Transgenerational phenotypic plasticity of diapause induction and related fitness cost in a commercial strain of the parasitoid Aphidius ervi Haliday
<p>Dataset.</p> <p>Diapause is an adaptation that insects have evolved to synchronize their life cycle with that of seasonal climatic changes and resources availability. However, cues for its induction are not always clear and, in some cases, a maternal effect may be involved. At the population level, just a part of the individuals may exhibit diapause with important consequences in terms of winter survival. Moreover, clear indicators of diapause state are difficult to identify. Diapause induction was thus investigated in the aphid parasitoid species Aphidius ervi Haliday (Hymenoptera: Braconidae) developing in the aphid Sitobion avenae (Hemiptera: Aphididae) at four crossed photothermal regimes (16 °C and 8 °C, 16:8 h L:D and 8:16 h L:D), and during 2 successive generations. We analyzed the reliability of changes in mummy color to assess for the diapausing state compared to dissections, and we measured parasitoid morphological and physiological traits. We observed that the proportion of dark brown mummies increased after one generation under low photothermal regime compared to other regimes. No diapause was recorded at 16 °C, 16:8 h L:D, while we observed 16.2% and 67.5% diapause incidence at 8 °C, 8:16 h L:D, at 1st and 2nd generation, respectively. Diapause induction is thus increased by short day-length conditions and low temperatures as well as by maternal effects. All parasitoid life-history traits (weight, size, fat content, water content, egg-load, and longevity) were affected by the photothermal regime and/or the generation. These results raise new questions on the environmental thresholds needed to induce diapause and on survival and adaptation potential of commercially available parasitoid strains in different environments.</p>
Developmental Temperature Affects Life-History Traits and Heat Tolerance in the Aphid Parasitoid Aphidius colemani
<p>Dataset associated to the paper "Developmental Temperature Affects Life-History Traits and Heat Tolerance in the Aphid Parasitoid<em> Aphidius colemani". </em>In this study, we exposed the aphid parasitoid <em>Aphidius colemani</em> to different temperature regimes (10, 20, or 28 °C) throughout larval development and measured morphological and physiological traits indicator of fitness and heat tolerance in the adult.</p>
Overwintering strategies and life-history traits of different populations of Aphidius platensis along a latitudinal gradient in Chile
<p>The onset of an overwintering strategy to overcome cold temperatures of a species of ectotherms can include<br> remaining active or entering diapause. This in turn will depend on the relative costs of each strategy and therefore, could differ among populations along a latitudinal gradient. Thus, expecting higher levels of diapause in the coldest conditions and a higher incidence of individuals remaining active in the warmest conditions. We assessed the insect responses to photoperiod and temperature, in five Chilean populations of the aphid parasitoid Aphidius platensis. We analysed the variation in winter temperature along the latitudinal gradient and, under controlled conditions, examining the potential effects of three constant conditions of photoperiod/temperature: 8:16LD (Light: Dark, hours) at 10°C, 10:14LD at 14°C, and 16:8LD at 20°C, on diapause levels. Finally, we measured cold tolerance (CTMin), developmental time, fresh body mass and size, fat and water content, and egg load for the emerging parasitoids. Our results showed no clear latitudinal gradient in temperature but differences among sites were clear. None of the five populations of A. platensis expressed diapause at any tested condition, suggesting that the environmental thresholds for diapause induction are perhaps not reached in this species under the studied latitudes. Insects from the coldest point in the gradient (Pinto) showed the lowest CTMin suggesting local adaptation. Moreover, physiological and life-history traits seem to adjust rapidly through developmental thermal acclimation, showing that plasticity is involved in the parasitoid’s responses to the temperature differences found among localities. Consequently, both local adaptation and phenotypic plasticity contribute to this species remaining active during the whole<br> winter, being an effective strategy to diapause in relatively mild and stable thermal environments.</p>

FIGURE 3. Median-joining network of mtCOI haplotypes obtained for 11 Aphidius urticae specimens. White circles represent group 1—haplotypes H4 and H6 from Microlophium carnosum; grey circles represent group 2—H1 from Macrosiphum funestum and H5 from Aulacorthum vaccinii; and black circles represent group 3—H3 and H2 from Amphorophora rubi. Circle size reflects the number of individuals with that haplotype (not to scale). Red circles are median vectors. Due to the large genetic differences between the groups, nucleotide substitutions were presented numerically as 11 and 48 mutational steps instead of presenting each step as one dot.
