BackgroundFruit flies (Family Tephritidae) is one of the most destructive and economically challenging pest insect of fruits and vegetables
It is responsible for loss of export markets and poor farm gate prices of fruits and vegetables
Fruit flies are are insects (Diptera) and undergoes complete metamorphosis: eggs- larva- pupa- adult
Only larva (maggots) are extremely damaging. Adults in additioncause economic injury through stippling (oviposition marks)

Present in Africa: Bactrocera (486 species); Ceratitis (70 species); Dacus 235 (species);Not in Africa: Rhagoletis (62 species); Anastrepha (183 species);
There is high diversity of pest fruit flies

Relevance of the Project
Purpose:
To build capacity of African countries in the management of fruit flies using area wide approach and incorporating sterile insect technique
Fruit flies infest crops at times you cannot use insecticides without harming the consumers. the fruits are usually ripe at time of infestation. Hence pesticides may not be useful
Fruit flies cause immense social and economic losses and are currently managed effectivelyby SIT
SIT (sterile insect technique) is a method that uses sterile insects (males) to flood them in the wild, and by so doing they mate with wild fertile individuals, resulting to no progeny
The largest global fruit fly factory
Currently producing 1.2 billion sterile flies weekly with capacity of 2 billion week!
Project Outputs/Efficiency and effectiveness
Training Counterpart: Post graduate certificate in SIT and area wide IPM, Mauritius, 2016 (first ever PGC course in SIT globally)
Trained 4 Kenyans on SIT and area-wide IPM, Kenya 2017(October)
Trained 1 Kenyan on SIT and area wide IPM, Mexico/Guatemala, November 2017
More training planned
Fruit fly management kit worthy KES 125,000
Held Africa wide training on SIT and AW-IPM in Kenya (this is amajor capacity building for Kenya to hold similar trainings)
Supported Kenyan participation in 4th Area wide IPM conference inVienna, May 2017
Impact analyses (socioeconomic benefits)Fruit flies are leading economic pests not only Kenya but global
Kenya in 2008 lost Avocado market in South Africa as a result of Bactrocera dorsalis presence. Since then, we have not gained access as the pest continues to cause havoc
Kenya cannot export fruits to USA or some european countries due to this pest. Therefore opportunities for incomes and employment creation are lost
* Shelf life of fruits in Kenyan market has reduced drastically, making fruitscheap and not economically sustaining farmers
• Farmers resulting to use of pesticides even when banned, to ensure no damage
• High use of ripening chemicals because fruits are harvested before theyripen to avoid infestation. this has lowered quality of produce, with most fruits not tasty
RAF 5074 has enhanced capacity for Kenya to develop sustainable systemfor fruit fly management
Sustainability in absence of IAEAAlready there exists a National Fruit fly program which isresponsible for fruit fly activities
The knowledge gained and capacity built from this RAF5074 project will help develop sustainable mechanism for the pest control
There are prospects for use of sterile flies to manage fruit flies inKenya. this is a long term goal that can be effected with time
We will continue to engage IAEA on matters of fruit flies.
Way forwardKALRO looking forward to develop mass rearing facility for fruit flies and SIT facility
However, this is a long term strategy
Initially is to develop a program that leads to the use of sterile flies
* Further, other compatible methods will be incorporated while implementing area-wide IPM for the fruit flies
