Abstract

The element contents of Trogoderma granarium Everts diapaused and
nondiapaused larvae reared on three iarval hosts and kept at two degrees of
temperatures. Analyses of 10 elements Na,Mg,Si,P ,S,CI,K,Ca,Cu and Zn were
analyzed by energy dispersive X-ray analyzer (EOX). It was observed that the most
abundant light element in (NOLW) and (NOLC) was K. The most abundant light
element in NOLP was P. Sodium was disappeared from NOLWand NOLC, while it
was appeared in significant values in OLW kept at 25°C and OLW kept at 35°C. Mg
disappeared only from NOlW. Heavy metals (Cu and Zn) show relative abundance
OLW kept at 25 and 35cC less than their control (NOlW). The same trend was
observed in OlC and OlP except those reared on peanut and kept at 25°C.
