Nine parasitoids of the moth genus Heterogynis are presented: six species of Hymenoptera from the families Chalcididae, Eulophidae and Ichneumonidae (Agrothereutes hospes (Tschek), Baryscapus endemus (Walker), Brachymeria inermis (Fonscolombe), Diplazon laetatorius (F.), Itoplectis maculator (F.) and Trichomalopsis heterogynidis Graham), and three Diptera, family Tachinidae (Compsilura concinnata (Meigen), Exorista segregata (Rondani) and Phryxe hirta (Bigot)). Two of these species, Trichomalopsis heterogynidis and Phryxe hirta, are oligophagous parasitoids specialized on the genus Heterogynis. We also identified two newly recorded parasitoids of Heterogynis: Brachymeria inermis (Chalcididae) and Diplazon laetatorius (Ichneumonidae).

Population variations of predatory hoverflies in agroecosystems depend mainly on the resources that crops and wild vegetation provides them as well as death caused by natural enemies. We identified I) aphidophagous hoverfly species in lettuce and broccoli crops in Buenos Aires, II) the seasonal variations of the immature stages and their larval parasitism, and III) the wild plants, surrounding the crops, visited by adults. Fortnightly, 30 leaves were randomly selected in both crops during 2018-2019 and immature stages of syrphids and aphids per leaf were recorded. Adults were manually collected in patches of the wild plants (during 10 min of direct observations), and plants visited by adults were determined. The hoverflies were Allograpta exotica Wiedemann and Toxomerus duplicatus Wiedemann. Only A. exotica was recorded in crops. The dominant aphids were Myzus persicae (Sulzer) in lettuce and Brevycorine brassicae (L.) in broccoli. Parasitism rates ranged between 8 and 100% and the species were Diplazon laetatorius (Fabricius), in both crops, and Pachyneuron aff. nelsoni only in broccoli. Galinsoga parviflora Cav. and Matricaria chamomilla L. were the wild plants most often visited by hoverflies. This work provides basic information for the control of aphids by hoverflies in the framework of conservation biological control

AbstractSeveral parasites were surveyed for their ability to develop to pupation in virus-infected hosts. The tachinid Compsilura concinnata (Meigen), the ichneumonids Campoletis sonorensis (Cameron) and Hyposoter exiguae (Viereck), and the braconid Cotesia marginiventris (Cresson) developed to pupation in the armyworm, Pseudaletia unipuncta (Haworth), infected with either the Hawaiian strain of granulosis virus (HGV) or the hypertrophy strain of nuclear polyhedrosis virus (HNPV). The braconid Chelonus insularis Cresson died after its HGV- or HNPV-infected host P. unipuncta died. On the other hand, the braconid Glyptapanteles militaris (Walsh) died in HNPV-infected P. unipuncta before the host died. Some of these parasites had tissues that were melanized and some were encapsulated by the host. The ichneumonid H. exiguae and the braconids Chelonus insularis and Cotesia marginiventris developed to pupation in HGV-infected Spodoptera exigua (Hübner). In some cases, developmental time of parasites in virus-infected hosts was longer than in control hosts.
