We’ve also had some good reports from growers that had been making Anastatus releases up to October 2013 when we had to cut back releases due to our mass rearing issues.

These include Mark Fleming who manages a macadamia farm at Tregeagle NSW. He’s made regular releases of Anastatus and reported a big drop in damage last season but was unable to get wasps from October 2013. Nevertheless he says his damage is still way down on what it used to be and spends a lot less time on sorting.

Similarly, Rick Paine, (see last year LINK) continued to have incredibly low levels of bug damage this year (Pers Comm). Ian Gall has noticed “a definite difference” on his property near Rosebank. Graeme Fleming has been releasing in a conventional block of macs next to Henri Bader (see above) and reports very low levels of bug damage. And his organic block at Knockrow also has lower levels than usual.

I visited Russ Hopper, a mac grower near Bundaberg, a few months ago. The source of his bugs seems to be the house orchard and this year there was very little damage on those trees including the frangipani that usually gets hammered. This carried over into very low damage levels in the crop.

So all this is very encouraging and great to see growers are starting to reap the benefits of their commitment and patience. For some biocontrol agents it may take several seasons to filter through into changes in pest damage. And as we have found the mass rearing has been more challenging than we would have liked. We are sure we can make it more reliable over time.

Thanks again to all those growers and consultants who have supported this work.

Our plans for the next few months

Refine Anastatus the mass rearing and field delivery systems.

Work towards having more Anastatus wasps available next season.

Contact growers in early August to call for orders for the season.

China Visit

Our Chinese collaborators are also going to experiment with holding back some of their moths and sending us “fresh” eggs in August-September. This will be a trial run and if the quality of the eggs is good then we will receive more eggs this way next year.

They have also secured funding to pay for me to visit China in late July. We have many fine points to discuss about mass rearing and field use. Anastatus have been used in China for decades. As well as rearing Anastatus for lychee stink bugs, they are also rearing Trichogramma for a range of crops. So we have a lot to talk about.
