Ovicidal activity of juvenile hormone mimics in the bean bug, .

Insect juvenile hormone (JH) mimics (JHMs) are known to have ovicidal effects if applied to adult females or eggs. Here, we examined the effects of exogenous JHMs on embryonic development of the bean bug, . The expression profiles of JH early response genes and JH biosynthetic enzymes indicated that JH titer was low for the first 3 days of the egg stage and increased thereafter.

Preparation of thin-film electrolyte from chitosan-containing ionic liquid for application to electric double-layer capacitors.

A novel thin-film electrolyte (TFE) based on chitosan (CS) with 1‑ethyl‑3‑methylimidazolium tetrafluoroborate (EMImBF) was prepared by a new procedure for use as a solid electrolyte in electric double-layer capacitors (EDLCs). In this system, EMImBF plays important roles as both a dissolving solution and a charge carrier for EDLC application. By analyzing and characterizing the obtained products, the CS-TFEs showed a surface without CS/EMImBF phase separation and with high thermal stability and good tensile properties.
