Prey life-history influences the evolution of egg mass and indirectly reproductive investment in a group of free-living insect predators. [PDF]

open access: yesEcol Evol, 2022
In insect predator, prey influences the evolution of life‐history traits. After controlling for phylogenetic relatedness, we show that ladybirds specialized on aphids lay bigger eggs than those that specialized on coccids. However, the two types of ladybirds invest equally in reproduction.

Potential of variegated lady beetle Hippodamia variegata in management of invasive tomato potato psyllid Bactericera cockerelli. [PDF]

open access: yesPest Manag Sci, 2023
Resident predator Hippodamia variegata successfully reproduced and established populations when feeding on invasive pest, Bactericera cockerelli. Therefore, H. variegata could be a potential biological control agent for B. cockerelli. This is the first report of a generalist predator feeding and developing on the invasive B.
