The spotted lanternfly, Lycorma delicatula (White), is an invasive planthopper that was first discovered in North America in Berks County, Pennsylvania in 2014. Currently, L. delicatula has spread to eight additional states and threatens agricultural, ornamental, and timber commodities throughout the United States. The timing of insect life events is very important in the development of pest management tools and strategies. In 2019 and 2020, L. delicatula phenology was successfully documented in Winchester, Virginia using weekly 5-min observational surveys at established monitoring plots. Each year, L. delicatula were active in the environment from May to November with initial detections of first, second, third, fourth, and adults occurring in May, May, June, June, and July, respectively. Cumulative average growing degree days were also calculated for the onset of each L. delicatula life stage using local weather data and a lower developmental threshold of 10°C. First-instar L. delicatula were initially observed at 135 and 111.5, adults at 835 and 887, and egg masses at 1673.5 and 1611.5 in 2019 and 2020, respectively. Combined, these data can be used by growers and land managers to facilitate timing of effective pest management strategies.

African fig fly, Zaprionus indianus Gupta (Diptera: Drosophilidae), is originally from the Afrotropics but has been expanding its geographical range globally, including the United States. It was first reported in Virginia northward in 2012. The current established range of African species is thought to be limited to the southern states in winter, and populations must disperse northward each season. Adults are normally caught in Virginia in mid-summer and later. African fig fly is a competitive invader and affects the dynamics of native drosophilid communities when it invades a new area. While lacking the hardened, serrated ovipositor seen in spotted-wing drosophila, another invasive frugivore, it may come to outnumber that species in commercial plantings. It can lay eggs and develop in many kinds of fruit that have been otherwise injured. However, the ovipositing fly may take advantage of oviposition sites of spotted-wing drosophila, thereby allowing entry of African fig fly larvae, which may outcompete the original inhabitants. Furthermore, African fig fly may be able to infest certain soft-fruit hosts. Biological control in North America and Europe is limited at this time by immunological responses of host larvae; naturally occurring parasitoids have been unable to achieve significant parasitization.

Brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), is a highly polyphagous invasive insect pest from eastern Asia that feeds on numerous fruit, vegetable, and field crops. Four commercial vineyards in Virginia were sampled in 2012 and 2013 to study the basic biology, seasonality, and distribution pattern of H. halys in vineyards. At each vineyard, two blocks were selected. Weekly 3-min timed count visual samplings were performed in border and interior sections from late May until mid-September. Overwintering adult bugs were first detected in vineyards in May; however, the timing of first detection differed among vineyards. Egg masses were found primarily in June and July, and were usually found on the lower surface of grape leaves, although they were occasionally on the upper leaf surface, on the berry, or on the rachis. All developmental stages of H. halys were found in vineyards, suggesting that grape can serve as a reproductive host for H. halys. Substantial variation in H. halys densities was found among vineyards and throughout the growing season. The first instars were found on egg masses and after molting, dispersed throughout the grape vines. The date on which the first egg mass was collected was considered as a biofix. Based on a degree–day model, there were sufficient degree–days for completion of a generation in Virginia vineyards. Significantly higher numbers of H. halys were collected in border sections compared with interior sections. These results are discussed in relation to the potential pest status of H. halys in vineyards and implications for possible control strategies.
