A colony of 200 Listronotus (Listronotus setosipennis) have been safely transported from South Africa to Pakistan. The stem mining weevil is a biological control agent against parthenium. CABI’s Dr Philip Weyl, with the help of Dr Lorraine Strathie (ARC-PPRI) successfully imported the weevils into the new quarantine facility at CABI’s Central and Western Asia (CWA) offices in Pakistan from South Africa.

The weevils arrived safely into their new home in Pakistan with “virtually no mortality” according to Dr Weyl. The insects have been put onto parthenium plants to start CABI’s own colony for host specificity testing of important plants in Pakistan.

Parthenium weed (Parthenium hysterophorus) is considered one of the worst weeds in the world. It has invaded and is widespread in about 48 countries in Africa, Asia and the South Pacific, and has the potential to spread to new countries in Africa, Asia and parts of Europe. In the countries it has invaded, it has devastating effects on the livelihoods of millions of people causing significant economic, health and environmental loss.
