Intergenerations effects of starvation on Athalia
<p>Intergenerational effects, also known as parental effects in which the offspring phenotype is influenced by the parental phenotype, can occur in response to factors that occur not only in early but also in late parental life. However, little is known about how these parental life stage-specific environments interact with each other and with the offspring environment to influence offspring phenotypes, particularly in organisms that realize distinct niches across ontogeny. We examined the effects of parental larval starvation and adult reproductive environment on offspring traits under matching or mismatching offspring larval starvation conditions using the holometabolous, haplodiploid insect <i>Athalia rosae</i> (turnip sawfly). We show that parental larval starvation had trait-dependent intergenerational effects on both life-history and consumption traits of offspring larvae, partly in interaction with offspring conditions, while there was no significant effect of parental adult reproductive environment. In addition, while offspring larval starvation led to numerous gene- and pathway-level expression differences, parental larval starvation impacted far fewer genes and only the ribosomal pathway. Our findings reveal that parental starvation evokes complex intergenerational effects on offspring life-history traits, consumption patterns as well as gene expression, although the effects are less pronounced than those of offspring starvation.</p>

Effects of functional depletion of doublesex on male develop-ment in the sawfly, Athalia rosae
<p><strong>Movie S3. </strong>Copulation behavior observed between a wild-type male and a diploid male obtained via complete RNAi. A single wild-type naïve male was introduced into a vial with a diploid male obtained via complete RNAi. The wild-type male successfully copulated with the <em>Ardsx</em> knockdown diploid male obtained by complete RNAi. Video recording started immediately after introducing the naïve wild-type male.</p>
Effects of functional depletion of doublesex on male develop-ment in the sawfly, Athalia rosae
<p><strong>Movie S2. </strong>Mating behavior displayed by diploid males in whom <em>Ardsx</em> expression was knocked down over an entire lifespan. Two wild-type virgin females were introduced in a vial with two diploid males obtained via complete RNAi. One of the<em> Ardsx</em> knockdown males vigorously displayed mating behavior but failed to copulate with the virgin female due to the lack of male external genitalia. Video recording started immediately after introducing the virgin wild-type female.</p>
