Citrus ID vs Odonata Central

Citrus pests and diseases may be found on a number of plant species in various plant families. The Citrus ID Key is primarily intended to help people working or conducting pest surveys in citrus orchards, variety collections, and home gardens, so its focus is limited exclusively to the citrus family (Rutaceae). Although eight genera of Rutaceae are native to the continental United States (Amyris, Choisya, Cneoridium, Esenbeckia, Helietta, Ptelea, Thamnosma, and Zanthoxylum), most of these are unlikely to be encountered in our target locations and can be keyed using regional guides. The cultivars and taxa of citrus and relatives that have been introduced and released for cultivation are the most likely to be encountered in cultivated settings, so the Citrus ID Key concentrates on these taxa. Cultivars of citrus and its relatives are released in the United States through state agencies and to a lesser extent the USDA-ARS National Clonal Germplasm Repository for Citrus & Dates. Our target list of entities was synthesized from the cultivar lists provided by the California Citrus Clonal Protection Program, the Florida Citrus Arboretum, the Florida Chiefland Budwood Distribution Center, the Florida Bureau of Citrus Budwood Registration, and the Texas Budwood Certification Program. Arizona no longer certifies budwood, instead relying on the California program. The resulting target list includes over 500 entities of citrus and relatives cultivated in the United States. Field identification to the level of cultivar remains impossible in most cases. This is partially due to the complicated reticulate breeding history of citrus, but also, selection has generally focused on characters such as taste, disease and stress resistance, and fruiting phenology rather than on characters of ornamental (and thus morphological) value. This key facilitates identification to at least the cultivar group level within citrus (e.g., sweet oranges, sour oranges, etc.), if not beyond for select cultivars.

Easily keep track of all your sightings of Dragonflies and Damselflies (odonates) and contribute to citizen science. This app allows you to create checklists of all your odonate sightings on your phone and then upload them to Odonata Central website, including species seen, abundance, date and location. Later you can view these observations on the Odonata Central website, along with those of thousands of other users, as maps and species lists. Odonata Central is a citizen science project that collects user observations of odonates, primarily from the western hemisphere, to contribute to understanding their distribution, biogeography, biodiversity, and identification. This app is for users who are able identify most of the odonates of their region. If you need help identifying Odonates, see our companion app, Dragonfly ID. Features: - Presents a checklist of possible species based on your location. - Supports four languages (English, Spanish, Portuguese and French) and is primarily intended for use in the Western Hemisphere. - Easily toggle between display of English and Scientific names. - Easily assign a location by using the favorite locations you have stored on Odonata Central, use your current phone location or choose a location from a map. - Convenient offline mode that allows you to enter your observations when you do not have a cell phone signal. You create and store your checklists on your phone and add your location later when you have a signal. Note that the app does not accept photos. Those can be added later by editing your checklist on the Odonata Central website. This is a helper app for the Odonata Central website. You must have an Odonata Central account and you can register for one from the app or the website.
