Several species of Orius Wolff are used in biological control of thrips in protected cultivations in temperate regions, but some of them show reproductive diapause, compromising the efficiency of these agents of biological control. There are no reports on the biology of the neotropical species Orius thyestes Herring under different environmental conditions. The purpose of this work was to inves...

Ecological linkages between species diversity in communities and genetic diversity in populations have potential to influence the assembly of communities in habitats recovering from human disturbance, but few studies have attempted to synthesize relationships between these levels of biological organization, especially for locally adapted species. No such studies have been done in freshwater eco...

Morphological characteristics of the acanthocephalan Polymorphus minutus (Goeze, 1782), which was collected from duck Anas platyrhynchos Linnaeus in Czech Republic, are described. The mitochondrial (mt) genome P. sequenced, with a total length 14,149 bp, comprising 36 genes including 12 protein coding (PCGs), 22 transfer RNA (tRNA) and two ribosomal (rrnL rrnS). This is similar to mt genomes ot...

Trophically-transmitted parasites often change the phenotype of their intermediate hosts in ways that increase their vulnerability to definitive hosts, hence favouring transmission. As a "collateral damage", manipulated hosts can also become easy prey for non-host predators that are dead ends for the parasite, and which are supposed to play no role in transmission strategies. Interestingly, inf...

Larval helminths often share individual intermediate hosts with other larval worms of the same or different species. In the case of immature acanthocephalans capable of altering the phenotype of their intermediate hosts, the benefits or costs of host sharing can be evaluated in terms of increased or decreased probability of transmission to a suitable definitive host. Competitive interactions am...
