False Spider

The Linotetranidae (Acari : Tetranychoidea) is a poorly known group of cryptic false spider mites associated with grasses and sedges. We review the family at the world level, provide the first phylogenetic analysis of the family, and describe the first Australian representatives: Austrolinus, gen. nov. and two new species: A.��arenulus and A. kinnearae. Linotetranidae is redefined, and keys are provided for the families of the Tetranychoidea, and for all described genera and species of Linotetranidae.

Two new species of the genus Aegyptobia Sayed and 1 new species of Phytoptipalpus Trägårdh are described from Iran:A. bromi sp. nov. from Bromus tectorum (Poaceae); A. nazarii sp. nov. from Poa bulbosa L. (Poaceae); and P.kurdistaniensis sp. nov. from wild rose bushes, Rosa woodsii (Rosaceae). This is the first record of Phytoptipalpus fromIran. We also redescribe Aegyptobia beglarovi Livschitz and Mitrofanov, 1967, A. persciae Khorowshahi and Arbabi,1997, A. tragardhi Sayed, 1950, and A. salicicola Al-Gboory, 1987; the latter species has only 2 anal setae and is thusmoved to Phytoptipalpus. Aegyptobia kharazii Mesa and Moraes, 2009 syn. nov. is regarded as a junior synonym ofAegyptobia beglarovi Livschitz and Mitrofanov, 1967; Aegyptobia ueckermanni Khorowshahi and Arbabi, 1997 syn. nov.is regarded as a junior synonym of Aegyptobia tragardhi Sayed, 1950; Aegyptobia daneshvari Parsi and Khosrowshahi,1990 syn. nov. is regarded as a junior synonym of Phytoptipalpus salicicola (Al-Gboory, 1987). A key to all known Iranian species of the genus Aegyptobia is provided.

False Spider Mite

False spider mites are serious pests of pomegranate and frequently cause considerable economic losses in other fruit crops as well. A field experiment conducted to evaluate eleven acaricides against Tenuipalpus aboharensis infesting pomegranate plants, revealed that wettable sulphur at 2.5 g and dicofol at 2.5 ml per litre were very effective and other acaricides viz. propargite, fenpyroximate, chlorfenapyr and buprofezin were also found effective against T. aboharensis.

Sex Ratio Adjustment

We tested predictions associated with three widely used hypotheses for facultative sex-ratio adjustment of vertebrates using eight enclosed populations of gray-tailed voles, Microtus canicaudus. These were (i) the population sex ratio hypothesis, which predicts that recruitment sex ratios should oppose adult sex-ratio skews, (ii) the local resource competition hypothesis, which predicts female-biased recruitment at low adult population density and male-biased recruitment at high population density, and (iii) the first cohort advantage hypothesis, which predicts that recruitment sex ratios should be female biased in the spring and male biased in the autumn. We monitored naturally increasing population densities with approximately equal adult sex ratios through the spring and summer and manipulated adult sex ratios in the autumn and measured subsequent sex ratios of recruits. We did not observe any significant sex-ratio adjustment in response to adult sex ratio or high population density; we did detect an influence of time within the breeding season, with more female offspring observed in the spring and more male offspring observed in the autumn. Significant seasonal increases in recruitment sex ratios indicate the capacity of female gray-tailed voles to manipulate their offspring sex ratios and suggest seasonal variation in the relative reproductive value of male and female offspring to be a regular phenomenon.

Sorex Cinereus

AbstractLarge aggregations of shrews have been reported and various explanations offered for this seemingly rare behavior; however, there has been little evidence to support any particular interpretation. We observed two small aggregations of highly active vocalizing Sorex cinereus while performing wildlife surveys in forested habitats in central Massachusetts, USA. These observations, in conjunction with a review of other reports, including genetic analyses, strongly suggest that such aggregations of adult Sorex are associated with mating behavior, more readily observed during periods of high population density. Published accounts of such behavior may be rare because primarily large aggregations have been reported; however, smaller breeding aggregations may be common.
