In order to effectively control the Ricania shanthungensis, we investigated the light response to adults and developed an adult catching device using light with superior attractiveness. The preference among six light sources such as daylight color, green, etc. for the Ricania shanthungensis adult was most favored with daylight color 97 > Black 79 = Red 79 = Blue 79 > Green 24 > Yellow 13. We have developed an adult catching device using the most preferred daylight colors and behavioral habits of the Ricania shanthungensis.The capture device consisted of two daylight compact lamps (30W, 20W), a yellow plate, and a catcher using water, and caught about 700 individuals a day. The capturing device has a large amount of capturing because adult is activity at high nighttime temperatures, but the capturing amount decreased significantly when the temperature dropped below 23 ℃. More than 85% of the Ricania shanthungensis adults were trapped for 3 hours from 19:00 to 23:00. Therefore, it is considered that the adult capturing device for the control of Ricania shanthungensis is used from middle July to late August when the night temperature is over 23 ℃ and lights up from 19:00 to 23:00.

“…This insect is an economically important pest in its native range [ 5 ], affecting most cultivated blueberry ( Vaccinium spp.) species, including rabbiteye and highbush blueberries, and causing substantial yield loss by injuring flower and leaf buds [ 10 ]. In North America, D. oxycoccana larval feeding can kill up to 80–90% of the flower buds [ 1 , 11 ].…”

“…In Korea, D. oxycoccana was found about a decade ago causing injury to blueberries [ 24 , 25 ]. In recent years, as blueberry cultivation in Korea expanded rapidly from 30 ha in 2005 to 3369 ha in 2020 [ 24 , 26 ], D. oxycoccana became a serious pest of this crop [ 10 , 24 ]. Since its initial invasion, D. oxycoccana has rapidly spread throughout Korea [ 10 , 24 ].…”

Since its initial invasion, D. oxycoccana has rapidly spread throughout Korea [ 10 , 24 ]. Because this pest is not considered a migratory species that can move through long distances for reproduction [ 27 ], D. oxycoccana populations are expected to be isolated and fragmented regionally in cultivated blueberry farms.…”

We compared the population genetic structure between populations of the blueberry gall midge—Dasineura oxycoccana (Johnson) (Diptera: Cecidomyiidae)—from blueberry and cranberry and determined the genetic relationships among geographical subgroups by genotyping 632 individuals from 31 different populations from their native USA regions (New Jersey, Michigan, and Georgia) and from invaded Korean regions using 12 microsatellite loci. Our population genetic analyses showed a clear separation between the two host-associated D. oxycoccana populations from blueberry and cranberry. Using data from only the blueberry-associated D. oxycoccana populations, we identified five genetically isolated subgroups. An analysis of the approximate Bayesian computation suggests that the invasive D. oxycoccana population from Korea appears to have been introduced from an unsampled source population rather than directly from its native range. Our findings will allow for an easier identification of the source of D. oxycoccana into newly invaded regions, as well as to determine their association with blueberry and cranberry, which based on our results can be considered as two distinct species.

Current unmanned aircraft system (a.k.a. drone) technology is an effective tool for aerial survey of pests including weeds, plant diseases, and insects. This study was conducted to develop an aerial survey method that can locate cocoons of the oriental moth, Monema flavescens Walker, for precise and accurate detection of the cocoons in winter to prevent defoliation in the subsequent summer. We used a rotary-wing drone for an aerial survey of M. flavescens cocoons on 15 trees at 3–5 m above the tree canopy. We also conducted a conventional ground survey of M. flavescens cocoons on the same trees for two different conditions of cocoons: open (i.e., adult moths already emerged from cocoons) and closed (i.e., adult moths were not emerged yet). A validation census with destructive sampling was conducted to determine the precision and accuracy of the aerial and ground survey methods. The results of this study showed that from the aerial survey with the drone, images of open cocoons differed from those of closed cocoons. We found higher precision and accuracy and lower type I and II error rates for closed cocoons by the aerial survey with the drone than those by the ground survey. No significant relationships of the number of cocoons with tree height and diameter at breast height were found. This is the first study to demonstrate direct detection of insects with an aerial survey by using a drone.
