Interspecific mating of the introduced bumblebee Bombus terrestris and the native Japanese bumblebee Bombus hypocrita sapporoensis results in inviable hybrids
TLDR
Evaluated hybrid production between the introduced B. terrestris and the indigenous B. hypocrita sapporoensis suggested that eggs derived from interspecific matings are inviable due to post-mating isolation mechanisms, which could cause serious population declines of native bumblebee species.

Reproductive differences between Q and B whiteflies, Bemisia tabaci, on three host plants and negative interactions in mixed cohorts
TLDR
Compared the reproductive capacities of these species at different temperatures on three host plants and investigated negative interactions in the mixed cohort of mated females of both species, the reduction in female Q progeny suggests that the interaction between B and Qwhiteflies negatively affects only Q whiteflies, resulting in a lower Q population in the presence of B whiteflies.

Nest materials and some chemical characteristics of nests of a New World swarm-founding polistine wasp, Polybia paulista (Hymenoptera Vespidae)
TLDR
The present result supports the view that amino acid composition of the protein in nests reflects phylogenetical relationships among wasps.

Effects of food availability and age on the reproductive effort of the apple snail, Pomacea canaliculata (Lamarck) (Gastropoda: Ampullariidae)
The effects of food availability and age on the reproductive traits of Pomacea canaliculata were determined in snails fed at three food levels under laboratory conditions (14L:10D; 25°C). In males,…

The effect of a seasonal time constraint on development time, body size, condition, and morph determination in the horned beetle Allomyrina dichotoma L. (Coleoptera: Scarabaeidae)
TLDR
In horned beetles selection favours males that adjust their investment in horn development in relation to cues that predict adult body size, and there is a significant discontinuity in the horn length body size allometry in the Japanese horned beetle, Allomyrina dichotoma.

Sex mosaics in a male dimorphic ant Cardiocondyla kagutsuchi
TLDR
The results suggest that the production of sex mosaics in this species does not pose a substantial cost to colonies and that the underlying causes are therefore not strongly selected against.

Size dependent predatory pressure in the Japanese horned beetle,Allomyrina dichotoma L. (Coleoptera; Scarabaeidae)
TLDR
Morphological comparisons between living marked and prey individuals indicated that the larger horned males suffered higher predatory pressure than the smaller ones, which suggested that the large-horned males suffer not only the injury risk of intrasexual competition but also more predatory risk than the small-hornes.

Queen and worker policing in monogynous and monandrous colonies of a primitively eusocial wasp
TLDR
This work conducted field and laboratory studies to evaluate queen and worker policing in queen–right colonies of the primitively eusocial wasp Polistes chinensis antennalis, revealing that both queen and workers removed both queen– and worker–laid eggs in monogynous and monandrous colonies.

Colour-associated mating success in a polymorphic Ladybird Beetle, Harmonia axyridis
TLDR
The results suggest both body size and colour morph affect the male mating success and males of different body size obtain mating advantage according to the colour morph.

Difference in the time of mating activity between host‐associated populations of the rice stem borer, Chilo suppressalis (Walker)
TLDR
Seasonal and temporal mating activity differences support the idea that males from the wateroat vegetation migrate to the rice field, and body size data showed that the male moths attracted to the pheromone traps at theWateroat vegetation were significantly larger than those at the Rice field, suggesting that the traps atThe two locations mainly attracted moths originating from different host plants.
