An interactive online tool has been developed as a recent outcome from an industry supported project lead by NSW DPI. The citrus gall wasp tool will predict hatching and emergence of the wasp.
The citrus gall wasp tool predicts when adult wasps will emerge from the galls, based on your chosen regional weather station. More importantly, the tool also predicts peak egg hatching. This will enable growers to accurately time systemic chemical control for the wasp. Five seasons’ of monitoring data from the Sunraysia and Riverina were used to develop the tool.
Figure 1 is a screen shot of the ‘Predicted dates’ panel. The tool calculates predicted dates of adult emergence and egg hatching in the current season based on your local weather data. Users of the tool also have the option to view the following:
A trial version of the CGW prediction tool can be found at the shiny apps website.
