By adopting integrated pest management (IPM) practices growers are not on their own, Australian entomologist, Dr Paul Horne, told Pukekohe potato growers at a Potatoes New Zealand research update breakfast meeting in late March.

In New Zealand, a team of Lincoln University researchers is impressed with the results from a trial of a mesh cover that is used to protect potato crops from insect pests.

The Environmental Protection Authority (EPA) of New Zealand has approved a type of parasitic wasp as a biological control agent to combat the tomato potato psyllid (a plant louse), which attacks tomatoes, potatoes, capsicums and tamarillos in the country.

Potatoes New Zealand chief executive Champak Mehta says the industry now has the potato psyllid well under control thanks to the knowledge gained through research.

Las mariquitas podrían ser la clave para la salvación de un insecto transmisor de una bacteria para la industria de la papa de Nueva Zelanda.

Research conducted by the Bio-Protection Research Centre at Lincoln University, using the southern ladybird as a biological control agent, has shown the predator to be voracious and effective at reducing tomato-potato psyllid (TPP) numbers.
