This document discusses the risks of invasive alien species spread through global trade. It defines key terms like invasive alien species, quarantine pest, and outlines the risk analysis process. It notes that increased global trade leads to more potential pathways and habitats for invasives. The effectiveness of existing regulatory systems is limited by low inspection rates. Many species in the Global Invasive Species Database have been introduced through trade and transport. Various international agreements and conventions address preventing invasive species spread, including the Convention on Biological Diversity and International Plant Protection Convention. Managing this threat requires strengthened policies and cooperation across many organizations.

2. Definitions
Global trade
 Exchange of capital, goods and services across
international borders or territories.
 Promotes economic growth, efficiency, technology
progress & consumer welfare.
Invasive alien species
 an alien species whose introduction and/or spread
threaten biological diversity
Quarantine pest
 a pest of potential economic importance to the area
endangered thereby and not yet present there, or present
but not widely distributed and being officially controlled
(CBD, 2002)
(FAO, 1997)

3.  Risk analysis: means the complete process composed of
hazard identification, risk assessment, risk management
and risk communication.
 Risk assessment: means the evaluation of the likelihood
and the biological and economic consequences of entry,
establishment and spread of a hazard within the territory of
an importing country.
 Risk management: means the process of identifying,
selecting and implementing measures that can be applied to
reduce the level of risk.
OIE

4. Fate of Global trade
 More trade in goods
More introductions
Higher probability of establishment
 More countries in trade more potential habitats for invasive
 Greater variety of goods & modes of transport greater potential of
invasives and pathways for introduction
 Faster modes of transport increased chances of survival
 System is as strong as its weakest link

5. Effectiveness of Existing System
 Small handful of model countries
 Inspection rate of 1-2% of goods
 Reluctance to place invasives on black lists
 Under-resourced regulatory authorities

14. Global Invasive Species Programme (1997)
 Conserve biodiversity and sustain human livelihoods by minimizing
the spread and impact of IAS.
 Partner organizations- CABI, IUCN, The Nature Conservancy
 In its first phase
 focused IAS assessments
 developed guides and toolkits for policy, regulation, prevention and
management
 adoption by the CBD of a work programme on IAS.
 During a second phase
 implemented activities to engage and inform governments
 stimulate action and cooperation, between governments and different
sectors (e.g. environment and agriculture) to address IAS threats.
 Following the global economic recession- difficulties in securing &
become dormant

 In outer whorls, progressing towards the inner whorls, but emerging
fronds were not infested.

22. Management Strategies
• Application of 1% starch solution on leaflets to flake out the sooty moulds.
• Yellow sticky traps on the palm trunk as well as in iterspaces for trapping
adult whiteflies.
• Encourage build up of parasitoids (Encarsia sp.) and re-introduce parasitized
pupae to emerging zones of whitefly outbreak.
• In severe case, spray neem oil 0.5% and no insecticide is recommended.
