Our Results

Over the last 13 years, the sterile insect release program significantly reduced the wild population of the FCM, leading to less fruit infestation.

FUTURE EXPANSION AND PROJECTS

Commercial releases are also done on various deciduous varieties such as table grapes, apricots, peaches, nuts and pomegranates, with excellent results.

OUR RESULTS DATA

ELEPHANTS RIVER VALLEY

The area-wide release of sterile T. leucotreta had encouraging effects on combating wild FCM as an increasing amount of sterile male moths were trapped from 2007 up to date. Trap catches of wild male moths declined from 13.0 moths per trap prior to sterile moth releases in 2006 to 0.3 wild moths per trap in 2016. The average pre-SIT fruit damage of 30 oranges per tree was documented during 2006-7 in the region scheduled for SIT introduction the following season. Fruit infestation by T. leucotreta decreased to 0.02 infested fruit per tree in 2016.

SUNDAY RIVER VALLEY

Numbers of wild FCM adults gradually declined.

GAMTOOS RIVER VALLEY

Effectiveness of the program in the Gamtoos River valley is very successful. This is mainly due to the continues support form the producers over the last couple of years. The natural topography of the area is of such that the program can run efficiently.
