Scale insects – such as the coffee mealybug and cassava mealybug – are some of the least studied group of invertebrates in East Africa. However, a collaborative effort has been made to address the threat they pose to smallholder farmers: despite their cross-cutting status as pests in all plant groups, crops, ornamentals, trees and weeds.

Several organisations* in Kenya including CABI, and in conjunction with the UK’s Natural History Museum, have joined forces to train up to 30 new extension officers whose role will include identifying scale insects and communicating theirs risks and how they can be managed with smallholder farmers.

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.

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.

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.
