摘      要：Three behaviors of epidemiological importance,namely feeding latency,feeding duration and defecation latency,for six populations of Meccus phyllosomus longipennis(Usinger)from areas of central,western and north-central Mexico with high(HP)and low(LP)prevalence of Trypanosoma cruzi(Chagas)human infection were evaluated in this *** median feeding latency(the time taken to begin feeding)was highly variable between ***-instar comparisons showed that at least 65%of the LP populations(N3 to adult)started to feed significantly(P0.05)later than the HP population,with N1 showing no difference,and N2 from LP populations feeding sooner than those from HP *** six populations had similar median feeding durations within instars.A higher(P0.05)percentage of the instars from HP populations defecated faster than the respective instars from the three LP *** 25%of the young nymphs(N1 to N3)and females in the HP populations defecated2 min postfeeding,compared with 4%-6%of the young nymphs and 1.3%-3%of females in the LP ***,17.7%-38.8%of the older nymphs(N4 to N5)in the HP populations and 6.8%-13.4%in the LP populations defecated during or immediately after *** results indicate that the HP populations have a greater potential than the LP populations to transmit *** infections,which may underlie the differences in the prevalence of *** infection in some areas where M *** is currently distributed.
