Life-history strategies in parasitoid wasps: a comparative analysis of ‘ovigeny’
It is concluded that 'ovigeny' is a concept applicable to insects generally, and the hypothesis that it is associated with a tendency towards a low ovigeny index is supported. Expand
Resource acquisition, allocation, and utilization in parasitoid reproductive strategies.
This work relates parasitoid reproduction both to inter- and intraspecific patterns of nutrient allocation, utilization, and acquisition, and to key aspects of host ecology, specifically abundance and dispersion pattern. Expand
Factors affecting the evolution of development strategies in parasitoid wasps: the importance of functional constraints and incorporating complexity
- J. Harvey
- 1 October 2005
A range of ecophysiological constraints that affect host quality and development strategies in parasitoids are discussed, including integration of a suite of direct and indirect mechanisms, including biological processes occurring in different ecological realms, such as above‐ground and below‐ground interactions. Expand
Root herbivore effects on above-ground herbivore, parasitoid and hyperparasitoid performance via changes in plant quality
It is shown, for the first time, that root herbivory via changes in plant quality can reduce the performance of an above-ground multitrophic level food chain. Expand
Response of native insect communities to invasive plants.
The impact of invasive plants on the population dynamics of resident insect species has been rarely examined, but invasive plants can influence the spatial and temporal dynamics of native insect (meta)populations and communities, ultimately leading to changes at the landscape level. Expand
Intrinsic inter- and intraspecific competition in parasitoid wasps.
The evolution of gregarious development in parasitoids reflects differences in various developmental and behavioral traits, as these influence antagonistic encounters among immature parasitoid wasps. Expand
Dynamic effects of parasitism by an endoparasitoid wasp on the development of two host species: implications for host quality and parasitoid fitness
- J. Harvey
- 1 August 2000
1. The study reported here examined growth and developmental interactions between the gregarious larval koinobiont endoparasitoid Cotesia glomerata (Hymenoptera: Braconidae) and two of its hosts that… Expand
FLEXIBLE LARVAL GROWTH ALLOWS USE OF A RANGE OF HOST SIZES BY A PARASITOID WASP
Compared growth trajectories of the koinobiont ichneumonid endoparasitoid Venturia canescens developing in four larval instars of one of its hosts, the moth Plodia interpunctella, show that for Venturia, host quality is not a direct function of host size at parasitism. Expand
Linking above- and belowground multitrophic interactions of plants, herbivores, pathogens, and their antagonists
Combining both above- and belowground compartments in studies of multitrophic interactions throughout the life cycle of plants will improve the understanding of ecology and evolution in the real world. Expand
Soil community composition drives aboveground plant-herbivore-parasitoid interactions
The composition of the soil community matters for aboveground multitrophic interactions for aphids and parasitoids, and for nematode and microorganism inoculations of model grassland ecosystems. Expand
