Rhageletis cerasi (L.) is the most important pest in cherry orchards and it’s attak can affect the quality of fruit on a large percentage (45-100%). The European cherry fruit fly is prezent in all cherry and sweet cherry orchards, therefore monitoring this population is required as an element of integrated protection. The aim of this study is to establish population dynamics in Cluj area. Adult flight was monitored twice a week on yellow sticky panels. Traps were placed in different parts of the orchard. The first captures were recorded in May 29, with a number of 4 adults/orchard and in 24 June we recorded the maximum number, 89 adults/orchard. By monitoring population dynamics we can determine the correct time for application of chemical treatments.

Rhagoletis Cerasi

The European cherry fruit fly, Rhagoletis cerasi (L.) (Diptera: Tephritidae), is one of the most destructive pest in cherry and sweet cherry orchards. Because of the low tolerance for damaged fruit on the market and the restrictions from E.U regarding insecticides, new envioramental safe methods begin to be developed. This paper  prezents preliminary research in monitoring and control of Rhagoletis cerasi L.  with  5 diffent formulations of specific pheromon  (pheromon prodeced by ICC  Raluca Ripan  Cluj-Napoca)  4 of them, have not been  tested yet. Adult flight was monitored twice a week on 22 yellow colored traps,  17 with  certified pheromone and  27 with the 4  new synthesized  formulations. Traps were placed in two orchards: one in which chemical treatments have been  performed and another plantation where no chemical treatments were applied. In the orchard where they applied chemical treatments, the average catch on colored traps was 28.31 adults/trap and in baited pheromone traps the average fluctuated between 11 adults/ trap in V3 and 28,6 adults per trap in V2. In the untreated orchard, the average number of catches on colored panels was 23.33 and in the variants with pheromone baits, this parameter was between 8.5 adults/trap in V5 and 44 adults/trap in V2.Rhagoletis cerasi level of population differ from a plantation to another and that is not strictly related to applied technology culture. Yellow panels shows good functionality in capturing adults. Between the  pheromone baited traps that are in the first stage of testing, higher number of  captures than yellow panel variants, showed the variant V2.

Olive fruit fly is the most harmful pest of olive fruits and important for oil production. Damage involves yield reduction as a consequence of premature fruit drop, but also a reduced quality of olive oil and olive products. There is little available data regarding the biology of Bactrocera oleae in Montenegro. Knowledge of the pest life cycle and development would improve optimization of insecticide application timing and protection of fruits, and reduce adverse effects on the environment. Investigation was conducted on the Zutica variety in an olive grove located in Bar during a three-year period. Population dynamics of the pre-imaginal stages and level of fruit infestation were monitored from mid-July until the end of October. The results of this three-year investigation showed that the beginning of infestation was always at the end of July. It was also found that, depending on environmental conditions, the level of infestation was low until the end of August. In September and October it multiplied, and reached maximum by the end of October. Regarding infestation structure, eggs and first instar larvae were the dominant developmental stages of the pest until the middle of September. From mid-September until mid-October all developmental stages (eggs, larvae, pupae) were equally present in infested fruits. Pupae, cocoons and abandoned galleries prevailed until the harvest.

Rhagoletis Cerasi

The European cherry fruit fly, Rhagoletis cerasi Loew (Diptera: Tephritidae), is a highly destructive pest in sweet and sour cherry orchards with a distribution area throughout Europe and the temperate regions of Asia. It occurs regularly in all production regions of these fruit species in Serbia, damaging up to 10% of cherries in commercial production, while damage can go up to 100% in orchards and on solitary threes unprotected by control measures. In Serbia, European cherry fruit fly most often attacks and damages fruits of the lateripening cultivars of sweet cherry (Van, Stela, Hedelfinger, Bing, Lambert, Drogan?s Yellow). After a sweet cherry harvest, adults migrate to sour cherry where they continue feeding and ovipositing in half-mature sour cherries (prevailingly the domestic ecotype Oblacinska). During their activity period, larvae damage the fruits, so that they can no longer be consumed either fresh or processed. The high percentage of sour cherries damaged by R. cerasi has become a factor limiting exports because the intensity of infestation of this fruit exceeds permissible limits. Pesticide use for controlling this pest, especially in integrated production, is based on a very poor selection of insecticides which cause problems with residual ecotoxicity. Consequently, alternative measures for controlling European cherry fruit fly have been intensively studied over the past few years. This work surveys up-to-date results of various studies on the European cherry fruit fly as a very important pest in Serbia and other South and Mid-European countries. The work contains detailed descriptions of its biological characteristics, flight phenology, infestation intensity and possibilities of fly control in sweet and sour cherry production areas.

The paper presents the data collected from an ecological plot of sweet cherries with an area of 0.5 ha, where different methods of monitoring and combating the main pests were tested: European cherry fruit fly - Rhagoletis cerasi L. and black cherry aphid - Myzus cerasi F. The study took place during the years 2019-2020. European cherry fruit fly monitoring - Rhagoletis cerasi L. was performed with both atraCERAS optical panels and Decis Trap devices, with both a warning and control role, the results obtained highlighting a similar flight dynamics. The control of the European cherry fruit fly, carried out by direct control with the help of Decis Trap devices, the dose of 100 traps / ha, proved to be effective, the Abbott effectiveness indicator registering values between 83.4 - 90.5% in 2019, respectively 81.6 - 87.8% in 2020, depending on the studied variety. To control the black cherry aphid - Myzus cerasi F., the product Prev-Am was mainly used, based on orange oil, which was used with good results for the first attacks observed.

Pupal Diapause

Abstract The Chinese citrus fruit fly, Bactrocera minax (Enderlein), is an economically important pest of citrus. The fly has an obligatory pupal diapause in soil from November to March. However, techniques for predicting or determining the emergence of the adult have, thus far, not been well documented. In this study, we investigated the effects of different pre-diapause temperatures (8, 12, 16, and 20°C) and pupal body weight (five groups according to pupal weight: G-58, 55.0–61.0 mg; G-68, 65–71 mg; G-78, 75–81 mg; G-88, 85–91 mg; G-95, 92–98 mg) on pupal period (the indicator of diapause intensity). The pupal period of B. minax larvae pupated at 8°C was 193.41 d, which was significantly shorter than that of larvae incubated at higher temperatures, suggesting that there was a lower diapause intensity for larvae pupated at lower pre-diapause temperatures. There were also significant differences in the pupal periods at different pupal body weights. The pupal period of G-58 was significantly shorter than that of the heavier groups (G-88 and G-95), and the pupal period increased with increasing pupal body weight in the five groups. Moreover, the pupal period of B. minax significantly and positively correlated to pupal body weight. These findings demonstrate that the pre-diapause temperature and pupal body weight are suitable indicators for predicting the pupal period of overwintering individuals, and the results of this study will contribute to the development of new and effective strategies for predicting the occurrence and population dynamics of B. minax adult.

Rhagoletis Cerasi

The European cherry fruit fly, Rhagoletis cerasi (Diptera: Tephritidae), is a key pest for the cherry production industry in Europe and west Asia that has recently invaded North America. Insecticide applications are frequently employed to control this devastating pest, often without considering its population trends. We developed a novel decision support system (DSS), and field tested it in commercial sweet cherry orchards in central Greece. The DSS includes two algorithms that predict the timing of adult activity in the wild and support pest management decisions, based on R. cerasi population trends and pesticide properties, respectively. Preparatory monitoring of the testing area during 2014, using adult traps, revealed high population densities of R. cerasi in non-managed sweet cherry orchards and low densities in commercial ones. Implementation of the DSS during 2015 resulted in low R. cerasi adult population densities and zero fruit infestation rates in commercial cherry orchards. Similar population and infestation rates were recorded in conventionally treated plots that received on average two insecticide applications compared to the one-half that the DSS treated plots received. Simultaneously, high population densities and fruit infestation rates were recorded in non-managed cherry orchards. Apparently, the implementation of the simple DSS we developed reduces the cost of R. cerasi management and minimizes the chemical footprint on both the harvested fruit and the environment.

We investigated the presence of Melittobia digitata (Hymenoptera: Eulophidae) and its associations with its natural hosts in Veracruz, Mexico. The parasitoid was confirmed to be present and found to attack prepupae of Trypoxylon and Sceliphron (Hymenoptera: Crabronidae and Sphecidae, respectively) mud daubers as well as pupae of the Mexican fruit fly Anastrepha ludens (Diptera: Tephritidae). Since A. ludens is a very important pest of citrus and mango in Mexico and Central America, we evaluated, in laboratory experiments, the quality of A. ludens as host of M. digitata comparing the development of the parasitoid in another unrelated fly species (Sarcophaga [Neobellieria] bullata) (Diptera: Sarcophagidae) and in mud dauber wasps (Trypoxylon sp. and Sceliphron sp.). The Mexican fruit fly appears to be a good-quality host for M. digitata, and the results are discussed in the context of their possible interest as a natural enemy of A. ludens.

The quality of `Ron's Seedling', `American Bing', and `Lambert' sweet cherry drupes was not affected by irradiation doses up to 300 to 1000 gray. Peduncle discoloration increased in `Ron's Seedling' cherries when irradiated at 600 and 1000 gray. A dose of 75 gray prevented adult eclosion of more than 1300 Queensland fruit fly (Dacus tryoni, Froggatt). Larvae treated at the third instar were the least susceptible to gamma irradiation. The results indicated that gamma irradiation is a feasible quarantine treatment against D. tryoni without impairment to the quality of cherries.
