  • Edible Insects
    1.04cm spine for 208pg on 90g eco paper ISSN 0258-6150 FAO 171 FORESTRY 171 PAPER FAO FORESTRY PAPER 171 Edible insects Edible insects Future prospects for food and feed security Future prospects for food and feed security Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain Edible insects: future prospects for food and feed security and disgust for their consumption. Although the majority of consumed insects are gathered in forest habitats, mass-rearing systems are being developed in many countries. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. It shows the many traditional and potential new uses of insects for direct human consumption and the opportunities for and constraints to farming them for food and feed. It examines the body of research on issues such as insect nutrition and food safety, the use of insects as animal feed, and the processing and preservation of insects and their products. It highlights the need to develop a regulatory framework to govern the use of insects for food security. And it presents case studies and examples from around the world. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock.

    sustainability through science & innovation PestFacts Issue No. 6 - 29th July 2016 So you think you found armyworms?! Sclerotinia stem rot of canola in 2016 More caterpillars Symphilids - white millipede-like invertebrates hold back ryegrass pasture So you think you found armyworms?! Armyworms are about…but so are ‘herringbone caterpillars’ and possibly other species. So how do you tell them apart? Where have they been reported? For the second consecutive year, armyworm (Leucania convecta or Persectania sp.) damage in cereals has been reported in the Victorian Mallee and NSW Riverina near Swan Hill. In the same region Proteuxoa or ‘herringbone caterpillars’ have been chewing lentil, pea and chickpea crops. Also in the Mallee district, these caterpillars have been found in canola near Ouyen. However Proteuxoa activity has not been restricted to broadleaf crops. They have been found alongside larger populations of armyworm in a barley crop northeast of Birchip. In this case the paddock had a heavy stubble load and damage was mainly attributed to armyworm activity. Proteuxoa have also been observed in several wheat crops and a barley crop north of Manangatang. In the NSW lower western region near Lake Mungo, large numbers (>40/m2) have damaged wheat. Near Deniliquin in the NSW Riverina, considerable numbers (12/m2) of Proteuxoa in a barley crop were reported, alongside lower numbers of pasture day moth (Apina calisto). At this stage the damage is not severe enough to warrant control. Distinguishing common caterpillars in crops Armyworm are often confused with Proteuxoa, cutworms and native budworm. Most caterpillars found in crops are known as Noctuids.

If you are unsure of what you are finding use the PestFax Reporter app to send a report to the PestFax team requesting identification. While there are plenty of reports of volunteer regrowth throughout the wheatbelt, the PestFax team had not received any green bridge disease reports when this issue went to print. Significant rainfall experienced by growers in February and March across the Western Australian wheatbelt has resulted in weeds and crop volunteers germinating in paddocks and along roadsides. This vegetation can serve as a ‘green bridge’ for diseases which need a living plant to survive, such as rusts and viruses. These weed and crop volunteers can also act as a between-season host for root diseases and aphids.

  • Insect Outbreaks in Eucalyptus Globulus Plantations
    INSECT OUTBREAKS IN EUCALYPTUS GLOBULUS PLANTATIONS Ian Abbott Department of Conservation and Land Management Research Centre, Como (Prepared June 1990) 1. Executive Summary • All available information about insect problems in globulus plantations in South western Australia is reviewed. • Nine insect species (actual or potential pests) have so far been recorded in globulus. This is, however, an underestimate as few specimens have been collected and the taxonomy of some species requires clarification. • Four species are of most concern: Wingless Grasshopper, African Black Beetle, Leafblister Sawfly, and Spring Beetle. The grasshopper and black beetle are known to cause tree mortality through defoliation and bark chewing respectively. Leafblister Sawfly and Spring Beetle probably only cause growth loss. • Information on the recognition of the feeding stages of each insect species, their life cycle, control and other aspects is summarized. • It is recommended that a Professional entomologist and Technical assistant be appointed to the Entomology Research Program to take charge of research into the management of these pests. • Interim measures, involving minor redeployment of staff with Entomology Research Program, are proposed. Nevertheless these changes are insufficient to cope with the problem. • A review of interstate and overseas experience with plantation entomology is appended. 2 2. Introduction My brief (P. Christensen, pers. comm.) was to summarize what is known about actual and potential insect problems in globulus plantations in Western Australia and to provide expert advice about these problems and how they might be overcome. 3. Injurious insect species recorded Nine species have so far been recorded, based on specimens held in the CALM Forest Insect Collection (CALM FIC) at Como and Manjimup.

    FLY TIMES Supplement 2, September, 2018 Stephen D. Gaimari, editor Plant Pest Diagnostics Branch California Department of Food & Agriculture 3294 Meadowview Road Sacramento, California 95832, USA Tel: (916) 262-1131 FAX: (916) 262-1190 Email: [email protected] Welcome to the second Supplement issue of Fly Times! I am very pleased to have started this series, as it will facilitate distribution of larger works such as this one. Please let me encourage you to consider contributing to both the regular Fly Times, and if you are so inclined, to the Fly Times Supplement series. The Fly Times comes out twice a year – April and October (although usually late it seems!), while the Supplement can come out any time. Both this Supplement, and the first one in 2017, are historical in nature, focused on the life and times of dipterists of the past. Future Supplement issues can be historical like this one, or focused on any other dipterological topic, from original research, to travelogues and collecting adventures, to larger taxon-focused themes. The electronic version of the Fly Times continues to be hosted on the North American Dipterists Society website at http://www.nadsdiptera.org/News/FlyTimes/Flyhome.htm, as is the Fly Times Supplement series. Also note, the Directory of North American Dipterists is constantly being updated. Please check your current entry and send all corrections (or new entries) to Jim O’Hara – see the form for this on the last page. Issue No. 61 of the Fly Times will appear very soon, hopefully around the end of next month.
