[6] [65] While noting population increases for certain species of insects in particular areas, the authors reported an annual 2.5% loss of biomass. They wrote that the review "revealed dramatic rates of decline that may lead to the extinction of 40% of the world's insect species over the next few decades", [6] [66] a conclusion that was challenged.

In contrast, the bee population worldwide has been increasing steadily since 1975, based on honey production, with China responsible for most of the growth. [14] The period of time with the lowest growth in worldwide honey production was between 1991 and 1999, due to the economic collapse after the dissolution of communism in the former Soviet ...

With the decline of both wild and domestic pollinator populations, pollination management is becoming an increasingly important part of horticulture.Factors that cause the loss of pollinators include pesticide misuse, unprofitability of beekeeping for honey, rapid transfer of pests and diseases to new areas of the globe, urban/suburban development, changing crop patterns, clearcut logging ...
