Abstract Long-distance migration of insects impacts food security, public health, and conservation–issues that are especially significant in Africa. Windborne is a key strategy enabling exploitation ephemeral havens such as the Sahel, however, its knowledge remains sparse. In this first cross-season investigation (3 years) aerial fauna over Africa, we sampled flying 40–290 m above ground Mali, using nets mounted on tethered helium-filled balloons. Nearly half million were caught,...
The genus Abbrosoga Caldwell (Delphacidae: Delphacinae: Delphacini) was described in Martorell (1951) to include the single species errata Caldwell, 1951. Here, a second species, multispinosa n. sp. is described. Revised diagnostics are presented for and A. errata, including key species. A compiled list of 64 delphacid from Puerto Rico presented, with updated nomenclature, new record Delphacodes aterrima Rico.
An ongoing survey for novel phytoplasmas and viruses that affect palms (Arecaceae) is being conducted in Costa Rica along with potential vectors.

A key to genera represented in North and South America presented. compiled listing planthopper fauna includes 104 taxa (including new records 31 one subspecies). The findings underscore existence a rich, but understudied Belize.

This taxon associated with coconut (Cocos nucifera L.) and date palm (Phoenix L). The was detected Auchenorrhyncha surveys to find potential vectors lethal yellowing type syndrome. first report Sequence data mitochondrial cytochrome c oxidase subunit I (COI) barcoding region obtained accessioned into GenBank.
Myxia belinda gen. et sp. nov. is established for a new taxon of Cixiidae in the tribe Oecleini collected from palms Costa Rica. The was discovered while surveying potential phytoplasma vectors. Placement genus supported by 1,383 bp sequence 18S that differs 2.77% Haplaxius, 5.20% Myndus taffini, and 2.80% Nymphomyndus caribbea. Intrageneric variation found to be approximately 0.5% 0.6% within Haplaxius. Generic level differences COI ranged 15% 17% with novel differing about 16% other...
Melaniphax suffusculus gen. et sp. nov. is described from Costa Rica, representing the 57th delphacid species recorded country to date. The new genus superficially similar Caenodelphax Fennah in general appearance that body uniformly colored with wings infuscated. Distinctive features of taxon include simple, forceps-like gonostyli, a broadly compressed aedeagus large serrate lateral flanges, and anal tube bearing pair short, stout, truncate, caudally-directed processes on ventro-caudal...
A new species of cixiid planthopper (Hemiptera: Fulgoroidea) in the genus Oecleus Stål, mackaspringi sp. n., is described from Spring Garden, Jamaica. This taxon associated with coconut palm (Cocos nucifera L.) and was found while surveying plots active cases lethal yellowing (LY). first report Sequence data for COI gene 18S are also provided.
An ongoing survey for novel phytoplasmas and viruses that affect palms (Arecaceae) their potential vectors is being conducted in Costa Rica. During survey, a new species of derbid planthopper (Hemiptera: Fulgoroidea) from the palm Astrocaryum alatum H.F. Loomis was found Heredia State here described as Agoo dahliana sp. n. Omolicna dubia Caldwell O. latens Fennah were also on coconut (Cocos nucifera L.) represent country records. Sequence data cytochrome c oxidase subunit I (COI) generated 9...
An ongoing survey for planthoppers associated with palms in the Caribbean basin is being conducted current efforts on lowlands of Costa Rica. In an expedition June 2019, a derbid was found coconut Alajuela province and determined to be new species belonging genus Anotia. The novel taxon described named Anotia firebugia Bahder Bartlett sp. n. Additionally, molecular barcode data (COI) provided newly taxon.
ABSTRACT. In July and October 2023, two live triatomine bugs were found inside a home in New Castle County, Delaware. The identified as Triatoma sanguisuga , the most widespread bug species United States. is competent vector of Trypanosoma cruzi causative agent Chagas disease. specimens tested via real-time PCR (qPCR) for infection with T. one was positive. Despite being endemic to area, attainment accurate identification testing required multiple calls federal, state, private, academic...
The genus Haplaxius is a large taxon of cixiid planthoppers that economic importance due to the ability crudus transmit lethal yellowing in coconut palms. dougwalshi sp. n. established as new Cixiidae tribe Oecleini collected from native palms lowland tropical rainforest Costa Rica. Placement supported both by molecular evidence based on COI and 18S genes well morphological characters. This novel was discovered during survey work Rica look for phytoplasmas document planthopper diversity...
A new species of Myxia Bahder & Bartlett (Cixiidae: Cixiinae: Oecleini) is established as baynardi sp. n. collected from native palms in cloud forest habitat Costa Rica. Placement the genus supported by molecular analysis cytochrome c oxidase subunit I (COI) and 18S loci well morphological characters. Haplaxius delta (Kramer) was along Caribbean coast a country record for Based on characters observed COI 18S, H. herein moved to Myxia.
Haplaxius is a large genus of cixiid planthoppers that widespread in the New World and economically important due to role H. crudus transmitting palm lethal decline phytoplasmas. A new species Haplaxius, here described as pocococo sp. n., was discovered during survey work on palms north-central Costa Rica. Placement supported by sequence analysis COI 18S genes relative congeners morphological characters.
Recent survey work for planthoppers at La Selva Biological Station in Costa Rica found two new species allied with Cenchrea Westwood.

Both are described with illustrations, molecular identification given mtCOI gene sequence. modified key to genera also provided.
A new species of the genus Agoo Bahder & Bartlett, beani sp. n. was found associated with coconut (Cocos nucifera L., Arecaceae) in Jamaica. This discovered as part a survey Caribbean basin to document planthopper diversity on palms. Cytochrome c oxidase subunit I (COI) and 18S sequence data strongly support placement Agoo. The morphological features Omolicna cocoana Rodriguez-Leon Hidalgo-Gato from Cuba are reviewed this transferred into
Recent survey work on palms in Costa Rica has resulted the discovery of several new species Derbidae, especially Cenchreini. During a recent expedition, specimens collected by light trapping at Hotel Villa Blanca (cloud forest) were determined to be novel Omolicna Fennah. Sequence data was generated for taxon cytochrome c oxidase subunit I (COI) and 18S loci. Pairwise analyses phylogenetic support placement Omolicna.
