List of entomology societies worldwide.

An international organization formed to advance the science of nematology in both its fundamental and economic aspects.

A nonprofit entity comprised of members who have an interest in the study of plant-parasitic, free-living and insect-parasitic nematodes. ONTA now has over 400 members worldwide. Membership is open to all individuals and companies that share an interest in subtropical and tropical Nematology.

Aims to foster communication among nematologists worldwide, through national and regional nematology societies. It also aims to enhance overall awareness of nematodes and the science of nematology.

This comprehensive guide attempt to organize the thousands of informational resources available to entomologists. The original compilation was done in the early 1990's by L.B. Bjostad of Colorado State University and John VanDyk of Iowa State University.

A collaborative effort between scientists from around the world, aiming at providing the best possible access to the wealth of information on ants, to fulfill the conservation needs of the International Union for the Study of Social Insects (IUSSI), and the Species Survival Commission of the World Conservation Union (IUCN).

UK's Natural History Museum brings together an enormous body of information on what the world's butterfly and moth (Lepidoptera) caterpillars eat.

Sponsored by the USGS, this database is a "work in progress," consisting of information on the known distribution of Dragonflies and Damselflies (Odonata) in the United States. Distribution maps and county checklists were created by extracting information on Odonata distribution from publications listed in references.

This website publishes survey maps for pests of agricultural and forest commodities and provides links to pest news and information. The National Agricultural Pest Information System (NAPIS) stores and manages pest survey data that is collected by CAPS and other PPQ survey programs. Detection surveys are one tool used to manage the introduction of exotic pests.

Names insect champions and documents their achievements. Each chapter deals with a different category of record.

To produce basic and applied information about plant-and fungal-related topics. This aim is carried out through science and research in systematics, biological interactions, economic botany, conservation and horticulture.

Provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories.
