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 ...

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 ...

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 ...
