Program of Activities ................................................... 179 FOREWORD The effective control of pests such as weeds, insects, and diseases is critical to assuring healthy crops and enhancing agricultural productivity. Various pest control methods have been adopted. One is the use of chemical pesticides, which is still the most common method in many APO member countries because it is cheap and often very effective. The effectiveness of chemical pesticides in protecting crops, however, has masked the negative impacts associated with their use. For farmers, the most serious are the acquisition of pest resistance to the chemicals, secondary pest outbreaks, and health hazards associated with the application of chemicals. For consumers, the main problems are pesticide residues in food and environmental degradation. Because of such concerns, there is a great deal of interest in applying nonpesticide control methods. The success of nonpesticide approaches to controlling crop pests requires concerted efforts by the parties concerned, ranging from increased awareness of the method by farmers, policy shifts on plant protection, to better labeling of agricultural products for traceability and informed consumer choice. To review the present use of nonpesticide methods for controlling crop pests in member countries, discuss issues and problems in promoting their use, and formulate measures to address them, the APO organized the seminar on “Nonpesticide Methods for Controlling Diseases and Insect Pests”. This volume is a compilation of the papers and proceedings of the seminar. I hope that it will serve as a useful reference on the subject in APO member countries and elsewhere. The APO is grateful to the Government of Japan for hosting the seminar, in particular to the Ministry of Agriculture, Forestry and Fisheries for providing financial and technical assistance, and to the Association for International Cooperation of Agriculture and Forestry for implementing the program. Special thanks are due to Dr. Peter A.C. Ooi for editing the present volume. Shigeo Takenaka Secretary-General Tokyo August 2005 SUMMARY OF FINDINGS INTRODUCTION The Seminar on Nonpesticide Methods for Controlling Diseases and Insect Pests which was organized by the Asian Productivity Organization (APO) and hosted by the Government of Japan was held in Tokyo from 10 to 17 April 2002. The Association for International Cooperation of Agriculture and Forestry (AICAF)* with financial and technical cooperation of the Ministry of Agriculture, Forestry and Fisheries (MAFF) implemented the program. Sixteen participants from 12 member countries and five resources speakers from: FAO Regional Office for Asia and the Pacific, Bangkok; Secretariat of the Pacific Community, Fiji; National Agricultural Research Center, Japan; and National Institute for Agro- Environmental Sciences, Japan, participated in the seminar. The objectives of the seminar were to: 1) review the present situation in using nonpesticide methods for controlling crop pests in member countries; and 2) identify issues and problems in promoting the use of such nonpesticide methods and formulate measures for addressing such issues and problems. The seminar consisted of the presentation of resource papers and country papers, workshop sessions and field visits to the Ibaraki prefecture. The topics covered by the resource papers were: 1) Some Nonpesticide Methods for Managing Crop Insect Pests – Present Status, Issues and Strategies; 2) Nonpesticide Methods for Sustainable Crop Disease Management in the Asia-Pacific Region: Present Status, Issues and Strategies; 3) Biological Control of Vegetable Pests with Natural Enemies; 4) Nonpesticide Methods for Managing Crop Weeds in the Asia-Pacific Region – Allelopathic Cover Crops; and 5) Control of Plant Virus Disease by Cross Protection in Japan. While the country papers focused on current status of using nonpesticide methods for controlling crop pests in participating member countries. In the workshop participants identified the major issues and problems in promoting the use of nonpesticide methods for managing crop pests in the APO member countries; and suggested strategies/ solutions and action plans to address such issues. The seminar highlights are presented below: RESOURCE PAPERS Some Nonpesticide Methods for Managing Crop Insect Pests – Present Status, Issues and Strategies (Dr. Peter A. C. Ooi) The use of chemical pesticides has been dominating the plant protection since1950s. This parochial approach has led to neglect in the study of alternative pest management methods and increased pest outbreaks in oil palm, rice, vegetable and even tea. However, with advances made in Integrated Pest Management (IPM) in Asia in the last decade, there is growing interest in nonpesticide methods. Two main types of nonpesticide methods are discussed in this paper, namely; biological control and physical and cultural practices. Case studies demonstrated that promoting indigenous and ecological knowledge encouraged development of nonpesticide methods. The first case study of the diamondback moth demonstrated the need to understand that the insect was an introduced pest. It lacked effective natural control factors. This understanding encouraged the importation of effective biological control agents. Following establishment of parasitoids in the cooler highlands, the impact of the parasitoids can only be realized by crucifer farmers if they stop using chemical insecticides. This realization necessitates a non-formal education approach promoted by the Food and Agriculture Organization (FAO) of the United Nations. This approach is better known as the IPM Farmer Field School (FFS). * It was reconstituted to the Japan Association for International Collaboration of Agriculture and Forestry (JAICAF) in 2004. - 1 - In the second case study, rice farmers discovered that arthropod predators feed on rice insect pests. This knowledge helped farmers conserve these friends of farmers by avoiding use of chemical insecticides in their crop. Even for other types of biological control farmer education helps optimize the impact of these natural enemies. The third case of using nonpesticide methods for managing crop insect pests was reported

  • Molecular Basis of Pheromonogenesis Regulation in Moths
    Chapter 8 Molecular Basis of Pheromonogenesis Regulation in Moths J. Joe Hull and Adrien Fónagy Abstract Sexual communication among the vast majority of moths typically involves the synthesis and release of species-specifc, multicomponent blends of sex pheromones (types of insect semiochemicals) by females. These compounds are then interpreted by conspecifc males as olfactory cues regarding female reproduc- tive readiness and assist in pinpointing the spatial location of emitting females. Studies by multiple groups using different model systems have shown that most sex pheromones are synthesized de novo from acetyl-CoA by functionally specialized cells that comprise the pheromone gland. Although signifcant progress was made in identifying pheromone components and elucidating their biosynthetic pathways, it wasn’t until the advent of modern molecular approaches and the increased avail- ability of genetic resources that a more complete understanding of the molecular basis underlying pheromonogenesis was developed. Pheromonogenesis is regulated by a neuropeptide termed Pheromone Biosynthesis Activating Neuropeptide (PBAN) that acts on a G protein-coupled receptor expressed at the surface of phero- mone gland cells. Activation of the PBAN receptor (PBANR) triggers a signal trans- duction cascade that utilizes an infux of extracellular Ca2+ to drive the concerted action of multiple enzymatic steps (i.e. chain-shortening, desaturation, and fatty acyl reduction) that generate the multicomponent pheromone blends specifc to each species. In this chapter, we provide a brief overview of moth sex pheromones before expanding on the molecular mechanisms regulating pheromonogenesis, and con- clude by highlighting recent developments in the literature that disrupt/exploit this critical pathway.

Pfister Danny Haelewaters STUDIES OF THE LABOULBENIOMYCETES: DIVERSITY, EVOLUTION, AND PATTERNS OF SPECIATION ABSTRACT CHAPTER 1: Laboulbeniales is one of the most morphologically and ecologically distinct orders of Ascomycota. These microscopic fungi are characterized by an ectoparasitic lifestyle on arthropods, determinate growth, lack of asexual state, high species richness and intractability to culture. DNA extraction and PCR amplification have proven difficult for multiple reasons. DNA isolation techniques and commercially available kits are tested enabling efficient and rapid genetic analysis of Laboulbeniales fungi. Success rates for the different techniques on different taxa are presented and discussed in the light of difficulties with micromanipulation, preservation techniques and negative results. CHAPTER 2: The class Laboulbeniomycetes comprises biotrophic parasites associated with arthropods and fungi.

  • Report and Recommendations on Cycad Aulacaspis Scale, Aulacaspis Yasumatsui Takagi (Hemiptera: Diaspididae)
    IUCN/SSC Cycad Specialist Group – Subgroup on Invasive Pests Report and Recommendations on Cycad Aulacaspis Scale, Aulacaspis yasumatsui Takagi (Hemiptera: Diaspididae) 18 September 2005 Subgroup Members (Affiliated Institution & Location) • William Tang, Subgroup Leader (USDA-APHIS-PPQ, Miami, FL, USA) • Dr. John Donaldson, CSG Chair (South African National Biodiversity Institute & Kirstenbosch National Botanical Garden, Cape Town, South Africa) • Jody Haynes (Montgomery Botanical Center, Miami, FL, USA)1 • Dr. Irene Terry (Department of Biology, University of Utah, Salt Lake City, UT, USA) Consultants • Dr. Anne Brooke (Guam National Wildlife Refuge, Dededo, Guam) • Michael Davenport (Fairchild Tropical Botanic Garden, Miami, FL, USA) • Dr. Thomas Marler (College of Natural & Applied Sciences - AES, University of Guam, Mangilao, Guam) • Christine Wiese (Montgomery Botanical Center, Miami, FL, USA) Introduction The IUCN/SSC Cycad Specialist Group – Subgroup on Invasive Pests was formed in June 2005 to address the emerging threat to wild cycad populations from the artificial spread of insect pests and pathogens of cycads. Recently, an aggressive pest on cycads, the cycad aulacaspis scale (CAS)— Aulacaspis yasumatsui Takagi (Hemiptera: Diaspididae)—has spread through human activity and commerce to the point where two species of cycads face imminent extinction in the wild. Given its mission of cycad conservation, we believe the CSG should clearly focus its attention on mitigating the impact of CAS on wild cycad populations and cultivated cycad collections of conservation importance (e.g., Montgomery Botanical Center). The control of CAS in home gardens, commercial nurseries, and city landscapes is outside the scope of this report and is a topic covered in various online resources (see www.montgomerybotanical.org/Pages/CASlinks.htm).

  • Pest and Diseases in Mango (Mangifera Indica L.) J
    PEST AND DISEASES IN MANGO (MANGIFERA INDICA L.) J. González-Fernández, J.I. Hormaza IHSM la Mayora CSIC-UMA, 29750 Algarrobo, Malaga, Spain EXECUTIVE SUMMARY In this work, we review the most important pests and diseases that affect mango production worldwide as well as the main measures implemented to control them. Pests and diseases are the main factors that can impact sustainable mango fruit production in the tropics and subtropics worldwide. Commercial cultivation of mango, characterized by expansion to new areas, changing crop management, replacement of varieties and increased chemical interventions, has altered significantly the pest and disease community structure in this crop in the different mango producing regions. In addition, climate change is inducing the emergence of new pests and, whereas globalization and trade liberalization have created wide opportunities for mango commercialization growth, at the same time, this can result in faster dispersion of pests and diseases among different mango growing areas if proper sanitary measures are not implemented. This review covers different topics related to pests and diseases in mango. First, a thorough description of the main pests and diseases that affect mango is provided. Second, the different approaches used in different mango producing countries for chemical and biological control are described. Third, recommendations for appropriate mango management techiques that include integrated pest and disease management, reduction in the use of chemicals and the implementation of a good monitoring and surveillance system to help control the main pests and diseases, are also discussed. Finally, the current knowledge on agrohomeopathy and Korean Natural Farming is analyzed and recommendations on future lines of research to optimize mango pest and disease control are discussed.

  • COLEOPTERA COCCINELLIDAE) INTRODUCTIONS and ESTABLISHMENTS in HAWAII: 1885 to 2015
    AN ANNOTATED CHECKLIST OF THE COCCINELLID (COLEOPTERA COCCINELLIDAE) INTRODUCTIONS AND ESTABLISHMENTS IN HAWAII: 1885 to 2015 JOHN R. LEEPER PO Box 13086 Las Cruces, NM USA, 88013 [email protected] [1] Abstract. Blackburn & Sharp (1885: 146 & 147) described the first coccinellids found in Hawaii. The first documented introduction and successful establishment was of Rodolia cardinalis from Australia in 1890 (Swezey, 1923b: 300). This paper documents 167 coccinellid species as having been introduced to the Hawaiian Islands with forty-six (46) species considered established based on unpublished Hawaii State Department of Agriculture records and literature published in Hawaii. The paper also provides nomenclatural and taxonomic changes that have occurred in the Hawaiian records through time. INTRODUCTION The Coccinellidae comprise a large family in the Coleoptera with about 490 genera and 4200 species (Sasaji, 1971). The majority of coccinellid species introduced into Hawaii are predacious on insects and/or mites. Exceptions to this are two mycophagous coccinellids, Calvia decimguttata (Linnaeus) and Psyllobora vigintimaculata (Say). Of these, only P. vigintimaculata (Say) appears to be established, see discussion associated with that species’ listing. The members of the phytophagous subfamily Epilachninae are pests themselves and, to date, are not known to be established in Hawaii. None of the Coccinellidae in Hawaii are thought to be either endemic or indigenous. All have been either accidentally or purposely introduced. Three species, Scymnus discendens (= Diomus debilis LeConte), Scymnus ocellatus (=Scymnobius galapagoensis (Waterhouse)) and Scymnus vividus (= Scymnus (Pullus) loewii Mulsant) were described by Sharp (Blackburn & Sharp, 1885: 146 & 147) from specimens collected in the islands. There are, however, no records of introduction for these species prior to Sharp’s descriptions.

  • Moths & Butterflies of Grizzly Peak Preserve
    2018 ANNUAL REPORT MOTHS & BUTTERFLIES OF GRIZZLY PEAK PRESERVE: Inventory Results from 2018 Prepared and Submi�ed by: DANA ROSS (Entomologist/Lepidoptera Specialist) Corvallis, Oregon SUMMARY The Grizzly Peak Preserve was sampled for butterflies and moths during May, June and October, 2018. A grand total of 218 species were documented and included 170 moths and 48 butterflies. These are presented as an annotated checklist in the appendix of this report. Butterflies and day-flying moths were sampled during daylight hours with an insect net. Nocturnal moths were collected using battery-powered backlight traps over single night periods at 10 locations during each monthly visit. While many of the documented butterflies and moths are common and widespread species, others - that include the Western Sulphur (Colias occidentalis primordialis) and the noctuid moth Eupsilia fringata - represent more locally endemic and/or rare taxa. One geometrid moth has yet to be identified and may represent an undescribed (“new”) species. Future sampling during March, April, July, August and September will capture many more Lepidoptera that have not been recorded. Once the site is more thoroughly sampled, the combined Grizzly Peak butterfly-moth fauna should total at least 450-500 species. INTRODUCTION The Order Lepidoptera (butterflies and moths) is an abundant and diverse insect group that performs essential ecological functions within terrestrial environments. As a group, these insects are major herbivores (caterpillars) and pollinators (adults), and are a critical food source for many species of birds, mammals (including bats) and predacious and parasitoid insects. With hundreds of species of butterflies and moths combined occurring at sites with ample habitat heterogeneity, a Lepidoptera inventory can provide a valuable baseline for biodiversity studies.

An Abstract of Influence of Soil-Quality on Coffee-Plant Quality and a Complex Tropical Insect Food Web by David J. Gonthier Submitted to the Graduate Faculty as partial fulfillment of the requirements for the Master of Science in Biology (Ecology track) The University of Toledo May 2010 Tropical systems are complex, species diverse, and are often regulated by top-down forces (higher trophic levels control lower trophic levels). In many ecosystems insects, especially herbivores and their mutualists, may be strongly affected by plant quality and other bottom-up controls (nutrient availability, plant genetic variation, ect.). Yet few have asked how plant quality (nutritional and defensive plant traits) can contribute to the population regulation and the complexity of these systems. In this thesis, I investigate the importance of soil-quality to both the elemental and secondary metabolite content in coffee and ask how changes to plant quality can influence hemipteran herbivores, their ant-mutualists, predators, and insect communities in a tropical coffee agroecosystem.

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).
