Asian citrus psyllid parasitoid releases have hit a total to celebrate in California. At first, rearing enough psyllid parasitic wasps called tamarixia seemed daunting in California. Getting populations established to reproduce was a challenge in 2011, but California Department of Food and Agriculture’s Victoria Hornbaker said the efforts have now hit an incredible milestone.
Hornbaker said the next step is to get parasitism rates and see how effective the wasps are.
