Extended time to maturity in <i>Anopheles coluzzii</i> : Implications of late egg hatch for vector control and transgene fitness Open
Maintaining fitness is an important consideration when mosquitoes are mass‐reared for the deployment of genetic interventions that are designed to suppress populations because released mosquitoes need to compete with wild‐type mosquitoes. …

Using radio frequency identification technology to track the movement of slugs within domestic garden habitats Open
Slugs (Gastropoda: Stylommatophora) are common domestic garden inhabitants in the United Kingdom (UK) but few studies have explored the spatial behaviour of slugs within these habitats, largely due to limitations in available mark-recaptur…

The influence of genetic variation on pre‐oviposition processes for host‐parasitoid co‐evolution Open
Despite the importance of parasitoid wasps as biological control agents and the vast literature available on different aspects of their natural history and ecology, it is only recently that an interest in integrating genetics into aphid‐pa…

The clip cage conundrum: Assessing the interplay of confinement method and aphid genotype in fitness studies Open
Behavior and fitness are important ecological traits frequently measured in insect bioassays. A common method to measure them in soft‐bodied herbivorous insects involves confining individuals to plant leaves using clip cages. Although stud…
