Egg load evolution in parasitoids

The American Naturalist, 2000
Parasitic wasps lay their eggs in or on other insects. Allocation of resources to reproduction (eggs) and survival (life span) should maximize reproductive success, but stochasticity in the number of hosts encountered precludes an exact match of ...

Host Searching by Egg Parasitoids: Exploitation of Host Chemical Cues [PDF]

, 2010
Insect parasitoids are considered “keystone species” in many ecosystems in terms of biodiversity, ecological impact and economic importance (Vinson 1985, LaSalle and Gauld 1993, Hawkins et al. 1999).

Assemblage of the Egg Parasitoids of the Invasive Stink Bug Halyomorpha halys: Insights on Plant Host Associations [PDF]

Insects, 2020
Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is an invasive alien species and a key agricultural pest. Its native parasitoids (Trissolcus japonicus Ashmead and Tr. mitsukurii Ashmead) have been registered in several countries where H. halys brought

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.

Comparative study on the egg parasitoids of Erthesina fullo (Thunberg, 1783) (Hemiptera, Pentatomidae) in its native and invaded ranges [PDF]

NeoBiota
Erthesina fullo (Thunberg, 1783) (Hemiptera, Pentatomidae) is an emerging invasive pest outside its native Asian range, yet little is known about its egg parasitoids. Egg parasitoid assemblages were surveyed from field-collected egg masses of E. fullo in

Egg Parasitoids Survey of Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) in Maize and Sorghum in Central Mexico [PDF]

Insects, 2020
Spodoptera frugiperda (Smith) is the main maize pest in America and was recently detected as an invasive pest in some countries in Asia and Africa. Among its natural enemies presented in Mexico, Trichogramma pretiosum Riley is the only egg parasitoid ...

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

Ecology letters, 2011
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.
