Redescription of immature stages of Culicoides paraensis (Goeldi) (Diptera: Ceratopogonidae), vector of the Oropouche virus.

Oropouche fever is an emerging zoonotic disease caused by Oropouche virus (OROV). It has two distinct transmission cycles, with the anthropophilic biting midge Culicoides paraensis (Goeldi) (Diptera: Ceratopogonidae) being the primary vector in the urban cycle. Species identification of Culicoides typically has been carried out on the basis of morphological characters, but molecular tools applied to taxonomy can provide rapid and efficient methods to the identification of vector species.

Rapid and Efficient Detection by PCR of Culicoides insignis (Diptera: Ceratopogonidae), the Main Vector of Bluetongue Virus (BTV) in the Neotropical Region.

Bluetongue virus (BTV) causes a viral, non-contagious disease that mainly affects sheep, cattle, and wild and farmed ruminants causing damage to these animals and significant economic losses. Culicoides insignis Lutz, the major BTV vector in South America, is one of the most abundant species in Argentina and commonly associated with cattle farms.

Significant reduction in abundance of peridomestic mosquitoes (Culicidae) and Culicoides midges (Ceratopogonidae) after chemical intervention in western São Paulo, Brazil.

Background: We assessed the impact of two sand fly insecticide interventions (insecticide spraying and insecticide-impregnated dog collars) on the peridomestic abundance and distribution of mosquitoes (Culicidae) and biting midges (Ceratopogonidae) in western São Paulo (Brazil) in a long-term (42-month) evaluation. Both of these dipteran groups are vectors of diseases of medical and veterinary relevance to humans and domestic animals in Brazil.

Methods: The interventions in the 3-arm stratified randomised control trial were: pheromone + insecticide (PI) (chicken roosts were sprayed with microencapsulated lambda-cyhalothrin; pheromone lure has no effect on the Diptera pests studied here); dog-collars (DC) (dogs fitted with deltamethrin-impregnated collars); and control (C) (unexposed to pyrethroids) were extended by 12 months.

Floral Odors and the Interaction between Pollinating Ceratopogonid Midges and Cacao.

Most plant species depend upon insect pollination services, including many cash and subsistence crops. Plants compete to attract those insects using visual cues and floral odor which pollinators associate with a reward. The cacao tree, Theobroma cacao, has a highly specialized floral morphology permitting pollination primarily by Ceratopogonid midges.
