We have some research going on in the lab to understand the potential of Trichograma ostrineae (a parasitic wasp) to control the western bean cutworm (a pest of corn and edible dry beans). These are very, very tiny native wasps that like to lay eggs inside of caterpillar eggs. There are other pest insects that they attack as well, such as the European corn borer. I have an intern from UNESP, Brazil that is helping me understand the parasitism efficiency of this parasitoid on corn and edible dry beans. Bellow is a short video I took of the tiny wasps moving about inside of a petri dish containing a corn leaf with western been cutworm eggs on it. The eggs are less than 1mm.
