DocumentOther documentA preliminary study on ecological features of two natural enemies against two vectors of pine wilt disease for mass rearing in Korea
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Two species of the genus Monochamus (Coleoptera: Cerambycidae), M. alternatus and M. saltuarius are well-known as vectors of the pine wilt disease and they causes economically damages in South Korea. Among various control methods to reduce the density of vectors, a method by biological control agents (natural enemies) is eco-friendly indispensable. Since 2017, we have carried out the studies on the parasitic natural enemies againt for the vector species and found two parasitoids, Spathius verustus Chao, 1977 (Braconidae) and Cyanopterus flavator (Fabricius, 1793) (Bracondiae), would be a useful agents for biological controls. For accumulation of biological data, we conducted a preliminary study on life span and parasitic rate of two parasitic wasps against for two vector species. As results, we found that S. verustus has the longest adult life span of 33.4±19.2 days (avg.) in M. alternatus (T=30°C, H=60%) and C. flavator has the longest adult life span of 25.1±10.6 days (avg.) in M. alternatus (T=25°C, H=60%). The average parasitic rate (62.5%) of S. verustus was highest in M. alternatus (T=30°C, H=60%). In addition, it is confirmed that the offsprings of S. verustus can be made by parthenogenetic reproducton. Keywords: Research ID: 3622037 -
DocumentOther documentExploration of new natural enemies of the asian longhorned beetle (Coleoptera: Cerambycidae) in China using sentinel host eggs and larvae
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Asian longhorned beetle (ALB), Anoplophora glabripennis (Motschulsky) is a polyphagous wood boring pest that attacks many economically important orchard, roadside, ornamental and forest trees (>100 species). Due to the widespread planting of poplars and willows, it has become one of the most serious forest pests in China and the Korean Peninsula. This cerambycid has also invaded North America and Europe. In order to control ALB in China, many techniques have been employed such as forest management, traps, insecticides, and biological control. Prior to this study, two native polyphagous parasitoids, Sclerodermus guani and Dastarcus helophoroides are currently being used throughout China to control ALB, and few other parasitoids have been reported parasitizing ALB. In order to find specialist parasitoids of ALB, the Chinese Academy of Forestry and USDA-APHIS have carried out a biocontrol program in China since 2015 by applying the technique of deploying ALB-infested sentinel logs to attract parasitoids in three different sites of China (Beijing, Shanghai, and Jilin). From 2015 to 2020, our survey detected 12 species of hymenopteran parasitoids attacking sentinel Asian longhorned beetle larvae or eggs, namely, Bracon planitibiae Yang, Cao et Gould, Iphiaulax impostor (Scopoli), Spathius glabripennis sp.nov. (Unpublished), Zombrus bicolor (Enderlein) (Braconinae), Callocleonymus beijingensis Yang, Oxysychus scolyti Yang, Zolotarewskya robusta glabripennis ssp. nov. (unpublished), Zolotarewskya anoplophora sp.nov. (unpublished) (Pteromalidae), Eurytoma morio Boheman (Eurytomidae), Eupelmus urozonus Dalman (Eupelmidae), Sclerodermus guani Xiao et Wu (Bethylidae) and Xorides sp. (Ichneumonidae). Total parasitism by all these parasitoids was 7–16% in Beijing, 4–11% in Shanghai, and 0–0.2% in Jilin Province, among which, Spathius glabripennis sp.nov and Oxysychus scolyti with rates of parasitism are 1-4% and 2-10% respectively.

Book (stand-alone)High-profileRinderpest and its eradication 2022
Also available in:
No results found.This book tells the story of rinderpest and its eradication. The focus is on the international coordination that came together after the Second World War in the confident belief that, with vaccines available, the eradication of rinderpest was a practical possibility. In both Africa and South Asia, beginning in the 1960s, there was an initial dramatic success through the coordinated vaccination of cattle across the continents. Unfortunately, follow-up measures could not prevent the return of epidemic rinderpest, albeit to a lesser extent. Chastened by failure, the international community refocused with renewed energy to achieve eradication. The vaccination programmes broadened to reflect a multidisciplinary approach to disease eradication. FAO and the OIE, together with international aid agencies, coordinated policy with the nation states and guided implementation of the era¬dication programmes until success was achieved. -
Book (stand-alone)General interest book24-hour Global Marathon for Sustainability – Food for Earth (2021) 2022
Also available in:
No results found.The FAO elearning Academy together with Future Food Institute, organized the second edition of the 24-hour Global Digital Marathon for Sustainability entitled: “Food for Earth”, in 2021. The event was a knowledge sharing collaborative initiative, fully aligned with the United Nations Sustainable Development Goals Agenda 2030 and FAO’s Strategic Framework. The Marathon has proven to be an extremely powerful initiative to raise awareness among entrepreneurs, startups, scientists, journalists, young leaders, policymakers, general public, farmers and indigenous peoples on the importance of environmental, economic and social sustainability.The publication aims at gathering the multilingual work sessions spread out across the globe, all focusing on the regenerative power of food systems. Overall, the 2021 Marathon had a fantastic global impact, bringing together more than 160 expert voices, in 30 main work sessions, in English, French, Italian and Spanish, reaching more than 150 000 views worldwide, and a global coverage from over 100 online journals, TV channels and networks. In addition, ministers and government representatives from more than 30 countries contributed and endorsed the event. As a result, participating countries have proposed and committed to implement more than 100 climate actions. -
