Toxicity of isocycloseram, an isoxazoline insecticide, against laboratory and field-collected German cockroaches (Blattodea: Ectobiidae).

Isocycloseram is a new insecticide in the isoxazoline class that targets insect GABA-gated chloride channels. In this study, we evaluated a cockroach gel bait formulation containing 1% isocycloseram against a susceptible strain (UCR) and 5 field-collected strains (WM, RG386, Ryan, CDR, and SY) of the German cockroach, Blattella germanica (L.) (Blattodea: Ectobiidae), and compared it with several commercial insecticide baits in the laboratory. Using the Ebeling choice box method, we also tested a residual deposit of an SC formulation of isocycloseram against the UCR, RG386, and Ryan strains. The isocycloseram bait was among the fastest-performing treatments against adult males (mean survival time: 0.9-2.7 days) and mixed stages and sexes (mean survival time: 1.4-5.4 days) across all strains. Secondary transfer effects of the bait were demonstrated in the UCR strain by exposing new adult males to individuals killed by direct bait treatment. Physiological resistance was not detected in the WM, CDR, and RG386 strains with topical treatment of a diagnostic dose (3× LD95) of isocycloseram developed using the UCR strain. However, topical assays revealed resistance ratios (RR50) of 1.6 and 3.0× in the Ryan and SY strains, respectively. The performance of a 0.05% isocycloseram residual application against the Ryan strain was improved with the addition of piperonyl butoxide.

Crossing the Split in Nepantla: (Un)successful Attempts to Dismantle a TESOL Teacher Candidate in After-Queer Research.

This paper neither plans to use the restorative agenda nor provides a sample of representation or voices of a teacher candidate or researcher who identifies themselves as queer. Instead, this paper looks into the researcher's desires and imagining in analyzing a split self to think about how to problematize their thinking and actions, which should go beyond the limits of gender and sexuality or a coded term "L-G-B-T-Q," to disrupt the existing binary of doing queer research. First, the author reviews what queer and after-queer mean in educational research and how the researchers have queered their work in the education field. Then, the author describes the nepantla concept as a theoretical lens. The autohistoria-teoria, or a personal essay that theorizes, is used as a form of self-critique in this piece. The author concludes by reexamining this paper's central question, How did a Teaching English to Speakers of Other Languages (TESOL) teacher candidate queer their teaching in a high school in the United States? and shares critical thoughts of what could be next in after-queer research.
