The diel biting periodicity of the arbovirus vector Culex (Melanoconion) caudelli Dyar and Knab (Diptera; Culicidae) in the Aripo-Wallerfield forest, Trinidad, was studied by collecting mosquitoes attracted to mouse-baited traps at 2-hourly intervals during eight 24 h periods. Biting females of Cx caudelli were collected during all night-time hours, 18.00-06.00 hours, with an overall unimodal pattern, i.e. one well-defined peak between 22.00 and 04.00 hours. This contrasts with previous reports that Cx caudelli is diurnally active. During the four moon phases, the period of peak biting activity varied from 22.00 to 24.00 hours at fullmoon, from 22.00 to 04.00 hours at first quarter, and from 24.00 to 02.00 hours at new moon and last quarter phases. The number of mosquitoes collected varied significantly with moon phases, the highest (152/24 h) being collected in the first lunar quarter and the lowest (71/24 h) in the last lunar quarter. Cloud cover and rainfall had no significant effect on the diel biting periodicity of Cx caudelli.

“…Agricultural zones (habitat located in the highlands) of Galápagos are particularly associated with A. taeniorhynchus, possibly related to breeding site availability from water provision for livestock or from the heavier rainfall that occurs in the Galápagos highlands33. Darker lunar phase has been shown elsewhere to augment light-trap catches of mosquitoes50. Although A. taeniorhynchus is the predominant mosquito across the Galápagos Islands, 12% of mosquitoes captured during longitudinal monitoring were Culex quinquefasciatus, which we have already shown to be a moderately competent laboratory vector of WNV3 and in southern USA states this species is a renowned WNV vector.…”

Increased connectivity with the mainland has led to the arrival of many invasive species to the Galápagos Islands, including novel pathogens, threatening the archipelago's unique fauna. Here we consider the potential role of the mosquito Aedes taeniorhynchus in maintaining the flavivirus West Nile virus [WNV] should it reach the islands. We report on three components of vectorial capacity - vector competency, distributional abundance and host-feeding. In contrast to USA strains, Galápagos A. taeniorhynchus is a competent and efficient WNV vector, capable of transmission at 5 days post-exposure. Based on 25 blood-meals, mammalian feeding suggests a potential bridge vector role should contact with key amplification taxa occur. Vector population abundance is driven primarily by climatic factors, peaking between January and March. As a ubiquitous competent vector, A. taeniorhynchus may facilitate future WNV establishment, therefore it is vital to ensure the biosecurity of Galápagos to prevent introductions of pathogens such as WNV.

“…Suction trap ca,tches do not (Williams, Singh and El Ziady, 1956). A similar effect of moonlight has also been recorded in light trap catches of mosquitoes by Provost (1959). The variability in the catches of the light trap is caused by competition with a moon of given phase appearing in the sky either a t different times or for different lengths of time (Williams, 1936).…”
