“…Sugar solutions fermented by Bakers’ yeast (sugar/yeast mixtures [SYM]) were demonstrated to be attractive to Anopheline mosquitoes in Tanzania [35]. We have previously demonstrated the efficacy of both SYM and chemiluminescent light-sticks as attractants for phlebotomine sand flies in Ethiopia and in Israel using horizontal sticky traps [36]. Here, we combined these attractants with inverted up-draft suction traps similar to CDC traps but fabricated in our laboratory and designed to operate on 2 AA type rechargeable batteries (3 V).…”

BackgroundVisceral leishmaniasis (VL) known as Kala-Azar is a serious systemic disease caused by Leishmania donovani parasites (Trypanosomatidae: Kinetoplastida). The disease is prevalent in the Indian Sub-continent, East Africa and Brazil. In Africa, the worst affected regions are in Sudan, with an estimated 15,000-20,000 cases annually and Ethiopia with 5,000-7,000 cases a year. The main vector of VL in Sudan and Northern Ethiopia is Phlebotomus orientalis, a sand fly frequently found in association with Acacia spp and Balanite spp woodlands.MethodsTo optimize sampling of sand flies for epidemiological studies in remote areas we tested different means of attraction. Miniature suction traps employing 2AA batteries (3 V) were deployed in the up-draft orientation and baited with chemical light-sticks (Red, Yellow and Green), or bakers’ yeast in sugar solution (emitting CO2 and perhaps other attractants). These traps were compared with standard CDC incandescent light traps employing 6 V batteries. Trials were conducted during two consecutive years at different localities around Sheraro, a town in West Tigray, Northern Ethiopia.ResultsThe sand fly species composition was similar but not identical in the different locations tested with different Sergentomyia spp. predominating. Phlebotomus spp. comprised less than 1% of the catches during the first year trials (November – December 2011) but increased markedly during the second year trials performed later in the dry season at the height of the sand fly season in February 2012. Although there did not appear to be a species bias towards different light wave-lengths, fermenting yeast in sugar solution attracted relatively more Phlebotomus spp. and Sergentomyia schwetzi.ConclusionsAlthough the standard 6 V CDC incandescent light traps captured more sand flies, light-weight (~350 g) 3 V suction traps baited with chemical light-sticks were shown to be effective means of monitoring sand flies. Such traps operated without light and baited with yeast in sugar solution caught relatively more Phlebotomus spp.

“…These 3 V traps are not equipped with incandescent lights because 2 AA batteries do not provide sufficient power to run both motor and light for 12 hours. Therefore, to experiment with light traps we utilized chemiluminescent light-sticks to attract the sand flies to the 3 V traps [36]. …”

“…Sticky traps have been reported to be an effective collection and sampling method for Old World phlebotomine sand flies (Alexander 2000;Burkett et al 2007;Veronesi et al 2007;Moncaz et al 2012Moncaz et al , 2013. In the neotropical New World fauna, few studies (Thatcher andHertig 1966, Ferro et al 1995) have reported their usefulness.…”

“…It is uncertain as to whether or not the height at which sticky panels were placed might have been an influencing factor. In a study conducted in the Old World, it was reported that sticky traps placed at 10 cm above the ground and supplemented with CO 2 (dry ice or yeast fermentation) were effective to collect phlebotomine sand flies (Moncaz et al 2013). Sticky traps have also been useful in detecting reproductive and breeding places (Moncaz et al 2012).…”

“…The sticky trap has been evaluated under field conditions with a variety of designs. For instance, sticky traps were evaluated with blue and yellow colors baited with synthetic sex pheromones (Bray et al 2010), host odor (Oshaghi et al 1994), CO 2 in horizontal position (Moncaz et al 2013), or with CO 2 paired with a metofluthrin (Zollner and Orshan 2011), and colored chemical light sticks (Burkett et al 2007), with and without lights (Veronesi et al 2007). Another method of capture is the delta trap, which is mainly used for economically important insects, usually combined with sex pheromones (Barrera et al 2006).…”

Phlebotominae are the vectors of Leishmania parasites. It is important to have available surveillance and collection methods for the sand fly vectors. The objectives of the present study were to evaluate and compare traps for the collection of sand fly species and to analyze trap catches along months and transects. Field evaluations over a year were conducted in an endemic area of leishmaniasis in the state of Quintana Roo, Mexico. A randomized-block design was implemented in study area with tropical rainforest vegetation. The study design utilized 4 transects with 11 trap types: 1) Centers for Disease Control and Prevention (CDC) light trap with incandescent bulb (CDC-I), 2) CDC light trap with blue light-emitting diodes (LEDs) (CDC-B), 3) CDC light trap with white LEDs (CDC-W), 4) CDC light trap with red LEDs (CDC-R), 5) CDC light trap with green LEDs (CDC-G), 6) Disney trap, 7) Disney trap with white LEDs, 8) sticky panels, 9) sticky panels with white LEDs, 10) delta-like trap, and 11) delta-like trap with white LEDs. A total of 1,014 specimens of 13 species and 2 genera (Lutzomyia and Brumptomyia) were collected. There were significant differences in the mean number of sand flies caught with the 11 traps; CDC-I was (P = 0.0000) more effective than the other traps. Other traps exhibited the following results: CDC-W (17.46%), CDC-B (15.68%), CDC-G (14.89%), and CDC-R (14.30%). The relative abundance of different species varied according to trap types used, and the CDC-I trap attracted more specimens of the known vectors of Leishmania spp., such as like Lutzomyia cruciata, Lu. shannoni, and Lu. ovallesi. Disney trap captured more specimens of Lu. olmeca olmeca. Based on abundance and number of species, CDC light traps and Disney traps appeared to be good candidates for use in vector surveillance programs in this endemic area of Mexico.

BackgroundIn Lupoid Leishmaniasis, erythematous to brown papules often occur around a central old scar, which can expand over time. For unclear reasons, these lesions tend to develop on the facial area.ObjectivesThis study was conducted to study the distribution of Lupoid Leishmaniasis lesions on the face and compare them with those of acute leishmaniasis.MethodsThis case‐control study included 100 patients with the acute type of cutaneous leishmaniasis and Lupoid Leishmaniasis who were referred to the dermatology clinics of Ghaem and Emamreza hospitals. We recorded lesion morphology, demographic data and locations of lesions on the face.ResultsWe enrolled 55 patients with acute leishmaniasis and 45 patients with Lupoid Leishmaniasis, with a mean age of 21.30 ± 20.71 years. There were no significant differences in age (p = 0.78), gender (p = 0.48), and the distribution of lesions on different anatomical areas (p = 0.22) between the two groups. In both groups, the involvement of the zygoma was significantly higher than in other areas on the face (p = 0.001).ConclusionsOur study reveals that the anatomical location does not play a role in lesion evolving into Lupoid form.
