The spiral plant-parasitic nematode genus Rotylenchus contains a cosmopolitan group of nematodes that is predominantly found in temperate regions of the world. In this genus are included a number of species of significant economic importance in agriculture. They parasitize a wide-range of hosts, including vegetables, ornamentals, and fruit and forest trees.
The book comprises seven sections and presents summarised and specialised information on various aspects of the spiral nematodes belonging to the genus Rotylenchus. Sections 1 and 2 describe the importance of Rotylenchus species in agricultural crops, their distribution and numerous aspects of their biology, feeding habits, pathogenicity to vegetables, fruit and forest trees, and ecology. Section 3 presents different management strategies for the most important and pathogenic species of Rotylenchus, including chemical control, crop rotation, and biological control by means of nematophagous fungi, entomopathogenic nematodes, the hyperparasitic bacteria Pasteuria penetrans, and nematicidal plants. Sections 4 and 5 describes the most important morphological characters used in characterising and diagnosing species, as well as a broad discussion on the taxonomy and systematics in Rotylenchus and related genera, including a list of nominal species. These sections also include morphometric and cluster analyses in order to separate groups of species in order to facilitate identification. Section 6 provides a complete description and measurements of all populations characterised for each species, as well as their world distribution. Finally, Section 7 includes comprehensive tabular and dichotomous keys for species identification.
Root-lesion nematodes of the genus Pratylenchus are recognised worldwide as one of the major constraints of crops of primary economic importance. Pratylenchus spp. comprises around 70 nominal species of worldwide distribution which parasitize a wide variety of plants. The book consists of ten chapters and presents summarised and specialised information concerning the importance of the Pratylenchus species in: agricultural crops, and their world distribution (chapter 1); taxonomy, systematic, general morphology and diagnostic traits of Pratylenchus spp. including new technologies based on biochemical and molecular analyses (chapters 2-6); biology, epidemiology, ecology, host-parasite relationships, and pathogenicity (chapters 7-9). Finally, it illustrates different management strategies for Pratylenchus species, including, crop rotation, host-plant resistance, chemical control, soil solarisation, and biological control (chapter 10). 

The role of gender equality considerations, including the gender balance of peacekeeping operations, has been underplayed as a potential solution to the un’s recurrent problems with sexual exploitation and abuse by blue helmets. This article explores 3 elements related to gender equality that have been neglected in responding to this issue: the presence of women in peacekeeping operations, the voice and opinion of women’s organizations, and the assistance to victims of such violations. The connection between women’s leadership and participation, on the one hand, and better outcomes for women and girls on the other, has been evident in many related policy areas, and should be applied more forcefully in addressing sexual exploitation and abuse by un peacekeepers.
