TL;DR: Three new species groups and seven species of the genus Pediobius Walker are described from the Afrotropical realm and the comparison of the new species with similar taxa of Entedoninae suggested the following synonymies.
Abstract: Three new species groups and seven species of the genus Pediobius Walker are described from the Afrotropical realm: the marjoriae group, with P. marjoriae Kerrich (described from Uganda), P. rohombaya Gumovsky sp. n. (from the Central African Republic (CAR), the Democratic Republic of the Congo (DRC), Gabon, Uganda) and P. orungu Gumovsky sp. n. (from Gabon); the afroteres group with P. afroteres Gumovsky sp. n. (from South Africa, Zimbabwe, Malawi, Kenya, Uganda, DRC, Cameroon) and P. kafroteres Gumovsky sp. n. (from Cameroon); the askari group with P. askari Gumovsky sp. n. (from South Africa, Zimbabwe, Kenya, Tanzania, DRC, Ivory Coast) and P. maleficus Gumovsky sp. n. (from Kenya, DRC, CAR, Cameroon, Gabon); and P. nganga Gumovsky sp. n. (from DRC) (not assigned to any group). All these species are characterized by the relatively wide and robust head with elongate and/or narrowed lower face and the antennae attached near or below the lower eye margins. Morphological features of the species, as well as their habitat distribution, are discussed. The comparison of the new species with similar taxa of Entedoninae suggested the following synonymies: Rhynchentedon Girault and Pediobomyia Girault under Pediobius (syn. n.); Bomyiabius frontus Narendran, Pediobomyia budaicus Narendran and Pediobomyia lankicus Narendran under Pediobomyia darwini Girault (syn. n.). The following new combinations are proposed: Pediobius maximus (Girault), P. achterbergi (Gumovsky), P. narendrani (Gumovsky), P. brevicaulis (Hansson), P. canaliculatus (Hansson) and P. darwini (Girault) (comb. n.). Ant parasitoids P. marjoriae and Myrmokata diparoides Boucek are recorded from DRC for the first time.

TL;DR: It is confirmed that overlapping generations were vital for the persistence of parasitoids of M. plana and the paper suggested a possible need of alternative hosts.

TL;DR: A wide range of egg, larval and pupal parasitoids of stemborers have been identified, but information on predators, nematodes and microbial pathogens is less extensive.
Abstract: The noctuids Busseola fusca and Sesamia calamistis and the pyraloids Chilo partellus, Chilo orichalcociliellus and Eldana saccharina are the most important stemborers of maize in East Africa. A wide range of egg, larval and pupal parasitoids of stemborers have been identified, but information on predators, nematodes and microbial pathogens is less extensive. The most abundant and widespread parasitoids in the East African region are the egg parasitoids Telenomus spp. and Trichogramma spp., the larval parasitoids Cotesia sesamiae and Sturmiopsis parasitica and the pupal parasitoids Pediobius furvus and Dentichasmias busseolae. Predators, such as ants, spiders and earwigs can cause high mortality of eggs and young larvae in some areas. Nematodes and microbial pathogens have been reported to infect all life stages, but their impact is low under natural conditions. The abundance of natural enemies can vary considerably between locations and seasons. In general, indigenous natural enemies are not able to keep stemborer populations below economic injury levels. This paper summarises what is currently known of the natural enemies of cereal stemborers in East Africa.

TL;DR: The light brown apple moth, Epiphyas postvittana (Walker), an Australia native tortricid, was found in California in 2006 and the potential for resident parasitoid species to suppress E. postVittana populations is discussed.
Abstract: The light brown apple moth, Epiphyas postvittana (Walker), an Australia native tortricid, was found in California in 2006. A field survey of host plants used by E. postvittana was conducted in an urban region of the San Francisco Bay Area. An inspection of 152 plant species (66 families), within a 23-ha residential community, found E. postvittana on 75 species (36 families). Most (69 species) host plants were not Australian natives, but had a wide geographic origin; 34 species were new host records for E. postvittana. Heavily infested species were the ornamental shrubs Myrtus communis L., Pittosporum tobira (Thunb.) W.T. Aiton, Euonymus japonicus Thunb., and Sollya heterophylla Lindl. To survey for parasitoids, four urban locations were sampled, with E. postvittana collected from five commonly infested plants [M. communis, P. tobira, E. japonicus, Rosmarinus officinalis L., and Genista monspessulana (L.) L.A.S. Johnson]. Twelve primary parasitoid species and two hyperparasitoids were reared; the most common were the egg parasitoid Trichogramma fasciatum (Perkins), the larval parasitoids Meteorus ictericus Nees, and Enytus eureka (Ashmead), and the pupal parasitoid Pediobius ni Peck. Meteorus ictericus accounted for >80% of the larval parasitoids, and was recovered from larvae collected on 39 plant species. Across all samples, mean parasitism was 84.4% for eggs, 43.6% for larvae, and 57.5% for pupae. The results are discussed with respect to the potential for resident parasitoid species to suppress E. postvittana populations.

TL;DR: A parasite of agromyzid leaf miners, mainly of Liriomyza sativae Blanch, in the West Indies, and Emersonella palmae sp.
Abstract: Chrysocharis caribea sp. n., a parasite of agromyzid leaf miners, mainly of Liriomyza sativae Blanch, in the West Indies, and Emersonella palmae sp. n., parasite of Hispoleptis subfasciata Pic, a hispine leaf miner on oil palms in Colombia, are described. New generic and specific synonymies and new combinations are established in Chrysocharis Forster, Proacrias Ihering (= Didymotropis De Santis syn. n.), Chrysonotomyia Ashmead (= Achrysocharis Girault syn. n.), Teleopterus Silvestri, Pediobius Walker, Emersonella Girault, Euplectrus Westwood, Stenomesius West-wood, Diglyphomorpha Ashmead, Miotropis Thomson, Ardalus Howard and Grotiusomyia Girault. Additional taxonomic comments on Chrysocharodes Ashmead and Astichus Forster and tentative keys to the species of Proacrias and Emersonella are included. Lectotypes are designated for 24 specific names.
