Average values ± standard errors are shown. Before and after refer to weekly measurements made either before or after autodissemination station deployment (see text for more details). Letters indicate statistically significant difference within each year and measured response. For pupal mortality, laboratory reference samples, containers deployed in the field (Field), and naturally occurring containers (Container, 2015–2016 only) in both the reference (reference) and autodissemination treatment blocks (treatment) are shown. nd designates no data were collected.
