Chitobiase activity was observed in mesocarp and exocarp cantaloupe tissue, with the highest activity in fruit mesocarp. Acetone precipitated proteins were applied to an anion and cation exchange column. Two peaks were observed. The anionic peak had the most activity and the fraction was applied to a size-exclusion column with showed on peak of chitobiase activities. Horizontal image resolution of about 10 cm on the ground is typical.
Aerial surveys are relatively non-intrusive.
Poly IR lenses and filters were donated by Fresnel Technologies, Ft. Worth, TX, and aircraft costs were supported by the first author. A microplate assay for release and measurement of histamine has been developed as reported previously. The data is normally distributed as ascertained by descriptive analysis and the Komogorov-Smirnov test. Positional bias for samples on the microplate was shown to be absent.
