Invasive alien species (IAS) have devastating impacts on native biota, causing the decline or even extinction of native species, negatively affecting ecosystems. Invasive plants, animals, insects and microorganisms enter and establish in environments outside of their natural habitat. They reproduce rapidly, out-compete native species for food, water and space, and are one of the main causes of global biodiversity loss. Species can be introduced deliberately, through for example, fish farming, pet trade, horticulture, bio-control or unintentionally, through such means as land and water transportation, travel, and scientific research.

CABI, under its Action on Invasives programme, is working to manage the already existing and potential invasive species in Pakistan. Pest Management Decision Guides (PMDGs), through the Plantwise Knowledge Bank are practical, step-by-step tools for plant doctors and extension agents to give advice following the principles of integrated pest management (IPM).

CABI publishes recommendations to fight scourge of parthenium weed in Central West Asia

Parthenium in Pakistan

CABI has published a new evidence note highlighting a list of recommendations to fight the highly-invasive parthenium weed which can have significant impacts on human health, the environment, livestock production and health and crop yields.

The report Parthenium: Impacts and coping strategies in Central West Asia, states that the aggressively-spreading weed, now classified as a ‘superior weed,’ is extremely prolific being capable of producing up to 30,000 seeds per plant – a key factor in its global spread to 48 countries including India and Pakistan.

New pest risk analysis decision support tool in development from CABI

Colorado beetle eats a potato leaves young.

A Pest Risk Analysis (PRA) allows National Plant Protection Organisations (NPPOs) to assess risks posed by pests or pathways of quarantine concern, and identify options to manage those risks. Recognising that there was a need for support in the completion of PRAs, CABI, under its Action on Invasives programme, has designed and is developing an online PRA tool.
