Information note and management recommendations: thrips damage to citrus, persimmon, and pomegranate.

Given the damage caused by thrips observed since May on leaves and fruit in various citrus, persimmon and pomegranate crops and the confirmation of the presence of Scirtothrips aurantii Faure in certain areas, the following recommendations have been considered appropriate:

Recommendations for the strategy to control leaf necrosis in persimmons

During the 2019 campaign, control failures were detected in some plots in the Ribera Alta region (Alzira, Benimuslem, Guadassuar, and Massalavés). Systematic surveys carried out in 2020 revealed that the resistance of the fungus Plurivorosphaerella nawae to the QoI group of fungicides (strobilurins) was present in most persimmon-producing areas in the province of Valencia.

Monitoring South African Cotonet in citrus

Delottococcus aberiae has become a key pest in the fields where it is present because it causes severe damage and is difficult to control. In addition to the damage typical of other pseudococcid species, this species causes deformation and/or reduction in fruit size. Delottococcus aberiae deforms fruit from petal fall until the fruit reaches a diameter of 2–3 cm.

Recommendations against fruit fly (Ceratitis capitata) in citrus fruits.

Drosophila suzukii treatment notice for cherry trees

In the various areas where Drosophila suzukii is being monitored, populations of this insect are being detected. Remember that attacks tend to be more intense and frequent at the beginning of the harvest, and treatment will be especially necessary in plots that were attacked in previous years and that left cherries unharvested last year (fly damage or cracking, lack of profitability, etc.).

Notice of treatment of plum moth (Cydia funebrana) in plum trees

The second generation of the plum moth has been seen flying between late May and early June in the Ribera and Val d'Albaida regions, and somewhat later in inland areas. Eggs will hatch this week and next. Treat accordingly.

Olive fly (Bactrocera oleae) treatment notice

The olive fruit fly population is beginning to increase this year, so an initial bait treatment is recommended. Once the first pitted olives appear, the next generation of adults will emerge approximately 25 days later, and a second bait treatment is required to control them.
