Electrophoretic Discrimination of Species of the Muscidifurax (Hymenoptera: Pteromalidae) Complex
The systematics of Muscidifurax (Hymenoptera: Pteromalidae), a parasitoid of the housefly, has been studied using gel electrophoresis of enzymes. Electrophoretic techniques have been perfected for the genetic analysis of Muscidifurax. These methods reveal "fixed" genetic differences between …

The genetics of species differences within the genus Nasonia ASHMEAD 1904 (Hymenoptera: Pteromalidae)
The genetics of species differences is an outstanding question in evolutionary biology. How do species evolve to become phenotypically distinct and how is the genetic architecture organized that underlie species differences? Phenotypic diverged traits are supposed to be frequently involved in …

The impact of Tomicobia tibialis (Hymenoptera : pteromalidae) on the pine engraver, Ips pini (Coleoptera : scolytidae)
Augmentative release of biological control agents against pest insects is a management tool that has been largely ignored in forestry due to a lack of understanding and means of producing potential agents. I investigated the effects of Tomicobia tibialis Ashmead on the reproductive potential of …

The Sphegigasterini: A Cladistic Analysis and Generic Classification With Reviews of Selected Genera (Hymenoptera: Pteromalidae)
The Sphegigasterini sensu strictu (Boucek, 1988) is defined by the possession of a basal flange on the petiole. The history of the genera belonging to the Sphegigasterini sensu strictu is reviewed. The author's intuitive classification of the genera is given.

Assessment of Parasitism of House Fly and Stable Fly Pupae (Diptera: Muscidae) by Pteromalid (Hymenoptera: Pteromalidae) Parasitoids Using Polymerase Chain Reaction (Pcr)
Three puparia collected in 1997 produced double bands prior to digestion of the PCR product by a restriction enzyme. The sizes of the bands corresponded to the sizes produced by amplification of the DNA of Muscidifurax and Spalangia species, possibly indicating hyperparasitism. Comparison of …

Evaluation of the potential of Pteromalus puparum (L.) (Hymenoptera: Pteromalidae) for suppression of the imported cabbageworm and parasitism of the diamondback moth
… <i>Pteromalus puparum</i> (L.) (Hymenoptera: Pteromalidae) parasitized 64.1% and 32.5% of imported cabbageworm pupae in 1983 and 1984; parasitism was most pronounced in the latter part of the season. High percentages of parasites successfully emerged as adults, indicating efficient host …

Phylogeny and codivergence in the fig-fig wasp mutualism : sycoecine and agaondid fig wasps (Chalcidoidea, Hymenoptera) associated with Ficus section Galoglychia (Moraceae)
… and sycoecine non-pollinating fig wasps (Pteromalidae, Chalcidoidea, Hymenoptera) through cophylogenetic analysis.

Calidad fitosanitaria y presencia de aflatoxinas en granos de sorgo (Sorghum bicolor (L.) Moench), en almacen y campo, 2005
… sp. y parasitoides de la familia Bethylidae y Pteromalidae. A nivel de campo el insecto que se encontró con mayor número fue el telarañero del sorgo ( Celama sp). Los géneros de hongos Fusarium spp, Helminthosporium sp. y la bacteria Pseudomonas syringae ocasionaron los más altos porcentajes de …

Host-Parasitoid Interactions of Two Invasive Drosophilids in Virginia Fruit Crops
… vindemiae (Rondani) (Hymenoptera: Pteromalidae), were reared, but only one P. vindemiae was reared from D. suzukii, and no parasitoids were reared from Z. indianus. Most parasitoids were reared from alternate host Drosophila melanogaster Meigen and other wild drosophilids. 2.) The …

Why do wasp induced galls of Acacia longifolia photosynthesise?
… by the wasp, Trichilogaster acaciae longifoliae (Pteromalidae) in the invasive Acacia longifolia. The role of this photosynthetic activity was examined in terms of its ability to subsidise carbon budgets, as well as to provide O₂ to the larvae and consume CO₂ in the dense gall tissue, thereby …

Impact of the microbial pesticide Bacillus thruingiensis Berliner subsp. kurstaki on Hymenopterous parasites of the imported cabbageworm, Pieris rapae (L.) (Lepidoptera: Pieridae)
… parasite Pteromalus puparum (L.) (Hyrnenoptera: Pteromalidae) continued after spraying in the B. thuringiensis plots, but was not significantly different from perrnethrin. However, 100% of the P. rapae chrysalids recovered were parasitized by P. puparum. The impact of seasonal hyperparasitism was …

Bio-ecological studies of Tuta absoluta in Sudan
… sp. (Eupelmidae), and two species belonging to Pteromalidae and Ichneumonidae families. The predators found were Nesidiocoris tenuis (Nesibug) (Miridae) and Chrysoperla sp. (Chrysopidae). Infestation of T. absoluta appears approximately two months after seeding of tomato and eggplant during the …

Insects in mountainous landscapes: Implications of landscape context and climate change
… its parasitoid Gastrancistrus sp. (Hymenoptera: Pteromalidae). Habitat suitability and patch-level extinctions and (re)colonisations (i.e., population dynamics) for both herbivores, T. obscura abundance, and gall midge-parasitoid proportions were predicted with generalized linear models, applying …

Compatibility of biological and cultural control in dairy heifer group housing
The compatibility of biological and cultural fly control on dairies was examined in three ways. First, a review of the current literature concerning filth fly production and filth fly pupal parasitoids on dairies was conducted to asses where there was a lack of information. Second, a survey of …
