The generic status of several species formerly placed in the genus Tibicen is reconsidered based on the recent erection of new genera as well as historical evidence. Subsolanus Moulds, 2015 syn. nov. is shown to be a junior synonym of Auritibicen Lee, 2015. Six species are reassigned from Tibicen to appropriate genera based on morphological characteristics.

The allocation of resources to male and female progeny is a major component of the reproductive strategies of all sexual plants and animals. Over the past 30 years there has been intensive theoretical and experimental investigation of how natural selection moulds the sex ratio. Here, we discuss recent exciting developments and new applications of sex allocation theory and highlight some unresol...

Objectives: The aim of the study was to describe the distribution of house-dust mite (HDM) allergens in homes of threeyear-old children and to test the hypothesis whether the content of HDM allergens exceeding 2 μg/g of dust may be regarded as a risk level possibly affecting respiratory health in early childhood. Materials and Methods: House-dust samples were collected in 275 dwellings from mat...

Raw milk is an ideal growth medium for microorganisms (including many fungal species), as such milk provides all necessary nutrients and conditions for their growth. The objective of the present study was to investigate the diversity of microscopic fungi in the milk obtained in Latvian organic farms depending on cow herd size and season. The study was carried out on 547 milk samples taken from ...

statement of the problem: insolubility is an important criterion for an ideal root-end filling material to both prevent any microleakage between the root canal and the periradicular space and provide sealing ability. purpose: many recent studies have shown that mineral trioxide aggregate (mta) and calcium-enriched mixture (cem) have acceptable sealing ability. the purpose of this in vitro study...

Aspergillus is the name used for a genus of moulds that reproduce only by asexual means. The morphology of the conidiophore, the structure that bears asexual spores, is the most important taxonomic character used in Aspergillus taxonomy. Aspergillus species are common and widespread. They are among the most successful groups of moulds with important roles in natural ecosystems and the human eco...

IN the dairy industry moulds are often encountered on media containing lactic acid. According to the literature on the subject, the view appears to be justified that this acid is oxidized by the moulds into CO2 or transformed into oxalic acid. Wehmer [1929] reports that by the action of Aspergillus mutantus calcium lactate is transformed into carbonate and sodium lactate into oxalate. Similarly...

Sorghum and pearl millet are two important dry land crops that provide grain and fodder. India is the largest pearl millet producer and second largest producer of sorghum in the world. The productivity of these crops has been low due to various reasons such as unavailability of quality inputs to the farmers, lack of access to improved technologies for crop production, unavailability of credit o...
