Summary: This study evaluated the effect of phylogenetic (and taxonomic) signals of plants and host species on parasitoid host range. The results indicated the importance of phylogenetic (or taxonomic) signals in dictating parasitoid host specificity. Identifying these signals could be useful for biological control programs.

Summary: This review summarizes the current knowledge on the taxonomy, biodiversity, and ecology of cereal aphid parasitoids in Europe. The study presents approaches to studying aphid-parasitoid-hyperparasitoid food webs and the effects of secondary endosymbionts on parasitoid community composition. It also reviews the impacts of agricultural practices, environmental variation, and landscape complexity on cereal aphid food webs and biological control.

Summary: The study showed that kdr-resistant green peach aphids are more affected by high concentrations of lambda-cyhalothrin compared to susceptible aphids, leading to reduced behaviors, survival, longevity, and oviposition rate of the parasitoids.

Summary: This study investigated the effects of sweet pepper, cucumber, and eggplant as host plants on the survival and fecundity of green peach aphid and the population growth parameters of Aphidius platensis. The results showed that sweet pepper was the most suitable host plant for green peach aphid development and reproduction, and the intrinsic rates of increase for aphids reared on eggplant, sweet pepper, and cucumber were 0.32, 0.33, and -0.071 d(-1), respectively. The intrinsic rate of increase for A. platensis reared on sweet pepper was 0.29 d(-1). These findings suggest that sweet pepper could be a suitable host plant for rearing both M. persicae and A. platensis within a biological control program.

Summary: The study analyzed and compared the patterns of molecular and morphological divergence in European parasitoid wasps of the genus Aphidius Nees, 1818, identifying significant phylogenetic lineages. Despite some low resolution in molecular data, there was still a correlation between morphological variance and molecular evolution in certain well-defined groups.

Summary: Seven commonly used pesticides were tested for their toxicity effects on the parasitoid Aphidius gifuensis, with thiamethoxam and dinotefuran showing the highest toxicity. The study also found that certain pesticides had a greater impact on the survival and parasitism of adults at different time points. Additionally, the egg and larval stages of the parasitoid were more susceptible to pesticides compared to the pupal stage.

Summary: The study found that host deprivation for 19 days did not decrease the effectiveness of H. hebetor. F-1 individuals after PW-20 treatment had higher life table parameters and paralysis rate parameters compared to those without host deprivation. No difference was observed between the two host deprivation treatments, indicating that immediate host deprivation may be just as effective as deprivation after 1 day of host contact.

Summary: Based on original research data from Lithuania, this study documents ten species of aphid parasitoids of the genus Pauesia, with seven newly recorded. Analyses of DNA sequences suggest potential new species, indicating a high level of genetic diversity within these parasitoids. Further research is needed to fully understand the evolutionary relationships and diversity within this group.

Summary: This study aimed to investigate the infestation pattern of GWA in north-western Patagonia, its effect on exudate availability, and its relationship with yellowjacket foraging patterns. The study found that aphid honeydew is produced in relatively high amounts in the region and yellowjackets forage on honeydew significantly more than in nearby areas.

Summary: The study found that different protective bacterial symbionts have varying effects on the interaction between insect hosts and parasitoids, with weak effects on host defense behaviors but strong impacts on resistance against parasitoid development. Despite the significant influence on parasitism resistance, symbiont effects on host defensive behaviors varied greatly among different aphid-symbiont associations. The symbiotic status of aphid individuals did not impact parasitoid attack rate, emergence rate, or life-history traits. These results suggest no trade-offs or positive associations between symbiont-mediated phenotypes in the host-parasitoid interaction.

Summary: Recent advances in insect-microbe interactions have shown that microbial associates can influence the behaviors of their hosts, such as host plant choice in phytophagous insects. However, this study found that the symbiotic status has minor effects on aphid host plant selection, indicating that this trait is primarily determined by the aphid genome. Thus, the evolution of the diet breadth of phytophagous insects may be more influenced by genetic factors rather than microbial symbionts.

Summary: This study examined the combined impact of temperature and plant quality on body size and development time of Eccritotarsus eichhorniae, an herbivorous insect used for biological control against water hyacinth. Results showed that body size decreased with higher temperature and lower plant quality, with smaller individuals having proportionately less lipid content but potentially higher flight ability due to lower wing loading.

Summary: The study revealed that aphid genotypes have differential responses to the alarm pheromone, while the presence of facultative symbionts does not affect these responses. Electrophysiological recordings from the antenna showed significant sensitivity differences between aphid genotypes, but not as a result of symbionts, corresponding to behavioral results.

Summary: The study explores how ectotherm insects, such as parasitoids and their hosts, respond to variable and unpredictable temperature conditions through phenotypic plasticity and bet-hedging. It discusses the implications of fluctuating temperatures on population persistence, host-parasitoid interactions, and potential cascading effects on the food web. The review also proposes a roadmap for designing experiments to assess the adaptive strategies of plasticity and bet-hedging in response to fluctuating temperatures.

Summary: Ecological specialization is common in animals, especially phytophagous insects, resulting from divergent selection on insect populations. Symbionts may influence insect foraging capacities, with potential consequences on dispersal and survival. However, the main influence of secondary symbionts is on the production of winged offspring rather than short-distance exploration and host plant selection.

Summary: This study investigated the response of the aphid parasitoid Aphidius platensis to photoperiod and temperature in five Chilean populations. The results showed that none of the populations expressed diapause, suggesting that the environmental thresholds for diapause induction may not be reached in this species under the studied latitudes. However, there were differences in temperature among sites, and physiological and life-history traits could rapidly adjust through developmental thermal acclimation.

Summary: Generalist parasitoids are widely used as biological control agents due to their ability to parasitize various insect species, but genetic differentiation among populations and alterations in genetic variation within mass-reared populations may lead to reduced efficiency in controlling targeted pest species. The genetic and ecological bases of inefficiency in controlling aphids with the generalist parasitoid Aphidius ervi in strawberry greenhouses were investigated, revealing a genetic differentiation between commercial and wild populations associated with a loss of genetic diversity within mass-reared populations.

Summary: Research indicates that different biotypes of the pea aphid have varying levels of protection from facultative endosymbionts, with interactions between endosymbionts and parasitoid communities. While parasitoid pressure varies seasonally, its influence on endosymbiont dynamics at a seasonal scale is limited.

Summary: The study investigated the plasticity in body coloration of English-grain aphids, demonstrating that their color-change is controlled by light intensity and can be reversed quickly. This adaptive plasticity allows aphids to respond to shifts in environmental conditions and is fully reversible, even in adulthood.
