Notes on three braconid wasps (Hymenoptera: Braconidae, Doryctinae) parasitizing oak long-horned beetle, Massicus raddei (Coleoptera: Cerambycidae), a severe pest of Quercus spp. in China, together
Three species of Doryctinae (Hymenoptera: Braconidae) parasitize larvae of oak longhorn beetle Massicus raddei Blessig (Coleoptera: Cerambycidae), a serious wood borer pest in North China.
Revision of parasitoids of Massicus raddei (Blessig Solsky) (Coleoptera, Cerambycidae) in China, with one new species and genus.
TLDR
Fifteen parasitoids of Massicus raddei (Blessig Solsky) (Coleoptera, Cerambycidae) are revised and a new braconid wasp is described, and Cyanopterus tricolor (Ivanov) and Eubazus (E.) pallipes are new records for the Chinese fauna.
Cerchysiella mesosae Yang sp. nov. (Hymenoptera: Encyrtidae), a parasitoid of Mesosa myops (Dalman) (Coleoptera: Cerambycidae) larvae in China.
TLDR
A new species of gregarious koinobiont endoparasitoid in mature larvae of Mesosa myops (Dalman), a wood boring pest of many broad-leaved tree species in China, may have potential as a biological control agent for suppression of the pest.
Relationships between Body Size and Parasitic Fitness and Offspring Performance of Sclerodermus pupariae Yang et Yao (Hymenoptera: Bethylidae)
TLDR
The findings suggest that the parasitic fitness and offspring performance are affected by maternal size, and there is need to choose reasonable body size of female wasps, to optimally utilize mass rearing and to control target pests with the lowest mortality cost.
The developmental strategies and related profitability of an idiobiont ectoparasitoid Sclerodermus pupariae vary with host size
TLDR
Assessment of host profitability revealed that medium‐sized hosts presented the best fitness return for the parasitoids, suggesting that this bethylid parasitoid can achieve a compromise in optimisation of the two most important fitness functions when encountering an abundance of different-sized hosts.
Biomass evaluation of concealed insect pests at parasitism based on allometric scaling laws
TLDR
Findings indicated that host biomass could be easily calculated if any one size variable could be measured at the time of parasitism, and allometric methods provide a precise means of evaluating time-specific biomass of concealed wood borers.
Redescriptions of two parasitoids, Metapelma beijingense Yang (Hymenoptera, Eupelmidae) and Spathius ochus Nixon (Hymenoptera, Braconidae), parasitizing Coraebus cavifrons Descarpentries & Villiers
TLDR
Two parasitoids, Metapelma beijingense Yang and Spathius ochus Nixon, are redescribed and illustrated and a revised key to Oriental and Palaearctic species of MetAPelma Westwood and a key to the species of the Spathii labdacus-group are provided.
