Walsh (1978) [10]Light trapsNONeed for more research in the area

Service (1979) [11]Light trapsYESNeed for research in this area

Thompson (1976) [12]Sticky traps, Fan traps, enclosure trap, slat trapYESVital findings on the importance of smell as attractants

Walsh (1980) [13]Sticky trapsYESOffered little promise in terms of replacing HLCs

Lamberton et al (2014) [14]Cow-baited tents, human odour baited tents, biconical traps, and electric trapsYES (human odour baited tents showed most promise)Setup too cumbersome. However, it demonstrated importance of smell as attractants in traps

Rodriguez-Perez et al (2013) [19]Verticle Bellac plaque, Esperanza Window Trap (original), BG Sentinel, Clear Window Trap, Esperanza Window Trap (modified), Horizontal Bellac Plaque and Human Silhouette TrapYES ( the Esperanza Window Trap was the most promising)EWTs though promising, still need some optimization

Toé et al (2014) [20]Esperanza Window Traps (original and modified designs)YESEWTs though promising needs some optimization

Hendy et al (2017) [21]Esperanza Window Trap (original and modified)YESEWTs though promising needs more optimization and testing in other countries
