Insects have presented human society with some of its greatest development challenges by spreading diseases, consuming crops and damaging infrastructure. Despite the massive human and financial toll of invasive insects, cost estimates of their impacts remain sporadic, spatially incomplete and of questionable quality. Here we compile a comprehensive database of economic costs of invasive insects. Taking all reported goods and service estimates, invasive insects cost a minimum of US$70.0 billion per year globally, while associated health costs exceed US$6.9 billion per year. Total costs rise as the number of estimate increases, although many of the worst costs have already been estimated (especially those related to human health). A lack of dedicated studies, especially for reproducible goods and service estimates, implies gross underestimation of global costs. Global warming as a consequence of climate change, rising human population densities and intensifying international trade will allow these costly insects to spread into new areas, but substantial savings could be achieved by increasing surveillance, containment and public awareness.

French Polynesia is a veritable oasis of life, thousands of kilometers from the closest continent. The marine biodiversity is not itself exceptional, but the isolation of the Polynesia archipelagos has contributed to protecting resources and maintaining an abundant marine life. The clarity of the water contributes to the approachability of marine species. Observation of cetaceans by tourist operations began in the 1990s, and has now become a major commercial activity in French Polynesia.
