“…The identity of other aphid species could be confirmed by BLASTN analysis of the obtained COI sequences to sequences from NCBI GenBank (Figure 3) and available literature: P. humuli (accession number: HE614034, King et al., 2015; MF833985, DeWaard et al., 2019; MH820636, Li et al., 2020; GU978813, Lee et al., 2011), M. persicae (OP185221, Marasinghe et al., 2023; AB506740, Komazaki et al., 2010), and Myzus cerasi (DQ499055, Valenzuela et al., 2007).…”

A new aphid species infesting apricots (Prunus armeniaca L.) was identified for the first time in 2016 in Europe. The invasive aphid was assigned to the species Myzus mumecola (Matsumura, 1917). The species is native to India and East Asia, and it was found to be highly invasive and is currently spreading throughout Europe. Records were confirmed for Italy, Hungary, Serbia, and Germany. For a phylogenetic analysis, wingless (apterae) adults were sampled in spring 2022 in Italy, as well as in Austria and Germany in spring 2023. Our study reports the first record of M. mumecola for Austria. In all three countries, the new pest caused heavy infestations overall in organically managed apricot orchards. Aphids were identified morphologically based on external characteristics, and damages were compared to those reported in the literature. COI and 12S barcoding analyses for aphid samples from Italy, Germany, and Austria were performed to attain a molecular characterization of sampled specimens and to confirm the morphological identification. Only a few COI sequences of M. mumecola were present in NCBI GenBank or BOLD Systems, and no sequences were available for 12S. Therefore, the results provide a deeper insight into the phylogeny of this spreading pest insect. The results of the COI barcoding showed no differences between the sampled populations and other M. mumecola populations from Europe and Japan, while reports from China showed significant differences. All 12S sequences showed no variability between populations from Austria, Germany, and Italy. A phylogenetic analysis of COI and 12S sequences with sequences from other aphid species from NCBI GenBank or sampled in Italy revealed a close relationship of this species with the damson‐hope aphid, Phorodon humuli.

“…Deltamethrin led to a LC 50 value of 3.97 mg/L for M. mumecola , corresponding to the values reported for M. persicae, which range from 1.34 to 381 mg/L [ 16 , 24 ]. Etofenprox showed a LC 50 value of 0.70 mg/L, while values reported for M. persicae were much lower and ranged between 0.026 to 0.089 mg/L [ 25 ]. Flupyradifurone showed a LC 50 value of 0.08 mg/L for M. mumecola , while reports of the LC 50 value for M. persicae ranged from 0.008 to 0.64 mg/L [ 23 , 26 ].…”

The invasive apricot aphid (Myzus mumecola Matsumura) is an important pest of apricot trees (Prunus armeniaca L.). In the presented study, laboratory bioassays using treated leaf disks of apricot were conducted to test the efficacy of twelve insecticides according to the maximum field dose. Additionally, dose-response curves were established for selected insecticides, and the effects on colony development were evaluated. Furthermore, a field trial was conducted to investigate the effectiveness of commonly used insecticides in apricot cultivation. The dose-response curves showed LC50 values ranging from 0.08 mg/L for flupyradifurone, 0.15 mg/L for acetamiprid, 0.70 mg/L for etofenprox, 1.89 mg/L for sulfoxaflor, 2.64 mg/L for pirimicarb, 3.97 mg/L for deltamethrin, up to 6.79 mg/L for tau-fluvalinate. These aforementioned insecticides resulted in mortality rates ranging from 95 to 100% at the field dose. Azadirachtin, flonicamid, and pyrethrins showed mortality rates of 27 to 45%. Spirotetramat reduced the colony development and decreased the number of infested shoots by 86%. Spinosad, which is not recommended against aphids, showed minimal impact; reducing the number of exuviae in nymphs in the colony development bioassay. It can be concluded that the majority of the tested insecticides are effective against M. mumecola.
