Thermal resilience may shape population abundance of two sympatric congeneric Cotesia species (Hymenoptera: Braconidae)

Thermal resilience may shape population abundance of two sympatric congeneric Cotesia species (Hymenoptera: Braconidae)

Basal and plasticity of thermal tolerance determine abundance, biogeographical patterns and activity of insects over spatial and temporal scales. For coexisting stemborer parasitoids, offering synergistic impact for biological control, mismatches in thermal tolerance may influence their ultimate impact in biocontrol programs under climate variability. Using laboratory-reared congeneric parasito...

The systematics and biology of Cotesia nonagriae (Olliff) stat. rev. (Hymenoptera: Braconidae: Microgastrinae), a newly recognized member of the Cotesia flavipes species complex

The Australian species Cotesia nonagriae Olliff stat. rev. (Hymenoptera: Braconidae) is redescribed and formally removed from synonymy with C. flavipes based on molecular, morphological and biological differences. The taxonomic history and phylogenetic relationships of C. nonagriae with other members of the C. flavipes complex are presented and underscore the importance of molecular-based ident...

Genetic Divergence Among Host-Specific Cryptic Species in Cotesia melitaearum Aggregate (Hymenoptera: Braconidae), Parasitoids of Checkerspot Butterflies

We used mitochondrial DNA sequence data and 12 microsatellite loci to examine the genetic structure of Cotesia melitaearum (Wilkinson) (Hymenoptera: Braconidae), a parasitoid wasp reared from two common butterßy species, Melitaea cinxia (L.) (Lepidoptera: Nymphalidae) and Euphydryas aurinia (Rottemburg) (Lepidoptera: Nymphalidae), acrossmany localities in Europe and Asia, aswell as from fourmor...

Predicting population dynamics of the parasitoid Cotesia marginiventris (Hymenoptera: Braconidae) resulting from novel interactions of temperature and selenium

Differences in growth trajectory and strategy of two sympatric congeneric species in an Indonesian floodplain forest.

Whole-plant development trajectories and sapling leaf displays were compared for two sympatric congeneric species, Pterospermum diversifolium and P. javanicum, in a tropical floodplain forest in East Kalimantan, Indonesia. We assessed their growth strategies and developed hypotheses for their coexistence within the community. Pterospermum diversifolium retains a monoaxial growth habit that prom...
