Due to significant Selection filters between generations, insects (have evolved to) need a very large number of individuals in each generation to survive as populations and species.
Large numbers of insects are detrimental to industrial lifestyles (agriculture, production, urban living).
Industrial lifestyles win – and don’t see that they are destroying there own foundations because insects have been rendered as “the other” like, but more than other, parts of nature (cf. the huge horror subgenre around them), and shut out of direct experience as something else than a nuisance.
