The potato tuber moth, Phthorimaea operculella (Zeller) is one of the most destructive pest of potatoes. Also, we found this species attacking the diamondback moth, Plutella xylostella (Lepidoptera: Plutellidae). Ratio of para- sitism is 20-30% and cocoon of lepidopteran was parasitic ichneumonid species after 3 days. This species and the genus Diadegma are recorded for the first time from Korea. In this paper, description of the parasitoid and photographs of the diagnostic characteristics are provided.

  • ELIZABETH LOCKARD SKILLEN Diversity of Parasitic Hymenoptera
    ELIZABETH LOCKARD SKILLEN Diversity of Parasitic Hymenoptera (Ichneumonidae: Campopleginae and Ichneumoninae) in Great Smoky Mountains National Park and Eastern North American Forests (Under the direction of JOHN PICKERING) I examined species richness and composition of Campopleginae and Ichneumoninae (Hymenoptera: Ichneumonidae) parasitoids in cut and uncut forests and before and after fire in Great Smoky Mountains National Park, Tennessee (GSMNP). I also compared alpha and beta diversity along a latitudinal gradient in Eastern North America with sites in Ontario, Maryland, Georgia, and Florida. Between 1997- 2000, I ran insect Malaise traps at 6 sites in two habitats in GSMNP. Sites include 2 old-growth mesic coves (Porters Creek and Ramsay Cascades), 2 second-growth mesic coves (Meigs Post Prong and Fish Camp Prong) and 2 xeric ridges (Lynn Hollow East and West) in GSMNP. I identified 307 species (9,716 individuals): 165 campoplegine species (3,273 individuals) and a minimum of 142 ichneumonine species (6,443 individuals) from 6 sites in GSMNP. The results show the importance of habitat differences when examining ichneumonid species richness at landscape scales. I report higher richness for both subfamilies combined in the xeric ridge sites (Lynn Hollow West (114) and Lynn Hollow East (112)) than previously reported peaks at mid-latitudes, in Maryland (103), and lower than Maryland for the two cove sites (Porters Creek, 90 and Ramsay Cascades, 88). These subfamilies appear to have largely recovered 70+ years after clear-cutting, yet Campopleginae may be more susceptible to logging disturbance. Campopleginae had higher species richness in old-growth coves and a 66% overlap in species composition between previously cut and uncut coves.

  • Is Diadegma Insulare Or Microplitis Plutellae a More Effective Parasitoid of the Diamondback Moth, Plutella Xylostella ?
    War of the Wasps: Is Diadegma insulare or Microplitis plutellae a More Effective Parasitoid of the Diamondback Moth, Plutella xylostella ? ADAMO YOUNG 108 Homestead Street, Ottawa Ontario K2E 7N6 Canada; email: [email protected] Young, Adamo. 2013. War of the wasps: is Diadegma insulare or Microplitis plutellae a more effective parasitoid of the Dia - mondback Moth, Plutella xylostella ? Canadian Field-Naturalist 127(3): 211–215. Parasitism levels by Diadegma insulare (Muesebeck) (Hymenoptera: Ichneumonidae) and Microplitis plutellae (Haliday) (Hymenoptera: Braconidae) at various densities of their host, Plutella xylostella (L.) (Lepidoptera: Plutellidae), were assessed. Cages with densities of 10 hosts, 20 hosts, and 40 hosts were set up, with the cage volume (40 500 cm 3) and number of wasps (2 females) remaining constant. The host populations were also exposed to the wasps for two different exposure times: 1 day and 3 days. The study showed that D. insulare was a better parasitoid overall, achieving a level of parasitism equal to or higher than M. plutellae at all densities. Microplitis plutellae performed best at a lower host density (76% ± 9% of 10 hosts vs. 43% ± 3% of 40 hosts). Diadegma insulare performed similarly at all densities tested (75% ± 5% of 10 hosts, 83% ± 4% of 20 hosts, and 79% ± 6% of 40 hosts). This suggests that D. insulare may be the better parasitoid overall and should be applied in severe, large-scale infestations, while M. plutellae may be better for small-scale infestations. Key Words: Diamondback Moth; Plutella xylostella; Microplitis plutellae; Diadegma insulare; parasitoids; biological control Introduction ical control can provide better control than pesticides.

R. China (Received Dec. 9 , 2002 ; accepted Mar. 27 , 2003) Abstract In haplodiploid Hymenoptera , unfertilized eggs produce haploid males while fertilized eggs lead to diploid females under most circumstances. Diploid males can also be produced from fertilization under a system of sex determination known as complementary sex determination (CSD) . Under single2locus CSD , sex is determined by multiple alleles at a single sex locus. Individuals heterozygous at the sex locus are female while hemizygous and homozygous individuals develop as haploid and diploid males , respectively. In multiple2locus CSD , two or more loci , each with two or more alleles , determine sex. Diploid individuals are female if one or more sex loci are het 2 erozygous , while a diploid is male only if homozygous at all sex loci. Diploid males are known to occur in 43 hym2 enopteran species and single2locus CSD has been demonstrated in 22 of these species. Diploid males are either developmentally inviable or sterile , so their production constitutes a genetic load. Because diploid male production is more likely under inbreeding , CSD is a form of inbreeding depression.

  • Ichneumon Sub-Families This Page Describes the Different Sub-Families of the Ichneumonidae
    Ichneumon Sub-families This page describes the different sub-families of the Ichneumonidae. Their ecology and life histories are summarised, with references to more detailed articles or books. Yorkshire species from each group can be found in the Yorkshire checklist. An asterix indicates that a foreign-language key has been translated into English. One method by which the caterpillars of moths and sawflies which are the hosts of these insects attempt to prevent parasitism is for them to hide under leaves during the day and emerge to feed at night. A number of ichneumonoids, spread through several subfamilies of both ichneumons and braconids, exploit this resource by hunting at night. Most ichneumonoids are blackish, which makes them less obvious to predators, but colour is not important in the dark and many of these nocturnal ones have lost the melanin that provides the dark colour, so they are pale orange. They have often developed the large-eyed, yellowish-orange appearance typical of these nocturnal hunters and individuals are often attracted to light. This key to British species is a draft: http://www.nhm.ac.uk/resources-rx/files/keys-for-nocturnal-workshop-reduced-109651.pdf Subfamily Pimplinae. The insects in this subfamily are all elongate and range from robust, heavily- sculptured ichneumons to slender, smooth-bodied ones. Many of them have the 'normal' parasitoid life-cycle (eggs laid in or on the host larvae, feeding on the hosts' fat bodies until they are full- grown and then killing and consuming the hosts) but there are also some variations within this subfamily.

As parasitoids, they fulfil a vital role as regulators in terrestrial ecosystems. However, we still know too little about their diversity and ecology to fully appreciate the ecosystem services they provide and to unleash their full potential as biological control agents. If you would like to help pushing back the frontier of ignorance in Darwin wasps, take a look at the suggested topics for master theses below. If interested also in fossil insects, visit the web page of Alexandra Viertler for more ideas (www.nmbs.ch/home/museum/team/Alexandra-Viertler.html). Evolution of host relations in Campopleginae parasitoid wasps Many parasitoid wasps show extraordinary adaptations to attacking a particular group of insect hosts. This is especially true for the subfamily Campopleginae, members of which have adopted a virus into their genome, which they inject into the host together with the egg in order to use it as a weapon against their host’s immune system. Different genera of Campopleginae attack insects in four different orders: Lepidoptera (butterflies and moths), Hymenoptera: Symphyta (sawflies), Coleoptera (beetles) and Raphidioptera (snakeflies). In this project, you will compile a molecular dataset to reconstruct the tree of life of Campopleginae and use it to analyse how many times, when, and in which directions these drastic host switches took place, and whether the virus weaponry was retained or lost in their wake. Unravelling an alpine diversity hotspot – searching for new species on Alp Flix If you thought that new species can only be found in tropical rain forests, think again! Another hotspot of undiscovered diversity lies at our doorsteps: the Alps.

Reproductive biology of Diadegma semiclausum Hellen (Hymenoptera: Ichneumonidae) A thesis submitted in partial fulfilment of the requirements for the degree of Master of Science (MSc) in Plant Protection at Massey University Palmerston North, New Zealand Diwas Khatri 2011 Abstract The ichneumonid Diadegma semiclausum Hellen has been recorded in many parts of the world as an important parasitoid of diamondback moth, Plutella xylostella (Linnaeus), a serious pest of brassica vegetable crops worldwide. Some aspects of reproductive biology were studied in controlled laboratory conditions of 21±1°C, 16:8 h (light:dark) and 50-60% RH. Diadegma semiclausum adults emerge only during the photophase. It has a protandrous emergence pattern because the male developmental time is shorter than the female. Most males emerge in the first half of the photophase whereas females emerge during the second half. Both males and females become sexually mature in <12 h after emergence. When paired with 3-d-old virgin mates, more newly emerged females (<12-h-old) mate, compared to newly emerged males. Females, immediately after eclosion (<1-h-old), do not carry mature eggs in their ovaries, and hence this is a strong synovigenic species. Maternal age affects the egg load, which reaches the maximum by 8 d after emergence. Egg resorption occurs in host deprived females and the number of mature eggs declines with age when >20 d.
