Factors influencing the evolution of clutch size in a gregarious insect parasitoid
(WILEY-BLACKWELL, 2000)
1. In this study we examined the clutch size of Hyssopus pallidus (Askew) (Hymenoptera, Eulophidae), a gregarious ectoparasitoid of codling moth (Lepidoptera, Tortricidae) larvae that is characterized by a host handling ...
Phenotypic plasticity in clutch size regulation among populations of a potential invasive fruit fly from environments that vary in host heterogeneity and isolation
(Cambridge University Press, 2018-05)
Phenotypic plasticity is thought to evolve in response to environmental unpredictability and can shield genotypes from selection. However, selection can also act on plastic traits. Egg-laying behaviour, including clutch ...
Host specific reproductive benefits, host selection behavior and host use pattern of the pinnotherid crab Calyptraeotheres garthi
(Elsevier Science, 2012-11)
In organisms using a wide variety of refuges, both the cost and benefits to the users might be refuge-specific. Under these circumstances, users using mechanisms (e.g., behavioral preference) that allow them to find and ...
Sex-dependent infection causes nonadditive effects on kissing bug fecundity
(Wiley, 2017-05)
The influence of parasites on host reproduction has been widely studied in natural and experimental conditions. Most studies, however, have evaluated the parasite impact on female hosts only, neglecting the contribution ...
Parasitic assemblages on leafminers: a comparison of structure and function among host Orders
(Taylor & Francis Ltd, 2011-04)
In this study we ask whether parasitic complexes of leafminers display differences associated to host order, by comparing species number, taxonomic composition, parasitism rates and host ranges in parasitoid assemblages ...
Local Host Adaptation and Use of a Novel Host in the Seed Beetle Megacerus eulophus
(Public Library of Science, 2013)
Spatial variation in host plant availability may lead to specialization in host use and local host adaptation in herbivorous insects, which may involve a cost in performance on other hosts. We studied two geographically ...
Helminth community structure of Scinax nasicus (Anura: Hylidae) from a South American subtropical area
(Inter-Research, 2010-12)
The main goal of this study was to evaluate the relative influence of season, year of study, host body size, and host sex on abundance of helminth species parasitic in the frog Scinax nasicus. A total of 273 frogs was ...
Host ontogeny and the temporal decay of similarity in parasite communities of marine fish
(Elsevier, 2010-07)
Geographical distances between host populations are key determinants of how many parasite species they share. In principle, decay in similarity should also occur with increasing distance along any other dimension that ...
Size and flight ability of Telenomus remus parasitoids reared on eggs of the factitious host Corcyra cephalonica
(Soc Brasileira Entomologia, 2016-04-01)
In two independent bioassays, size and flight ability of parasitoids reared on eggs of Corcyra cephalonica for 19 generations and parasitoids reared on a natural host (Spodoptera frugiperda eggs) for 250 generations were ...
