ALPHATEX, in collaboration with the company HORTIBEL, is currently working to find an answer in the fight against the fruit fly on mango trees, which is currently taking place in Réunion.
Alphatex is specialized in arboriculture and horticulture netting. We propose high quality insect screens to protect crops.
Hortibel is a Reunionese company which supply agricultural producers from this region.
Following various observations, here are our findings :
The presence of the fruit fly has a strong impact on the harvest of fruit suitable for consumption, it divides by 5 the quantity of mangoes that can be sent to the sales network.
Mango producers manage their crops :
Producers can not and, most of all, do not want to use chemical solutions. ALPHATEX and HORTIBEL have decided to study a mechanical method in order to support existing tools. Therefore, we tried to use nettings to protect mango trees.
Under certains conditions, the Biotex 800 insect screen can prevent fruit flies from deteriorating mangoes.
The Biotex netting has great characteristics which can solve mangoes producers’ problems. This net is :
The nets were placed on mango trees, the Heidi variety was chosen because its mangoes are very sensitive to the fruit fly. This variety, opposed to the JOSE variety, doesn’t have dried flower stems from the previous year that present a risk and could tear the net.
Trees height does not exceed 3.5 metres. The netting was put on trees when fruits were still green.
The producer did this trial with three replicates :
The net was put in place the 8 of December 2020 and mangoes were harvested the 10 of January 2021.
This one was a control row, without net.
The net was put in place the 8 of December 2020 and mangoes were harvested around the 10 of January.
As you can see of the pictures of this study, nets are wide and not very stretch between trees :
The producer had to adapt his working method to be able to use Biotex nets in his orchards :
There are still some elements that need optimizations for the use of nets on this type of production.
It should be noted that this net could also be used against longicorn. However, this use still has to be tested.
