Anystis Baccarum

The Anystidae are a family of over 100 species of predatory mites commonly seen in soils and on plants worldwide. A few species of genus Anystis have potential as biocontrol agents against some insect and mite pests. Herein I provide a review of the lifespan of the Anystidae as part of a series on the lifespans in the Acari. The full life cycle in this family includes six immature stages (the egg, prelarva, larva, protonymph, deutonymph and tritonymph) and adult males/females. Life history data are only available for a few species. Developmental times from eggs to adults (44 to 82 days at 21 or 22 °C) were reported for three Anystis species. The total lifespan was measured for only one species (Anystis agilis): 66 days at 21 °C. There are two to three generations per year for Anystis species in the field. Summer aestivation was reported for Anystis baccarum, either as eggs or tritonymphs; aestivating tritonymphs may have a developmental time and total lifespan of over 200 and 300 days, respectively.

A New Species

A new species ofDikrellais described and figured based on specimens from Minas Gerais, Southeastern Brazil. The new species is diagnosed by the process of pygofer and the general form of aedeagus. Adult males, females, and also nymphs were found on pequi tree, suggesting thatDikrella caryocarn. sp. has its full life cycle in this plant.

Household electric blankets are widely used in China, but the problem of quality and safety is also more prominent, which is a serious threat to the health and safety of consumers. The structure characteristics and working principle of household electric blanket are analyzed. The hazards in the each stage of full life cycle are identified, including the stages of designing, manufacturing, packaging, transporting, utilizing and recycling. Hazard identification of each stage is made with methods of scenario analysis, safety check list, fault hypothesis analysis, hazard and operability analysis, failure mode and effect analysis and fault tree analysis, respectively.

Abstract Åström M., and Dekker W. 2007. When will the eel recover? A full life-cycle model. – ICES Journal of Marine Science, 64: 000–000: –. The European eel population has declined over the past decades in most of its distribution area, and the stock is outside safe biological limits. The EU has taken up the challenge to design a management system that ensures the escapement of 40% of spawning-stock biomass, relative to unexploited, unpolluted circumstances in unobstructed rivers. This ultimately aims to restore the spawning stock to a level at which glass eel production is not impaired, i.e. to restore to full historical glass eel recruitment. To explore the trajectory from the current depleted state to full recruitment recovery, we developed a simple model of stock dynamics, based on a simplified stock–recruitment relationship and the conventional dynamic pool assumptions. Recruitment trajectories under different future fishery regimes are explored, for the medium (one generation time) and long time-span (until full recruitment recovery). Reducing fisheries to zero, recovery is expected within ∼80 years, whereas under an ultimately sustainable fishing regime of just 10% of the current rate of fishing mortality, recovery may take more than 200 years. Moreover, management regimes, apparently leading to slight recovery of the stock in the coming 5–15 years, might still be unsustainable in the long run.
