WINGS OF RED PALM WEEVIL (RPW) AND THEIR BEHAVIOR AS SEMICONDUCTOR

Studies on wings of red palm weevil (RPW), Rhynchophorus ferrugineus, showed that elytron and hind wings have tapered, papillae structures that are distributed in array. By using EDAX analysis we found that the elytron of the insect composed of different elements mostly transient elements composed of a combination of C, Cl, Fe, Cu and Re materials with percentages ~75.8, 2.8, 3.3, 10.2 and 7.8% respectively. The EDAX analysis of the insect hind wing showed that the hind wing is composed of a combination of C, Cu, K, Zn and N materials with percentages ~12.7, 46.5, 1.2, 17.4 and 22.2% respectively. While the EDAX analysis without using gold as adhesive showed that the elytron has (C, O, Cl, K, Cu) with percentages of 70.92, 27.67, 0.32, 0.38 and 0.71 respectively, and the hind wing contains C, O, Si, P, Ca, Cu with the percentage of 64.49, 32.02, 0.12, 0.22, 2.80 and 0.35 respectively.
Potassium (K) was found in the elytron in the form of K MAD and this element has a photoelectric effect and means that the elytron needs any light to have energy that affects K. While the hind wing needs light and temperature hence its composition contains P in the form of GaP and Si in the form of SiO₂. Si would be the main component of the solar system and P would be behave as semiconductor. So, wings of RPW showed to have a photo-energy effects and semiconductor behaviour.
