Desiccation tolerance of Termitidae termites in relation to their nest type Environ. Entomol. (IF 1.7) Pub Date : 2023-07-11 Chatchaton Wanthathaen, Chun-I Chiu, Ming-Chih Chiu, Suchart Leelayouthyotin, Patcharin Krutmuang, Hou-Feng Li, Yuwatida Sripontan
The family Termitidae is renowned for its diverse nesting behaviors, with the evolution of epigeal and arboreal nests hypothesized to increase desiccation stress due to greater exposure to air. However, these nests may also alleviate desiccation stress through humidity regulation. To explore the implications of acquiring epigeal and arboreal nests, we investigated desiccation tolerance traits in 16

Nitrogen fixation in the stag beetle, Ceruchus piceus (Coleoptera: Lucanidae): could insects contribute more to ecosystem nitrogen budgets than previously thought? Environ. Entomol. (IF 1.7) Pub Date : 2023-07-07 Isobel E J Mifsud, Palani R Akana, Thomas A Bytnerowicz, Steven R Davis, Duncan N L Menge
Nitrogen (N) is a key nutrient required by all living organisms for growth and development, but is a limiting resource for many organisms. Organisms that feed on material with low N content, such as wood, might be particularly prone to N limitation. In this study, we investigated the degree to which the xylophagous larvae of the stag beetle Ceruchus piceus (Weber) use associations with N-fixing bacteria

Habitat and vertical stratification affect capture of stink bugs (Hemiptera: Pentatomidae) and biological control of the invasive brown marmorated stink bug Environ. Entomol. (IF 1.7) Pub Date : 2023-07-07 Ted E Cottrell, Glynn Tillman, Erin E Grabarczyk, Michael Toews, Ashfaq Sial, Sriyanka Lahiri
Spatiotemporal distribution of stink bugs (Hemiptera: Pentatomidae) and their natural enemies across farmscapes has been studied in more detail recently. However, the impact of plant height on vertical stratification of stink bugs and their natural enemies is rarely addressed across these diverse habitats. In this study, we examined capture of native stink bugs, the invasive brown marmorated stink

Spatial and temporal dispersion of Doryctobracon areolatus (Szépligeti) (Hymenoptera: Braconidae) in orchards infested with Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) Environ. Entomol. (IF 1.7) Pub Date : 2023-06-17 Bruna Piovesan, Rafael da Silva Gonçalves, Sandro Daniel Nörnberg, Jesus Hernando Gomez Llano, Javier Contreras-Miranda, Daniel Bernardi, Dori Edson Nava
Doryctobracon areolatus (Szépligeti) is an endoparasitoid and promising fruit fly control agent. The objective of the study was to determine the spatial (horizontal and vertical) and temporal dispersion of D. areolatus in the field. To evaluate the horizontal and temporal dispersion, two peach orchards were selected. In each orchard, 50 points were marked at different distances from the central point

Blue orchard bee (Hymenoptera: Megachilidae) origin and orchard growing region affect female retention at artificial nest sites in cherry orchards Environ. Entomol. (IF 1.7) Pub Date : 2023-06-17 Morgan B Scalici, Lindsie M McCabe, Diane G Alston, Stephen S Peterson, Matt Yost, Theresa L Pitts-Singer
The blue orchard bee, Osmia lignaria Say (Hymenoptera: Megachilidae), is a solitary, cavity-nesting species used for pollinating spring blooming crops. Commercial stocks are sourced from a few locations in the western United States but are sold across the country. However, the existence of local adaptations of these bees is unknown, such as the propensity to nest in nearby provided materials or to

Releasing and tracking the distribution of adventive Trissolcus japonicus (Hymenoptera: Scelionidae) in Virginia Environ. Entomol. (IF 1.7) Pub Date : 2023-06-10 J Christopher Bergh, Elijah J Talamas, Samuel N Brandt, Ashley Edwards, Lucinda MacRae, Grace Monger, Jason Bowen, Katherine Lawrence, Kathleen Reed, Steve Pottorff
Adventive populations of Trissolcus japonicus (Ashmead), an egg parasitoid of the invasive agricultural pest, brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), have been detected in the United States since 2014. Given its importance as an H. halys biocontrol agent, efforts to redistribute T. japonicus began within some US states. Our surveillance for T. japonicus in northwestern

Pan trapping is an effective method to trap adults of the jujube gall midge, Dasineura jujubifolia (Diptera: Cecidomyiidae) Environ. Entomol. (IF 1.7) Pub Date : 2023-06-08 Hainuo Wang, Long Yang, Yunfei Pan, Jianmin Zhang, Yanhui Lu
Jujube gall midge (Dasineura jujubifolia Jiao & Bu) (Diptera: Cecidomyiidae) is an important pest in jujube (Ziziphus jujuba Mill.) orchards in Aksu, Xinjiang, China. Yellow sticky traps are the main device used for monitoring jujube gall midge adults, but their efficacy is low. Here, we compared the effectiveness of yellow sticky traps with water pan traps (are commonly used for trapping Diptera insects)
