From Viet Nam Mews: Stick insects destroy 24ha of forest
HAI PHONG — Stick insects destroyed nearly 24ha of forest in Cat Ba National Park of the northern city of Hai Phong during the past week.
The insects appeared in the park in 2007. They have six long legs and can move quickly, making them difficult to catch. The insects' density in the park is as high as dozens of thousands on each tree.
The Hai Phong Department of Agriculture and Rural Development has sprayed plants to prevent the insects from spreading.
I've been working on a paper surveying this sudden population explosions of stick insects, but have found it quite hard to find contact details for anybody in Vietnam who might be able to provide more info - any ideas gratefully received, either leave a comment or e-mail me.
