KEY-PESTS OF APRICOT AND CONTROL

The long life of apricot trees allows the formation of entomofauna for a long period of time in the orchards, its keeping in a relative balance and its slow enrichment on a given place.
The main pests (insects, mites and nematodes) which attack apricots are reviewed.
Among the several insects, the peach twig borer (Anarsia lineatella Zell), Oriental fruit moth (Cydia molesta Busck.), some leafrollers (Tortricidae), Gypsy moth (Limantria dispar L.), and some weevils (Curculionidae) are widely the most injurious.
The investigation aims to provide information that will allow pests to be treated at the most susceptible stage of their growth using the minimum number of pesticides.
In recent years a better bio-ecological knowledge of the listed insects should be accumulated.
On this basis their control could be markedly improved by using bio-technical, agronomic and chemical methods.
In general, protective control should be applied early in the season especially when the pests overwinter on fruiting trees.
If the chemical control is applied in pre-bloom or as a first post-bloom spraying it provides good coverage of the trees while leaving minimal pesticide residues on the apricot fruit.
