Relationship between larval mortality rate and first instar larval density. A: When batches of first instar larvae of equal age are placed in breeding sites, the daily mortality rate increases at higher larval densities. The data can be described by a linear (solid) or logistic (dashed) function. B: Placing batches of first instar larvae into breeding sites at staggered times results in a larval population with a mixed age structure. The data are well described by a linear (solid) or a quadratic (dashed) curve. See the Supplementary Information for further details on fitting. Error bars represent 95% confidence intervals for the data. Data are from Njunwa (1993) [12].
