Bactrocera dorsalis, previously known as Dacus dorsalis and commonly referred to as the oriental fruit fly, 

is a species of tephritid fruit fly that is endemic to Uganda and East African as well. Originated from southern Asia.

 It is one of the major pest species in the genus Bactrocera with a broad host range of cultivated and wild fruits.

 Male B. dorsalis respond strongly to methyl eugenol, 

In the orchards of East Africa, Uganda) a silent adversary lurks. 

   The mango fruit fly, Bactrocera dorsalis

 threatens not just the beloved mango but over 40 different fruit types. 

But fear not, for knowledge is power, and armed with the right strategies, farmers can turn the tide against this pervasive pest.

In East Africa, damage from fruit flies has been reported to range between 40 - 80 % since the invasion by one of the most destructive mango pests – BACTROCERA DORSALIS. 

This fruit fly species is the dominant pest in lowland areas. The pest is also known to attack over 

40 unrelated fruits which include 

                            MANGOES

                           ORANGES, 

                            TOMATOES, 

bananas, 

                             GUAVA, 

 

                            SOURSOP

                             AVOCADOES 

and many more.

                            TERNGERINE 

Other fruit fly species of economic importance are the Ceratitis Cosyra,

 C. rosa, 

Ceratitis anonae,

 C. and C. fasciverantris -

 these pests also attack other cultivated and wild fruits. 

The female fruit fly lays its eggs under the skin of the mango (fruits) The eggs hatch into whitish maggots that feed on the decaying fruit, which causes rotting and great damage to the fruits, resulting in great losses to farmers. 

Farmers can control fruit flies through the following 

INTEGRATED PEST MANAGEMENT (IPM) methods:

1 - FOOD BAITS:

 The food bait attracts the fruit flies from a distance to the spot of application where the flies feed on the food bait which contains a “soft” pesticide. They die when they eat the bait, killing them before they infest the fruits. 

We recommend using food baits like 

NuLure®,

 Buminal, 

GF-120®,

 Solbait, 

Biolure®,

 Torula yeast®, and Hymlure®, and Hymlure® mixed with biopesticides such as spinosad.

 These attract and eliminate fruit flies effectively. For instance, GF120® is pre-mixed with spinosad for convenience

The bait is applied to a localized 1 m² spot on the fruit tree canopy using CP 15 knapsack sprayer when the mango fruits are about golf ball size (about 4cm in diameter). 

This application should be continued until fruit harvesting is completed.

                     FRUITFLY TRAP, 

with bait inside the trap Commercial baits in the market include NuLure®, Buminal, GF-120®, Solbait, Biolure®, Torula yeast®, Hymlure® - these can be mixed with biopesticides such as spinosad and applied as explained above. GF120® is already mixed with spinosad. 

Traps baited with such food baits capture both females and males of several species of fruit flies.

 Apart from Biolure, which is replaced every four weeks, all the other food attractants are renewed every 7 days. +256756617920 for fruit fry traps.

However, because these baits are expensive and not readily available,  

The INTERNATIONAL CENTRE OF INSECT PHYSIOLOGY AND ECOLOGY ( ICIPE )

 is in collaboration with a private partner in Kenya to fast-track the production of local bait (Dudulure®) as an alternative source that is equally effective and can replace the more expensive products in the markets. 

This food bait will be made easily accessible to all farmers at much lower and reasonable prices for the local farmers. 

                    SOIL INOCULATION: 

Our agronomy services include soil inoculation using a potent fungal isolate, 

(METARHIZIUM ANISOPLIAE) 

that is effective against ADULT , PUPA & LARVAL stages of major fruit fly species that are of Native and of Exotic origin. 

During the developmental cycle of fruit fly, the mature larvae leave the fruit and drop to the ground where they burrow into the soil and form a resting stage called puparia. 

An important part of fruit fly suppression includes soil treatment with these fungal pathogens to kill the maggots and puparia in the soil. 

The fungus is formulated into granules, which can be dispersed by hand and then raked into the soil while oil-based formulation is applied using a knapsack sprayer. 

Both formulations are effective and only one application is required on the ground below the mango canopy. 

Application is usually done at the onset of fruiting and can persist in the soil for over a year. 

                 ORCHARD SANITATION: 

Orchard sanitation involves the collection and destruction of all fruit fly infested mangoes found on the trees and fallen ones on the ground to significantly reduce fruit fly populations in the orchard. 

This should be done at least twice a week for the entire mango fruiting season. 

In this regard, the collected fruits should be destroyed or composted by dumping them in an Augmentorium rather than burning or burying deep in the soil or putting them into plastic bags to kill the fruit fly maggots. 

                    THE AUGMENTORIUM

is a tent-like screen structure that is designed to retain fruit flies (while allowing their parasitoids to leave or enter the structure).

 Augmentoria can be easily constructed by farmers.

 It serves the double purpose of field sanitation and conservation of natural enemies of fruit flies. The tent is designed in such a way that it is able to confine all the fruit flies that emerge from the fallen rotten fruits that are collected from the field and deposited in the structure, 

while at the same time conserving their natural enemies by allowing the parasitoids to escape from the tent through a fine mesh at the top of the tent. 

BIOLOGICAL CONTROL 

Biological control is the use of beneficial insects like parasitoids whose immature life stages develop within the fruit fly host (pest)

Utilizing natural enemies like parasitoids, such as

 Fopius arisanus and Diachasmimorpha longicaudata,

 is a cornerstone of our natural pest solutions.

 These beneficial insects are released for free in major mango-growing zones and are instrumental in controlling fruit fly populations.

 ultimately killing the fruit fly before they emerge.

 They are also referred to as “farmers’ friends” and help to reduce the damage caused by fruit flies. 

One of the most outstanding successes against fruit flies is attributed to the use of the 

egg parasitoid, Fopius arisanus against Bactrocera dorsalis. 

It attacks the eggs of the fruit fly in the fruits and develops through the larval stages of the fruit fly and emerges as an adult parasitoid in the pupa of the fruit flies. 

This parasitoid is presently being released for free in major mango growing zones in East Africa and Africa at large. 

Another important parasitoid that is being released alongside with F. arisanus in Uganda and other East African countries is a solitary larval-pupal parasitoid called Diachasmimorpha longicaudata. Which is also successful on its own.

MALE ANNIHILATION TECHNIQUE (MAT): 

To further enhance ( MAT ), This involves the use of fruit fly traps particularly 

LYNFIELD TRAPS 

consisting of a male attractant 

(METHYL EUGENOL) 

combined with an insecticide, which are distributed at regular intervals over a wide area in the mango orchard to reduce the male fruit fly populations. 

This helps low levels of mating or does not occur. 

MAT is currently being promoted by ICIPE as a component of the IPM Strategy for fruit flies. Male attractants such as 

methyl eugenol, 

cuelure, 

vertlure and terpinyl acetate 

can be used with appropriate toxins such as Nimbecidine® spinosad and deployed in the orchards. 

The traps should be serviced after every 6 – 8 weeks. 

                        CROP PROTECTION

, we promote MAT using Lynfield traps with male attractants like methyl eugenol combined with an insecticide. This method effectively reduces male fruit fly populations, thereby disrupting mating.

                      FRUIT PROTECTION: 

Fruit protection involves 

wrapping, bagging or sleeving 

of individual fruits or bunches of fruits with plastic or paper bags to prevent adult fruit flies from laying eggs on the fruits. 

The fruits must be wrapped well before fruit fly attack at least one month before harvest. 

The method is effective especially if used to protect fruits meant for export or home use.
