The evolution of gregariousness in parasitoid wasps [PDF]
, 1998 Data are assembled on the clutch-size strategies adopted by extant species of parasitoid wasp. These data are used to reconstruct the history of clutch-size evolution in the group using a series of plausible evolutionary assumptions.

Nest enlargement in leaf-cutting ants: relocated brood and fungus trigger the excavation of new chambers. [PDF]
PLoS ONE, 2014 During colony growth, leaf-cutting ants enlarge their nests by excavating tunnels and chambers housing their fungus gardens and brood. Workers are expected to excavate new nest chambers at locations across the soil profile that offer suitable ...

The threat of pesticide and disease co-exposure to managed and wild bee larvae
International Journal for Parasitology: Parasites and Wildlife, 2022 Brood diseases and pesticides can reduce the survival of bee larvae, reduce bee populations, and negatively influence ecosystem biodiversity. However, major gaps persist in our knowledge regarding the routes and implications of co-exposure to these ...

Towards integrated control of varroa: effect of variation in hygienic behaviour among honey bee colonies on mite population increase and deformed wing virus incidence [PDF]
, 2014 Hygienic behaviour in the honey bee, Apis mellifera, is the uncapping and removal of dead, diseased or infected brood from sealed cells by worker bees. We determined the effect of hygienic behaviour on varroa population growth and incidence of deformed ...

Integrated Environmental Assessment and Management, 2014 This study aimed to develop an approach to evaluate potential effects of plant protection products on honeybee brood with colonies at realistic worst‐case exposure rates. The approach comprised 2 stages. In the first stage, honeybee colonies were exposed
