Abstract
The impact of insect infestation on several biotic and abiotic variates in 3 small bulk-wheat ecosystems was studied by measuring these variates at monthly intervals during 1969–1970. One ecosystem was insect-free, the second was artificially infested with Cryptolestes ferrugineus and Oryzaephilus surinamensis, and the third with Sitophilus granarius and Tribolium castaneum. The relationships between 8 environmental and 8 entomological and microbial variates were examined by canonical correlation analyses. The degree of predictability (R c 2 ) of the first pair of canonical variates in the 3 ecosystems ranged from 80% to 95%. The first 2 pairs of canonical variates were highly significant in all 3 analyses (P
