Invasion and Management of Agricultural Alien Insects in China

Annual Review of Entomology, Journal Year: 2015, Volume and Issue: 61(1), P. 77 - 98

Published: Nov. 3, 2015

China is the world's fourth-largest country in terms of landmass. Its highly diverse biogeography presents opportunities for many invasive alien insects. However, physical and climate barriers sometimes prevent locally occurring species from spreading. has 560 confirmed species; 125 are insect pests, 92 these damage agricultural ecosystem. The estimated annual economic loss due to more than $18.9 billion. most harmful insects exhibit some common characteristics, such as high reproduction, competitive dominance, tolerance, benefit mutualist facilitation interactions. Regional cropping system structure adjustments have resulted mono-agricultural ecosystems cotton other staple crops, providing monophagous pests. Furthermore, human dietary shifts fruits vegetables smallholder-based farming systems result ecosystems, which provide resource polyphagous Multiple widespread use greenhouses continuous food winter habitats greatly extending their geographic range. current management consists early-warning, monitoring, eradication, spread blocking technologies. This review provides valuable new synthetic information on integrated practices based mainly biological control a number species. We encourage farmers extension workers be involved training further research novel protection methods that takes into consideration end users' needs.

Effect of Climate Change on Introduced and Native Agricultural Invasive Insect Pests in Europe

Insects, Journal Year: 2021, Volume and Issue: 12(11), P. 985 - 985

Published: Oct. 31, 2021

Climate change and invasive species are major environmental issues facing the world today. They represent threats for various types of ecosystems worldwide, mainly managed such as agriculture. This study aims to examine link between climate biological invasion insect pest species. Increased international trade systems human mobility have led increasing introduction rates insects while could decrease barriers their establishment distribution. To mitigate economic damage it is important understand biotic abiotic factors affecting process (transport, introduction, establishment, dispersal) in terms change. We highlight process: diet breadth, phenological plasticity, lifecycle strategies. Finally, we present alien management that includes prevention, eradication, assessment form modelling prediction tools.

Developing a non-destructive metabarcoding protocol for detection of pest insects in bulk trap catches

Scientific Reports, Journal Year: 2021, Volume and Issue: 11(1)

Published: April 12, 2021

Abstract Metabarcoding has the potential to revolutionise insect surveillance by providing high-throughput and cost-effective species identification of all specimens within mixed trap catches. Nevertheless, incorporation metabarcoding into diagnostic laboratories will first require development evaluation protocols that adhere specialised regulatory requirements invasive surveillance. In this study, we develop a multi-locus non-destructive protocol allows sensitive detection agricultural pests, subsequent confirmation using traditional techniques. We validate for tomato potato psyllid ( Bactericera cockerelli ) Russian wheat aphid Diuraphis noxia mock communities field survey traps. find can reliably detect target insects community samples, including morphological did not initially detect, but sensitivity appears inversely related size is impacted primer biases, loci, sample indexing strategy. While our approach allowed independent validation detection, lack reference sequences 18S 12S restricted its usefulness estimating diversity in samples. The DNA extraction proved invaluable resolving inconsistencies between results, post-extraction were suitable both re-examination re-extraction confirmatory barcoding.

Forest Insect Biosecurity: Processes, Patterns, Predictions, Pitfalls

Annual Review of Entomology, Journal Year: 2022, Volume and Issue: 68(1), P. 211 - 229

Published: Oct. 6, 2022

The economic and environmental threats posed by non-native forest insects are ever increasing with the continuing globalization of trade travel; thus, need for mitigation through effective biosecurity is greater than ever. However, despite decades research implementation preborder, border, postborder preventative measures, insect invasions continue to occur, no evidence saturation, even predicted accelerate. In this article, we review measures used mitigate arrival, establishment, spread, impacts possible impediments successful these measures. Biosecurity successes likely under-recognized because they difficult detect quantify, whereas failures more evident in continued establishment additional species. There limitations existing systems at global country scales (for example, inspecting all imports impossible, phytosanitary perfect, knownunknowns cannot be regulated against, noncompliance an ongoing problem). should a shared responsibility across countries, governments, stakeholders, individuals.

Citizen science can enhance strategies to detect and manage invasive forest pests and pathogens

Frontiers in Ecology and Evolution, Journal Year: 2023, Volume and Issue: 11

Published: Feb. 16, 2023

Incorporating a citizen science approach into biological invasion management strategies can enhance biosecurity. Many projects exist to strengthen the of forest pest and pathogen invasions within both pre- post-border scenarios. Besides value initiatives for early detection monitoring, they also contribute widely raising awareness, informing decisions about eradication containment efforts minimize spread, even finding resistant plant material restoration landscapes degraded by disease. Overall, many actively engage citizens in different stages invasions, but it is unclear how work together across all entire process Here we provide examples each stage process, discuss options developing program biosecurity, suggest approaches integrating biosecurity measures help safeguard resources future.

Fruit Flies: Challenges and Opportunities to Stem the Tide of Global Invasions

Annual Review of Entomology, Journal Year: 2023, Volume and Issue: 69(1), P. 355 - 373

Published: Sept. 27, 2023

Global trade in fresh fruit and vegetables, intensification of human mobility, climate change facilitate fly (Diptera: Tephritidae) invasions. Life-history traits, environmental stress response, dispersal stress, novel genetic admixtures contribute to their establishment spread. Tephritids are among the most frequently intercepted taxa at ports entry. In some countries, supported by rules-based framework, a remarkable amount biosecurity effort is being arrayed against range expansion tephritids. Despite this effort, flies continue arrive new jurisdictions, sometimes triggering expensive eradication responses. Surprisingly, scant attention has been paid recent discourse about multilateral agreements. Much available literature on managing tephritid invasions focused limited number charismatic (historically high-profile) species, generality many patterns remains speculative.
