China Visit

I had a great trip to China - lots of ideas and discussion with my Chinese collaborators.

We spent a few days at the insectary in Guangzhou then ventured up into the mountains about 4 hours drive north where the main crop is rice.

We visited a citrus farm, where releases of Anastatus are being made to target a number of bug pests. We found an Anastatus checking out a group of bug eggs.

Trichogramma japonicus are being mass reared and released for rice stem borer.

Like us, the Chinese scientists have similar issues in assessing biocontrol agents. The rice work will run for several years in order to assess its effectiveness as its not realistic to obtain direct evidence of wasp parasitism in the crop as the rice moth eggs are minute and very difficult to find. So, they can only assess the wasp release program based on damage to the crop. This means observing changes over a number of seasons.

This is a similar approach that we have taken with assessing Anastatus.
