Bottom Line: Results of the Pearson chi-squared test (χ2) showed a positive association between CDC-LT and species of Culicini and Uranotaeniini tribes.Additionally, our results suggested a positive association between CDC-A and representatives of the Culicini and Aedini tribes, whereas the MMI was positively associated with the Mansoniini and Sabethini as well as with Anophelinae species.Results of the present study showed that MMI performed better than CDC-LT or CDC-A in sampling mosquitoes in large numbers, medically important species and assessing diversity parameters in rural southeastern Atlantic Forest.

ABSTRACT
Traps are widely employed for sampling and monitoring mosquito populations for surveillance, ecological and fauna studies. Considering the importance of assessing other technologies for sampling mosquitoes, we addressed the effectiveness of Mosquito Magnet® Independence (MMI) in comparison with those of the CDC trap with CO2 and Lurex3® (CDC-A) and the CDC light trap (CDC-LT). Field collections were performed in a rural area within the Atlantic Forest biome, southeastern state of São Paulo, Brazil. The MMI sampled 53.84% of the total number of mosquitoes, the CDC-A (26.43%) and CDC-LT (19.73%). Results of the Pearson chi-squared test (χ2) showed a positive association between CDC-LT and species of Culicini and Uranotaeniini tribes. Additionally, our results suggested a positive association between CDC-A and representatives of the Culicini and Aedini tribes, whereas the MMI was positively associated with the Mansoniini and Sabethini as well as with Anophelinae species. The MMI sampled a greater proportion (78.27%) of individuals of Anopheles than either the CDC-LT (0.82%) or the CDC-A traps (20.91%). Results of the present study showed that MMI performed better than CDC-LT or CDC-A in sampling mosquitoes in large numbers, medically important species and assessing diversity parameters in rural southeastern Atlantic Forest.

Mentions: To address the diversity of culicids per trap, only individuals identified to thespecies level were considered. The results of the KW test indicated that the observeddifferences between the Rényi diversity index (Fig.3) were statistically significant only as regards richness (KWχ2 =19.338; p = 6.321 E-05). The results of the Bonferroni test indicated that the MMIpresented a significant difference as compared to the CDC-LT (p = 6e-05) and the CDC-A(p = 0.0012). However, the CDC-A showed no significant difference (p = 0.6059) comparedwith the CDC-LT. The other Rényi diversity index were not statistically significant,Shannon-Weiner (KWχ2 = 0.9298; p = 0.6282), Simpson-Yule (KWχ2 =2.3813; p = 0.304) and Berger-Parker dominance (KWχ2 = 3.4419; p = 0.1789).The expected values obtained by the bootstrap analyses were closer to the observedrichness in the MMI data because the species captured represented 88.7% of the expectedspecies (Sobserved = 44; bootstrap = 49.6). The CDC-LT was able to sample83.5% (Sobserved = 44, bootstrap = 52.7) and the CDC-A 76.7%(Sobserved = 33, bootstrap = 43) of the expected species. The MMI andCDC-LT traps presented the same number of species, with some species common to bothtraps and other species that were captured by one specific trap. The Cj (0.57) and theCn (0.72) values showed similarities between species captured by the CDC-A and MMI traps(Supplementary data 1). The Venn diagram (Fig. 4)illustrated species distribution in each trap, as well as those that were shared by twoor three traps. The complete list of species is in the Supplementary data 2.
