Controlling the papaya mealybug pest – progress made in coastal Kenya
An initiative to combat the destructive papaya mealybug in Kenya is reaping rewards. A natural predator – a parasitic wasp – has been introduced to coastal counties to help control the pest. This tiny wasp is helping to prevent the damage caused by the mealybug. It’s not only helping to save papaya farms. It’s safeguarding…
How has a ‘writeshop’ helped to address invasive apple snail in Kenya?
Invasive species, like apple snail, are a threat to food security. It’s important that they’re quickly managed before they start to spread. One of the best ways to do this is to share plant health knowledge with smallholder farmers. And writeshops are an excellent tool for gathering evidence-based information to do this. In this blog,…
