The tamarixia program plays an important part in the overall biological control effort. Due to expense and public opinion, Morgan noted that they have discontinued insecticide programs in urban areas. That has allowed populations of beneficial insects to build up and contribute to the control of ACP.
“There are also other native insects that exist in California that predate on Asian Citrus Psyllid and because we’re not applying insecticides there, they’re actually able to build up numbers,” said Morgan. “We’re looking at things like lacewings and spiders and hoverflies and ladybugs and they build up numbers and they do their part in trying to control the Asian Citrus Psyllid.”
