I don't know of an index codominance applied to insects. I carried out some searches on Google Scholar, but not found anything. Could someone please suggest some articles?
Perhaps you would like to provide a little more context to your question. Codominance is a term usually used in genetics, where two distinct alleles for a gene are expressed.
If you're interested about co-dominance of insect species in a community, i.e. two or more species that are equally dominant in a biotic community, the standard beta-diversity indices based on dominance and evenness would be the best bet to answer your research question. *i'm assuming you're doing a comparative communities between sites*
Simpson's index of dominance [p
2 ∗ n/(n − 1)] is perhaps one of the easiest to calculate. Simpson's is typically used as diversity index in with the formula [1 - p
2 ∗ n/(n − 1)], which is essentially the inverse of the index of dominance.
Other indices worth considering would be Shannon-Weiner, Hill's number,
Personally, I wouldn't calculate indices directly. Species-abundance curves and models would probably do a better job to describe the community, and provide better exploration potential for other more appropriate analyses.
Adam Quek, thanks. The codominance is used in Ecology too, the Simpson's index its very nice, but I need of other indexes.
