The Stink Bugs (Hemiptera: Heteroptera: Pentatomidae) of Washington State
Froeschner (1988) recorded 23 species of stink bugs (Hemiptera: Heteroptera: Pentatomidae) from Washington State. Based on material primarily housed in the M. T. James Entomological Collection at Washington State University, the number of species is increased to 51. Three species recorded by Froeschner (1988) were not found in our collections: Apateticus crocatus (Uhler), Chlorochroa rossiana Buxton and Thomas, and Tepa rugulosa (Say). Species recorded from Washington State for the first time are: Apoecilus bracteatus (Fitch), Perillus bioculatus (Fabricius), Podisus maculiventris (Say), P. pallens (Stål), P. placidus Uhler, P. serieventris Uhler, Zicrona caerulea (Linnaeus), Halyomorpha halys (Stål), Brochymena quadripustulata (Fabricius), B. sulcata Van Duzee, Acrosternum hilare (Say), Aelia americana Dallas, Banasa euchlora Stål, B. tumidifrons Thomas and Yonke, Chlorochroa congrua Uhler, Coenus delius (Say), Cosmopepla uhleri Montandon, Dendrocoris pini Montandon, Euschistus servus (Say), E. tristigmus (Say), E. variolarius (Palisot), Holcostethus limbolarius (Say), Neottiglossa sulcifrons Stål, N. undata (Say), Prionosoma podopioides (Uhler), Tepa yerma (Rolston), Trichopepla grossa (Van Duzee), and Amaurochrous vanduzeei Barber and Sailer
Yellowjacket Wasps (Hymenoptera: Vespidae) Trapped in Alaska with Heptyl Butyrate, Acetic Acid and Isobutanol
Eight species of vespine wasps were captured in traps near Fairbanks, Delta Junction and Palmer, Alaska, during 2003 and 2004. These were Vespula vulgaris L., V. acadica (Sladen), V. consobrina (Saussure), V. rufa (L.)(=intermedia [Buysson]), Dolichovespula maculata (L.), D. arenaria (F.), D. norwegica (F.)(=albida [Sladen]), and D. norvegicoides (Sladen). Workers and males of V. vulgaris were captured primarily in traps baited with the combination of acetic acid and isobutanol. Workers of V. acadica, V. consobrina, and V. rufa were captured primarily in traps baited with heptyl butyrate. Queens and workers of D. maculata were captured primarily in traps baited with acetic acid, or acetic acid plus isobutanol. The small numbers of D. arenaria, D. norvegicoides, and D. norwegica captured did not permit treatment comparisons. Season-long trapping indicated a presence of V. acadica, V. consobrina, and V. rufa workers from late June through July, D. maculata from early July into early August, and V. vulgaris from late July to early September. The earliest wasps captured were queens of V. vulgaris and D. maculata in late May, while the latest wasp captured was a worker of V. vulgaris the first week of October, in Palmer
Synergistic Trap Response of the False Stable Fly and Little House Fly (Diptera: Muscidae) to Acetic Acid and Ethanol, Two Principal Sugar Fermentation Volatiles
In an initial observation, large numbers of muscoid flies (Diptera) were captured as nontarget insects in traps baited with solutions of acetic acid plus ethanol. In subsequent field experiments, numbers of false stable fly Muscina stabulans (Fallén) and little house fly Fannia canicularis (L.) trapped with the combination of acetic acid plus ethanol were significantly higher than those trapped with either chemical alone, or in unbaited traps. Flies were trapped with acetic acid and ethanol that had been formulated in the water of the drowning solution of the trap, or dispensed from polypropylene vials with holes in the vial lids for diffusion of evaporated chemical. Numbers of both species of fly captured were greater with acetic acid and ethanol in glass McPhail traps, compared to four other similar wet trap designs. This combination of chemicals may be useful as an inexpensive and not unpleasant lure for monitoring or removing these two pest fly specie

Linguistic and (micro-)cultural differences in the global debate about re-naming 'schizophrenia': A mixed-methods survey from Switzerland
Background and hypothesis: This survey explores Swiss mental health professionals', users', and relatives' opinions on re-naming schizophrenia exploiting Switzerland's specific multilingualism to examine possible effects of linguistic and microcultural differences on the issue.
Study design: Opinions on 'schizophrenia' were collected using a self-rated online questionnaire incl. Freetext answers available in the three main Swiss languages, German, French and Italian. It was distributed to the main professional and self-help organizations in Switzerland between June and October 2021.
Study results: Overall, 449 persons completed the questionnaire, 263 in German, 172 in French and 14 in Italian. Of the total sample, 339 identified as mental health professionals, 81 as relatives and 29 as users. Considering the whole sample, almost half favored a name-change with a significant difference between stakeholder- and between language groups. Also, the name 'schizophrenia' was evaluated more critically than the diagnostic concept. Qualitative analysis of freetext answers showed a highly heterogenous argumentation, but no difference between language groups.
Conclusions: Our results suggest the attitude towards re-naming might itself be subject to (micro)cultural difference, and they highlight the nature of 'schizophrenia' as not only a scientific, but also a linguistic and cultural object. Such local factors ought to be taken into consideration in the global debate
Comparison of a Synthetic Chemical Lure and Standard Fermented Baits for Trapping Drosophila suzukii (Diptera: Drosophilidae)
We determined the attractiveness of a new chemical lure compared with fermented food baits in use for trapping Drosophila suzukii Matsumura, spotted wing drosophila (Diptera: Drosophilidae), in Connecticut, New York, and Washington in the United States and at Dossenheim in Germany. The chemical lure (SWD lure) and food baits were compared in two types of traps: the dome trap and a cup trap. Regardless of trap type, numbers of male and female D. suzukii trapped were greater with the SWD lure compared with apple cider vinegar (ACV) baits at the Washington and New York sites, and were comparable with numbers of D. suzukii captured with a wine plus vinegar bait (W + V) at Germany site and a combination bait meant to mimic W + V at the Connecticut site. Averaged over both types of attractants, the numbers of D. suzukii captured were greater in dome traps than in cup traps in New York and Connecticut for both male and female D. suzukii and in Washington for male D. suzukii. No such differences were found between trap types at the Washington site for female and Germany for male and female D. suzukii. Assessments were also made of the number of large (>0.5 cm) and small (<0.5 cm) nontarget flies trapped. The SWD lure captured fewer nontarget small flies and more large flies compared with ACV bait in New York and fewer nontarget small flies compared with W + V in Germany, although no such differences were found in Washington for the SWD lure versus ACV bait and in Connecticut for the SWD lure versus the combination bait, indicating that these effects are likely influenced by the local nontarget insect community active at the time of trapping. In New York, Connecticut, and Germany, dome traps caught more nontarget flies compared with cup traps. Our results suggest that the four-component SWD chemical lure is an effective attractant for D. suzukii and could be used in place of fermented food-type bait
