Many parasitoid species are subjected to strong selective pressures from their host, and their adaptive response may result in the formation of genetically differentiated populations, called host races. When environmental factors and reproduction traits prevent gene flow, host races become distinct species. Such a process has recently been documented within the Cotesia flavipes species complex,...

To develop efficient and safe biological control, we need to reliably identify natural enemy species, determine their host range, and understand the mechanisms that drive host range evolution. We investigated these points in Cotesia sesamiae, an African parasitic wasp of cereal stem borers. Phylogenetic analyses of 74 individual wasps, based on six mitochondrial and nuclear genes, revealed thre...

Data and chance are two related topics that deal with uncertainty, and statistics and probability are the mathematical ways of dealing with these two ideas, respectively (Moore, 1990). Unfortunately, existing literature reveals an artificial separation between probability and data analysis in both research and instruction, which some researchers (Shaughnessy, 2003; Steinbring, 1991) have alread...

Plants attacked by herbivorous insects emit volatile compounds that attract predators or parasitoids of the herbivores. Plant fitness increases when these herbivorous insects are parasitized by solitary parasitoids, but whether gregarious koinobiont parasitoids also confer a benefit to plant fitness has been disputed. We investigated the relationship between parasitoid load of the gregarious Co...

this paper reports the occurrence of the hymenoterous parasitoid of the diamondback moth larvae in iran. one species of braconidae, cotesia plutellae (kurdjumov), was collected from larvae of plutella xylostella (l.) (lep.: plutellidae). this parasitoid, which belongs to the subfamily microgastrinae, is newly recorded from iran.

This study determined the first complete mitochondrial genome of a demoiselle, Vestalis melania (Odonata, Zygoptera, Calopterygidae) using long-range PCR and a primer walking approach. This mitogenome is 16,685 bp long and contains the entire set of 37 genes and an A + T-rich control region typically found in insects. Presently, this mitogenome is the largest mitogenome of all available odonate...

Antagonistic relationships between parasitoids and their insect hosts involve multiple traits and are shaped by their ecological and evolutionary context. The parasitoid wasp Cotesia melitaearum and its host butterfly Melitaea cinxia occur in several locations around the Baltic sea, with differences in landscape structure, population sizes and the histories of the populations. We compared the v...
