The efficacy of trunk treatment with three materials, cotton seed oil, lime and used motor oil, were evaluated for the control of apple clearwing, Synanthedon myopaeformis (Borkhausen) (Lepidoptera: Sesiidae) in an apple orchard during two successive years (2004 and 2005). The weekly total number of adult catches and exuviae was recorded each year. No treatments caused significant reductions in...

The genetic variability of honey bee populations of three subspecies selectively reared in Poland (A. m. carnica and A. m. caucasica) and Bulgaria (A. m. macedonica-type rodopica) was studied using isoenzyme analysis of six enzyme systems (MDH-1, ME, EST-3, ALP, PGM and HK) corresponding to 6 loci. All loci were found to be polymorphic in the studied populations. Three alleles were detected at ...

Background and objectives: Plants belonging to the genus Tilia L. (Tiliaceae) are often tall beautiful trees which are considered for various medicinal potentials of their flowers and leaves. The present study was an attempt to investigate the phytochemical constituents of Tilia rubra subsp. caucasica leaves from the hyrcanian forests of north of Iran. Methods: Chromatography on Silica gel (nor...

The millipede Typhloglomeriscaucasica Golovatch, hitherto considered as a troglobite confined to several caves near Sochi, western Caucasus, Russia, is recorded epigeically in the same region, and is therefore a troglophile.

1. The distinction between semelparity and iteroparity is one of the most fundamental in life-history biology. Despite an abundance of theory proposed to explain the evolution of this dichotomy, few quantitative empirical tests exist. 2. We report here on life-history variation in the perennial herb Arabis fecunda (Brassicaceae), in which differences in the frequency of iteroparity and terminal...

Generally, microbial control agents such as entomopathogenic nematodes are applied in a curative manner for achieving pest suppression; prophylactic applications are rare. In this study, we determined the ability of two Steinernema carpocapsae strains (All and Hybrid) to prophylactically protect peach trees from damage caused by the peachtree borer, Synanthedon exitiosa, which is a major pest o...

Two new species, Lasiopa aksarayiensis sp. n. and Lasiopa aktasii sp. n. are described from the Central Anatolian stepe in Turkey. All diagnostic characters are illustrated and possible relationships of both taxa are briefly discussed. The first record of Lasiopa pseudovillosa (Rozkošný, 1983) from Turkey is presented and additional Turkish localities of Lasiopa caucasica (Pleske, 1901) are rec...
