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 ...

Insect parasitoids are under selection pressure to optimize their host location strategy in order to maximize fitness. In parasitoid species that develop on host eggs, one of these strategies consists in the exploitation of oviposition-induced plant ...

No Intersexual Differences in Host Size and Species Usage in \u3ci\u3eSpalangia Endius\u3c/i\u3e (Hymenoptera: Pteromalidae) [PDF]
Spalangia endius were collected from fly pupae, primarily house fly and stable fly, from a poultry house in Indiana. Male and female wasps did not differ within and across host species in host size usage.

Egg Parasitoids of Citrus Weevils in Guadeloupe
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 ...

Lack of phenotypic and evolutionary cross-resistance against parasitoids and pathogens in Drosophila melanogaster [PDF]
BackgroundWhen organisms are attacked by multiple natural enemies, the evolution of a resistance mechanism to one natural enemy will be influenced by the degree of cross-resistance to another natural enemy.

Phenotypic plasticity and fitness in egg parasitoids [PDF]
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 ...
