NZ potato and tomato growers relieved at the release of pest eating wasp

A pest which has cost the New Zealand potato industry over $120 million since 2006 may be on the way out thanks to a wasp which has been released in Hawke’s Bay and Canterbury. The tamarixia trioaze, a wasp that comes from the United States and Mexico, destroys the tomato potato psyllid pest by laying an egg on the psyllid. The wasp eggs hatch and the larvae feed on the TPP. Eventually, the larvae will chew a hole through the TPP’s shell to emerge as an adult. Vegetable Research and Innovation Board coordinator Sally Anderson said the arrival of the wasp was a relief for greenhouse growers.
