Intra-population genetic variation in the temporal pattern of egg maturation in a parasitoid wasp. [PDF]

PLoS ONE, 2012
Parasitoid wasps are taxonomically and biologically extremely diverse. A conceptual framework has recently been developed for understanding life-history evolution and diversification in these animals, and it has confirmed that each of two linked life ...

Response of parasitoid egg load to host dynamics and implications for egg load evolution [PDF]

Journal of Evolutionary Biology, 2017
AbstractA theoretical debate about whether parasitoids should be time or egg limited now recognizes both as feasible, and interest has turned to determining the circumstances under which each might arise in the field, and their implications for parasitoid behaviour and evolution.

Maize landraces recruit egg and larval parasitoids in response to egg deposition by a herbivore.

Ecology letters, 2012
Natural enemies respond to herbivore-induced plant volatiles (HIPVs), but an often overlooked aspect is that there may be genotypic variation in these 'indirect' plant defence traits within plant species. We found that egg deposition by stemborer moths (Chilo partellus) on maize landrace varieties caused emission of HIPVs that attract parasitic wasps ...

Impact of Temperature on the Immune Interaction between a Parasitoid Wasp and Drosophila Host Species

Insects, 2021
Temperature is particularly important for ectotherms, including endoparasitoid wasps that develop inside another ectotherm host. In this study, we tested the impact of three temperatures (20 °C, 25 °C and 30 °C) on the host–parasitoid immune interaction ...

Anti-aphrodisiac compounds of male butterflies increase the risk of egg parasitoid attack by inducing plant synomone production [PDF]

, 2009
During mating in many butterfly species, males transfer spermatophores that contain anti-aphrodisiacs to females that repel conspecific males. For example, males of the large cabbage white, Pieris brassicae (Lepidoptera: Pieridae), transfer the anti ...

Egg Parasitoids of Citrus Weevils in Guadeloupe

Florida Entomologist, 2008
To determine parasitism and mortality factors affecting citrus weevils in Guadeloupe an explor atory trip to the island was taken in the summer of 2006. Guadeloupe was surveyed for egg parasi toids and other natural enemies with the intent of augmenting the parasitoid species that have al ready been imported and released to control the citrus root ...

Native and Non-Native Egg Parasitoids Associated with Brown Marmorated Stink Bug (Halyomorpha halys [Stål, 1855]; Hemiptera: Pentatomidae) in Western Slovenia

Insects, 2021
Halyomorpha halys (Hemiptera: Pentatomidae), native to East Asia, has become a globally invasive pest, as a serious threat to agricultural production and a notorious nuisance pest in urban areas.

The Significance of Background Odour for an Egg Parasitoid to Detect Plants with Host Eggs [PDF]

Chemical Senses, 2005
Scots pine has been shown to produce a volatile bouquet that attracts egg parasitoids in response to oviposition of the herbivorous sawfly Diprion pini. Previous analyses of headspace volatiles of oviposition-induced pine twigs revealed only quantitative changes; in particular, the sesquiterpene (E)-beta-farnesene was emitted in significantly higher ...

Characteristics of the meconia of European egg parasitoids of Halyomorpha halys [PDF]

Journal of Hymenoptera Research, 2020
Halyomorpha halys is a severe invasive Asian pest worldwide and classical biological control is foreseen as the most promising control method. Egg parasitoids appear to be the most important natural enemies of this pest, especially the Asian hymenopteran

Phenotypic plasticity and fitness in egg parasitoids [PDF]

Neotropical Entomology, 2010
Several proxies can be used to estimate the fitness of egg parasitoids: size, longevity, fecundity, mating ability and vagility. All these proxies are positively correlated with the lifetime fitness gain of an individual. However, the phenotypic plasticity, which is the ability of a genotype to produce distinct phenotypes depending on environmental ...
