Characterization of microbial communities in pest colonized books by molecular biology tools
2011
This work presents the identification of bacteria and fungi colonies in insect infesting books, by cultural-independent methodologies based on molecular biology techniques. Microbial genomic DNA extraction,<em> in vitro</em> amplification of specific target sequences by polymerase chain reactions (PCR), sequencing and sequence analysis were performed. These procedures minimized the samples amount, optimized the diagnostic studies on bacteria and fungi colonization and allowed the identification of many species also in complex microbial consortia. The molecular techniques for sure accomplish and integrate the microbiological standard methods (<em>in vitro</em>&nbs…
Drumming signals within the family Taeniopterygidae (Plecoptera)
2014
Drumming signals of the 11 species of Palaearctic Taeniopterygidae are described for the first time based on the study of populations from nine different European countries from Spain to Russia. In this way, a contribution is made to our knowledge of the constancy respectively the divergence of signals typical for the species distributed over a very wide area. Communication patterns of the family under varying temperatures were analysed. The dependence on temperature indicates that the adults of this family are cold stenothermic insects. Within the genus Brachyptera (Newport, 1851), the call signal of males is significantly different from their response signal (duration and drumming frequen…
A Revision of the Nearctic Species of Hecamedoides Hendel (Diptera: Ephydridae)
2008
Abstract Species of the shore-fly genus Hecamedoides Hendel from the Nearctic Region are revised, including description of H. lattini, new species (Virginia. Stafford: Falmouth (38°19.2′N, 77°28.1′W; Rappahannock River; 9 m). To provide context and also to facilitate identification, diagnoses are provided for the tribe Discocerinini and genus in addition to a key to the genera and species, H. lattini and H. unispinosus, occurring in the New World. Diagnostic characters, especially of the male terminalia, are illustrated, and distribution maps are also provided.
Intraspecific Variation of Host Plant and Locality Influence the Lepidopteran-Parasitoid System of <I>Brassica oleracea</I> Crops
2013
ABSTRACT The aim of the study was to investigate the attractiveness to herbivores and parasitoids of two cultivars of Brassica oleracea L., namely, B. oleracea variety acephala (kale) and B. oleracea variety capitata (cabbage), that exhibit differences of morphological and biochemical traits. To this end, field samplings were replicated at seven localities in Galicia (northwestern Spain). Three specialist and three generalist lepidopteran species were sampled. In total, 7,050 parasitoids were obtained, belonging to 18 genera and 22 species. The results showed that 1) parasitism rate and parasitoid species richness changed with locality and was higher in cabbage, although this crop had lower…
Bacteria, fungi and arthropod pests collected on modern human mummies
2011
A survey of opportunistic biocenosis (macro and micro organisms) associated with a rest of human mummy samples was carried out to characterise the biocenosis and to detect the potential of biodeteriogens. The rests of the human modern mummies come from a hypogeic site. Since mummies are relevant from a historic-artistic-scientific point of view, an aspect of this study was the identification and characterization of the biological systems related with biodeterioration of organic matter. In a first step, different sampling methods, according to the taxa, were applied. Technological procedures were combined in order to have an interdisciplinary approach to the conservation actions for testing …
Additions to the Indian oribatid mite fauna, with description of a new species of the genus <em>Niphocepheus</em> (Acari, Oribatida)
2014
An annotated checklist of oribatid mite taxa from three sites of India is presented. It includes 71 species/ subspecies, 55 genera and 35 families. Twenty nine species/subspecies are recorded for the first time in India; five species/subspecies—Trhypochthonius tectorum stercus, Hermanniella aliverdievae, Sphodrocepheus tridactylus, Caenosamerus spatiosus, Dolicheremaeu distinctus—are recorded for the first time in the Oriental region. Niphocepheus neotrichus sp. nov. (Niphocepheidae) is described; it differs from other known species of Niphocepheus by the presence of epimeral neotrichy and three pairs of anal setae.
Host kairomone learning and foraging success in an egg parasitoid: a simulation model
2009
Trissolcus basalis (Wollaston) (Hymenoptera: Scelionidae) is an egg parasitoid that recognises chemical residues left by its host the green stink bug Nezara viridula (L.) (Heteroptera: Pentatomidae) as kairomone signals, enabling it to find egg masses in which to lay eggs. 2. Kairomones are usually present as patches deposited by N. viridula females, and recent results (Peri et al. , Journal of Experimental Biology , 209 , 3629 - 3635, 2006) indicated that females of T. basalis are able to learn the features of their foraging environment and to adjust accordingly the amount of time spent on the patches of kairomones they are visiting, depending on whether or not host eggs are found. 3. In o…
Co-evolution between ectoparasites and their insect hosts: a simulation study of a damselfly-water mite interaction
2001
Summary 1. A simulation model investigating the co-evolution of water mites infesting their aquatic insect hosts during emergence is presented. The model is based on field and experimental studies of the ectoparasitic water mite Arrenurus cuspidator and the damselfly Coenagrion puella. 2. Three scenarios were studied: (1) Only the host was allowed to evolve timing of emergence, while the timing of the parasites' infestation opportunity was held constant. (2) Both host and parasite were allowed to evolve. (3) Only the parasite's timing was allowed to evolve, while the host was constrained completely. 3. In the first two scenarios, parasite abundances decreased in the course of evolution and …
<strong>Two new species of oribatid mites of the genera <em>Pergalumna</em> and <em>Carinogalumna</em> (Acari, Oribatid…
2014
Two new species of oribatid mites of the family Galumnidae, Pergalumna minituberculata sp. nov. and Carinogalumna alineata sp. nov., are described from soil of secondary mixed broadleaved forest with bamboo in eastern Nepal. The genus Carinogalumna is recorded for the first time in the Oriental region. Pergalumna minituberculata sp. nov. is similar morphologically to Pergalumna longisetosa Balogh, 1960 and Pergalumna paralongisetosa Ermilov & Kaluz, 2012, however, it differs from both by the body size, length of bothridial and adanal setae, absence of porose areas Ad, and the presence of notogastral setae c, medial pore, postanal porose area, striate genital plates and striate bands in anog…
Worldwide revision of the genus Phaenoglyphis (Hymenoptera, Cynipoidea, Figitidae, Charipinae)
2019
A complete revision of the world species of the genus Phaenoglyphis Förster, 1869 has been conducted. A total of 25 species of Phaenoglyphis are valid after studying their type material. Two new species are described: Phaenoglyphis belizini sp. n. and Phaenoglyphis palmirae sp. n. Two species are synonymized: P. dolichocera (Cameron, 1889) with P. nigripes (Thomson, 1877) and P. pecki Andrews, 1978 with P. villosa (Hartig, 1841). Phaenoglyphis bangalorensis Kurian, 1953 was considered as incertae sedis. Phaenoglyphis duplocarpentieri (Kieffer, 1904) and P. hedickei Hedicke, 1928 are considered lost. Other three species are discarded as valid species because they are missing important parts …
