- A searchable database to planthopper literature from ca 1940 to present – follow this link (it is entitled “Delphacid Research Bibliography Database” but it is all Fulgoromorpha, I simply do not have access to edit the title). This searchable database includes 12,538 citations and 5,557 PDFs online (as of Aug. 2019).
- For older literature (pre-1940), I have a PDF library posted here. The digital library includes close to 650 pre-1940 PDFs to planthopper literature (and occasionally other hemipteran taxa), many of which are also linked to Biodiversity Heritage Library, but these links are incomplete. I have many to add (both PDFs and links)….
- For a searchable database for older literature, see DrMetcalf at North Carolina State University. DrMetcalf is an online version of the combined bibliographies of the Metcalf Catalog.
- I have begun posting Recent Planthopper Literature here.

Note on the Searchable Database:
The planthopper searchable bibliography began with Delphacidae and subsequently expanded to include all Fulgoromorpha (i.e., all taxa within the infraorder, including in taxa transferred out of the Fulgoromorpha). Similarly, the bibliography started with just taxonomy-related literature and has expanded to include ‘all’ literature. I have only included literature after 1940 so that this bibliography is largely complementary to Dr. Metcalf (I know there are a few pre-1940 references, these are mostly deliberate).
Generally, the searchable database is supposed to include:
- All peer-reviewed, published literature (post 1940) that impacts planthopper nomenclature (species descriptions, revisionary taxonomy, phylogenetics), including host, parasite or other biotic interactions (endosymbionts, plant pathogen vectors, etc.), physiology, toxicology and so on. Literature that provides geographic records (i.e., lists of species) or host records (lists of species from plants) are explicitly included.
- Lately I have begun to include papers on Dryinidae, Mymaridae, Pteromalidae, Eulophidae, Strepsiptera, etc., where planthoppers serve as hosts AND the host is explicitly mentioned. (Papers were the host is not noted are not included). This effort is nascent, so a lot has been missed, so far.
- I am now including literature on planthopper-vectored plant diseases if the vector is mentioned.
- All published primary literature where a planthopper name is in the paper title or key words.
- All phylogenetic works including the Hemiptera that include references to planthoppers (even when they are the outgroup), although I may exclude papers treating insects on (e.g.,) the ordinal level, especially where planthoppers are not explicitly mentioned.
- Discussion of planthoppers in the context of a biological phenomenon (e.g., on migration, wing polymorphism or as plant pathogen vectors). Papers that merely mention a planthopper species are generally not included (at least not intentionally).
- Theses and dissertations are included.
- Books on planthopper taxonomy or identification are included. Technical books that are individually authored by chapter are referenced for each chapter.
The database is strongest in taxonomic literature for planthoppers; in contrast, economic literature – especially non-English works – is still a developing area.
For ‘gray literature’ – papers that are not explicitly peer-reviewed, including documents, pest alerts, popular literature, textbooks. Because such literature is not reliably indexed, its inclusion is haphazard as it comes to my attention (also, it is not my intention to survey unpublished materials, but I will include the ones I find that I deem useful and citable).
- Abstracts of scientific meetings are included, if citable (i.e., the work provides author, title, abstract, name and dates of meeting, pagination.
- Government documents and documents produced by private organizations or companies are included as long as they include sufficient information to be citable.
- Websites are not included, even if citable.
- Popular literature and textbooks are not included (exceptions are made if the work describes biological interactions or includes compelling graphics)
- Pest alerts for planthoppers are included as long as they are sourced and are citable. Pest alerts for planthopper-vectored diseases are included if the planthopper vector is noted.
- Self-published works may be included if they are citable.
- Newsletters (e.g., Ledra, IRRI newsletter) are included when available and citable.
