TY - T1 - The more the merrier : Conspecific density improves performance of gregarious larvae and reduces susceptibility to a pupal parasitoid SN - / UR - http://hdl.handle.net/10138/231478 T3 - A1 - Rosa, Elena; van Nouhuys, Saskya; Saastamoinen, Marjo A2 - PB - Y1 - 2017 LA - eng AB - Aggregation can confer advantages in animal foraging, defense, and thermoregulation. There is a tight connection between the evolution of insect sociality and a highly effective immune system, presumably to inhibit rapid disease spread in a crowded environment. This connection is less evident for animals that spend only part of their life cycle in a social environment, such as noneusocial gregarious insects. Our aim was to elucidate the effects of group living by the gregarious larvae of the Gla...
