“…Molina et al (2008) showed that Lutzomyia fairtigi underwent a seasonal variation in the department of Casanare that was mainly determined by increased rainfall (ρ = 0.675; p < 0.001), whereas no changes in abundance or any association with environmental determinants were recorded for Lu. antunesi throughout the year.…”

Lutzomyia antunesi has been commonly reported in outbreaks of cutaneous leishmaniasis (CL) in the Orinoquia region of Colombia. The bionomics of this species were studied in the municipality of Villavicencio (Meta, Colombia). Sandflies were captured over the course of one week per month for one year in intradomiciliary, peridomiciliary and extradomiciliary housing areas. The captures were performed from 06:00 pm-06:00 am using CDC light traps and the females were processed for polymerase chain reaction (PCR) to detect Leishmania spp. A total of 22,097 specimens and 19 species were captured of which Lu. antunesi (89%) and Lutzomyia walkeri (5%) were the most abundant. Other species recognised as anthropophilic (Lutzomyia panamensis, Lutzomyia gomezi, Lutzomyia flaviscutellata and Lutzomyia fairtigi) were present in very low abundance (< 2%). Natural infection with Leishmania spp was detected using PCR in Lu. antunesi, Lu. panamensis and Lu. flavicutellata, showing infection rates of 1%, 4.8% and 7.5%, respectively. The present paper provides information on various ecological aspects of Lu. antunesi. An analysis of seasonality shows that this species increases in abundance in the hottest months (December, January and February), directly correlating with the maximum temperature and inversely correlating with precipitation. The natural infection rate is associated with the peaks of highest abundance.

“…For example, rain can destroy breeding sites and delay the development of sandflies in Iran. By contrast, findings in Colombia show a positive correlation between the prevalence of sandflies and rainfall (Molina et al ., ). However, previous studies have also proved the geographic distributions of phlebotomine sandflies to be influenced by meteorological factors (Bounoua et al ., ).…”

Phlebotomine sandflies (Diptera: Phlebotomidae) are vectors of the zoonotic disease leishmaniasis. To better understand the distribution of phlebotomine sandflies in order to facilitate control of leishmaniasis transmission, the present study explored the impacts of climate and landscape on local abundances of Phlebotomus chinensis in northwestern mainland China. Identification records were used to create a geodatabase for the locations at which P. chinensis had been collected in the region, and a regional-scale map was developed to show the distribution of P. chinensis. Location data and data on environmental factors during the years in which the samples were collected were incorporated, and a presence-only modelling method was used to evaluate the species' habitat preferences and to predict its potential distribution in northwestern mainland China. Jackknife analysis revealed that several meteorological variables, including maximum temperature in the warmest quarter, precipitation in the driest month, daily average temperature and daily precipitation, significantly affected the presence of this species. Moreover, the presence of P. chinensis was significantly associated with grassland and shrubland. Probability distributions using maximum entropy were used to map the distribution ranges of P. chinensis based on suitable habitats in northwestern mainland China. The models generated can be used to develop detailed strategies for the prevention and control of leishmaniasis.

“…A study in Colombia by Molina et al assessed the associations between climate phenomenon and the prevalence of sandflies using regression modelling. 22 Their results showed that there were strong positive associations between the presence of sandflies, maximum temperature and relative humidity. Cross and Hyams did a laboratory simulation test about the influence of temperature on sandflies, and according to this test all sandflies died within 2 h when temperatures exceeded 40 ∘ C. 23 It was also concluded that sandflies could hardly survive when the temperature is lower than 10 ∘ C. Larvae of sandflies are very sensitive to high temperature and low humidity, and die if the temperature is high and the humidity is less than 33%.…”

BACKGROUND Phlebotomine sandfly (Diptera: Psychodidae) is best known for its role as the vector of the leishmaniasis. Leishmaniasis is a global disease, currently known to be affecting 88 countries and 12 million people worldwide. RESULTS This study explored the impacts of climate factors and landscape on the local abundance of Phlebotomine sandfly in mainland China. A presence‐only modelling method was used to evaluate this species' habitat preferences from environmental factors. Jackknife analysis revealed that several biologically meteorological variables, including the maximum temperature of the warmest quarter, the precipitation in the driest month, the daily average temperature and daily precipitation, would significantly affect the existence of this species. Moreover, the existence of Phlebotomine sandfly was significantly associated with grassland and forest. CONCLUSION The results will improve scientific understanding of the risks of the spread of leishmaniasis over current infected areas and can be used to design more detailed surveillance programmes and more evidence‐based control planning for Phlebotomine sandfly and leishmaniasis. © 2019 Society of Chemical Industry
