Back Forward Contents Arthropod index General index Foreword List of targets WHEN THE CSIR Division of Economic Entomology, now Commonwealth Scientific and Industrial Research Organisation (CSIRO) Entomology, was established in 1928, classical biological control was given as one of its core activities. This was indicative of the emphasis to be placed on biological control in Australia for the foreseeable future and was logical when one considers the potential targets for this approach amongst the many exotic pests of the introduced plants on which Australia still depends almost entirely for its agricultural productivity. Biological control has continued as a mainstay of pest management to the present time, with an impressive number of successes over the years. The first comprehensive review of biological control projects in Australia (which also included those in Papua New Guinea) was that of Wilson (1960). This covered attempts against 53 arthropod pests or groups of pests and 12 weeds. There followed coverage of the world scene by Clausen (1978a), which added brief accounts on Australian projects. Worldwide projects on weeds have been regularly summarised in an abbreviated form by M.H. Julien (Julien and Griffiths 1999) but a comprehensive account of the entire range of arthropod projects in Australia up to the present time, now totalling 98 arthropod pests or groups of pests, has been sorely needed for some time. The authors are to be congratulated on their dedication and persistence in amassing the extensive and scattered information required for the task. Congratulations are also due to the Australian Centre for International Agricultural Research (ACIAR), the publisher of this book. This project further extends our close collaboration on biological control activities in the oceanic Pacific and Southeast Asia. ACIAR has already published an impressive number of volumes relevant to the development of significant programs (Li Li-ying et al. 1997; Waterhouse 1993a,b, 1994, 1997, 1998; Waterhouse and Norris 1987, 1989; Waterhouse et al. 1999; Klein Koch and Waterhouse 2001; Morris and Waterhouse 2001). One spectacular success has been the effective control of a serious defoliator, the 3 Back Forward Contents CLASSICAL BIOLOGICAL CONTROL OF ARTHROPODS IN AUSTRALIA Arthropod index banana skipper in Papua New Guinea. This has, so far, halted its spread to General index Australia, with an extraordinarily high estimated benefit–cost ratio of 607:1. This is an excellent example of ACIAR’s policy of taking pre- List of targets emptive action to help an overseas country and, at the same time, Australia, by dealing with a threat to Australian agriculture before it reaches our shores. Classical biological control has the capacity to yield extensive and enduring returns in pest management, though success is not always guaranteed. In their brief overview, the authors estimate an overall success rate of about two-thirds for all projects. This in itself represents a remarkable return on the scientific investment made. I warmly commend this volume not only for the wealth of information it contains, but also as an invaluable record of what can and has been achieved by this approach and as an indication of the opportunities that still exist to extend and improve the approach further for Australia’s benefit.

These publications are of immense importance and relevance to the objectives of both CSIRO Entomology and ACIAR as they promote the economic, social and environmental benefits to be had with appropriate management of insects. His texts have drawn together relevant information available from as many sources as possible, enabling students and research workers to locate easily, most or all of the information on pests and weeds of Pacific and Southeast Asian countries. The books are essential for planning future biological control projects in the region. This most recent book by Dr Waterhouse, Classical Biological Control of Arthropods in Australia co-authored with Dr Sands, is the last in the series on regional biological control programs. It covers the history until 1999, of arthropod biological control introductions into Australia, and updates information on biological control projects carried out since the publication by Wilson (1960). Entomologists, including the scientists affiliated with CSIRO Entomology, are deeply indebted to Dr Waterhouse for the contributions he has made in all the books published after his retirement. They will be referred to for years to come, guiding new initiatives and recording part of the history of safely and successfully controlling pests and weeds, by classical biological control in Australia and the neighbouring developing nations. R.J. Clements Director, ACIAR 7 Back Forward Contents Arthropod index General index Abstract List of targets AN ACCOUNT is provided of attempts at biological control of arthropod pests in Australia. Ninety-eight pests or groups of pests have been involved, totalling some 150 species, most of which are exotic. Some 70 were targetted in specific projects. The pests are listed alphabetically under Collembola (1), Hemiptera (56), Thysanoptera (1), Orthoptera (2), Coleoptera (9), Diptera (7), Lepidoptera (13), Hymenoptera (4), Acari (4) and Diplopoda (1). In addition to a summary table of results, a short dossier on each pest species or group provides (a) a precis of the outcomes, together with basic data on biology and pest status, (b) information on native natural enemies and (c) an account of the attempt(s) at biological control and the biology of the most important natural enemies. Without recent evaluations it is often not possible to assess accurately the level of successful control, but a general overview indicates that about 30 of the target pests are very well controlled and a further 20 are no longer important pests, indicating an overall success rate for target pests of about two-thirds. With the exception of the dung-breeding bush fly, native pests have not proved susceptible to classical biological control. 8 Back Forward Contents Arthropod index General index Acknowledgments List of targets MANY COLLEAGUES within CSIRO Entomology, State Departments of Agriculture and universities have provided valuable information and comment, often providing more accurate and up-to-date accounts of the various projects than is available from publications. Although it is not possible to acknowledge all of the many individuals involved, very special thanks are due to Dr M. Carver for much unpublished information on the aphid pests listed. Mr D. Smith of the Queensland Department of Primary Industries (QDPI), Nambour, Queensland provided most valuable information on scales and mealybugs. Mr J. Feehan supplied unpublished information on the distribution and impact of dung beetles and this was supplemented by Drs M. Tyndale-Biscoe, T.J. Ridsdill-Smith and J.N. Mathiessen. Others in CSIRO Entomology include Drs G.H. Baker, J. Daly, P. Greenslade, B.H. Halliday, G.A. Macqueen, W. Milne, R.J. Milner, L.A. Mound, K.R. Norris, J.L. Readshaw, J.P. Spradbery, R.W.

  • 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.

  • San Jose Scale and Its Natural Enemies: Investigating Natural Or Augmented Controls
    California Tree Fruit Agreement Research Report 2002 SAN JOSE SCALE AND ITS NATURAL ENEMIES: INVESTIGATING NATURAL OR AUGMENTED CONTROLS Project Leaders: Kent M. Daane Cooperators: Glenn Y. Yokota, Walter J. Bentley, Karen Sime, and Brian Hogg ABSTRACT San Jose scale (SJS) and its natural enemies were studied from 1999 through 2002. Natural populations were followed in stone fruit and almond blocks, with orchard management practices divided into “conventional” and “sustainable” practices, based on dormant and in-season insecticide use. Results generally show higher fruit damage at harvest-time in sustainably managed fields, although, these results are not consistent among orchards and exceptions to this pattern were found. In conventionally managed blocks, later harvest dates resulted in higher SJS fruit damage, although this did not hold true in sustainably managed orchards. Results from SJS pheromone-baited traps show a predominant seasonal pattern of SJS densities progressively increasing and parasitoid (Encarsia perniciosi) densities progressively decreasing. These data are discussed with respect to SJS fruit damage and parasitoid establishment and efficiency. SJS and parasitoid sampling methodology and distribution were investigated. Comparing SJS pheromone trap data to numbers of crawlers on double-sided sticky tape and SJS infested fruit at harvest show a significant correlation between pheromone trap counts of SJS males and numbers of SJS crawlers. Results suggest that there is a small window in the season (April-May) when sticky tape provides important information on crawler abundance and damage. Results show a negative correlation between the early season abundance of Encarsia (as measured by pheromone traps) and SJS damage at harvest. These results suggest that early-season ratios of parasitoid : SJS can not be used to predict fruit damage or biological control (these data require more analysis).

(Coleoptera: Coccinelidae) - Micraspis allardi (Coleoptera: Coccinelidae) Reference: - VKASM Wanasinghe, NC Kumarasinghe and KMG Chanchala (2012). Natural Enemies of Sugarcane Woolly Aphid (Ceratovacuna lanigera): A survey in Passara, Sri Lanka. Proceeding of the forth symposium on plantation crop research, pp 163-170 (Annex 01). ii. Variations of population density of the three natural predators of SWA According to the data collected to find out the variations of population density of the three natural predators of SWA (Dipha aphidivora, Micromus sp. and unidentified Syrphid fly larva) from January 2012 to December 2014 indicated that, Dipha aphidivora and Micromus sp. were recorded throughout the sampling period. Peak populations of Dipha aphidivora were recorded in months of December and January in each year. Peak populations of Micromus sp. were recorded during the time periods with low number of Dipha aphidivora and the correlation coefficient value between the population levels of Dipha aphidivora and Micromus sp. is 0.0047. Unidentified Syrphid fly larva was recorded an uneven distribution during the study period (Annual Research Progress, 2014) iii. Relationship of the three natural predators of SWA with some weather parameters The results of the Pearson correlation coefficient values of each three predator with rainfall, temperature and relative humidity (Table 1) have indicated that, there were no significant correlations of each predator with the weather parameters (Annual Research Progress, 2014) (Annex 02).
