The optimum carrying capacity for the 100-cm3 chambers was 22 +/- 2 females. In the 20-50 female chambers, the number of eggs ranged from 420 to 699, and adult production from 306 to 432. In the chambers containing 1-20 females, egg number and realized adult progeny increased linearly to reach an asymptote. Female mortality began to increase substantially in the 26-female chamber, from 5.7% to 15% and finally reaching 60.2% in the 46-50 female chambers.
The following parameters were recorded for each experimental chamber (three replicates): (1) female mortality without oviposition, (2) number of eggs oviposited and (3) number of adults emerging from the egg cohort. Laboratory conditions were maintained at 23-26 degrees C and 85-95% RH. serrana engorged females and an equal number of males. Rearing chambers of 100 cm3 were populated with 1-50 L. To do this, the experimental carrying capacity of a standard rearing chamber was determined, i.e., the optimum population size in relation to density (individuals per unit of space). The phlebotomine sand fly Lutzomyia serrana (Damasceno & Arouck) was mass-reared tinder conditions of varying densities in an effort to improve colony production efficiency.
SantamarÃa, Erika Munstermann, Leonard E Ferro, Cristina There was an increase in the demand for mental health visits, and theĮstimating carrying capacity in a newly colonized sand fly Lutzomyia serrana (Diptera: Psychodidae). It was also observed that the proportion of visits due to mental health disorders increased after the event in the "Região Serrana", as well as the number of mental health care visits per CAPS.  DISCUSSION  In conclusion, we observed that the 2011 Landslides in "Região Serrana" led to a sustained higher burden to public mental health care.  RESULTS  We observed that there was an important increase in the rate of visits due to mental health in the six months after the landslides, from 13,875 to 17,690, reaching its maximum one year after the event totalizing 21,980 visits (Dec 2011). The other health administrative regions of Rio de Janeiro state were used as control group. For secondary outcomes we evaluated the total number of deaths by any reason, and the total number of hospitalizations. The primary outcome was defined as Mental Health Care Demand, and for that we calculated the number of mental health care visits per month, the proportion of visits due to mental health care and the monthly absolute number of mental health care visits per CAPS - "Centro de Atenção Psicossocial" (Psychosocial Care Centre). This study reviewed the consequences of the 2011 disaster in the "Região Serrana", by comparing the demand for public mental health assistance data from time periods before and after the even  METHODS  We performed an ecologic study, analysing the aggregate data from "Região Serrana" during the period two years before and after the disaster, exporting data from the Brazilian open access public health database. Few studies addressed the impacts of this disaster on public health, and we found none addressing the impact on mental health.
These events led to the largest disaster registered in Brazilian recent history.
