem services. In agroecosystems, pollination and control of crop pests provide benefits worth billions of dollars annually. Effective sampling and monitoring of these beneficial arthropods is essential for ensuring their short- and long-term viability and effectiveness. There are numerous methods available for sampling beneficial arthropods in a variety of habitats, and these methods can vary in efficiency and effectiveness. In this paper I review active and passive sampling methods for non-Apis bees and arthropod natural enemies of agricultural pests, including methods for sampling flying insects, arthropods on vegetation and in soil and litter environments, and estimation of predation and parasitism rates. Sample sizes, lethal sampling, and the potential usefulness of bycatch are also discussed. Keywords: sampling methodology; bee monitoring; beneficial arthropods; natural enemy monitoring; vane traps; Malaise traps; bowl traps; pitfall traps; insect netting; epigeic arthropod sampling 1. Introduction To sustainably use the Earth’s resources for our benefit, it is essential that we understand the ecology of human-altered systems and the organisms that inhabit them. Agroecosystems include agricultural activities plus living and nonliving components that interact with these activities in a variety of ways. Beneficial arthropods, such as pollinators of crops and natural enemies of arthropod pests and weeds, play important roles in the economic and ecological success of agroecosystems.

  • Crop Colonization by Pests and Specialist Enemies
    insects Article Dispersal in Host–Parasitoid Interactions: Crop Colonization by Pests and Specialist Enemies Edward W. Evans Department of Biology, Utah State University, Logan, UT 84322-5305, USA; [email protected]; Tel.: +01-435-797-2552 Received: 7 September 2018; Accepted: 2 October 2018; Published: 5 October 2018 Abstract: Interactions of insect pests and their natural enemies increasingly are being considered from a metapopulation perspective, with focus on movements of individuals among habitat patches (e.g., individual crop fields). Biological control may be undercut in short-lived crops as natural enemies lag behind the pests in colonizing newly created habitat. This hypothesis was tested by assessing parasitism of cereal leaf beetle (Oulema melanopus) and alfalfa weevil (Hypera postica) larvae at varying distances along transects into newly planted fields of small grains and alfalfa in northern Utah. The rate of parasitism of cereal leaf beetles and alfalfa weevils by their host-specific parasitoids (Tetrastichus julis (Eulophidae) and Bathyplectes curculionis (Ichneumonidae), respectively) was determined for earliest maturing first generation host larvae. Rates of parasitism did not vary significantly with increasing distance into a newly planted field (up to 250–700 m in individual experiments) from the nearest source field from which pest and parasitoid adults may have immigrated. These results indicate strong, rapid dispersal of the parasitoids in pursuing their prey into new habitat. Thus, across the fragmented agricultural landscape of northern Utah, neither the cereal leaf beetle nor the alfalfa weevil initially gained substantial spatial refuge from parasitism by more strongly dispersing than their natural enemies into newly created habitat.

  • The Entomofauna on Eucalyptus in Israel: a Review
    EUROPEAN JOURNAL OF ENTOMOLOGYENTOMOLOGY ISSN (online): 1802-8829 Eur. J. Entomol. 116: 450–460, 2019 http://www.eje.cz doi: 10.14411/eje.2019.046 REVIEW The entomofauna on Eucalyptus in Israel: A review ZVI MENDEL and ALEX PROTASOV Department of Entomology, Institute of Plant Protection, Agricultural Research Organization, The Volcani Center, Rishon LeTzion 7528809, Israel; e-mails: [email protected], [email protected] Key words. Eucalyptus, Israel, invasive species, native species, insect pests, natural enemies Abstract. The fi rst successful Eucalyptus stands were planted in Israel in 1884. This tree genus, particularly E. camaldulensis, now covers approximately 11,000 ha and constitutes nearly 4% of all planted ornamental trees. Here we review and discuss the information available about indigenous and invasive species of insects that develop on Eucalyptus trees in Israel and the natural enemies of specifi c exotic insects of this tree. Sixty-two phytophagous species are recorded on this tree of which approximately 60% are indigenous. The largest group are the sap feeders, including both indigenous and invasive species, which are mostly found on irrigated trees, or in wetlands. The second largest group are wood feeders, polyphagous Coleoptera that form the dominant native group, developing in dying or dead wood. Most of the seventeen parasitoids associated with the ten invasive Eucalyptus-specifi c species were introduced as biocontrol agents in classical biological control projects. None of the polyphagous species recorded on Eucalyptus pose any threat to this tree. The most noxious invasive specifi c pests, the gall wasps (Eulophidae) and bronze bug (Thaumastocoris peregrinus), are well controlled by introduced parasitoids.

  • Diversification, Selective Sweep, and Body Size in the Invasive Palearctic
    www.nature.com/scientificreports OPEN Diversifcation, selective sweep, and body size in the invasive Palearctic alfalfa weevil infected with Wolbachia Midori Tuda1,2,12*, Shun‑ichiro Iwase1,11,12, Khadim Kébé3,12, Julien Haran4,12, Jiri Skuhrovec5,12, Ehsan Sanaei6, Naomichi Tsuji7, Attila Podlussány8, Ottó Merkl8, Ahmed H. El‑Heneidy9 & Katsura Morimoto10 The alfalfa weevil Hypera postica, native to the Western Palearctic, is an invasive legume pest with two divergent mitochondrial clades in its invading regions, the Western clade and the Eastern/Egyptian clade. However, knowledge regarding the native populations is limited. The Western clade is infected with the endosymbiotic bacteria Wolbachia that cause cytoplasmic incompatibility in host weevils. Our aim was to elucidate the spatial genetic structure of this insect and the efect of Wolbachia on its population diversity. We analyzed two mitochondrial and two nuclear genes of the weevil from its native ranges. The Western clade was distributed in western/central Europe, whereas the Eastern/ Egyptian clade was distributed from the Mediterranean basin to central Asia. Intermediate mitotypes were found from the Balkans to central Asia. Most Western clade individuals in western Europe were infected with an identical Wolbachia strain. Mitochondrial genetic diversity of the infected individuals was minimal. The infected clades demonstrated a higher nonsynonymous/synonymous substitution rate ratio than the uninfected clades, suggesting a higher fxation of nonsynonymous mutations due to a selective sweep by Wolbachia. Trans‑Mediterranean and within‑European dispersal routes were supported. We suggest that the ancestral populations diversifed by geographic isolation due to glaciations and that the diversity was reduced in the west by a recent Wolbachia‑driven sweep(s).

The grub incidence was reported from 28-39th SMW. Simultaneously, random samples of mined leaves were collected from the surveyed plots, brought to the laboratory, examined for field parasitism symptoms, maintained and reared for further investigations, re- covered the association of hispa grubs or pupae with a gregarious parasitoid, which was identified as Chrysonotomyia sp. (Hymenoptera: Eulophidae: Entedoninae). Also, the maximum parasitization rates for this vary species of parasitoid were recorded during 34-39th SMW, with the mean parasitization of 46.0 and 39.3 percent during kharif 2015 and 2016, respectively. The natural parasitization of grubs or pupae of rice hispa by Chrysonotomyia sp. was reported for the first time from the state and it thus could be exploited as an important biological tool under the sustainable approach for its integrated management.
