(19) and (22) to obtain stationary sequences of population structures Ut and reproductive value vectors Vt. Now the growth rate a = a(Bt) is a function of the sequence of random projection matrices. To examine elasticity is to examine the effect of a small change in the vital rates, ...
Moreover, population projection indicated that the G. legneri population can grow swifter when reared on E. ceratoniae than on E. kuehniella . Based on the experiments conducted to determine the larval stage preferences of G. legneri , for both hosts, larger larvae were more preferred stages...
