I conducted a research in to elucidate the biology a of an insect seed predator that infest seeds of a palm specie in cloud forest in Venezuela. I did collected seeds directly from the palm and seeds picked up from the forest floor in two localities. I want to know if differences exists between localities with respect to where insects collocate their eggs (seeds in plant or seeds in forest floor).

I tried to resolve this question by a contingency table analysis, but I have two questions

1) A reviewer criticize my samplings design because is not balanced (26 vs 176 seeds in Avila site). Although I think that unbalanced design is not a restriction in contingency table analysis (but small expected values are). Is that correct?

2) I will test for independence between place of oviposition and Infestation in each locality by Ji-squared analysis. But I could compare probabilities of insect infestation in plant or forest floor between sites in an only analysis? A logistic regression could be a valid method? Odds ratio?
