Research on Crops

Spotted wing drosophila (Drosophila suzukii) belonging to the family Drosophilidae is a harmful insect pest in Russian Federation. At times, it may be specific to classify using adults and larva or nymph samples. The method of molecular diagnosis for D. suzukii has been developed from another non-quarantine species Drosophila sp. using the mitochondrial DNA cytochrome oxidase I region of 709-bp. DNA samples with LCO1490 and HCO2198 primers amplified by Drosophila spp. collections in laboratory samples from Mexico, Egypt and Turkey were compared to other GenBank Drosophila taxa sequences. Based on DNA sequence polymorphisms, the findings of the polymerase chain reaction (cPCR) have shown that these primers (12. dsuz.F/R) classify the exact region of the gene as well as the specific Drosophila suzukii primer. This DNA collection is appropriate for regular use by diagnostic and research organizations as safety measure in quarantine and further reduce the spread of this pest.
