Can One Insect Save An Industry?

It’s just a tiny brown wasp, smaller than a grain of rice, but experts believe a little bug may be able to save California’s $1.8 billion citrus industry from an insect that has already decimated Florida’s orange groves.

The Tamarixia Radiata is a predator from Pakistan that scientists are hoping will help eradicate the Asian Citrus Psyllid, an invasive insect that spreads a disease that kills citrus trees and causes economic and environmental problems.

    Of course introducing a new non-native species is potentially fraught with peril and must be done judiciously.   Furthermore, when the population of an introduced predator finally come into balance with the population of its prey, there’s a likelihood that genetic diversity and evolutionary changes will allow the predator to diversify its prey options so that it is no longer restricted to preying exclusively on its “intended” victims.  However, it should be kept in mind that citrus and citrus pests are introduced non-natives and releasing these parasitoids may be just reacquainting an original predator with one of its original prey species.

    Also, a (gentle) pronunciation correction, Robin:  adelgid is pronounced with a soft “g” like a “j”:  a-DEL-jid.

    Like I said below the importance of discovery of this Wasp is probably the best thing ever happened to citrus Industry. This morning I was reading the editorial and  other articles about the greening disease which has devastated the Industry globally. The most impact is in Brazil and Fl where most of the citrus is grown.
    There is no cure for HLB. Even if you plant a healthy seedling in a grove to bring it to production is very difficult.  Using large amount of insecticide systemic and foliar will only make a dent in the fight against this disease.
    I believe parasitic wasps have been imported before  to fight other citrus pests example Leaf miner. Ofcource all precautions are to be taken. For every decision there is a negaive side.
