Juvenile Stages

The largest of the stick insects, Megacrania alpheus Westwood, has paired thoracic glands which produce five volatile, protective chemicals. In response to irritation, five special odor compounds are ejected of which actinidine is identified as the major constituent by IR, NMR, and GC-Mass spectrometry and elemental analysis. Different juvenile stages contain varying amounts of actinidine. Few nymphs deprived of actinidine survive to maturity because of high incidence of mortality from natural predators.

General Method

The energy analysis of electrons scattered by a specimen in a scanning transmission electron microscope can improve contrast as well as aid in chemical identification. In so far as energy analysis is useful, one would like to be able to design a spectrometer which is tailored to his particular needs. In our own case, we require a spectrometer which will accept a parallel incident beam and which will focus the electrons in both the median and perpendicular planes. In addition, since we intend to follow the spectrometer by a detector array rather than a single energy selecting slit, we need as great a dispersion as possible. Therefore, we would like to follow our spectrometer by a magnifying lens. Consequently, the line along which electrons of varying energy are dispersed must be normal to the direction of the central ray at the spectrometer exit.
