The present account reviews some of the progress made recently towards understanding better the processing of visual information in the peripheral visual system of insects. To limit the scope, it
PHYLOGENY OF THE SUBFAMILIES OF THE FAMILY BRACONIDAE (HYMENOPTERA: ICHNEUMONOIDEA): A REASSESSMENT
Abstract— The recently published phylogeny of Braconidae by Quicke and van Achterberg is reassessed. Character‐state definitions and character polarities are evaluated, and more rigorous methods are
Evolution of the parasitic wasp subfamily Rogadinae (Braconidae): phylogeny and evolution of lepidopteran host ranges and mummy characteristics
TLDR
The molecular dating of clades and the ancestral reconstruction of host ranges support the hypothesis that radiation within Aleiodes s.
Phylogeny and biogeography of the parasitoid wasp family Megalyridae (Hymenoptera).
  • S. Shaw
  • Geography, Biology
  • 1 November 1990
TLDR
The family Megalyridae is postulated to have originated on Pangaea, possibly as early as the late Triassic, and a revised tribal classification for the megalyrids is proposed.
New, native species of Peristenus (Hymenoptera : Braconidae) parasitizing Lygus hesperus (Hemiptera : Miridae) in Idaho : Biology, importance, and description
TLDR
It is found that P. howardi is a native species, is thelyotokous, has three generations per year, and produces some diapausing parasites in each generation, so it is also a potential biocontrol agent for this related mirid species.
Carminator, a new genus of Megalyridae (Hymenoptera) from the Oriental and Australian regions, with a commentary on the definition of the family
TLDR
The taxonomic history of the family Megalyridae is reviewed and four new species are included in the genus Carminator, including two new species from the Oriental and Australian regions.
Minimalist revision and description of 403 new species in 11 subfamilies of Costa Rican braconid parasitoid wasps, including host records for 219 species
TLDR
Three new genera are described: Michener (Proteropinae), Bioalfa ( Rogadinae) and Hermosomastax (Rogadinaes) and a consensus sequence of the COI barcodes possessed by each species is employed to diagnose the species, and this approach is justified in the introduction.
DIFFERENTIAL PARASITISM OF MACROLEPIDOPTERAN HERBIVORES ON TWO DECIDUOUS TREE SPECIES
TLDR
Comparisons of parasitism levels among lepidopteran families showed that in five of seven families larval parasitism on box elder was significantly higher than on black willow and the roles of the functional/numerical responses of parasitoids, common and numerically dominant parasitoid species, and plant volatiles are considered but are not supported by the data.
Decremental conduction of the visual signal in barnacle lateral eye
  • S. Shaw
  • Biology
    The Journal of physiology
  • 1972
TLDR
The idea that slow potentials alone are used to transmit information in the early stages of some visual systems and alternatives have been tested on the barnacle lateral ocellus, a simple eye with only three photoreceptors.
Circadian rhythms in light-evoked responses of the fly's compound eye, and the effects of neuromodulators 5-HT and the peptide PDF
TLDR
Two sets of wide-field neurons extend neurites into the fly's optic lamina, where monopolar cells receive photoreceptor input, and re-examined the electroretinogram for circadian rhythmicity, and for responses to locally injected 5-hydroxytryptamine and peptide.
