Flight tunnel and laboratory trapping assays were conducted using a synthetic pheromone blend (i.e., 6-methyl-5-hepten-2-one, nonanal, and decanal) and a blend of fruit volatiles (i.e., ethanol, ethyl butyrate, acetic acid, ethyl acetate, and acetaldehyde). Results showed that the synthetic pheromone blend along with a fruit-derived attractant captured significantly more beetles than the control. The identification of a potential pheromone is an important step in the search to provide effective control and monitoring of the small hive beetle.

A biological control program began in 2004 based on the importation of the larval parasitoid Lathrolestes thomsoni Reshchikov (Hymenoptera: Ichneumonidae), which previously had suppressed an outbreak of amber-marked birch leaf miner in Alberta, Canada. By 2008, this introduced parasitoid and 2 resident species (native or self-introduced) reduced damage to Alaska white birch by > 50%. In 2020, as a follow up, 100 Alaska white birch in forested parks in Anchorage were cored to see if leaf mining had reduced tree growth during the outbreak and whether biocontrol of amber-marked birch leaf miner allowed tree growth to recover. Compared to 12 yr (1984–1995) before the start of the outbreak, radial growth was suppressed by approximately 16% during the outbreak (1996–2007). During the 11 yr after suppression of damage through biocontrol (2008–2018), tree radial growth of Alaska white birch did not recover, but rather declined further. This pattern may be due to the invasion around 2008 of another birch leaf miner, Heterarthrus nemoratus (Fallén) (Hymenoptera: Tenthredinidae). These findings show that outbreaks of birch leaf miners caused an important drop in growth of Alaska white birch, which has implications for forest productivity and carbon sequestration by birch-dominated forest stands in southeast Alaska.

Even so, plugs are attractive over a relatively short interval, and guidelines suggest that trimedlure plugs be replaced every 6 wk. The present study had 2 goals. First, at periodic intervals up to 10 or 12 wk, we evaluated the performance of plugs containing 4 g of trimedlure (i.e., twice the standard amount) to determine whether the increased loading resulted in an increased period of effective attractiveness. Second, we examined the relationship between trap captures and temporal changes in the residual amount and release rate of trimedlure. In 2 of the 3 field trials conducted in Hawaii and Florida, 4 g plugs weathered for as long as 8 wk, but not for 10 or 12 wk, performed as well as fresh liquid trimedlure applied to cotton wicks. In the other trial, plugs weathered for as long as 12 wk were as effective as fresh liquid. Chemical analyses revealed that the plugs were effective until the residual amount of trimedlure decreased below approximately 1.4 g and the release rate dropped below approximately 2.0 mg per h. The potential usefulness of 4 g trimedlure plugs in large-scale detection programs is discussed considering these findings.

Primero, a intervalos periódicos de hasta 10 o 12 semanas, evaluamos el desempeño de los tapones que contenían 4 g de trimedlure (es decir, el doble de la cantidad estándar) para determinar si el aumento de la carga resultó en un mayor período de atractivo efectivo.

However, the successful establishment of this parasitoid and its efficacy in suppressing emerald ash borer vary among the release sites and regions. We hypothesize that forest microhabitats and parasitoid overwintering life stages affect parasitoid overwintering survival, development, and emergence phenology of adults in the spring. To test this, we placed logs containing 3 different larval stages of S. galinae (early instar larva, late instar larva, and cocoon) in ventilated jars in 2 distinct microhabitat sites, i.e., urban forest and mature natural forest. These were deployed in late fall of 2020 and remained in the field through winter. The emergence of adult parasitoids was recorded in spring through summer of 2021. Parasitoids in the warmer urban site emerged more quickly, emerging 12 d earlier than parasitoids in the cooler mature forest site. None of the S. galinae deployed as early instar larvae diapaused in either urban or forest sites. In both habitats, 27.1 to 32.1% of late instar larvae diapaused. Across overwintering larval stages, the median time of S. galinae emergence was about 24 d in the urban microhabitat, significantly shorter than that (36 d) observed in the mature forest microhabitat. Our findings suggest that environmental factors profoundly affect S. galinae phenology, and consequently emerald ash borer biological control.

UU. Sin embargo, el establecimiento exitoso de este parasitoide y su eficacia para suprimir el barrenador esmeralda del fresno varían entre los sitios y regiones de liberación. Nuestra hipótesis es que los microhábitats del bosque y los estadios de vida de hibernación del parasitoide afectan la sobrevivencia, el desarrollo y la fenología de emergencia de los adultos en la primavera. Para probar esto, colocamos troncos que contenían 3 estadios larvales diferentes de S. galinae (larva de estadio temprano, larva de estadio tardío y capullo) en frascos ventilados en dos sitios de microhábitat distintos, un bosque urbano y un bosque natural maduro.

Raupp, Holly Martinson","doi":"10.1653/024.106.0202","DOIUrl":"https://doi.org/10.1653/024.106.0202","url":null,"abstract":"Abstract The spotted lanternfly, Lycorma delicatula (White) (Hemiptera: Fulgoridae), is an invasive, polyphagous herbivore native to China which was first detected in Pennsylvania, USA, in 2014. As of spring 2022, L. delicatula has spread to 14 states in its introduced range in the eastern US, prompting quarantines, increased surveillance, and new research. Despite known preferences for tree of heaven, Ailanthus altissima (Mill.) Swingle (Simaroubaceae), L. delicatula has been reported from over 100 plants for feeding and oviposition. As L. delicatula continues to spread, individuals have the potential to encounter new host plants for feeding and new substrates for oviposition. In this study, we investigated oviposition and host plant use by nymphs among common trees, shrubs, and vines at 3 field sites in eastern Pennsylvania to determine whether use of plants differs among plant species and with plant size. We then used our field data and information from the literature to assess the risks to 2 nearby, uninvaded habitats in central Maryland. In repeated visual surveys in Pennsylvania, we found L. delicatula egg masses on 10 of 15 plant species, including new observations on Cercis canadensis L. (Fabaceae), Crataegus viridis L. (Rosaceae), and Liquidambar styraciflua L. (Altingiaceae). Egg mass abundance increased strongly with tree size. We found nymphs on 12 plant species, including new observations on C. viridis, and nymphal abundance differed significantly among plant species. Applying results from our field surveys and from the literature to currently uninvaded sites, we found high levels of risk for trees in managed and semi-natural settings; the great majority of trees in these inventories are at risk for use by L. delicatula, though several plant species have yet to be evaluated for risk. Our work highlights the need for continued research into oviposition and feeding choices as well as the urgency for monitoring and preemptive management at sites near known L. delicatula infestations. Resumen La mosca-linterna manchada, Lycorma delicatula (Blanca) (Hemiptera: Fulgoridae), es un herbívoro polífago invasivo originario de China que se detectó por primera vez en Pensilvania, EE. UU. en el 2014. Desde la primavera del 2022, L. delicatula se ha dispersado a 11 estados en su rango invasivo en el este de los EE. UU., lo que provocó cuarentenas, mayor vigilancia y nuevas investigaciones. A pesar de las preferencias conocidas por el árbol del cielo, Ailanthus altissima (Mill.) Swingle (Simaroubaceae), se ha informado que L. delicatula se encuentra en más de 100 plantas para alimentación y oviposición. A medida que L. delicatula continúa propagándose, los individuos tienen el potencial de encontrar nuevas plantas hospederas para alimentarse y nuevos sustratos para la oviposición. En este estudio, investigamos la oviposición y el uso de plantas hospederas por parte de las ninfas entre árboles, arbustos y enredaderas comunes en 3 sitios de campo en e","PeriodicalId":12297,"journal":{"name":"Florida Entomologist","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41665323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
