Abstract: 1. Intrinsic competition was compared in three species of braconid wasps, the solitary Meteorus pulchricornis Wesmael, and the gregarious Cotesia kariyai (Watanabe) and Cotesia ruficrus Haliday in caterpillars of their common host, the armyworm Mythimna separata Walker. Competition was determined in pairwise contests consisting of simultaneous and subsequent parasitisms at various time intervals between the first and second attacks (<1, 24, 48, 72, and 96 h).2. The experiment revealed that the solitary M. pulc… Show more

“…For competing hyperparasitoid larvae, a faster development rate results in a more rapid utilisation of host resources and earlier pupation. Although evidence indicates that solitary species may be superior competitors in primary parasitoids (see, for example, Laing & Corrigan, 1987;Magdaraog et al, 2012;Poelman et al, 2014), our results show that a gregarious hyperparasitoid outcompeted its solitary rival. We have found that, when developing in fully grown larvae of C. rubecula, B. galactopus attain their highest growth rate within 3-5 days of oviposition and fully consume their host within only 6 days of oviposition (Zhu & Lammers, unpublished data).…”

“…As host resources are limited, there is little capacity for resource sharing among the progeny of different parasitoid species. For gregarious parasitoids that lay multiple eggs per host, scramble competition is the norm in which even larvae of two species may successfully develop inside the same host (Dorn & Beckage, 2007;Magdaraog et al, 2012). Adult parasitoids compete extrinsically when searching for and exploiting hosts, whereas their larvae compete intrinsically when multiple individuals develop in the same host (Force, 1974;De Moraes et al, 1999;Cusumano et al, 2012;Harvey et al, 2013).…”

“…In this instance, young parasitoid larvae are either not aggressive or they are largely immobile and tolerate the presence of competing larvae (especially conspecifics) until later in development. In some instances, two species of gregarious endoparasitoids have even been shown to develop successfully in the same host to adult eclosion (Dorn & Beckage, ; Magdaraog et al ., ). The outcome of intrinsic competition among parasitoids is both trait‐ and context‐dependent (Harvey et al ., ).…”

“…Based on the presence of characteristics such as biting mandibles and motility, it has been argued that solitary endoparasitoids, by virtue of their monopoly of resources, should out‐compete gregarious endoparasitoids. In laboratory experiments studying intrinsic competition, this has indeed proven to be the general rule (Laing & Corrigan, ; Pexton & Mayhew, , ; Traynor & Mayhew, ; Harvey et al ., , ; Magdaraog et al ., , ). However, in nature many herbivores are attacked by a number of solitary and gregarious endoparasitoids (Hawkins, ; Elzinga et al ., ).…”
