Larval density in the invasive Drosophila suzukii: Immediate and delayed effects on life‐history traits

ABSTRACT: Abstract The effects of density are key in determining population dynamics, since they can positively or negatively affect the fitness of individuals. These effects have great relevance for polyphagous insects for which immature stages develop within a single site of finite feeding resources. Drosophila suzukii is a crop pest that induces severe economic losses for agricultural production; however, little is known about the effects of density on its life‐history traits. In the present study, we (i) investigated the egg distribution resulting from females' egg‐laying strategy and (ii) tested the immediate (on immatures) and delayed (on adults) effects of larval density on emergence rate, development time, potential fecundity, and adult size. The density used varied in a range between 1 and
