Abstract
Armored scale insect species from coconut palms and the undergrowth plants in selected areas in Laguna and Quezon were collected. Seven species were identified from coconut, lanzones, atis, avocado, banana, mangosteen and orchid. Wings of male armored scale insects were mounted in slides and analyzed for character variations of venations, microtrichia, venation hairs and light interference pattern. Results showed a reduction on the wing venation, widely distributed microtrichia and long and thick venation hairs. Microstructures like microtrichia together with the uneven membrane thickness affected the color variation and shape of pattern of the wings. The intensity of light received were considered as well as the background where the patterns were displayed. Wing Interference Pattern (WIP) differed in terms of the abundance of blue to purple color and yellow to orange or green color. Three color wing interference patterns were determined. The study showed that WIP were significant in determining the generic level of armored scale insects. The results of the study enabled the construction of taxonomic key for genera.
