Insects Parasitoids: Natural Enemies of Helicoverpa
Queensland the Smart State insects Parasitoids: Natural enemies of helicoverpa Introduction Helicoverpa caterpillars (often called heliothis) are serious pests of many crops in Australia. A range of parasitoid and predatory insects attack helicoverpa. Identifying and conserving these beneficial insects is fundamental to implementing pest management with a reduced reliance on chemical insecticides. This brochure describes the most important parasitoids of helicoverpa in Australian broadacre crops. Parasitoids versus parasites: What’s the difference? Parasitoids kill their hosts; parasites (such Figure 1. Netelia producta is one of the as lice and fleas) do not. All the insects most commonly encountered parasitoids in this brochure are parasitoids. Despite of helicoverpa. Females lay their eggs onto this difference, the terms parasitoid and caterpillars, and the hatching wasp larva parasite are often used interchangeably, if feeds on its host, eventually killing it. inaccurately. Parasitoids such as Netelia can be important biological control agents of helicoverpa in crops. (Photo: K.

Breeding Strategies in Females of the Parasitoid Wasp Spalangia Endius: Effects of Mating Status and Size
P1: VENDOR/GXB Journal of Insect Behavior [joib] pp476-joir-371890 May 1, 2002 16:4 Style file version Feb 08, 2000 Journal of Insect Behavior, Vol. 15, No. 2, March 2002 (C 2002) Breeding Strategies in Females of the Parasitoid Wasp Spalangia endius: Effects of Mating Status and Size B. H. King1 Accepted October 29, 2001; revised November 28, 2001 Does the mating status or body size of a female parasitoid wasp affect her host size choice or propensity to burrow? In Spalangia endius, using smaller hosts appears to reduce a female’s cost of parasitization but not her son’s fit- ness. However, virgin females, which produce only sons, did not preferentially parasitize smaller hosts. Mated females also showed no host size preference. Mated females burrowed more than virgins in the presence of hosts, although not in their absence. Burrowing may reduce a mated female’s harassment from males, and not burrowing may increase a virgin female’s chance of mating because males avoid burrowing. Mating did not increase female longevity. Greater female size increased the offspring production of mated females bur- rowing for hosts but not in the absence of burrowing and not in virgin females. A female’s size had no significant effect on whether her first drill attempt was on a large or a small host or on the duration of her successful drills. KEY WORDS: breeding strategies; arrhenotoky; virgin; host size; body size; parasitoid. INTRODUCTION The evolution of behaviors is often described in terms of costs and benefits. Individuals are expected to behave in ways which maximize net benefits. -

Parasitoid Case History: an Evaluation of Methods Used to Assess Host Ranges of Fire Ant Decapitating Flies
Porter and Gilbert _____________________________________________________________________________ PARASITOID CASE HISTORY: AN EVALUATION OF METHODS USED TO ASSESS HOST RANGES OF FIRE ANT DECAPITATING FLIES Sanford D. PORTER1 and Lawrence E. GILBERT2 1USDA-ARS, Center for Medical, Agricultural and Veterinary Entomology P.O. Box 14565 Gainesville, Florida 32604 U.S.A. [email protected] 2Brackenridge Field Laboratory and Section of Integrative Biology University of Texas Austin, Texas 78712 U.S.A. [email protected] ABSTRACT The first three papers in this section have discussed factors that affect the efficiency and suc- cess of laboratory host range tests. This paper presents an evaluation of how well those 634 factors applied to our investigations of host ranges of fire ant decapitating flies in the genus Pseudacteon (Diptera: Phoridae). We initially discuss the nature of the fire ant problem (Hy- menoptera: Formicidae: Solenopsis spp.) and the need for effective self-sustaining biological control agents. We briefly review the biology of Pseudacteon decapitating flies, the overall results of our host range tests, and the current status of field releases of these biological con- trol agents. We conclude by discussing how well the recommendations of the three initial papers about 1) statistical procedures, 2) biotypes and cryptic species, and 3) experimental design, plus a recent book on the subject of host range testing, apply to our experiences with fire ant decapitating flies. BACKGROUND OF PARASITOID SYSTEM THE FIRE ANT PROBLEM AND NEED FOR SELF-SUSTAINING BIOLOGICAL CONTROL The major problem with invasive fire ants (Hymenoptera: Formicidae: Solenopsis spp.) is that there are so many of them. -

A Koinobiont Parasitoid Mediates Competition and Generates Additive Mortality in Healthy Host Populations
OIKOS 110: 620Á/628, 2005 A koinobiont parasitoid mediates competition and generates additive mortality in healthy host populations Tom C. Cameron, Helen J. Wearing, Pejman Rohani and Steven M. Sait Cameron, T. C., Wearing, H. J., Rohani, P. and Sait, S. M. 2005. A koinobiont parasitoid mediates competition and generates additive mortality in healthy host populations. Á/ Oikos 110: 620Á/628. Insects are subject to attack from a range of natural enemies. Many natural enemies, such as parasitoids, do not immediately, or ever, kill their victims but they are nevertheless important in structuring biological communities. The lag that often occurs between attack and host death results in mixed populations of healthy and parasitised hosts. However, little is understood about how the effects of parasitism during this lag period affect the competitive ability of parasitised hosts and how this, in turn, affects the survival and dynamics of the surviving healthy host populations. Here we investigate the impact of the timing of introduction, and the strength of that introduction, of a parasitoid natural enemy Venturia canescens (Gravenhorst) on the outcome of intraspecific competition between larvae of the Indian meal moth, Plodia interpunctella (Hu¨bner). In contrast to healthy hosts alone, we find reduced survival of healthy larvae with increasing periods of exposure to greater numbers of parasitised conspecifics. This represents indirect mortality of the host, which is in addition to that imposed by parasitism itself. Furthermore, longer periods of exposure to parasitised larvae resulted in an increase in development time of healthy individuals and they were larger when they emerged as adults. -

The Use of the Biodiverse Parasitoid Hymenoptera (Insecta) to Assess Arthropod Diversity Associated with Topsoil Stockpiled
RECORDS OF THE WESTERN AUSTRALIAN MUSEUM 83 355–374 (2013) SUPPLEMENT The use of the biodiverse parasitoid Hymenoptera (Insecta) to assess arthropod diversity associated with topsoil stockpiled for future rehabilitation purposes on Barrow Island, Western Australia Nicholas B. Stevens, Syngeon M. Rodman, Tamara C. O’Keeffe and David A. Jasper. Outback Ecology (subsidiary of MWH Global), 41 Bishop St, Jolimont, Western Australia 6014, Australia. Email: [email protected] ABSTRACT – This paper examines the species richness and abundance of the Hymenoptera parasitoid assemblage and assesses their potential to provide an indication of the arthropod diversity present in topsoil stockpiles as part of the Topsoil Management Program for Chevron Australia Pty Ltd Barrow Island Gorgon Project. Fifty six emergence trap samples were collected over a two year period (2011 and 2012) from six topsoil stockpiles and neighbouring undisturbed reference sites. An additional reference site that was close to the original source of the topsoil on Barrow Island was also sampled. A total of 14,538 arthropod specimens, representing 22 orders, were collected. A rich and diverse hymenopteran parasitoid assemblage was collected with 579 individuals, representing 155 species from 22 families. The abundance and species richness of parasitoid wasps had a strong positive linear relationship with the abundance of potential host arthropod orders which were found to be higher in stockpile sites compared to their respective neighbouring reference site. The species richness and abundance of new parasitoid wasp species yielded from the relatively small sample area indicates that there are many species on Barrow Island that still remain to be discovered. This study has provided an initial assessment of whether the hymenoptera parasitoid assemblage can give an indication of arthropod diversity. -

The Phylogeny and Evolutionary Biology of the Pimplinae (Hymenoptera : Ichneumonidae)
THE PHYLOGENY AND EVOLUTIONARY BIOLOGY OF THE PIMPLINAE (HYMENOPTERA : ICHNEUMONIDAE) Paul Eggleton A thesis submitted for the degree of Doctor of Philosophy of the University of London Department of Entomology Department of Pure & Applied B ritish Museum (Natural H istory) Biology, Imperial College London London May 1989 ABSTRACT £ The phylogeny and evolutionary biology of the Pimplinae are investigated using a cladistic compatibility method. Cladistic methodology is reviewed in the introduction, and the advantages of using a compatibility method explained. Unweighted and weighted compatibility techniques are outlined. The presently accepted classification of the Pimplinae is investigated by reference to the diagnostic characters used by earlier workers. The Pimplinae do not form a natural grouping using this character set. An additional 22 new characters are added to the data set for a further analysis. The results show that the Pimplinae (sensu lato) form four separate and unconnected lineages. It is recommended that the lineages each be given subfamily status. Other taxonomic changes at tribal level are suggested. The host and host microhabitat relations of the Pimplinae (sensu s tr ic to ) are placed within the evolutionary framework of the analyses of morphological characters. The importance of a primitive association with hosts in decaying wood is stressed, and the various evolutionary pathways away from this microhabitat discussed. The biology of the Rhyssinae is reviewed, especially with respect to mating behaviour and male reproductive strategies. The Rhyssinae (78 species) are analysed cladistically using 62 characters, but excluding characters thought to be connected with mating behaviour. Morphometric studies show that certain male gastral characters are associated with particular mating systems. -
