    Biodiversity of the natural enemies of aphids (Hemiptera: Aphididae) in Northwest Turkey
    (Springer, 2020) Kok, Sahin; Tomanovic, Zeljko; Nedeljkovic, Zorica; Senal, Derya; Kasap, Ismail
    In the present study, the natural enemies of aphids (Hemiptera: Aphididae) and their host plants including herbaceous plants, shrubs and trees were analysed to reveal their biodiversity and disclose tritrophic associations in different habitats of the South Marmara region of northwest Turkey. As a result of field surveys, 58 natural enemy species associated with 43 aphids on 58 different host plants were identified in the region between March of 2017 and November of 2018. In 173 tritrophic natural enemy-aphid-host plant interactions including association records new for Europe and Turkey, there were 21 representatives of the family Coccinellidae (Coleoptera), 14 of the family Syrphidae (Diptera) and 15 of the subfamily Aphidiinae (Hymenoptera), as well as eight other generalist natural enemies. In these interactions, a total of 37 aphid-natural enemy associations-including 19 associations of Acyrthosiphon pisum (Harris) with natural enemies, 16 associations of Therioaphis trifolii (Monell) with natural enemies and two associations of Aphis craccivora Koch with natural enemies-were detected on Medicago sativa L. during the sampling period. Similarly, 12 associations of Myzus cerasi (Fabricius) with natural enemies were revealed on Prunus avium (L.), along with five associations of Brevicoryne brassicae (Linnaeus) with natural enemies (including mostly parasitoid individuals) on Brassica oleracea L. Also in the study, reduviids of the species Zelus renardii (Kolenati) are reported for the first time as new potential aphid biocontrol agents in Turkey. The results of field surveys show that the natural enemies of aphids have high biodiversity, which should be considered in the management of biological pest control.

    Diversity and interactions of the parasitoids (Hymenoptera: Braconidae: Aphidiinae) of aphids from a lagoon habitat in northwest Turkey
    (Springer, 2022) Kok, Sahin; Tomanovic, Zeljko
    The aim of this study was to reveal the diversity of parasitoids and ascertain tritrophic parasitoid-host aphid-host plant interactions in a lagoon habitat very close to orchards, vegetable gardens, and cereal fields in the canakkale Province of northwest Turkey between April and September from 2020 to 2021. In total, 23 tritrophic parasitoid-host aphid-host plant interactions, including new association records for Europe and Turkey, were revealed on 12 parasitoid species belonging to six genera from the subfamily Aphidiinae (Hymenoptera: Braconidae) reared from 15 aphid species (Hemiptera: Aphididae) on 17 host plants from different plant families. Also, we present three tritrophic parasitoid-host aphid-host plant interactions new for Europe and five tritrophic interactions new for Turkey. Of the identified parasitoid species, Aphidius (Aphidius) artemisicola Tizado et Nunez-Perez, 1994 is recorded for the first time for the parasitoid fauna of Turkey. A morphological diagnosis of the newly recorded parasitoid is provided. The results of this study of the tritrophic interactions between parasitoids and their aphid hosts on host plants in a lagoon habitat enable us to more meaningfully interpret these interactions and provide data of potential significance for the biological control of pest aphids in the region. These results showed that research on the interactions of parasitoids and their host aphids on non-crop host plants in non-crop areas close to crop fields can yield data of potential significance for the biological control of aphids in agriculture.
