FlyH2 Aerospace has formed a joint venture with X- Sterile Insect Technique (XSIT) and River Bioscience, which are owned by the Citrus Growers Association of South Africa. Our Joint Venture has been formalised as Greenfly Aviation, and FlyH2 brings the unique capabilities and knowledge required to move the SIT delivery mission, presently being undertaken with manned ground and aerial-delivery methods, onto unmanned platforms. FlyH2 will also undertake delivery of pheromones and other remote sensing solutions required by the industy. Greenfly Aviation is in the process of applying for an operators certificate from the South African Civil Aviation Authority and is planning on beginning small-scale operations from September 2019 onwards.

Greenfly’s Sterile Insect Release Platform with underwing FCM hoppers

Sterile Insect Technique (SIT) Operations

FlyH2 partner, XSIT, breeds sterile False Codling Moth (FCM), and distributes them over citrus and other fruit orchards across South Africa, in this way successfully combating the pernicious wild FCM pest populations. Distribution has been primarily performed by manned aircraft such as gyrocopters, helicopters and crop-spraying aeroplanes.

Unfortunately, the low-flying nature of SIT release poses great risks to pilots, and ground-based operations cannot meet business case owing to overwhelmingly complex logistics For this reason, XSIT decided to look to the future and make use of flying robots to perform the releases. XSIT selected FlyH2 Aerospace as a strategic partner for this new drive, and the partners have formed a joint venture called Greenfly Aviation to cover XSIT’s entire 1,5 million hectare annual service footprint..

This project won FlyH2 Aerospace an award for innovation in the field, as well as a government grant to further develop our flying platforms.

The company is expected to be operating in September 2019. Until then, please visit our partner company, XSIT to enquire about manned aircraft releases.

Sterile Insect Technique (SIT) Systems

Eagle-Owl Sterile Insect Release Platform

Greenfly has created a unique system capable of storing, releasing and accurately counting sterile insect releases. Sterile insect technique (or SIT), is an advanced technology which involves breeding up large numbers of a pest insect species, sterilising them, and releasing them in large numbers to overwhelm and crash the native pest insect population.

Our patent pending underwing hoppers have been designed to release a variety of live insects including pests such as FCM and fruitfly, as well as beneficial insects (predators) into high value export crops such as citrus, grapes, and stoned fruit. The hoppers contain internal electronics that allow for careful and controlled releases as well as accurate counting, to less than 5% error. As the counting is autonomously time and GPS tagged by the hoppers, the data can be exported to a GIS system such as ArcGIS for visualisation and analysis.

Greenfly is preparing to market these systems to international SIT partners.

Pheromone Release

FlyH2 Aerospace is developing a new and advanced platform for release of pheromones which are used to disrupt the mating of pest insects in agriculture. Our international partners are employing world leading technology to target pest species, and our systems will be harnessed to deploy the pheromone products, globally. Pheromone disruption is highly effective, low impact, and an otherwise harmless way of reducing target pest species

Yield Forecasting and Precision Agriculture

As a value added service to its customers, FlyH2 Aerospace is preparing a suite of solutions for Greenfly Aviation. These services, predominantly targeted at citrus include

Yield Forecasting [Citrus]In-Orchard Weeds [Citrus]

FCM Trapping and Data

Greenfly Aviation has long term historical data of both sterile and wild FCM, trapping and infestation data as well as release data. The data dates back 10 years. FlyH2 Aerospace has processed the data into historical geo-referenced visualisations. Both the processed data and visualisations are available as a service.
