+++ Bright fluorescence
++ Medium fluorescence
+ Low fluorescence
*Percentage is based on the number of crickets for which the tissues could be
analysed. In some circumstances, one or two of the above tissues may have been
absent from the cricket sections due to the processing and angle of cutting of the
longitudinal section of the cricket.
