Resumen. Se describe el primer registro de caza para Sphictostethus striatulus Roig-Alsina, 1987. En el presente reporte, el pompílido caza un ejemplar de Tomopisthes horrendus (Nicolet, 1849). Las observaciones fueron registradas en la Región de Los Lagos, Chile. Se incluyen ilustraciones y se discute el registro. Abstract. The first hunting record of Sphictostethus striatulus Roig-Alsina, 1987, over Tomopisthes horrendus (Nicolet, 1849) is reported. The record is based on observations made in Los Lagos Region, Chile. Illustrations are provided and the interaction is briefly discussed.

Carob moth, Ectomyelois ceratoniae (Lepidoptera: Pyralidae) is the most important pest of pomegranate, Punica granatum (Punicaceae), in Iran. The most recommended procedure to control of this pest is collecting and destroying infested fruits in the orchards at the end of cropping season to eliminate overwintering sites. In order to determine the parasitoid species and the parasitism percentage during fall-winter season (2006e2007) a study was conducted in three commercial pomegranate orchards in Varamin, Qom, and Saveh, (central Iran). Our results revealed that E. ceratoniae had numerous parasitoids from the families Braconidae and Ichneumonidae. Apanteles myeloenta Wilkinson (Hymenoptera: Braconidae) was the most prevalent species among the collected parasitoids in all studied sites. More parasitoids were found in fruits on trees than those on the ground. Fruits on the ground were more infested than fruits on trees. According to our results collecting and destroying the infected fruits in the orchards at the end of cropping season, had negative effects on parasitoids population and diversity.

Brachycyrtus cosmetus (Hymenoptera, Ichneumonidae, Brachycyrtinae) is reported for the first time in Panama. The specimen corresponds to a male emerged from a pupa of Chrysopidae (Neuroptera), collected from leaves of Ficus benjamina (Moraceae). A brief description is provided with the habitat where the specimen was collected, along with pictures of the species.

Nasonia (Hymenoptera: Pteromalidae) is a genus of parasitoid wasps, which is fast emerging as a model system for evolutionary, genetic, developmental and host-endosymbiont interaction studies. In this study, we report a new species, Nasonia oneida, distinguish its behavioral, genetic and morphological features, and characterize its pre-mating and post-mating isolation with the other Nasonia species. Phylogenetic analyses indicate that N. oneida is the sister species to Nasonia giraulti with its own uniquely distinct cuticular hydrocarbon profiles, behavioral characteristics and subtle morphological differences. An important characteristic of N. oneida is the strong mate discrimination shown by the females against all the other Nasonia species. A genetic analysis of this phenotype by interspecies hybridization indicates that this strong discriminating phenotype is recessive. A formal species description of N. oneida Raychoudhury & Desjardins is also provided.

1. The reproductive fitness of a parasitoid depends on its mating and ovipositing success. Virgin haplodiploid females can reproduce, but produce only males, and may diminish fitness by producing more male offspring than required. Therefore, females must decide on whether to mate or oviposit first.2. This study was conducted to assess the mating versus ovipositing decision and its impact on the reproductive fitness of Diaeretiella rapae (Hymenoptera: Aphididae), an endoparasitoid of the cabbage aphid Brevicoryne brassicae (Hemiptera: Aphididae).3. When newly emerged females were given a choice between mating and ovipositing, about 62% of D. rapae females preferred to mate before ovipositing. Those females who oviposited before mating parasitised only 10% of the available aphids. After mating, females superparasitised their hosts with fertilised eggs, which resulted in a highly female-biased sex ratio in the offspring.4. Mating success was very high (91%) in the presence of hosts (cabbage aphid nymphs) compared with that in the absence of aphids. However, mating success was not influenced by the quality (size) of the hosts present in the mating arena, despite a parasitoid preference for larger hosts during oviposition. The time between pairing and mating was also shorter in the presence of host aphids. The mean number of aphids parasitised and the parasitism rate were significantly greater after mating.

The parasitoid wasp Clistopyga melanoptera Cas-tillo, Sääksjärvi & Bordera, 2016 was described recently and was known only from the type locality, Cusco, Peru. Here we provide a first record of this species for Brazil, at Manaus, 1700 km... more
