Tridge summary

Research led by CABI and Kenya Plant Health Inspectorate Service (KEPHIS) has identified several African countries as potentially susceptible to invasion by the Apple Snail (Pomacea canaliculata), an invasive pest that was first detected in Kenya in 2020. The pest, which can reduce rice yields by up to 50% and cause significant economic loss, has already infiltrated one of Kenya's largest rice-producing areas. The researchers recommend strict quarantine measures and a multi-faceted management approach, including awareness training, mechanical control, and cultural practices, to contain the spread of the Apple Snail. The research was conducted as part of CABI’s PlantwisePlus programme, supported by multiple international funding sources.

New research led by CABI and including the Kenya Plant Health Inspectorate Service (KEPHIS) reveals that the invasive Apple Snail – which threatens rice crops – could spread further in Africa.A team of researchers from CABI’s regional centre for Africa in Nairobi, working with KEPHIS, suggest that the South West along Tana River, Western Kenya, coastal areas of Kenya, are suitable for invasive Apple Snail invasion as well as other countries including Malawi, Madagascar, Uganda, Mozambique, Tanzania and Ethiopia.However, the risk to Sudan, South Sudan and Somalia is deemed to be “very low.”Invasive Apple Snail (Pomacea canaliculata) was first reported in Kenya in 2020 invading the Mwea irrigation scheme – one of the largest rice-producing areas in the country – where over 80% of the site is now infested.Rice is the third most important crop in Kenya and plays a critical role in increasing household food security and increasing farmers’ incomes. It is mainly produced under ...
